I spent most of last week or two reading about climate change and came across a path for cutting US emissions that I really liked: https://medium.com/otherlab-news/how-do-we-decarbonize-7fc2fa84e887.
“The beginning and the first half of decarbonization will most likely look the same: a commitment to solar and wind [zero-carbon electricity], batteries, electrification of homes, heat pumps, electric vehicles [electrification]…” The author, energy inventor Saul Griffith, then shows this needs to be done on a massive scale in the US: just focusing on 3 key steps, we need 200m+ electric vehicles, electric heating systems for 120m+ homes and 5m+ commercial buildings, and 2 TW of zero-carbon electricity production (mostly solar/wind because they’re cheapest, with variation based on locale).
I don’t think this is new, but seeing that a large fraction of emissions could be reduced by just a handful of steps was extremely clarifying. I think parts of this approach are already happening in the US (growth in number of solar rooftops to about 1m), although maybe not at a fast pace. I also haven’t looked into the negative consequences of this path (not just carbon but other environmental impacts of e.g. producing so many electric vehicles).
If this is a good path, it seems likely that policy, operations, engineering and financing elements could help, including potentially large workforces to manufacture the cars, heating systems, batteries, solar panels and wind turbines; and definitely large workforces to install, maintain and connect these elements. Operations, engineering and financing might be grouped into centralized businesses like SolarCity (which “markets, manufactures, and installs residential and commercial solar panels”), but they don’t have to be (e.g. many local contractors around the country). Owners might just pay for these electric vehicles and heat pumps like they pay for their current vehicles and furnaces, but financing (or straight up donation?) might be important for big solar/wind projects and for people unable or unwilling to switch to electric appliances. Policy seems like it could help by providing such financing (e.g. a Fannie Mae for these clean techs), by requiring zero-carbon electricity (e.g. renewable portfolio standards) and/or electrification, and by making sure local regulations are compatible with solving climate change (e.g. building codes).
Now, what can individuals or small groups additionally do to accelerate this? I know I’m focused on pandemics with most of my time now, but if this is a good path, I want to spend some time on this.
1. Cancer immunology or immunology more generally may be relatively crowded fields for me to enter as a biology researcher; however, there might be other reasons to enter anyway.
“As of June 2018, there were reported to be some 940 new immuno-oncological drugs being tested for breakthrough designation and FDA approval. Another 1,064 new immunotherapy drugs are in the labs in preclinical phase. That’s 2,004 new cancer drugs in just a few short years. This speed of change is highly unusual in medicine, and totally unprecedented in cancer. And by the time you read this, those numbers and the science behind them will have advanced again.”
“There are now reportedly 164 PD-1 / PD-L1 drugs in the pipeline between preclinical testing and consumer marketing, and industry insiders suspect there may be many more being developed in China.”
“The result is billions of dollars and scores of talented specialists now devoted to cancer immunotherapy. The funding torchbearers of the field such the Cancer Research Institute, started more than seventy years ago by William Coley’s daughter, have been joined by new organizational infrastructures to support that work, among them the Biden “moon shot” Cancer Initiative, to rethink medicine as a whole, and cancer most specifically; the Parker Institute for Cancer Immunotherapy to fund and coordinate researchers and clinical trials as never before; public appeal drives such as Stand Up to Cancer; (SU2C), which directs hundreds of millions of donated dollars directly into research and clinical trials; and a gold rush for commercial pharmaceutical companies and startups and the dozens of biotech venture capitalists that fund them. Several researchers have quipped that there are now two types of drug companies: those that are deep into cancer immunotherapy, and those that want to be.”
There are many caveats with my claim. Perhaps there is a ton of work left to be done to make immunotherapy promising, and immunotherapy is that good of a tool to have against cancer or pandemics. Maybe a bunch of money and industry interest are incoming, but there is still a bottleneck in innovative research. In computational research specifically? Is there a bottleneck in research talent in either (e.g. maybe there aren’t many people who have been trained in certain skills or types of research in cancer immunotherapy or immunology)? And, as always, beware statistics. However, I do tend to think that, with so much funding and hype around the field, there’s bound to be some incoming research talent, including computational talent. I would be willing to bet on myself as being able to advance immunology or cancer immunotherapy, at least marginally, but I’d also bet that I could advance other fields by more. However, for my PhD research choice, this may be outweighed by factors by aiming to be in a top lab or being in a field that is (currently) prestigious and reliably funded.
I am now more interested in immunology that engineers the immune system. See Preface below for my mixed feelings about the promise of this approach vs. say broad-spectrum antimicrobials. I guess that means understanding how it works, but in a focused way. I think you should argue as a prior that it’s hard to predict where the next finding from immunology will come from and it won’t necessarily follow the past, but if the past is some indication, I do think that empirical work, including the flavor of work of Allison and hx, is more robust. As opposed to “epistemic base” flavor stuff, specifically molecular-level speculative biology. Also, note that you might want to engineer the immune system to go stronger or weaker (again, how do the pathogeneses work?).
2. Cancer immunotherapy is currently very expensive. (This might be worth trying to solve.)
As of 2018, “[p]ricing for Yervoy—the trade name for the anti-CLTA-4 drug ipilimumab—is typical, costing more than $120,000 for a four-course treatment. Merck’s anti-PD-1 drug Keytruda, for advanced melanoma, costs $150,000 for a yearlong treatment.”
3. Cancer is potentially not as much a death sentence as I imagined.
“Until very recently we’ve had three main methods for treating cancer… These ‘cut, burn, and poison [surgery, radiation and chemotherapy]’ techniques are currently estimated to be able to cure cancer in about half of the people who develop the disease.” However, Graeber doesn’t provide much backing for this estimate. Is it true? I feel some doubt. The word “cure” seems strong; a cross-check with https://slatestarcodex.com/2018/08/01/cancer-progress-much-more-than-you-wanted-to-know/ suggests ~50-70% as a 5-year survival rate across cancers (the percentage of people who survive five years after being diagnosed with cancer), which is less than a cure but still pretty good. Maybe a majority of those 5-year survivors were actually cured and never experienced a remission. It’s unclear.
4. Maybe consider or ask about cancer immunotherapy, on its own or in combination with other therapies, if you or someone you know gets cancer (I’m not a doctor).
“[Ipi] was an immediate game changer, reducing deaths from late-stage melanoma by 28 to 38 percent. The first phase 1 clinical trials started in 2001, long ago enough to qualify 20 to 25 percent of those patients with “long-term survival” benefit. That’s still less than half of the patients, but a great deal better than the low single-digit survivor percentages only the year before.”
“There are now at least half a dozen approved anti-PD-1 / PD-L1 drugs… The anti-PD-1 / PD-L1 drugs seem to work best if a patient’s tumor is expressing PD-L1. For that subset of patients, the drug has worked well, providing durable and sometimes complete responses.”
This section will become out of date as new trials come out. I can only speculate on whether immunotherapy will offer improvements for other cancers in the coming years.
5. One might imagine cancer as analogous to viral infection; both involve potentially hijacked cells creating many other hijacked cells (cancer by outgrowing normal cells, virally infected cells by spreading viral particles). I should read about how both of these cause diseases and their pathogenesis. Without knowing anything, I can imagine that they cause disease by (a) creating big masses in your body through uncontrollable replication and/or (b) decreasing your normally functioning cells via infection and/or outcompetition.
6. I have a bias against engineering the immune system instead of letting it perform naturally unless it’s an emergency and the alternative is clearly worse; this bias is confirmed by this book. Two notable emergencies:
- You’re clearly going to die of cancer without treatment (the book’s subject).
- It’s a deadly pandemic (e.g. case fatality rate > 25%) where traditional vaccine approaches don’t work, so you should try some of the less tested approaches to immunotherapy that have been tried in cancer. Approaches mentioned in the book include
- vaccines or live infection
- passive immunization via transfusion of serum/blood, antibodies or T cells
- adoptive T cell therapy (a cellular therapy, i.e. drug is a cell)
- checkpoint inhibitors (T cell-specific)
- broad stimulants of the immune system or parts of it (e.g. interferon, IL-2 or TCGF for T cells)
- CAR-T cells
- bispecific antibodies to chain T cells with cancer or infected cells
- ways to make cancer or infected cells express unique antigen to be visible to the immune system
- 50+ targets in the tumor microenvironment
- oncolytic virus therapy
- combinations of such with existing therapies and each other
- You could consider these in combination with the suite of antimicrobials as the tools in our arsenal in a pandemic:
- antivirals (e.g. ART)
7. I learned various things related to
- the standards needed in experiments to prove various findings in cancer immunotherapy
- the strategies for discovery of such findings
- the stories behind key concepts in immunology
- various wet lab techniques
- pictures of certain phenomena
These may be expanded and may be of interest to fellow scientists.
8. Below, I outlined my favorite parts of the book as it fits my background and interests. This may be helpful to those only interested in specific questions or sections, as well as those who have read the book and wish to have a mental map of its contents. I think those interested in the bioscience and clinical aspects (e.g. point 7) will enjoy reading the book in full. I think others will benefit from just a summary, which can be found in Appendix B of the book.
- Preface. Argues that, to treat cancer, it is better to use the immune system than to use a typical drug, because the immune system adapts against cancer’s mutation, unlike a typical drug. Even though this is true, isn’t it possible that the immune system is already doing what it can to fight a disease, so there may be little to gain my engineering/optimizing it further? I agree that there’s a clear optimization for immunocompromised people (get them off immunosuppressants or fight their HIV/AIDS) but otherwise it’s not obvious to me that just because the immune system is strong and adaptive, that we should be looking to further engineer it to do better.
- Chapter 1 Patient 101006 JDS
- Chapter 2 A Simple Idea
- Chapter 3 Glimmers in the Darkness. How we know how the immune system works (“In retrospect… horrible, glaring exception”). People seeing immune system not working against cancer as proof of its non-relation. Some Rosenberg and cancer immunologists’ stuff in 1970s-1990s (Coley repeat but with serum/blood transfusion instead of infection, then a more specific transfusion of T cells created by pig in response to tumor, then IL2-fertilized T cells plus IL2 (accidentally discovered in 1976 as fertilizing healthy T cells in an attempt to grow leukemia, more appropriately T-cell growth factor for crazy T cell growth numbers, produced beyond scarcity with rDNA spurred by interferon, the 1957-discovered “interfering” hormone) <1/2 helpful study followed by news and FDA approval but difficulty in reproducing and more scientists avoiding immuno for cancer area) (“In 1968… the most successful would be the ones who weren’t even trying.”) So Rosenberg and previous era can be thought of as a. IL2, b. maybe cancer vaccine (mash up tumor), c. serum and/or T cell transfusion [b. and c. having analogs for infectious disease, a. is a new idea that didn’t pan out so well, vs. these checkpoint inhibitors which may pan out reasonably well].
- Chapter 4 Eureka, Texas. Jim Allison. How do T cells recognize and get activated at all? Find TCR, then CD28, then co-inhibitor CTLA-4.
- Chapter 5 The Three E’s. This is basically immuno again but maybe post-Allison and the author trying to go back and forth and/or put things chronologically, I’m not sure what the logic of the order is (1974 Stutman nude (non-immune) vs. normal mice getting carcinogen and same tumor rate; 1988 Schreiber and Old TNF and IFNy knockdowns (genetic mutation, antibody) stop immune response, incl. vs Meth A tumor model and carcinogen-induced tumor mice; fight between cancer and immune system (elimination, equilibrium, escape) and survival of the fittest tumors (name “immunoediting”) portrayed by taking out immune system and tumors suddenly overwhelming previously healthy (mutagenized) mice and by transplanting tumors from immunosuppressed/competent mice to the other, respectively, with checkpoints being possible tumor tactic and other ways to engineer immune system). Story of ipilimumab (Allison’s anti-CTLA4 antibody for desperate metastatic melanoma, w/ BMS unsure about continuing, S vs. PFS vs. feeling better, side effects, approval in 2011, etc.).
- Chapter 6 Tempting Fate. Mostly the anti-PDL1 approval story (“On December 10… [end of chapter]”). It’s also Brad (“[beginning]… help Brad save his”) and discovery of PDL1 (“Like most big discoveries… side of the handshake followed quickly behind”).

[Highly speculative post]
Would a universal basic income (a plan for the government to pay everyone, say, $1k/month) decrease greenhouse gas emissions? The thought occurred to me because I’ve been trying to cap my emissions for a while and quickly realized that I was only able to keep my energy usage below the average global citizen’s level because I didn’t have to drive 20 minutes to work each day, which otherwise would explode my energy usage. This is possible in Boston, especially when you have housing options within 20 minutes’ walking distance from your place of work. But I had a harder time imagining this working in the sprawling South Bay in the San Francisco Bay Area (although you can get surprisingly far with a bike). Reading about basic income made me think: if basic income resulted in some people quitting their jobs, and if quitting your job means reducing your emissions spent on driving to work, does basic income win on this environmental count as well?
Yes, I realize this is speculative. Basic income might have to be pretty high, or your cost of living pretty low, for a basic income to convince you to leave your job. (Andrew Yang’s $1000/mo. Freedom Dividend, while a start, feels insufficient.) And while I do *feel* that quitting your job reduces your emissions, maybe you spend your leisure time or your low-cost lifestyle driving an equal or even greater amount to other places instead. I doubt it, but it’s possible.
Two speculative arguments make me feel that no job is less energy-intensive than a job:
- I saw inventor Saul Griffith show a graph of how energy usage is correlated with GDP. The 2008 recession saw a significant dip in energy usage. I would guess that that happens because lower GDP means fewer transactions, sales and jobs, and (a) people are just doing and making less stuff, (b) fewer people are coming to work and (c) people are spending less on carbon-expensive vacation flights. The first two of these factors pertain to a basic income scenario, and suggest a link between fewer jobs and fewer emissions.
- I read about this terrifyingly energy-intensive job in David Graeber’s _Bullshit Jobs_:
Kurt works for a subcontractor for the German military. Or… actually, he is employed by a subcontractor of a subcontractor of a subcontractor for the German military. Here is how he describes his work: The German military has a subcontractor that does their IT work.The IT firm has a subcontractor that does their logistics.
The logistics firm has a subcontractor that does their personnel management, and I work for that company.
Let’s say soldier A moves to an office two rooms farther down the hall. Instead of just carrying his computer over there, he has to fill out a form.
The IT subcontractor will get the form, people will read it and approve it, and forward it to the logistics firm.
The logistics firm will then have to approve the moving down the hall and will request personnel from us.
The office people in my company will then do whatever they do, and now I come in.
I get an email: “Be at barracks B at time C.” Usually these barracks are one hundred to five hundred kilometers [62–310 miles] away from my home, so I will get a rental car. I take the rental car, drive to the barracks, let dispatch know that I arrived, fill out a form, unhook the computer, load the computer into a box, seal the box, have a guy from the logistics firm carry the box to the next room, where I unseal the box, fill out another form, hook up the computer, call dispatch to tell them how long I took, get a couple of signatures, take my rental car back home, send dispatch a letter with all of the paperwork and then get paid.
So instead of the soldier carrying his computer for five meters, two people drive for a combined six to ten hours, fill out around fifteen pages of paperwork, and waste a good four hundred euros of taxpayers’ money. What the…?
Obviously not all jobs are so energy-inefficient, but even a job in which you drive 20 miles to the office, sit in an air-conditioned office for 8 hours and then drive back is pretty energy-intensive. This makes me feel that not having a job is often less energy-intensive than having one.
This leaves me more stuck on the first objection that current proposals for universal basic income would not influence many to quit their jobs.
Besides reducing my energy usage, I’ve been thinking a lot about pandemics for my PhD research. Is it crazy that basic income might also be helpful in that scenario? Specifically, imagine the next Spanish flu emerges. It threatens to spread to every continent within weeks, and, if the world responds to it as it responded to the 1918 version, 3-5% of the world population will die. So the CDC and WHO and a bunch of scientists and companies around the world scurry to make a vaccine, but that’s going to take hundreds of days. The main way for the rest of us to stay safe and stop the spread in the meantime is to stay away from each other and from our offices and schools. Except many need to go to work to pay the rent and eat…
Universal basic income to the rescue! You may now consider not going to work if you’re really concerned about the pandemic. You may lose your job, but you hopefully can still pay your rent (depending on where you live in the United States), and maybe you get your job back when the pandemic is over. Again, however, as with the emissions case, the basic income amount may not be enough for this to make sense.
Thinking about this made me wonder about a pandemic basic income, which is an income administered to everyone in pandemic situations for this very reason. I don’t think most pandemics warrant this kind of panicked response, but if one really did, maybe you’d want a pandemic basic income (plus other measures in place to ensure food, clean water and a bunch of other services still get to people despite the social disruption).
Note: When I try to imagine the rest of my lifetime, I feel pretty optimistic. It’s not that I believe that poverty will magically go away or that people aren’t already feeling and won’t continue to feel some of the impacts of climate change. But I do generally speculate that we won’t see a huge pandemic, nuclear war or similar humanity-devastating outcome.
Even though such risks seem unlikely, I have generally felt that they are still worth mitigating given their seriousness if they do happen. I think this explains my interest in the area, which has driven me to work on a couple projects in biosecurity and pandemic preparedness in my PhD. This post lays out lines of reasoning that have influenced my changing feelings about the seriousness of pandemics.
I first learned about pandemic risk from the Open Philanthropy Project (OPP). According to OPP, “[t]he worst flu pandemic in the past century was the ‘Spanish’ flu epidemic of 1918, which is believed to have been responsible for about 50 million deaths,” or 3-5 percent of the world population at the time . The academic biosecurity community  in general fears that modern pandemics have the potential to kill even larger percentages: increased travel and other factors potentially augment the risk, while modern medicine and public health knowledge potentially decrease the risk.
How serious is pandemic risk, versus the 30-40 million people who die each year of non-communicable diseases , or climate change, or poverty and improved economic well-being (e.g. housing prices)?
tl;dr: At least 2 historical pandemics killed > 3% of the global population within a few years; extrapolating this gives a death toll of > 210 million people today, which in rate terms is an order of magnitude less than that of non-communicable diseases. When considering modern factors that increase pandemic risk (see Red Note), along with the suddenness of pandemics and several scenarios that are worse than historical ones, pandemic risk seems as or more serious to me than suffering from non-communicable diseases.
(Note 1: Comparing pandemic risk and non-communicable diseases does not make me feel, “Oh, non-communicable diseases aren’t that bad.” Like many, I have had family members die and/or suffer from such diseases. This comparison makes me feel, “Wow, surprisingly this problem feels as or more serious than one I already feel is incredibly serious; I should seriously consider working on it.”)
(Note 2: I recommend the 106-minute movie _Contagion_ and, if you have more time, Laurie Garrett’s book _The Coming Plague_ for vivid (and realistic) depictions of pandemics that go beyond the mainly quantitative arguments below. For more background on the specific pandemic threats that could lead to different numbers of deaths including the ones below, as well as actions that can be taken to mitigate such threats, I recommend the 80000 Hours’ podcasts and OPP cause report .)
My feelings about seriousness of pandemic risk
1. I first imagined a scenario in which Spanish flu today kills the same percentage of the world population as it did in 1918. That’s 210-350 million deaths (3-5% of the world population) . The Institute of Disease Modeling performed simulations of a modern Spanish flu (presumably accounting for modern factors like increased air travel and more advanced medicine); this 15-second simulation predicted 33 million deaths in the first 6 months:
This IDM number seems significantly lower than the 3-5% extrapolation. Using the 3-5% extrapolation or the IDM results, one modern Spanish flu would kill as many people as non-communicable diseases do in about 5-8 years or 1 year, respectively. If such a Spanish flu happens once or even twice in my lifetime, then in relative terms, the impact is an order of magnitude smaller than that of non-communicable diseases. I dislike engaging in such speculative estimates, but I see no other way to get an intuitive grasp of how serious the problem is. These estimates made me feel the problem is still extremely serious, but less relatively serious than I had initially thought.
2. At this point, I was surprised and asked why I had previously felt so sure that pandemic risk was as or more serious than non-communicable diseases. I then realized that my comparison of total numbers between the two problems missed part of the picture:
- Many factors increase pandemic risk and magnitudes in the future .
- The worst past pandemic is not a worst case bound on future pandemics, even if such factors don’t end up increasing pandemic risk. I can’t just hope that the worst or average case death toll for a future pandemic is the Spanish flu number (3-5% of world population) or even the Black Death number (until I know more about how these numbers were estimated, I’m not going to put much faith in them, but Wikipedia  estimates 16-23% of the world population). Pandemics seem like forest fires in their potential to scale unpredictably and uncontrollably beyond what one might expect : infectious agents self-replicate just like fires, with billions of proximate humans constituting the firewood.
- Pandemics unpredictably kill a bunch of people at once; this seems worse than something that kills the same number at a slow, steady rate. I mean “worse” in the sense of denting humanity’s trajectory, by unpredictably killing many people of child-bearing age in a short timeframe . In the case of Black Death, “[i]t took 200 years for the world population to recover to its previous level.”  In contrast, many of the non-communicable diseases are diseases of old age; they seem to kill no more than a fixed percentage of the world population in predictable ways. This is not captured in comparison of raw numbers.
3. These arguments make me feel again that pandemic risk is extremely serious, at least on par with the suffering caused by non-communicable diseases.
My attitude towards personally working to mitigate pandemic risk
Guided by my interest, I try to pick what to work on based on the seriousness of the problem, how many people are already working on the problem, whether I can actually contribute to the problem and other hard-to-name factors called “personal fit.” The above post only addresses the first factor. At this point, I remain reasonably interested in working to mitigate pandemic risk, as well as other biosecurity risks.
0. Bill Gates paints the picture of a pandemic here:
1. From my current understanding, the academic biosecurity community includes people at the Johns Hopkins Center for Health Security, the Nuclear Threat Initiative, the Open Philanthropy Project and quite a few other institutions. See https://80000hours.org/podcast/episodes/beth-cameron-pandemic-preparedness/ for a full list.
2. This was generated from http://ghdx.healthdata.org/gbd-results-tool:
3. See https://80000hours.org/podcast/episodes/we-are-not-worried-enough-about-the-next-pandemic/ (“When we talk about biosecurity and pandemic preparedness… something even scarier”), https://80000hours.org/podcast/episodes/beth-cameron-pandemic-preparedness/, https://80000hours.org/podcast/episodes/tom-inglesby-health-security/ and https://www.openphilanthropy.org/research/cause-reports/biosecurity.
4. I don’t know about how the Spanish flu or Black Death death toll estimates are made, so I take them with a grain of salt. However, to take pandemic risk seriously, I don’t require the numbers to be that exact, given that such large numbers are plausible to me based on the exponential nature of pandemics and the huge variance in modern pandemic death tolls, and especially given multiple instances of global pandemics in history.
5. I think there are many factors; ask me if you’re interested. As mentioned before, there are also factors that potentially decrease modern pandemic risk, such as advanced medicine and public health knowledge. I won’t delve into it here, but my feeling is that factors increasing risk outweigh those decreasing it.
6. “In total, the plague may have reduced the world population from an estimated 450 million to 350–375 million in the 14th century.” 75-100 million / 450 million = 16.67-22.22%. https://en.wikipedia.org/wiki/Black_Death.
7. I first heard the pandemic-forest fire analogy from Marc Lipsitch.
8. It’s true that flu usually kills the extremely young or old, not those of child-bearing age. I would guess this is due the stronger immunity of young adults and middle-aged people. However, Spanish flu is a notable exception.
I’m trying to reduce my energy usage to the level of the average global citizen’s. [**EDIT**: I am now tracking how well I’m doing that here.]
I was inspired to do so by renewable energy inventor Saul Griffith. In 2009, he gave a talk about climate change (http://longnow.org/seminars/02009/jan/16/climate-change-recalculated/):
“[Saul Griffith]’s been analyzing his own life in extreme detail to figure out exactly how much energy he uses and what changes might reduce the load. In 2007, when he started, he was consuming about 18,000 watts, like most Americans. The energy budget of the average person in the world is about 2,200 watts… [T]o stay at the world’s energy budget at 16 terawatts, while many of the poorest in the world might raise their standard of living to 2,200 watts, everyone now above that level would have to drop down to it.”
Well, how much can I reduce my energy usage?
I estimate that I
could easily be am at ** 3,000 1,689 (3,385) watts** (the latter number tries to also very roughly account for my portion of energy used by my country’s government and energy used by the education, finance and healthcare services I use). , plus my portion of heating for the dorm I live in and the places I work [no longer in a dorm and don’t use house heat]. (I will update this with numbers when I hear back from my dorm building manager.)
3,000+ 1,689 (3,385) watts is:
1. *Flights*: Jet fuel for
1 2 roundtrips from SF to Boston each year ( 385 771 watts)
2. *Land transport*: Gas for 1 8 mi roundtrip on a bus from Boston to Cambridge each week (225 watts)
3. *Stuff*: Energy for production and transportation\* of my laptop and phone, toiletries, clothes, miscellaneous items and the trash these produce (270 watts)
4. *Food*: Energy for production and transportation\* of 1 serving of milk per day, 1 serving of fish per month and 10 servings of vegetables per day (425 watts)
5. *Heat and electric*: Electricity and gas for
heating of my dorm and workplace, refrigerator, cooking, laptop and phone (34 watts plus my portion of heating)
6. *Services*: Energy for production, transportation and retail of the healthcare, education and finance services I use (1080 watts)
7. *Society*: My portion of the energy spent by the US government, notably the construction of roads and the purchases and operations of the US military (464 watts)
8. *Buffer*: Things I forgot to count, plus miscellaneous things here and there that aren’t recurring or significant uses of energy (e.g. a random drink of wine over the holidays) (151 watts)
What would I have to change in my life to get to
3,000+ 1,689 (3,385) watts? **I’d start by cutting flights, cars/buses and bought stuff, the highest bang-per-buck areas** for me and Saul (and, I suspect, many of my friends). I actually don’t have that much to cut to get to the lifestyle described above, minus a few things:
1. For 2019, I’m planning on traveling once to Peru for vacation and once to home over the holidays. Re Peru: In general, I’d need to do such vacation travel very infrequently, or replace the holiday trip home with one to a vacation destination.
2. I’d have to cut three trips per week to Cambridge (which I did in Fall 2018) down to one. I could accomplish this by coordinating all my meetings and activities to happen on one day per week, participating in others remotely instead of in person, prioritizing which activities in Cambridge are truly important to me and potentially staying over in Cambridge.
3. I’d have to reduce buying from Amazon (I count 19 orders over 17 weeks in September to December 2018) with the wish list method\*\* or by buying used things, which seems like a great and fair-accounting way to reduce energy usage.
4. Less important things: I could take cold showers exclusively, which I occasionally do for the thrill and am curious to turn into a habit.
5. Relatively easy things: I’d have to continue my habits of not buying recurring new things except food and toiletries (e.g. no recurring clothes!), not buying non-essential things (e.g. no physical books), not buying new big things (e.g. furniture), not using the heat in my room (wear warm clothes or insulate the room instead), etc.
I’ve posted the details of my accounting here, including the numbers I used for energy usage of each lifestyle item or action: https://docs.google.com/spreadsheets/d/1c5741VO0wBtWL5ph4E6APThuwR7lF-LH6arTxPXlv3g/edit?usp=sharing.
How accurate are the numbers I’m using for energy usage per lifestyle action or item? I haven’t checked them myself, but I somewhat don’t care about the exact numbers, because the direction is correct (i.e. using/doing less means reducing your energy usage), and the general action item remains the same: **travel less and buy fewer things and services.** I *do* care about not forgetting my sources of energy usage (e.g. I forgot about electricity for lighting the first time around), and I especially care about not forgetting the biggest contributors. I also care that the numbers’ orders of magnitude are correct. I am inclined to trust Saul’s numbers because he seems to be very rigorous and detailed. You can judge for yourself by watching Saul’s talk (http://longnow.org/seminars/02009/jan/16/climate-change-recalculated/, especially 47:46-51:00) or his other talk (https://www.youtube.com/watch?v=1ewEaTlGz4s, especially 31:00-35:00), which he apparently prepared by combing through 60,000 pages of footnotes of energy data.
If you’re interested in making these calculations for your life, I’d recommend watching 47:46-51:00 in Saul’s talk to get an overview of the process: http://longnow.org/seminars/02009/jan/16/climate-change-recalculated/ \*\*\*. Then you could use a spreadsheet similar to mine. My spreadsheet has some common line items (e.g. watts for air or car travel) but excludes others that aren’t part of my life (e.g. my room came furnished, so I haven’t bought furniture). Your lifestyle likely has different stuff and actions than mine; to find the numbers of watts for these things or actions, I’d recommend referring to Saul’s slides, which are in high definition here: https://www.dropbox.com/s/86tfvc6mm5gbbv9/longnow16jan09-090905230147-phpapp01.pdf?dl=0. Specifically, pages 75, 79 and 81 are useful for watts on overall goods and services, food and physical goods, respectively. I tried searching for an online energy usage calculator but couldn’t find one\*\*\*\*. If there’s a number you’re looking for that isn’t in Saul’s slides, you might find it in this MIT climate course lecture, although I haven’t looked at the lecture myself and didn’t use it for my calculations: https://ocw.mit.edu/courses/chemistry/5-92-energy-environment-and-society-spring-2007/lecture-notes/energy_calc_guid.pdf.
Am I uncomfortable making these cuts in my life? For me, I’ve always been a pretty cheap homebody. I spend a lot of time using the computer (for work, reading or chatting with friends) or taking walks with nearby friends. I hate owning too many things because I dislike spending mental effort tracking them. So the ideas of living minimally have been easy for me to adopt, and the environmental argument for living this way is a cherry on top. For me, the most difficult sacrifice of these cuts is not flying home more often to see my family and close friends, but I see this as solvable by making my trips home longer and getting better at having a deep relationship remotely, with gifts, cards and quality time online. According to Long Now, after Saul’s cuts, “[h]e’s healthier, eats better, has more time with his family, and the stuff he has he cherishes.” I think that many people would similarly find that living in a lower-footprint way would change their lives in other ways that matter to them, sometimes positive and sometimes negative. If those changes are positive, then these “cuts” will look more like improvements and tend to stick.
I don’t want to say that there’s no environmental motivation for what I’m doing. While I’m not under the illusion that the cuts in my life will, by themselves, put a dent into climate change, I hold out some hope that I will figure out a way to have a larger impact on climate change. Living this way is potentially educational in that endeavor and could make me more credible to have that kind of impact. Moreover, it could be that developed-world citizens *must* make this magnitude of cuts (and/or make up their carbon footprint in some other way\*\*\*\*\*) for it to even be feasible for renewable energy to scale to cover the world’s energy usage. Something just resonates emotionally with me when I hear Saul make this argument, even though he says it in such a nonchalant way (to see him say it with graphics, start at 46:46 in http://longnow.org/seminars/02009/jan/16/climate-change-recalculated/):
“So you now realize that the 18,000 watts or 17,000 watts in Saul Griffith’s life looks a little like extravagant, because if everyone in the world went from 2,500 watts to 18,000 watts suddenly, we are not going to need to have just Renewistan [Saul’s imaginary planet that produces the world’s 2009 energy consumption, 16 TW, from renewable sources]; we are going to need 6 or 7 Renewistans. That’s not going to scale. So it’s inevitable that China and India bring their power consumption per capita up, and probably we shouldn’t begrudge anyone in the less developed nations to do so. And that sort of means that we [developed-world citizens] have to go down.”
If everyone has to make these cuts, then in particular, I have to make these cuts.

\*\*\*\* Saul created such a calculator called WattzOn at some point before 2009, but I wasn’t able to find the calculator today (in 2019). It used to exist, because I found it on Wayback Machine: https://web.archive.org/web/20120212172149/http://wattzon.com/track-and-monitor; however, the calculator doesn’t seem to be functional on Wayback Machine.

As a Philanthropy Fellow for Harvard Effective Altruism, I had the opportunity to get dinner with MIT physicist Max Tegmark and the other Fellows on Tuesday evening. We had a fascinating discussion about existential risks and the reasons that much of the public today does not even think about the destructive potential of such risks as unfriendly artificial intelligence (AI), while just 50 years ago during the Cold War people all over the world actually felt and believed in the real possibility of human extinction. Max noted that the Cuban Missile Crisis and realistic movies about nuclear war (such as TV shows like Threads) played a large role in making the public aware of these threats, which suggests that films about unfriendly AI, the first of which seems to be the upcoming film Transcendence, could spread public awareness about current existential risks.
I also learned a lot about cosmology from Max’s fascinating talk related to his book Our Mathematical Universe; I’ve posted notes for the talk here. If you find the notes interesting, definitely check out his book, which Ben recommends as an excellent read.
Earlier this month, I posted on the Tech in the World blog about what the team and I learned about Tanzanian culture in our first week here in the country. Our team is learning more about Tanzanian culture everyday! Here are more tidbits, many taken from a conversation with our Dar es Salaam Institute of Technology (DIT) contact Ashery:
- The average marriage age 25 for men and 22 for women.
- Younger Tanzanians really like to listen to hip-hop and their own, smoother version of R&B called bongo-flava (see this song by Diamond, one of the most popular bongo-flava artists here). In fact, artists like Jay-Z, 50 Cent and Busta Rhymes have performed here. Apparently many students at DIT like Rick Ross.
- I asked Ashery about Tanzanians who are admired by the general Tanzanian public. Ashery said that Julius Nyerere, the country’s founder, ranks pretty highly on that list because he managed to instill in the citizens a pride about their identities as Tanzanians, rather than as members of different tribes (there are more than 260 tribes) and different religions (40 percent Muslim, 35 percent Christian, and 20 percent Animism). One way he accomplished this was by including each group in his government (it just happens that presidents have alternated between Muslim and Christian for the last few terms) and his socialist message for equality. According to Ashery, this has been important to avoid the tribal infighting—political and violent—that has occurred in neighboring countries like Kenya (during election time) and Rwanda. Ashery (who is Christian) got really excited when he was saying this, pointing to his friend Abdul (who is Muslim) and saying that in Tanzania, different people coexist peacefully. Maybe Julius Nyerere has a biography worth reading.
- Presidents Clinton, Bush (Jr.), and Obama have all visited Tanzania, and the citizens of Dar es Salaam got so excited that many of them left work to see the presidents.
- David Cameron, the UK prime minister, has threatened to withhold aid from countries that criminalize same-sex marriage and other activities, which include Tanzania. Tanzania reacted strongly and is in fact relatively intolerant of homosexuality, as evidenced by Pew Global Attitudes survey that found that 95 percent of Tanzanian residents believe homosexuality is a way of life that society should not accept (the seventh-highest rate of non-acceptance in 45 countries surveyed). Ashery said that there has been much debate about this.
That’s all for now!
I lie on my bed with my Macbook in front of me, writing a reflection on my first week in Tanzania. Feeling uncomfortable, I toss off my bednet, get off the bed and sit in a nearby chair, bringing my laptop over. I touch one of the ridges of my laptop. Ouch. Did that hurt? I can’t really tell, and touch it again. Is that how the ridge normally feels? It’s a bit sharp. Confused, I ask my roommate Erik to join me in touching the laptop. He (being the electrical engineering major) immediately pulls my Macbook charger out of the laptop and recoils upon touching the tip. “Static shock!” he says. “Really?” I say.
We begin to diagnose the problem. My charger is connected to a 6-outlet power strip and international adapter that we bought yesterday in a Tanzanian supermarket, which is connected to the wall. One of these is broken. Suspecting the Tanzanian-made power strip, we start testing all the outlets on the power strip and even substituting in one of our own power strips. But with each touch of the charger’s tip, we get shocked in greater disbelief. I begin to suspect my charger itself. Indeed, after plugging Ruth’s Macbook charger into the power strip, the shock is gone. So much for my Mag “Safe” Power Adapter; it probably suffered under the strain of Tanzanian humidity and the 240V outlets.
The shocking is entertaining though, so we bring another Tech in the World Fellow—Ramya—over to join in our discovery. Plugging my charger back in, I offer her the charger tip. She takes it in her hand, but… nothing. In confusion, I touch it but feel nothing! Erik finally touches it and recoils. Ramya and I look quizzically at Erik (who seems to be doubting his own senses), but he continues touching, and recoiling from, the charger tip. Ramya and I try again and again but just can’t figure out how to shock ourselves. Erik suddenly says, “Take off your shoes.” I kick off my flip flops and feel the cool tile floor, touching the tip again. Ouch!
This is the first in a series of short stories I am posting about my time in Tanzania as a Tech in the World Fellow. Stay tuned!
Bajajis (also known as tuk-tuks or rickshaws in India) are phenomenally nimble three-wheeled taxis. Ramya tells me that the tuk-tuk drivers in India are daring and skilled at navigating very chaotic traffic at high speeds. In Tanzania, these bajajis are our cheapest way to get around, so naturally they are the first type of transportation we try.
We’re going out to dinner at a beach restaurant; Google Maps says it’s 2 kilometers away. We wave over a bajaji and, in our broken Swahili, ask the driver to take the six of us to the restaurant:
Me: Mbalamwezi? Elfu tatu? [Name of the restaurant. Three thousand schillings.]
Driver: Four thousand [Tanzanian schillings]. Six of you.
Me: [Thumbs up.] [To other TITW students:] Let’s go.
We cram into the bajaji, three of us in the back seat and three of us sitting on the others’ laps. Already we get the premonition of this safety hazard leading to a road accident; our combined weight seems to precariously tip the bajaji from left to right as the driver begins to move. But the driver assuages our fears as he drives swiftly ahead—our forward velocity seems to straighten out our wobbliness (I know I’m in a safe spot in the bajaji anyway, since I am squished underneath Ruth and won’t go flying out the window).
We continue swiftly until we hit traffic, and the two-lane roads give us no option but to sit and wait. At least that’s my thought as I peek out from behind Ruth at the crowded street. But the innovative bajaji driver sees an “opening” on the pedestrian sidewalk to our left (the “sidewalk” is a 10-foot wide dirt strip on either side of the road). Seven men and women walk towards us on the sidewalk 200 meters away, but the daring bajaji driver decides to plow ahead on the sidewalk, passing the sitting cars to our right. He accelerates swiftly left and immediately we drop onto the sidewalk (which is not quite level with the road). The ride on the rocky, unpaved sidewalk is precarious—our heavy bajaji, stuffed with six people, tips ominously from left to right between a sewage ditch and other vehicles, including these big dala dalas. Each of us holds in the simultaneous excitement and terror we feel (with the exception of a few shrieks) as we swing from side to side, narrowly miss the oncoming pedestrians, and turn back into an opening in our original lane.
As exhilarating as driving on the sidewalk is, it feels safe to be back in the correct driving lane. But we hit slow traffic again. This time, our driver sees a new opening right about 10 feet wide, right in between the two directions of traffic. We swerve into this “lane” as cars brush by us on both sides as quickly as 40 mph. Our lane is so narrow that I can touch the dala dalas on our left as we pass them.
Our roller coaster ride ends as we see the beach restaurant on our right. As we continue to use bajajis as our main mode of transportation, I wonder how much more dangerous it really is to ride a bajaji here than it is to take a taxi in the United States. The notion of personal space is relaxed here (in fact, it is considered rude here to stand too far away from someone you’re greeting), and personal space on the road has been no exception. I have a hunch that the probability of getting into an accident in a bajaji here is not significantly different from the probability for taxis in the US, but that many of my US friends would perceive the difference to be pretty high upon reading this story or watching a video of a bajaji ride because of the close quarters in which Tanzanians drive and live.
Just as my US friends would perceive a bajaji to be much less safe than it actually is because of their discomfort with lack of personal space, I think that I and many of my friends overestimate our personal need for our own space, possessions, and privacy in the US relative to how much we actually need to be satisfied. An American culture that supports having your own car, house, and computer doesn’t help; examples of my desire for privacy this past year included the need for a single in my dorm, the need to have my own laptop (which I realized I didn’t actually need for most of my life while using a school computer), and the need to do yoga in my private space of my room (instead of at the gym). Yet living in Tanzania has showed me that I can live without “personal” everything and not lose much in the way of my values of personal growth and achievement. I’ve acclimatized to intimate working conditions, public transportation (including the people packed onto dala dalas—imagine 30 people fitting into this Toyota passenger bus), and dependence on the environment outside my possession and my fellow students for everything from food to sunscreen, power adapters, and money. I’m curious to exchange personal space and possessions for other things that may achieve my values better when I return to life in the US.
