Each terawatt-hour of coal kills 15 people [1]. How often does Folding@home burn through a terawatt? Well, 1000 megawatt-hours is one gigawatt-hour, and 1000 gigawatt-hours is one terawatt-hour, and 1000×1000=1,000,000, so how fast does Folding@home burn through 1 million megawatt-hours? Each year, Folding@home uses 15×24×365.25=131,490 megawatt-hours, or 131.5 gigawatts, or 13.15% of a terawatt-hour. Each terawatt-hour means, remember, 15 dead people; in our grim calculus, what is 13.15% of 15 dead people? 1.8 dead people.
So if the power is entirely derived from coal, Folding@home kills 2 people a year. … The EIA says the average US rate for 1 kilowatt-hour in November 2010 was $0.0962. A megawatt-hour is 1000 kilowatt-hours, so 1 megawatt-hour is 1000×0.0962, or $96.2, so 15×96.2 = $1443/hr. And its annual bill is 1443×24×365.25, or ~12,650,000 dollars per year3.
$12.65 million is a lot of money. What could we do with that? Meta-charity Givewell estimates that <$1000 could save one life; another source says “Cost-effectiveness estimates per death-averted are $64-294 for a range of countries”[2]. (One modest proposal is to use this $1000 figure as the base unit of a new coinage: the DC or ‘dead child’; it has the merit over the dollar of possibly ingraining an understanding of opportunity costs.) And these interventions are the kind of things that can absorb a lot of money. (There are a lot of people out there who could use some help.)
If <$1000 will buy 1 life, then $12.65m would buy ~12,650 lives.
