Or we could solve it without geoengineering for about $10T. 30TW of carbon free power, 300TWh of storage, convert vehicles to EV as they're replaced, planes to hydrogen, convert heating to heat pumps as they're replaced.
$10T is about the cost of a major war. Eminently doable.
- rootusrootus 2y agoThe difference between 10T and 10B is approximately 10T. That’s pretty significant. And the 10T plan requires a great deal more participation from every single citizen. Good luck.
- bryanlarsen 2y agoThe difference is that $10T is an investment that pays returns -- 30GW of power plants generate electricity for ~free once they're built. In the long run, that $10T will be paid back and then some. OTOH the $10B is an annual expense with no return.
- rootusrootus 2y agoSure, but you can spend 10B a year for a thousand years and you still won't be anywhere even approaching 10T in today money. We could just do both and it would cost the same, for all practical purposes. In any case, if those power plants have a great ROI, they will get built very quickly without having to be publicly subsidized.
- sillywalk 2y agoNone of those actually reduce CO2 in the atmosphere, and the amount of emissions to produce them are substantial.
