"Annual reduction of 17 million metric tons of CO2, which is, based on the central estimate of the social cost of carbon, "equivalent to an annual global benefit of $700 million."
Annual reductions of "10,000, 10,300, and 1,200 metric tons of SO2, NOx, and PM2.5, respectively ... which provide annual domestic air quality benefits of $890 million."
Annual water "withdrawal and consumption savings of 294 billion gallons (0.8% of power sector total) and 7.6 billion gallons (0.5% or power sector total), respectively, with much of those savings located in drought-impacted California."
It's worth keeping in mind that the somewhat clinical phrase "domestic air quality benefits" is another way of describing fewer kids having asthma attacks, fewer adults missing workdays, and fewer people dying of respiratory and circulatory ailments.<p>It's also worth keeping in mind that none of these social benefits are priced into the cost of solar; it is not compensated for its "positive externalities." If it were, it would knock almost 5 cents a kilowatt-hour off the price, which would mean the Sunshot cost target was already achieved."
