Will it clean the streets as it drives?

Power production costs on a decreasing trend. Cheaper natural gas, more renewables.

For Corporations Acquiring Renewables, It’s Not All About Price. That’s reasonable. This is not: “Energy and utility companies were the least likely industry to say their company would be more assertive in acquiring renewables in the next two years. Only 37.5 percent of those companies said they wanted to become more aggressive in purchasing renewable energy.”

Marginal health costs of microscopic particulate matter may be decreasing in their density in the air. This is opposite of what you probably expect. It means that the greatest health benefits (per person) may be had by decreasing PM2.5 in areas where it is already low. Taking into account the fact that populations are highest in Indian and China, where PM2.5 is high, it may still be most worthwhile to decrease levels there.
