Air pollution
Air pollution from burning fossil fuels kills 8.7 million people each year. We homed in on over 9,500 point-sources located in urban areas that expose a disproportionate number of people to PM2.5

~45% of US corn production is now used to make ethanol, mostly for mixing into gasoline.
That's ~13% of all US crop land already used for energy production.
Using some of the same land for solar panels would capture 50-100 times more energy per acre.
