Electric cars are coming. Right now, the electrics that youâ€™d want to drive cost too much. But those prices will come down. Are we ready to switch from gasoline to electric?
On average, ~50% of Americaâ€™s electricity is generated from coal. Californiaâ€™s largest source of electric power is natural gas, and generates only ~1.5% of its power from coal. But, if you buy your electric car in Indiana, youâ€™ll be trading your gasoline for electric power which is more than 90% generated from coal.
Now, Iâ€™m just doing fuzzy math, making simple assumptions based on some published statistics. My numbers could be wrong (perhaps electric cars are charged at night, and the profile of energy sources at night is different than what is consumed today). Maybe someone smart can correct me on that.
But on the surface, it doesnâ€™t seem to me that switching from gas to electric will make our skies cleaner. Why do many states and governments offer rebates to switch?
Others have noticed this problem too.
