If only coal is considered, it doesn't look good. My math may be way off, but: coal: 1,933,130,000,000 kwh/yr plants: 518 kwh/plant: 373,191,120 tons/plant: 4

If only coal is considered, it doesn't look good.
My math may be way off, but:
coal:
1,933,130,000,000 kwh/yr
plants: 518
kwh/plant: 373,191,120
tons/plant: 4,000,000
ton/kwh : 0.01
37.4% of electricity in US
nat. gas:
.0005675 ton/kwh
30.3% of electricity in US
tesla S:
.3kwh/mi
Coal only: .003 ton/mi
Gas only: .00017 ton/mi
Coal + Gas + Renewables: 0.0012 ton/mi
avg ICE:
12,000 mi/yr
5.1 ton/yr
0.000425 ton / mi
As we move away from coal and towards renewables, it's obvious that electric cars become the winners. In areas with mostly coal power production, though, ICEs are more environmentally friendly.
It's really telling how freaking dirty coal is.
