Lots of options. That’s good. Sedans, SUV, Trucks, BEV to gas..

I am lucky to live the Pacific Northwest, Wa state- lots of hydro, wind and solar. 73% of energy is clean. Cost per kWh $0.11.
We had a head start, lots of rivers and dams, rain a lot, lots of elevation change. The nation wide trend is to higher % of clean energy. In any case my cost per 100 miles is $2.55, but that’s for a small sedan.

I wonder when the average for the US is 70% clean energy. Nationwide coal electric plants are being replaced with wind and solar to lower KWh cost.

Battery performance is trending to better- 1/4 the cost or 4X the range within 10 years? Check out Li air.

Battery expected life of LFP is now 1,000,000 miles, up from 300,000 to 500,000 for early 2012 EV models.

Trends are good.

I wish we would see a faster pace of clean energy solutions.
