Very conservatively solar produces 30-50 times are much energy per acre as corn ethanol. I think if you consider just the ethanol to mix with gas vs charging an electric car with solar it's a 100 times more.

Something around 2500W of solar can provide enough energy to drive an EV 12,000 miles a year.

When it comes to zoning. The state should require offices to install chargers for employees cars when the solar share of electricity generation is highest.
