If you put solar panels and wind turbine on every street light and put centers on them so lights only come on when cars or people are on street you would save a lot of power you could power city’s and towns for free and maybe make money if you put turbine in gravity freed water lines for towns you creat power for free you want more power built more turbines on dams you could get 3 to 4 times more power for same water used from 1 dam
