i’ve been asked if buying green power makes a difference. here in los angeles we get almost 65% off all our electricity from coal fired power plants. thought that coal did not exist in CA, you would be correct. while most of the locally generated power is from natural gas, los angeles bought long ago into the intermountain generating station power plant in utah, which is coal fired, and thus produced a lot a acid rain, deforestation, and mahem. would it make sense to buy green wind and solar power. absolutely.
