Here's a start I guess:
Some places you can tell your electricity provider that you want to opt for
green/renewable power service. All that means is that you want them to
fulfill your electricity use by purchasing power from renewable
providers ... wind, solar, geothermal etc. There's a very minor cost
premium on your bill that gets noted. Less than $3 a month in most
places. The more people order green power, the more they buy and the
more the price will come down.
