I like the idea of moving toward a self sustaining solar/wind/ homestead. People can grow most of their own food in their backyard. We need to foster that into our culture. Growing plants and trees absorbs carbon, which lowers greenhouse effects. A whole community doing this could be very effective. If you have a small yard you can use staggered shelving to grow a ton of food in potted plants. Done properly a small, well run homestead can produce much of its own food and energy. You just need to get out of in front of Jersey Shore or Glee, get off your fat rump and DO IT.
Instead of building huge homes with little tiny back yards, where one could feasibly pee from the back door to the property line, build a smaller home on a bigger lot where people can grow their own food, a few trees and install some solar and wind options too. How about a community rain water storage facility? Instead of having a set of CC&R's that choke you to death, how about a set of CC&R's that require wind, solar and homestead-like options? If people don't want to do it they can live elsewhere.
