I am fortunate enough to live in Del Sur, a community that actively supports the green effort.  The community is required to have at least 20% of the homes be under solar power.  Also mandatory tank-less water heaters and weather-based satellite irrigation systems are in most homes. These water-saving systems can potentially save up to 40,000 gallons of water per home per year. The community also requires that at least half of all landscaping be drought-resistant, and reclaimed water is used in community landscaping.  I was just curious to see if anyone else lives in a community like this or what their community does...
