Here's a great Greenvention that anyone with internet access can use. There's a new program for Google Earth (you know, that interactive program where you can zoom in on anywhere in the world and see actual satellite photos of the geography, but usually just end up honing in on your own apartment building or childhood home) that integrates a slew of data from the EPA to map out environmentally relevant sites across the US. That's right, you may as well call it Green Google Earth. And the best part is, anybody can hop on and use it.

The main focus of the feature is displaying sites that have a high potential for renewable energy development?you can set filters to look at different kinds of wind power, solar power, and biomass sites on the 3D map.

Also noted are things like superfund sites, abandoned mines, and brownfields ?the prime areas for renovation and installation of top renewable energy technologies. Those areas are particularly well suited for alternative energy projects since they're unfit for conventional development?and therefore in lower demand, and cheaper to build on.

So if you're curious about the lay of the land for renewable energy, download this cool green Google Earth application and take a peek.
