Today in Cleantech

Renewable energy is in the news. Yesterday, Google revealed that it invested $38.8 million in wind projects through its philanthropic arm. Also, San Diego-based Envision Solar, maker of the Solar Tree system that doubles as a carport, went public, but with a twist. And in Florida, 1,370 billboards will double as highly visible distributed renewable energy nodes thanks to a DoE grant. While the $12.5 million project from Lamar Advertising is only expected to produce 1 megawatt, the sheer exposure could make it worth every penny.
