You hear the terms off-grid, smart-grid and renewable, but what does it all mean.  Most of us are connected to a power grid that gets its energy from coal, nuclear, or hydroelectric dams.  But as companies are realizing the effects of carbon emissions on the world they are looking at more sustainable and renewable technologies like wind and solar power.  The problem with renewable sources is they are intermittent and thus smart grids can come into play.  Read more at or the  US Dept of Energy (and opportunities through the Recovery Act)
