Here’s small factoid that i overheard at the 2014 CBJ Green Symposium this morning. There are many people who worry about solar PV’s impact on the grid, and in storing the day’s production for use at night and during cloudy days. In contrast, there is some data that shows that if renewables (solar, wind, etc) are widely distributed and there is a good power transmission infrastructure between all of these distributed generation centers, the need for grid-based energy storage goes way down. Basically, there will be generation somewhere, and what is needed is to ship that energy around instead of needing to store it all locally. Note that there will be a need for some storage, just maybe not as much as many people believe.
