For some reason, the following article from EcoWatch and the NRDC made me think of something that sounds like greenschist:
Top 10 States Leading the Renewable Energy RevolutionBy Ralph Cavanagh
California continues to lead the way on clean energy, but energy efficiency and renewables are gaining major ground across the country, a new ranking of states and cities shows. Six states now get at least a fifth of their power from non-hydro renewable sources such as wind and solar—further confirmation that regardless of the Trump administration’s efforts to promote fossil-fuel interests, clean energy is making undeniable inroads.
The Golden State and Massachusetts lead the eighth annual U.S. Clean Tech Leadership Index from the research firm Clean Edge for a fifth year in a row, the latter bolstered by its strong record of energy efficiency and private investment in clean tech. Vermont, Oregon and New York round out the top five.
I just couldn’t resist comparing electricity prices to the “Clean Tech Leadership Index” (CTLI) and I was not disappointed. Six of the ten States with the most expensive electricity are in the CTLI top ten.
Oregon and Washington benefit from massive hydroelectric resources, while Hawaii and Alaska have expensive electricity due to their remoteness. So, I cross-plotted electricity prices vs. CTLI for all 50 States and 46 States (deleting AK, HI, OR & WA).
