80% Renewable Energy by 2050 is Possible, Just Using Today's Commercially-Available Technology

While more research into improving renewable energy technology is certainly a good thing, a new report from the National Renewable Energy Laboratory shows that even if we just had today's cleantech for the next 40 years, we'd still be able to supply 80% of our electricity from low-carbon sources. Climate Progress does a good job breaking down the report, outlining the different scenarios presented by NREL, so I'll refer you there for the majority of the details. Under the 80% scenario, wind power is the single-largest energy source, roughly 35% of electricity, biomass is roughly 20%, solar power (PV and concentrating) is a bit over 10%, as is hydropower, nuclear power and coal hanging in there at just under 10%, with geothermal and natural gas in the low single digits. The key take-away for me is the same point CP is highlighting: We don't need some crazy cool new technolo...
