Graph shows that the expected change in the temperature of Earth is expected to rise in the next 100 years? I'm no 'global warming hipster', but please also remember that the emission of greenhouse gases, pollutants, etc., etc. affects much more than just the temperature of Earth. Just looking at the temperature of Earth without taking into account the various other externalities is a shallow argument. There have been various studies conducted in which the cost of damages from fossil fuel exploration, consumption and emission were quantified and those costs are in the range of $0.03/kWh for coal and $0.16/kWh for NG (compared to virtually nothing for nuclear, wind and solar). It would be wise to look to the quantified costs of externalities when weighing the LCOE for each technology. All that said, I'm a firm believer in a combined energy mix that consists of NG and solar - and especially once battery storage becomes more widespread/mainstream. Don't kid yourselves, there's a reason why FPL is the largest owner of wind energy facilities in the United States (and second in the world). Also, Duke just purchased a majority stake in one of the largest U.S. solar installer firms (REC Solar) and Duke owns a commercial renewable portfolio that totals about 1.8 GW of solar and wind. Take a look at what Georgia Power is doing as well. The utilities may be slow, but they're quickly realizing the importance of a diverse energy mix that includes non-traditional forms of power generation.
