CSP Barriers and Obstacles
Location must be in the desert Southwest Unlike solar PV, CSP can’t cope with humidity or cloud cover, so it is limited to the southwest were the solar irradiation is high and there is no dust, haze, or smog. Solar … Continue reading

Not enough wind, solar, geothermal to replace fossil and nuclear power in the 11 western states of the WECC
California, Oregon, Utah, and Washington have already developed most (if not all) of their prime-quality in-state resources. You would think that the more wind and solar power is added over a wide area, the more fossil fuel power plants you … Continue reading
