Black Swans and Greenwashing Solar and Wind

Finally a truth teller!! Khosla puts his money where his mouth is as a major investor in green technologies. He has enormous credibility.

Solar and wind power? Off-cycle - they generate peak power at mid-day or at night, not at the time of peak demand. Energy storage at a scale required to meet demand is not economic in most places.

CNG or hydrogen? CNG uses 4x the volume of liquid fuels; would you buy a car with no trunk? Free hydrogen hardly exists in nature, and producing it takes more energy than it delivers.

Let's hope Vinod is heard before our esteemed Congress appropriates funds to support more dead-end technologies.
