The chart below dramatically underscores why the CO2 witch-hunt is such a deadly threat to future prosperity and human welfare. To wit, even after decades of green energy promotion and huge subsidies from the state, renewables accounted for only 5% of primary global energy consumption in 2019 because:
- They are still very un-competitve (high cost) relative to the installed base of fossil, nuclear and hydroelectric energy; and,
- They do not really even account for the 5% share reflected in the chart in terms of ability to delivery work to the economy owing to intermittency of wind and solar power and the fact that by convention government scorekeepers gross-up renewable electrical power delivered to end users by a factor of 3X to account for generation heat rate losses and transmission and distribution losses in the electric power grid.
By contrast, the 84% share attributed to oil, natural gas and coal is actually far larger in practical terms. That’s because most of the prime hydro sources have been tapped out long ago and are therefore not a meaningful source of growth. During the last 10 years, for example, US hydro-power output has only increased from 275 billion KWh to 288 billion KWh or by barely 0.24% per annum.
