Wind and solar

The Internet is overflowing with articles about how renewable energy sources are increasing but they use a statistical trick by comparing percentage increase over last year. For example if solar provided 3% of the energy last year and this year it increased to 4% that would be reported as a 33% increase. The facts indicate a different story. According to a August 2022 article energy consumption and production contribute to two-thirds of global emissions and 84% of the global energy system is still based on fossil fuels, the same percentage as 30 years ago. Oil 33.6%, coal 27%, gas 24.2, hydro power 6.4%, nuclear 4.3%, wind 2.2%, solar 1.1%. Of these wind, solar and hydro power are considered renewables and hydro power will not be increasing so only wind and solar are available for growth and they account for 3.3% of the total. Here is a recent report from CNN. The world generated a record 10% of its electricity from wind and solar in 2021 and clean sources accounted for 38% of total power supply — even more than coal. This is another reporting trick. Note the word electricity. This does not include energy used in transportation. If that is added in total from wind and solar drops to 4%. Almost all of the articles on the Internet are written by wind and solar proponents.
