Global Power Demand Is Soaring, IEA Expects 4% Growth in ’24 & ‘25
Even though the supply of new renewables (wind, solar, new biofuels) rose impressively, about 50-fold, during the first 20 years of the 21st century, the world’s dependence on fossil carbon declined only marginally, from 87 percent to 85 percent of the total supply, and most of that small relative decline was attributable to expanded hydroelectrici

Two prominent examples illustrate this unfolding material dependence. No structures are more obvious symbols of “green” electricity generation than large wind turbines—but these enormous accumulations of steel, cement, and plastics are also embodiments of fossil fuels.[107] Their foundations are reinforced concrete, their towers, nacelles, and roto

In 1995, crude oil extraction finally surpassed the 1979 record and then continued to rise, meeting the demand of an economically reforming China as well as the rising demand elsewhere in Asia—but oil has not regained its pre-1975 relative dominance.[49] Its share of the global commercial primary energy supply fell from 45 percent in 1970 to 38 per

Hydro generation accounted for nearly 16 percent in 2020; wind and solar added almost 7 percent; and the rest (about two-thirds) came from large central stations fueled mostly by coal and natural gas.
