Renewables Can’t Power Modern Civilization Because They Were Never Meant To

Over the last decade, journalists have held up Germany’s renewables energy transition, the Energiewende, as an environmental model for the world. “Many poor countries, once intent on building coal-fired power plants to bring electricity to their people, are discussing whether they might leapfrog the fossil age and build clean grids from the outset,” thanks to the Energiewende, wrote a New York Times reporter in 2014.
With Germany as inspiration, the United Nations and World Bank poured billions into renewables like wind, solar, and hydro in developing nations like Kenya.
But then, last year, Germany was forced to acknowledge that it had to delay its phase-out of coal, and would not meet its 2020 greenhouse gas reduction commitments. It announced plans to bulldoze an ancient church and forest in order to get at the coal underneath it.
After renewables investors and advocates, including Al Gore and Greenpeace, criticized Germany, journalists came to the country’s defense. “Germany has fallen short of its emission targets in part because its targets were so ambitious,” one of them argued last summer.
But Germany didn’t just fall short of its climate targets. Its emissions have flat-lined since 2009.
Now comes a major article in the country’s largest newsweekly magazine, Der Spiegel, titled, “A Botched Job in Germany.” The magazine’s cover shows broken wind turbines and incomplete electrical transmission towers against a dark silhouette of Berlin.
“The Energiewende — the biggest political project since reunification — threatens to fail,” write Der Spiegel’s Frank Dohmen, Alexander Jung, Stefan Schultz, Gerald Traufetter in their a 5,700-word investigative story.
Over the past five years alone, the Energiewende has cost Germany €32 billion ($36 billion) annually, and opposition to renewables is growing in the German countryside.
“The politicians fear citizen resistance” Der Spiegel reports. “There is hardly a wind energy project that is not fought.”
In response, politicians sometimes order “electrical lines be buried underground but that is many times more expensive and takes years longer.”
As a result, the deployment of renewables and related transmission lines is slowing rapidly. Less than half as many wind turbines (743) were installed in 2018 as were installed in 2017, and just 30 kilometers of new transmission were added in 2017.
Solar and wind advocates say cheaper solar panels and wind turbines will make the future growth in renewables cheaper than past growth but there are reasons to believe the opposite will be the case.
Der Spiegel cites a recent estimate that it would cost Germany “€3.4 trillion ($3.8 trillion),” or seven times more than it spent from 2000 to 2025, to increase solar and wind three to five-fold by 2050.
Between 2000 and 2019, Germany grew renewables from 7% to 35% of its electricity. And as much of Germany’s renewable electricity comes from biomass, which scientists view as polluting and environmentally degrading, as from solar.
Of the 7,700 new kilometers of transmission lines needed, only 8% have been built, while large-scale electricity storage remains inefficient and expensive. “A large part of the energy used is lost,” the reporters note of a much-hyped hydrogen gas project, “and the efficiency is below 40%… No viable business model can be developed from this.”
“The wind power boom is over,” Der Spiegel concludes.
No amount of marketing could change the poor physics of resource-intensive and land-intensive renewables. Solar farms take 450 times more land than nuclear plants, and wind farms take 700 times more land than natural gas wells, to produce the same amount of energy
The reason renewables can’t power modern civilization is because they were never meant to. One interesting question is why anybody ever thought they could. (Read More)
