The article cites research publication by Stanford University professor of civil and environmental engineering Mark Z. Jacobson, very famous 100% wind, water, and sunlight (WWS) advocate.

His past research was already cited by Leonardo DiCaprio on Sept. 23 2014, during opening of the UN Climate Summit.

“The good news is that renewable energy is not only achievable but good economic policy,” DiCaprio told the more than 120 world leaders assembled. “New research shows that by 2050 clean, renewable energy could supply 100 percent of the world’s energy needs using existing technologies, and it would create millions of jobs.”

The 100% renewable papers by Mark Z. Jacobson were subject to strong criticism. Jacobson filed a lawsuit in 2017 against the Proceedings of the National Academy of Sciences and Christopher Clack as the principal author of the paper for defamation. In February 2024, Jacobson lost the appeal and was required to pay defendants more than $500,000 in legal fees.

Jacobson is also very strong critic of nuclear energy. In calculating CO2 emissions from using nuclear energy, he includes carbon emissions associated with the burning of cities resulting from a nuclear war aided by the expansion of nuclear energy and weapons to countries previously without them.

Jacobson assumes that some form of nuclear induced burning that will occur once every 30 years.
