The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

We already have 95% of the technologies and know how to slash emissions, remove air pollution and provide energy security and jobs

No, we don’t need ‘miracle technologies’ to slash emissions — we already have 95 percent, The Hill 20th May 2021, Mark Jacobson: We have 95 percent of the technologies we need today and the know-how to get the rest to address both energy and non-energy emissions.


As such, no miracle technology, particularly carbon capture, direct air capture, modern bioenergy or modern nuclear power, is needed. By implementing only clean, renewable WWS energy and storage and implementing non-energy strategies, we will address not only climate, but also the 7 million annual air pollution deaths worldwide and energy insecurity.

None of the “miracle technologies” addresses all three. We and 17 other research groups have shown that we can do it with renewables alone worldwide and in the 50 United States. Such a transition reduces energy costs, and land requirements while creating jobs.

The key is to deploy, deploy, deploy existing clean, renewable, safe technologies as fast as possible.

U.S. Climate Envoy John Kerry recently stated, “I am told by scientists that 50 percent of the reductions we have to make to get to net zero are going to come from technologies that we don’t yet have.” This comment echoes recent statements by Bill Gates that solar, wind and batteries are not enough, so we need “miracle technologies” to decarbonize our global economy. They also mimic statements in a 2021 International Energy Agency report that, “in 2050, almost half the reductions come from technologies that are currently at the demonstration or prototype phase.” One might argue that, in all three cases, “new technologies” means improved existing technologies, such as improved
batteries, solar panels, wind turbines, electric vehicles, etc.

However, hidden in the recent U.S. economic revitalization proposal is a call to fund CO2 capture and storage, CO2 direct air capture and small modular nuclear reactors. Similarly, Gates has funded and argued for these technologies plus modern bioenergy, and the IEA report explicitly proposes the use of all four technologies for a decarbonized world. Ironically, the IEA acknowledges, “all the technologies needed to achieve the necessary deep cuts in global emissions by 2030 already exist.” But astonishingly, they then say that those technologies and their improvements are not enough to reach 2050 goals.
