Nuclear plants necessary to reduce greenhouse gas emission: McCarthy

WASHINGTON (US) – Gina McCarthy, White House national climate adviser said that the existing nuclear power plants are going to be needed in the Biden administration’s effort to hit goals to reduce greenhouse gas emissions.

“In many areas continuation of the existing nuclear, as long as it’s environmentally sound and it’s permitted, is going to be absolutely essential” because it will provide time to develop renewable energy into a bigger part of the energy mix, McCarthy said at a Columbia University Center on Global Energy Policy virtual event.

The White House signaled privately to lawmakers and stakeholders recently that it supports taxpayer subsidies to keep aging nuclear facilities from closing as shutdowns make it harder to meet U.S. climate goals.

President Joe Biden wants to set the country on a path to decarbonize the energy grid by 2035 and last month set a goal to cut U.S. emissions by 50%-52% from 2005 levels by 2030. That would be roughly a doubling of a previous goal set by former President Barack Obama.

In addition the administration supports a clean energy standard in the infrastructure plan, a mechanism that could help support existing nuclear power as well as carbon capture and sequestration to be added to fossil fuel plants.

“It’s a very stable baseload system,” McCarthy said about generation of electricity from nuclear plants, which generally operate all day, unlike wind and solar power which can be intermittent if not backed up by robust batteries.

Nuclear power is virtually free from carbon emissions that cause global warming, but is still rejected by some environmental groups because of concern over the disposal of toxic waste.

The United States has 93 nuclear reactors, more than any other country, but nuclear power capacity peaked in 2012. Some reactors have closed due to high security costs and competition from natural gas plants and renewable power.

A report by the International Energy Agency on Tuesday said almost 90% of global electricity generation should come from renewables by 2050 and most of the rest from nuclear.
