Energy researchers say nuclear power is ‘critical’ in effort to fight global warming

Published

Since the 2011 Fukushima Daiichi nuclear accident in Japan chilled global attitudes toward nuclear power, the world has been slowly reconciling its discomfort with nuclear and the idea that it may have a role to play in reducing greenhouse gas emissions to tackle climate change.

The International Energy Agency and the Nuclear Energy Agency suggest in a report released Thursday that nuclear will have such a significant role to play in climate strategy that nuclear power generation capacity will have to double by 2050 in order for the world to meet the international 2°C (3.6°F) warming goal.

With fossil fuels growing as sources of electricity across the globe, the IEA sees nuclear power as a stable source of low-carbon power helping to take polluting coal-fired plants offline.

To accomplish the needed CO2 emissions cuts to keep warming no greater than 2°C, the IEA says global nuclear power generation capacity needs to increase to 930 gigawatts from 396 gigawatts by 2050. With nearly 100 nuclear reactors, the U.S. has more nuclear power plants than any other country, representing 105 gigawatts of production. France, Japan, Russia and China round out the top five countries using nuclear power.

Globally, nuclear energy is already making a comeback with 72 nuclear reactors now under construction worldwide, mainly in Asia.

“This marked the greatest number of reactors being built in 25 years,” IEA Executive Director Maria van der Hoeven said in a statement. “Nuclear energy also remains the second-largest source of low-carbon electricity worldwide. And, indeed, if we are to meet our collective climate goals, nuclear energy is critical.”

All forms of low-carbon energy must be employed to reduce global greenhouse gas emissions, she said.

That conclusion is consistent with the Intergovernmental Panel on Climate Change’s findings last year that global carbon dioxide emissions need to be capped at 450 parts per million in order to prevent warming greater than 2°C,Robert N. Stavins, director of the Project on Climate Agreements at Harvard University and a drafting author of the IPCC’s Working Group III Report, said.

“It is virtually inconceivable that the 2 degree or 450 parts per million target as a cap can be achieved in this century without a variety of factors, among which are substantially greater reliance on nuclear power than current trajectories would suggest,” Stavins, who is unaffiliated with the IEA’s report, said.

Charles Kolstad, professor of economic policy research at Stanford University, suggested the IEA’s conclusions may be too strident.

“Nuclear is not necessary to meet any target except the most stringent,” he said. “The IPCC relies heavily on CCS (carbon capture and storage). Nuclear would certainly help, though.”

That’s because global power demand is growing and nuclear is a good alternative to coal, the main source of power in parts of the world where cheap natural gas is unavailable to replace coal, he said.

The IEA said nuclear reactor safety issues raised by Fukushima can be addressed by strong regulations, independent regulators, a culture of safety surrounding nuclear plants and the development of new safety technology, the report says.

China is leading the globe in nuclear energy expansion with plans to grow its nuclear power generation capacity to 59 gigawatts in 2020 from 17 gigawatts in 2014. Nuclear represents only about 2 percent of China’s total power production, but it has 29 nuclear reactors under construction.

The status of nuclear power is more mixed in Europe, where it is about 25 percent of total electricity production. Four new reactors are under construction in Europe. While Germany, Belgium and Switzerland are phasing out nuclear power altogether, Poland, Turkey and the United Kingdom are planning to expand the use of nuclear power.

The U.S., produces about 19 percent of its electric power with its 100 nuclear reactors. But most of its existing nuclear reactors are more than 30 years old. Only five new ones are under construction today and five others have been decommissioned since 2013.

Nuclear power expansion overall in the U.S. is expected to be flat in the coming years because of high costs of new nuclear development and the low cost of natural gas from shale, a formidable and quickly growing competitor to nuclear and coal for electric power generation. The report says that makes it unlikely nuclear will play a significant role in U.S. climate strategy anytime soon.

“It’s obviously not going to happen in this country,” Christine Todd Whitman, co-chair of the nuclear power advocacy group Clean and Safe Energy Coalition and former New Jersey Governor and former U.S. Environmental Protection Agency chief, said.

Nuclear reactors currently operating in the U.S. need to remain running in order to meet the Obama administration’sgreenhouse gas reduction goals, but the nuclear industry needs to drive home the message that natural gas and renewables may be insufficient for the U.S. to slash emissions adequately to tackle climate change, Whitman said.

Today’s political climate in the U.S., with Congress generally hostile to the EPA’s strategy to cut greenhouse gas emissions, is not lending itself to quick expansion of nuclear here, she said.

“I hope it will change to the degree it makes it easier for nuclear power to continue to develop in this country,” Whitman said.

Hope Hicks may have lied under oath that she wasn’t present when Trump and Cohen discussed Stormy Daniels

Published

on

Newly unsealed documents in the campaign finance case where Michael Cohen pleaded guilty may provide evidence that Hope Hicks lied to Congress under oath.

According to the court documents, President Donald Trump, Hope Hicks and Cohen were all in communication about the hush-money payments to adult film star Stormy Daniels. Not only did Hicks discuss the payments with both men, she exchanged text messages and emails on the topic.

White House aides fear Trump believes House vote against impeachment means it’s never going to happen: report

Published

on

A proposal to start impeachment hearings that failed in the House on Wednesday led Donald Trump to optimistically proclaim that his presidency is safe at his North Carolina rally last night. But his proclamation has some White House officials worried the president really believes he is out of the woods.

According to a report at Politico, close aides to the president worry that his comment that "we have all this [impeachment] behind us," may be based on an unfounded notion by Trump about how Congress works.

Speaking at his campaign rally in Greenville, N.C., Trump boasted to the crowd, "I just heard that the United States House of Representatives has overwhelmingly voted to kill the most ridiculous project I’ve ever been involved in: the resolution -- how stupid is that -- on impeachment. I want to thank those Democrats because many of them voted for us, the vote was a totally lopsided 332-95-1.”

Trump campaign refuses to disavow crowd’s racist ‘send her back’ chants

Published

on

NPR reporter Tamara Keith on Thursday asked the Trump campaign if it wanted to disavow the racist "send her back" chant directed at Rep. Ilhan Omar (D-MN) during a Wednesday night Trump campaign rally.

In response to Keith's question, Trump 2020 communications director Tim Murtaugh not only refused to disavow the chants, but then took the opportunity to attack the entire Democratic Party for being aligned with "socialism."

"The Squad, as they call themselves, are now the leaders of the Democrat Party," he replied. "Americans don’t like it when elected officials consistently disparage this country. All the Democrats are pushing socialist ideas that are terrible for America. They are all the same."
