Bloomberg carries an opinion piece which highlights the need for nuclear power:
Nuclear accounts for almost 60 percent of emissions-free power in the U.S., and when plants shut down, utilities mostly turn to fossil fuels to fill the void. More than one-third of the country’s plants, representing 22 percent of total nuclear capacity, are either scheduled to close or at risk of closure within the next five to 10 years, said a new UCS study. This could lead to a 4 percent to 6 percent increase in carbon emissions from the power sector by 2035.
Nuclear power is expensive, and it’s under pressure from market forces – notably, the falling price of solar and wind power.
Then why not simply let it lose market share to those safe, clean fuels? Because wind and solar can’t immediately fill the gap. They still account for less than 8 percent of energy produced in the U.S. (nuclear is 20 percent). It’s crucial that their growth displaces coal and natural gas, not nuclear.
In principle, a carbon tax is the best way to keep nuclear power competitive.
As the voters of Washington state have again demonstrated, however, taxes on fuel remain prohibitively unpopular. (French President Emmanuel Macron has just made the same discovery.) Nonetheless, states can reward nuclear power’s climate advantage in other ways – by giving zero-emissions credits for nuclear power, as Illinois, New York and New Jersey have done, or by revising their energy portfolio standards to stop utilities’ switching from nuclear to fossil fuels.
If enough states take such measures, old plants could be kept running until the next generation of nuclear plants is ready. Building these might also require subsidy – for example, in the form of investment tax credits.
These and other options need to be on the table as the world wakes up to the role nuclear power must play in avoiding a climate catastrophe.
This highlights the need for an all of the above strategy for generating electricity. All fuel sources have pros and cons, but finding the right mix is essential for maintaining reliable and affordable energy.
