A powerful form of clean energy already exists – and it is far more reliable than wind and solar

On 30 April, the Indian Point nuclear power plant 30 miles north of New York City was shut down. For decades the facility provided the overwhelming majority of the city’s carbon-free electricity as well as good union jobs for almost a thousand people. Federal regulators had deemed the plant perfectly safe.

New York’s governor, Andrew Cuomo, a key figure behind the move, said that the shuttering of Indian Point brought us “a big step closer to achieving our aggressive clean energy goals”. It’s hard to reconcile that optimism with the data that’s recently come out. The first full month without the plant has seen a 46% increase in the average carbon intensity of statewide electric generation compared to when Indian Point was fully operational. New York replaced clean energy from Indian Point with fossil fuel sources like natural gas.

It’s a nightmare we should have seen coming. In Germany, nuclear power formed around a third of the country’s power generation in 2000, when a Green party-spearheaded campaign managed to secure the gradual closure of plants, citing health and safety concerns. Last year, that share fell to 11%, with all remaining stations scheduled to close by next year. A recent paper found that the last two decades of phased nuclear closures led to an increase in CO2 emissions of 36.3 megatons a year - with the increased air pollution potentially killing 1,100 people annually.

Like New York, Germany coupled its transition away from nuclear power with a pledge to spend more aggressively on renewables. Yet the country’s first plant closures meant carbon emissions actually increased, as the production gap was immediately filled through the construction of new coal plants. Similarly, in New York the gap will be filled in part by the construction of three new gas plants. For the Germans, investment in renewables did eventually pay...
