Here’s a dirty secret: The North American Electric Reliability Corp. projects that more homes will have blackouts over the next decade. That’s why President Trump’s energy executive orders have arrived not a moment too soon.

When blackouts occur, people can’t cook, use lights and heat, or recharge computers or cellphones. For people in frail health, interruptions can be fatal, especially in winter. Americans learned from winter storm Uri in Texas in 2021, which caused 246 deaths, that lights must stay on and houses must be kept warm, or people die.

The grid’s weakness stems from surging energy demand and planned closures of numerous power plants. Energy demand is skyrocketing as companies build more data centers and artificial intelligence applications.

At the same time, Inflation Reduction Act tax credits skew investment toward intermittent wind and solar power. But applications for new baseload power, which operates around the clock—coal, natural gas and nuclear—are lagging.

On his first day in office, Mr. Trump called for reversing President Biden’s anti-energy agenda with multiple executive orders.

Mr. Trump withdrew America from the Paris Agreement, which required costly, unreliable wind and solar power. This will save trillions of dollars, decrease electricity and transportation costs, and allow people worldwide to develop their own natural resources, including fossil fuel resources.

The president called for increased development of rare earth minerals, elimination of the electric vehicle mandate and development of energy sources readily abundant on U.S. soil: coal and natural gas. Americans can choose which cars and appliances to buy, abandoning electrification incentives.

The president temporarily halted the leasing and permitting of all federal wind energy, which consistently overpromises and underdelivers at the expense of U.S. taxpayers.

Finally, the president ended the Biden administration’s restrictions on energy resource development in Alaska.

These are wise decisions. The government must take immediate action if America wants to avoid the North American Electric Reliability Corp.’s projected blackouts.

The organization’s report states, “Less overall capacity … is being added to the system than what was projected and needed to meet future demand.” It predicts that 10 of the 20 regional assessment areas that divide the North American power grid are at elevated risk. Blackouts may occur in extreme weather conditions within the next four years. This is a clear warning, and Americans should be concerned.

The North American Electric Reliability Corp. is particularly concerned about the stability of the Midcontinent Independent System Operator, which operates the power grid in portions of 15 states in the Midwest and South. The report warns of energy shortfalls even at normal peak conditions. More than half the power grid is anticipated to be at elevated risk in the next four years.

Energy droughts are more likely during high-demand times, including during extreme weather such as a winter storm or a polar vortex. Electricity demand soars, but renewable energy is dependent on the sun shining and the wind blowing, and these sources are not reliable.

Mr. Trump’s changes to energy policy will help reverse the North American Electric Reliability Corp.’s disturbing forecast. By prioritizing the development of readily abundant energy sources on U.S. soil, halting federal wind energy, and unleashing Alaska’s energy resource development, he will reduce incentives for unreliable wind and solar and raise incentives for coal and natural gas power plants. These executive actions will help stabilize the power grid and reduce the likelihood of its failure.

Biden-era regulations mandated electric cars, stoves and water heaters and required power plants to close if they could not bury 95% of their carbon emissions. The combination of artificially induced electricity demand and the required closures of power plants would have caused blackouts and deaths. Let us hope this disaster has been permanently averted.

Americans depend on electricity. People want to be sure of lights and climate control when the next winter storm or heat wave comes. America has plenty of power. All we have to do is use it.
