This number of vulnerable coal plants in the United States will increase to 86% by 2025 as solar and wind costs continue to decline.
The study shows that the operation of existing coal-fired power plants is always more expensive than the construction of clean energy alternatives.
"US coal-fired power plants are more dangerous than ever," said Mike O & # 39; Boyle, director of energy innovation policy at CNN Business. "Almost three-quarters of US coal-fired power plants are already" zombie coal "or the walking dead."
This is despite the promise of President Donald Trump to revive the besieged coal industry. Trump declared the end of the "war on coal" and broke regulations that restricted the emissions of coal-fired power plants.
"The Trump government's efforts to reduce environmental regulations are too little, too late to save coal," said O Boyle.
Rust Belt Coal-fired Power Plants Under Siege
The Energy Innovation Report found that by 2018, 211 gigawatts of existing US coal capacity – or 74% of the US fleet – were endangered by local wind or solar power, which could be cheaper as well Let the electricity run out.
North Carolina, Florida, Georgia, and Texas are the US states that have the largest number of coal-fired power plants vulnerable to local solar and wind energy. Energy Innovation defines locally as within 35 miles.
By 2025, it is expected that high levels of coal capacity will be available under pressure from renewable energy in midwestern Indiana, Michigan, Ohio, and Wisconsin.
Of course, just because it is economically feasible to shut down a coal-fired power plant and replace it with wind or solar does not mean that it will happen immediately. Government regulators must sign such decisions. And many power plants decide to pass on the additional costs to the customers.
In addition, coal remains an important employer in parts of Appalachia, and any closure can damage the local economy.
Coal was the long-time king of the energy industry before being exposed to fierce natural gas competition over the past decade. Natural gas is not only cleaner than fossil fuel, but abundant in the United States thanks to the shale revolution. Natural gas first exceeded coal in 2016 as America's leading power source.
The share of total power generation from coal-fired power plants has now fallen from 48% in 2008 to 28% in the last year, according to government statistics.
And the rise of renewables means that the economy has moved against coal again. Thanks to high levels of clean energy investment, solar prices have fallen by 90% since 2009 and are expected to continue to decline, according to Energy Innovation.
Large scale solar power alone is expected to increase by 10% in 2019 alone, while wind power is expected to be ahead of hydropower for the first time, according to the EIA.
"Coals biggest threat is now economy, not regulations," said O Boyle.

Another challenge for coal: US households and businesses are demanding more and more clean energy as they worry about climate change.
Households and companies install their own solar modules. According to the EIA, solar electricity generation in small areas is expected to grow by 44% over the next two years.
Pressured by voters, US states are setting ambitious targets for green energy – and they are portraying them as job creators.

California and Hawaii have recently achieved 100% clean energy targets.
Some utilities are moving quickly to adapt to this new environment.
