Turbines Turning Profits

What’s Behind the World’s Biggest Climate Victory? Capitalism

Wind turbines dominate the landscape at the Avangrid Renewables’ Baffin Wind Power Project in Sarita, Texas.



The chief executive of the world’s largest private coal company sat before a group of U.S. lawmakers who wanted to know whether the fuel had a future. He didn’t hesitate. “Coal,” he said, “is the future.”

It was 2010. Coal supplied nearly half of America’s power, the executive testified, and was growing more than 1.5 times faster than oil, natural gas, nuclear and renewables combined. Global demand was on pace to rise 53% within two decades. And renewable energy? Not an option. “Wind and solar comprise just 1% of today’s U.S. energy mix,” Gregory Boyce, then the chief executive of Peabody Energy Corp., told the members of Congress. “It is unrealistic to suggest that renewables could replace conventional baseload fuels.”

Not quite. This April, for the first time ever, renewable energy supplied more power to America’s grid than coal—the clearest sign yet that solar and wind can now go head-to-head with fossil fuels. In two-thirds of the world, they’ve become the cheapest forms of power.

Solar and wind will power half the globe by 2050, based on BloombergNEF forecasts. By that time, coal and nuclear will have all but disappeared in the U.S., forced out by cheaper renewables and natural gas.

Solar and Wind Take Off as Coal Fades Away


The market triumph of renewable energy marks the biggest victory yet in the fight against global warming. Solar and wind are proliferating not because of moral do-gooders but because they’re now the most profitable part of the power business in most of the world. An industry that once relied on heavy subsidies and was propped up by government mandates is now increasingly standing on its own.

As a recent United Nations report put it: The renewable energy sector is “looking all grown up.”

In the effort to slow climate change, the energy sector matters. Electricity generation has traditionally been the world’s biggest source of greenhouse-gas emissions. In the U.S., for the first time since the 1970s, this is no longer the case. Since 2016, American power plants have given off less carbon dioxide than the nation’s transportation sector, where oil continues to dominate. The turnabout owes a lot to cheap and cleaner-burning natural gas, but wind and solar farms are playing an increasingly important role.

Solar, wind and hydropower resources combined generate more than a quarter of the world’s electricity. In China and India that share will surpass 60% by 2050, BNEF estimates show, and Europe will top 90%.

Renewable energy won’t save the world on its own. Power generation accounts for about a quarter of greenhouse-gas emissions being released into the atmosphere in the U.S. The rest comes mainly from transportation, manufacturing, agriculture and heating and cooling homes and businesses.

Those sectors will need to match the sweeping technological advances and more efficient manufacturing that have slashed the costs of solar and wind power. Battery prices have fallen 84% in less than a decade. Cheaper parts are what have made solar and wind more economical to build than coal and gas plants across two-thirds of the world. Five years ago, by BNEF’s count, this was virtually nowhere.

In the U.S., natural gas remains king of the power mix, accounting for about 40% of the nation’s electricity. But renewable energy’s share is quickly climbing, reaching 25% earlier this year.

In a sign of where things are headed, solar installers and wind technicians are the two fastest-growing professions in the U.S. Solar now employs more people than any other power source. Wind supports almost as many jobs as gas.

Today, gas is increasingly coming under attack. Berkeley, California, became the first city in America to ban gas in new homes and businesses earlier this year. Lawmakers from Seattle to San Jose are weighing bans. The British government has proposed a similar prohibition.

In developing parts of the world, coal still dominates. China is home to the largest capacity of hydro, wind and solar power—and it remains the world’s biggest consumer of coal. Pakistan’s dream of generating 60% of its power from clean energy sources is still decades away. In Indonesia, coal plants are so cheap to run that the Southeast Asian nation is projected to nearly double its coal generation in the next 25 years.

The growing divide underscores a global dilemma: Wealthy nations can afford to turn their backs on coal, but it remains an easy fallback in countries where electricity is scarce, unreliable, or unaffordable.
