Low-Carbon Sources Provided 41% of the World’s Power Last Year

Current conditions: Europe just experienced its warmest March since record-keeping began 47 years ago • It’s 105 degrees Fahrenheit in India’s capital Delhi where heat warnings are in effect • The risk of severe flooding remains high across much of the Mississippi and Ohio Valleys.

THE TOP FIVE

1. Estimated losses from recent severe U.S. storms top $80 billion

The severe weather outbreak that has brought tornadoes, extreme rainfall, hail, and flash flooding to states across the central U.S. over the past week has already caused between $80 billion and $90 billion in damages and economic losses, according to a preliminary estimate from AccuWeather. The true toll is likely to be costlier because some areas have yet to report their damages, and the flooding is ongoing. “A rare atmospheric river continually resupplying a firehose of deep tropical moisture into the central U.S., combined with a series of storms traversing the same area in rapid succession, created a ‘perfect storm’ for catastrophic flooding and devastating tornadoes,” said AccuWeather’s chief meteorologist Jonathan Porter. The estimate takes into account damages to buildings and infrastructure, as well as secondary effects like supply chain and shipping disruptions, extended power outages, and travel delays. So far 23 people are known to have died in the storms. “This is the third preliminary estimate for total damage and economic loss that AccuWeather experts have issued so far this year,” the outlet noted in a release, “outpacing the frequency of major, costly weather disasters since AccuWeather began issuing estimates in 2017.”

2. Low-carbon sources provided 41% of world’s power last year

Low-emission energy sources accounted for 41% of global electricity generation in 2024, up from 39.4% in 2023, according to energy think tank Ember’s annual Global Electricity Review. That includes renewables as well as nuclear. If nuclear is left out of the equation, renewables alone made up 32% of power generation last year. Overall, renewables added a record 858 terawatt hours, nearly 50% more than the previous record set in 2022. Hydro was the largest source of low-carbon power, followed by nuclear. But wind and solar combined overtook hydro last year, while nuclear’s share of the energy mix reached a 45-year low. More solar capacity was installed in 2024 than in any other single year.

The report notes that demand for electricity rose thanks to heat waves and air conditioning use. This resulted in a slight, 1.4% annual increase in fossil-fuel power generation and pushed power-sector emissions to a new all-time high of 14.5 billion metric tons. “Clean electricity generation met 96% of the demand growth not caused by hotter temperatures,” the report said.

3. What Trump’s tariffs mean for solar imports

President Trump’s new tariffs will have a “limited” effect on the amount of solar components the U.S. imports from Asia because the U.S. already imposes tariffs on these products, according to a report from research firm BMI. That said, the U.S. still relies heavily on imported solar cells, and the new fees are likely to raise costs for domestic manufacturers and developers, which will ultimately be passed on to buyers and could slow solar growth. “Since the U.S.’s manufacturing capacity is insufficient to meet demand for solar, wind, and grid components, we do expect that costs will increase for developers due to the tariffs which will now be imposed upon these components,” BMI wrote.

4. U.K. eases 2030 EV targets, citing tariffs

In other tariff news, the British government is adjusting its 2030 target of ending the sale of new internal combustion engine cars to ease some of the pain from President Trump’s new 25% auto tariffs. Under the U.K.’s new EV mandate, carmakers will be able to sell new hybrids through 2035 (whereas the previous version of the rules banned them by 2030), and gas and diesel vans can also be sold through 2035. The changes also carve out exemptions for luxury supercar brands like McLaren and Aston Martin, which will be allowed to keep selling new ICE vehicles beyond 2030 because, the government says, they produce so few. The goal is to “help ease the transition and give industry more time to prepare.” British Transport Secretary Heidi Alexander insisted the changes have been “carefully calibrated” and their impact on carbon emissions is “negligible.” As The New York Times noted, the U.S. is the largest single-country export market for British cars.

5. EPA approves Occidental’s Texas CO2 injection well

The Environmental Protection Agency has approved Occidental Petroleum’s application to capture and sequester carbon dioxide at its direct air capture facility in Texas, and issued permits that will allow the company to drill and inject the gas more than one mile underground. The Stratos DAC plant is being developed by Occidental subsidiary 1PointFive. As Heatmap’s Katie Brigham has reported, Stratos is designed to remove up to 500,000 metric tons of CO2 annually and set to come online later this year. Its success (or failure) could shape the future of DAC investment at a time when the Trump administration is hollowing out the Department of Energy’s nascent Carbon Dioxide Removal team and casting doubt over the future of the DOE’s $3.5 billion Regional Direct Air Capture Hubs program. While Stratos is not a part of the hubs program, it will use the same technology as Occidental’s South Texas DAC hub.
