Current conditions: The parade of winter storms continues today across much of the U.S. • The Congo River is at its highest level in more than 60 years after intense rains • This weekend's NFL game between the Kansas City Chiefs and the Miami Dolphins could be the coldest game in franchise history.


1. IEA report shows renewables expansion gaining momentum

The International Energy Agency (IEA) is feeling optimistic about the green energy transition. In its new Renewables 2023 report, released today, the agency says the world added 50% more renewable capacity last year than in 2022. This kind of momentum could get us close to the COP28 goal of tripling global renewable energy capacity by 2030, but governments must do more to get us across the finish line, the IEA concluded.

Renewable capacity hit almost 510 gigawatts (GW) in 2023, with China seeing the most explosive growth, but the U.S., Europe, and Brazil also hit all-time highs. Solar was the real workhorse, accounting for 75% of the expansion. The report includes this quite astonishing statistic:“The world is on course to add more renewable capacity in the next five years than has been installed since the first commercial renewable energy power plant was built more than 100 years ago.”

The current growth rate puts the world on course to increase renewable capacity by two-and-a-half times by 2030, said IEA Executive Director Fatih Birol. He calls on governments to prioritize policy changes that speed up renewables development, and highlights the need for more financing in developing countries to help them with the energy transition. “Success in meeting the tripling goal will hinge on this,” Birol said.

2. Biden funnels $623 million into EV charging network buildout

The Biden administration has announced the recipients of infrastructure grants amounting to $623 million focused heavily on expanding the national electric vehicle charging network. The administration has a goal of installing at least 500,000 public chargers by 2030 – a Department of Energy report put the number at around 140,000 at the end of 2022, installed across 53,000 stations. Huge gaps in coverage remain across the country, fueling range anxiety among would-be EV buyers. The new grants are split between 22 states and Puerto Rico and will support 47 infrastructure projects, including 7,500 charging ports. About half of the money will go to “community” projects in urban and rural communities. The other half will go to “corridor” projects along roadways that are expected to “fill gaps in the core national charging and alternative-fueling network,” according to the U.S. Department of Transportation’s press release.

3. GOP presidential candidates pile on Biden for ‘green’ policies

It appears that Republicans have a new favorite boogeyman buzzword this election season, writes Heatmap’s Charu Sinha. The word? “Green.” It was on every Republican presidential hopeful’s lips on Wednesday, both at CNN’s debate in Iowa between Florida Governor Ron DeSantis and former UN Ambassador Nikki Haley, and at former President Donald Trump’s competing town hall on Fox News. DeSantis reiterated his promise to reverse President Biden’s clean energy policy, facetiously calling it the “Green New Deal.” Haley took her own stab at Biden’s “green subsidies” while answering a question about funding Ukraine and Israel. And for his part, Trump said Biden should “go into the energy business instead of this green new scam business that they’re in."

Sinha notes that “at no point during the fifth Republican presidential debate or Trump’s town hall was the Inflation Reduction Act mentioned by name.”

4. Bird flu found in mammals in Antarctica

Bird flu strain H5N1 has been transmitted to seals in Antarctica, scientists have confirmed, an alarming development that raises concerns about how easily the virus can spread among mammals. The virus, which has killed millions of birds across the world, was detected in elephant seals and fur seals on the sub-Antarctic island of South Georgia. Researchers believe migrating birds from South America brought the virus with them. Last week officials in Alaska confirmed a polar bear had died from the disease. “If a bird is weakened by avian influenza, or succumbs to it, polar bears aren’t fussy about what eat,” Andrew Derocher, a polar bear biologist at the University of Alberta, toldReuters. “If it’s dead and it’s edible they’ll probably eat it. There is a high likelihood of an interaction between climate change, avian influenza, bird mortality, and polar bears.”

5. Study: Snowpack worryingly low in parts of Northern Hemisphere

The Northern Hemisphere is seeing less snowpack due to human-caused climate change, according to a new study published in Nature. The researchers examined data from hundreds of river basins across the U.S. and Europe and found that about 20% of them saw a decline in snowpack – which is the total mass of snow that accumulates on the ground – over the last 40 years. “We see a pattern of snow change that is only consistent with human emissions,” Alex Gottlieb, a graduate student at Dartmouth College and lead author on the new study, toldThe Washington Post. The researchers also seem to have discovered a snow “cliff” – a tipping point temperature of 17 degrees Fahrenheit – at which snow loss accelerates very quickly. They say more than 2 billion people who rely on snow melt as a source of water are near the cliffedge.


The cost of charging an EV in the U.S. is roughly equivalent to a gasoline price of $1 to $2 per gallon, with the national average being $1.41 per eGallon, according toYale Climate Connections.

Nuclear Energy Is the One Thing Congress Can Agree On

Environmentalists, however, still aren’t sold on the ADVANCE Act.

While climate change policy is typically heavily polarized along party lines, nuclear energy policy is not. The ADVANCE Act, which would reform the nuclear regulatory policy to encourage the development of advanced nuclear reactors, passed the Senate today, by a vote of 88-2, preparing it for an almost certain presidential signature.

The bill has been floating around Congress for about a year and is the product of bipartisanship within the relevant committees, a notable departure from increasingly top-down legislating in Washington. The House of Representatives has its own nuclear regulatory bill, the Atomic Energy Advancement Act, which the House overwhelmingly voted for in February.

1. Lengthy heat wave threatens nearly 80 million Americans

About 77 million people are under some kind of heat advisory as a heat wave works its way across the Midwest and Northeast. In most of New England, the heat index is expected to reach or exceed 100 degrees Fahrenheit. What makes this heat wave especially dangerous is its “striking duration,” Jake Petr, the lead forecaster with National Weather Service Chicago, toldThe New York Times. Temperatures are projected to stay exceptionally high for several days before beginning to taper off only slightly over the weekend. According toThe Washington Post, temperatures could be up to 25 degrees higher than normal for this time of year. And forecasters expect it to be unseasonably hot across the country for at least the next three weeks. Below is a look at the NWS HeatRisk projections today (top) and Thursday (bottom). The darker the color, the warmer the temperature and the higher the health risks.

Crux Is Getting Some Powerful New Backers

The New York-based startup aims to create a market for clean energy tax credits.

One of the least-noticed changes in the Inflation Reduction Act may be one of the most important.

For years, the government has encouraged developers, power utilities, and other companies to build clean energy by offering tax credits. But those tax credits were difficult to transfer to other companies, meaning that complicated financial instruments had to be created to allow them to share in the wealth.
