Current conditions: Shanghai, still recovering from the strongest storm to hit the city in 75 years, is bracing for Typhoon Pulasan • Extreme flooding in the north of Italy has forced some 1,000 people to evacuate • It’s looking unlikely that this month will break last year’s record for warmest September ever.
THE TOP FIVE
1. Ember: 2024 will be another record year for solar
The explosive growth in solar power shows no signs of stopping this year. New analysis from energy think tank Ember forecasts the world is on track to add 593 gigawatts of solar power in 2024, nearly 30% more than last year’s installations and nearly 200 GW more than the International Energy Agency predicted at the start of the year. The report underscores how a handful of countries are responsible for most of the world’s new solar capacity. China leads, followed by the U.S., India, Germany, and Brazil. These five countries are on track to account for 75% of new global installations in 2024. And they are sustaining their growth year after year.

Here’s the most important takeaway from the Ember report: “This now puts ambitious climate pledges within reach.” It’s very possible – and indeed likely – that the world will triple solar capacity by 2030. In this scenario, solar power would generate a quarter of the world’s electricity. “Countries need to plan ahead to make the most of the high levels of solar capacity being built today and ensure the continued build-out of capacity in the coming years,” the report says.
2. Fed interest rate cut could boost investment in renewable projects
The Federal Reserve announced yesterday that it would reduce the benchmark federal funds rate by half a percentage point, from just over 5% to just below. What does this mean for renewable energy? Well, it just became a much more enticing investment, wrote Heatmap’s Matthew Zeitlin. High interest rates have an outsize effect on renewable energy projects, because the cost of building and operating a renewable energy generator like a wind farm is highly concentrated in its construction. Wood Mackenzie estimates that a 2% increase in interest rates pushes up the cost of energy produced by a renewables project by around 20%, compared to just over 10% for conventional power plants. “As rates fall, projects become increasingly financially viable,” said Advait Arun, senior associate of energy finance at the Center for Public Enterprise and Heatmap contributor.
3. EU official warns ‘climate breakdown’ is becoming the norm
The European Union’s head office has warned that the extreme weather devastating parts of the continent are proof that “climate breakdown” is “fast becoming the norm,” The Associated Press reported. Parts of Europe are experiencing some of the worst flooding in at least two decades, while Portugal has declared a “state of calamity” as enormous wildfires rage out of control and threaten the homes of more than 200,000 people. “We face a Europe that is simultaneously flooding and burning. These extreme weather events ... are now an almost annual occurrence,” said EU Crisis Management Commissioner Janez Lenarcic. “The global reality of the climate breakdown has moved into the everyday lives of Europeans.” Europe is the fastest warming continent on Earth.
4. AI weather startup Brightband emerges from stealth
Today the startup Brightband emerged from stealth with $10 million in Series A funding and a unique plan to commercialize generative AI weather modeling. Instead of trying to go up against Weather.com, Brightband is tailoring models to specific industries such as insurance, finance, agriculture, energy, and transportation. The round was led by Prelude Ventures. AI models like Brightband’s are trained on decades worth of past weather data, and when fed a snapshot of current conditions, can predict what will come next, much like ChatGPT does with text. Brightband’s CEO Julian Green told Heatmap’s Katie Brigham that customizing forecasts for particular industries will also be as simple as querying a large language model. A wind farm operator could, for example, “just take an attached file of historical wind energy production, and throw it in there and say, hey, tell me what the wind energy is going to be like next week.” Brightband says it hopes to publish a paper by year’s end with an open-source version of its forecast model, alongside evaluation tools to assess its performance.
5. Truck drivers seem to approve of Tesla Semi
Truck drivers seem to really like Tesla’s Semi electric truck. PepsiCo is Tesla’s first customer for the trucks, and has 89 of them deployed across various fleets. Speaking at the IAA Transportation event, PepsiCo’s electrification program manager Dejan Antunović said some veteran drivers are reporting that they never want to go back to driving diesel after having handled the Tesla Semi. “Based on its history of delivering efficient electric vehicles in volume profitably, I think Tesla is the one to make commercial electric trucks happen at scale,” wrote Electrek’s Fred Lambert.
THE KICKER
Researchers were pleasantly surprised to discover that 90% of young corals that were bred using in vitro fertilization and deposited in reefs across the Caribbean survived last year’s marine heatwave.
