This clever system taps basement temps to cool your home, and now it can heat, too

Cool Down

New York-based Cool Down makes a thermal transfer system that moves naturally cool air from your basement into your living space while sending excess heat back down below to cool homes more efficiently. By dispersing that heat into the ground, Cool Down helps keep homes comfortable during hot summer months and cuts electricity bills in the process.

In a first, renewables generate more power than coal globally

renewables coal global solar

Solar and wind power aren’t just keeping up with global electricity demand anymore – they’re pulling ahead. According to a new analysis from energy think tank Ember, solar and wind combined outpaced global electricity demand growth in the first half of 2025. That shift led to a drop in both coal and gas generation compared to the same period last year. For the first time ever, renewables generated more power than coal globally.

The era of cheap Chinese solar + storage is ending – here’s why

Trinasolar Chinese solar storage

Solar and storage prices are about to rise after a year and a half of record lows, according to new data from Wood Mackenzie. Equipment procurement costs for solar and energy storage will jump around 9% starting in Q4 2025, marking the end of the bargain pricing developers have enjoyed for the last 18 months. That’s because China is changing the rules.

FERC: Solar + wind made up 90% of new US power generating capacity to July 2025

FERC July 2025

Solar and wind accounted for 90% of new US electrical generating capacity added in the first seven months of 2025, according to data just released by the Federal Energy Regulatory Commission (FERC). In July, solar alone provided 96% of new capacity, making it the 23rd consecutive month solar has held the lead among all energy sources.

EVs and batteries fuel the US VPP boom, hitting 37.5 GW in 2025

virtual power plants US VPPs

The US virtual power plant (VPP) market is growing fast, with 37.5 gigawatts of behind-the-meter flexible capacity now online, according to a new Wood Mackenzie report. VPPs connect small energy systems and smart devices into a single network managed by an energy company or utility. That can include residential solar panels, battery storage, EVs, and smart thermostats. When the grid needs help during peak demand or emergencies, they can be tapped – and you get paid for participating.

Solar + nuclear to surge in Middle East as electricity demand soars – IEA

Middle East electricity

Electricity demand is skyrocketing across the Middle East and North Africa, and it’s being driven by two big factors: cooling homes and businesses in extreme heat, and making seawater drinkable through desalination. A new report from the International Energy Agency (IEA) shows just how dramatic the surge is. Electricity use in the region has tripled since 2000, and it’s expected to jump another 50% by 2035. That’s like adding the current combined electricity demand of Germany and Spain.

China’s surge pushes global wind toward fastest growth ever

global wind growth

The global wind industry is going to hit some unprecedented growth milestones, according to Wood Mackenzie’s Global Wind Power Market Outlook for Q3 2025. The world is on track to add its second terawatt of wind capacity by 2030. To put that in perspective, it took 23 years to install the first terawatt, which was reached in 2023. The second will come in just seven.

China’s wind + solar revolution is shaking up the global energy game

China wind solar

China’s clean energy surge is starting to transform the world’s energy systems, according to Ember’s “China Energy Transition Review 2025.” The report shows that China’s massive investments in solar, wind, storage, and electrification are cutting fossil fuel use at home while sending clean tech around the globe.

The US solar industry put nearly 18 gigawatts (GW) of new capacity on the grid in the first half of 2025. Even as the Trump administration rolled out anti-clean energy policies, solar and storage still made up 82% of all new power added to the grid in the first six months of the year. But the growth picture isn’t as sunny as it looks, according to the SEIA.

H1 2025: China installs more solar than rest of the world combined

China solar 2025

Global solar installations are breaking records again in 2025. In H1 2025, the world added 380 gigawatts (GW) of new solar capacity – a staggering 64% jump compared to the same period in 2024, when 232 GW came online. China was responsible for installing a massive 256 GW of that solar capacity.

The first US floating solar tracker pilot kicks off in Colorado

US floating solar tracker

Colorado is about to see the US’s first floating solar tracker project hit the water.

Noria Energy has started construction on Aurea Solar, a 50 kW floating solar pilot in Golden, Colorado, that will use trackers. The project will power local water utility operations at the Fairmount Reservoir, which is owned and operated by the Consolidated Mutual Water Company (CMWC).

EIA: Solar and wind leave coal in the dust with record 2025 output

US largest solar storage

A new review of US Energy Information Administration (EIA) data by the SUN DAY Campaign reveals that solar delivered almost 9% of US electricity in the first half of 2025. Wind and solar combined produced just over one-fifth of the country’s electricity, while renewables as a whole hit nearly 28%.
