Heat pumps

A recent trip to East Asia prompted our correspondent to reframe his understanding of heat pumps, the crucial tool for cleaning up the heating and cooling of buildings.

Grid edge

An SEC filing suggests the federal Loan Programs Office is gearing up to help lower-income households access rooftop solar and batteries that can help the grid.

Fossil fuels

They can’t keep spending on pipelines, and alternative fuels can't scale. But electric heat and thermal networks could save utility business models and jobs.

Solarcycle just raised another $30 million to build more solar recycling factories. See what the recycling process looks like.

Fossil fuels

Starting in 2027, San Francisco Bay Area regulators will require appliances to have zero emissions of nitrogen oxides, a move that effectively bans gas.

Clean energy

Solar, wind and hydropower fluctuate seasonally. At some times of the year, they're now providing as much as a third of electricity to the U.S. grid.

This week, Los Angeles Cleantech Incubator launched its second impact fund, with a focus on supporting diverse entrepreneurs.

Solar

Allume Energy’s SolShare tech can divvy up solar output among apartment units however property owners choose, delivering more flexibility to an underserved market.

Plus, climatetech career moves at DOE, Rewiring America, Cypress Creek, GAF Energy, NYPA, Mission Strategies, Activate Capital and more.

The collapse of SVB, a key early funder of community solar, won't halt the sector's growth — but the ripple effects will likely impact all clean-energy development.

Nuclear

Billions over budget and years behind schedule, the expansion of the Vogtle nuclear power plant signals that conventional nuclear projects are a dying breed.

Watch reporter Julian Spector explain how heat pumps have gone big around the globe and are now set to take off in the U.S. thanks to federal incentives.

Fossil fuels

Amid the gas-stove hubbub, the health impacts of other gas appliances like furnaces, water heaters and dryers haven't gotten much attention. Here's a rundown.

Watch staff writer Alison Takemura share tips on how to make your electrified, energy-efficient dream home a reality.

Clean energy

Solar, wind, nuclear and grid batteries will account for nearly all power plant construction, with batteries beating gas for the first time.

Carbon capture

The Carbon Removal Alliance is all about practical and permanent solutions for capturing CO2 — shady offsets and short-term schemes need not apply.

Batteries

The conglomerate controls a 36,000-unit virtual power plant. Up next? Unleashing it to help the national grid decarbonize.

Clean industry

The Biden administration announced it will help fund projects to clean up the production of steel, cement, aluminum and other hard-to-decarbonize sectors.

Hydropower

Planned for White Pine County, Nevada by developer rPlus, it would be one of the first large-scale pumped-hydro projects built in the U.S. in decades.

Energy efficiency

In partnership with Sol Systems, the tech giant is using a slice of its clean-energy investments for repairs and efficiency upgrades in lower-income communities.

Electrification

The startup is one of many companies springing up across the U.S. to shepherd consumers through the complicated and multifaceted process of home electrification.

Electric vehicles

The state's ambitious timeline for cleaning up trucks will slash pollution in port communities, but some freight firms may not be able to afford the switch.

Grid edge

Shifted Energy is tapping water heaters in lower-income communities to create virtual power plants that help balance the grid, starting in Hawaii.

Food and farms

Advocates say revamping the 20-year-old federal Rural Energy for America Program could give cash-crunched small farms some much-needed breathing room.
