Across the United States, hundreds of microgrids provide power independently of regional electric grids. These facilities, which often include solar panels backed by battery energy storage, can help keep the power on locally while easing stress on the larger grid when demand is high or outages strike. A recent feature in The New York Times spotlighted microgrids in real estate development,...

Researchers are hard at work on ways to make buildings more energy-efficient and user-friendly as part of net zero carbon emissions energy systems. That means things like windows and walls that take advantage of nature to heat and cool, better batteries to store and deliver energy when needed, and systems that can adapt to changes from the electrical grid. What would it look like to combine all of...

Wildfires have become increasingly frequent due to climate change, with record occurrences in areas not historically prone to them. In California, wildfires and regional power shutoffs have cost billions and taken lives. For some 46 million Americans living next to forests — at what scientists call the “wildland-urban interface” (WUI) — the risks of wildfire can be especially acute....

When it comes to energy efficiency in California buildings, windows are a weak link. About half of the state’s homes still have inadequate, single-pane windows. A significant portion of these homes are in communities throughout the state that may have more vulnerable populations. Windows pose a key opportunity both to reduce carbon emissions from California’s buildings and to boost energy...

Levels of planet-warming carbon dioxide in the air continue to rise. Cutting emissions by moving away from fossil fuels is a priority – but so is removing carbon that’s already been emitted. Of the many emerging technologies on the table, which ones will be most effective, and where? What about costs? What kinds of investments will have the most impact? Scientists at the Department of...

About 12% of the total global energy demand comes from heating and cooling homes and businesses. A new study suggests that using underground water to maintain comfortable temperatures could reduce consumption of natural gas and electricity in this sector by 40% in the United States. The approach, called aquifer thermal energy storage (ATES), could also help prevent blackouts caused by high power...

Limiting global warming to 1.5 degrees Celsius above pre-industrial levels will require severely cutting greenhouse gas emissions by nearly 50% by 2030. Doing so calls for the immediate, large-scale adoption of energy efficiency, renewable energy, electrified transportation, high-performance batteries, low-carbon grids, and carbon capture and storage technologies across all sectors globally.
