100% Renewable Energy Using Building Science
In the Journal of Renewable and Sustainable Energy, researchers from the U.S. Department of Energy National Renewable Energy Laboratory describe results from a techno-economic analysis aimed at identifying pathways to 100% renewable power systems. By analyzing readily available supply and demand strategies within specific U.S. regions, the team found a combination of resource diversification, excess generation, building efficiency, and demand flexibility improvements could reduce or even eliminate the need for long-duration energy storage in some regions.

How Managing Building Energy Demand Can Aid the Clean Energy Transition
A comprehensive new study led by researchers from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) quantifies what can be done to make buildings more energy efficient and flexible in granular detail by both time (including time of day and year) and space (looking at regions across the U.S.). The research team found that maximizing the deployment of building demand management technologies could avoid the need for up to one-third of coal- or gas-fired power generation.
Exploring the Electrochemistry of Water-Based Batteries
Researchers at Stony Brook University (SBU) and the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have identified the primary reaction mechanism that occurs in a rechargeable, water-based battery made from zinc and manganese oxide. The findings, published in Energy and Environmental Science, provide new insight for developing grid-scale energy storage.
