What might the cleaner, greener houses and apartments of 2050 look like if they take advantage of new technologies? Berkeley Lab energy technology researchers gave a glimpse into what a home built in 2050 might look like.

Art Rosenfeld, a physicist and Berkeley Lab Distinguished Scientist Emeritus, transformed the fledgling field of energy efficiency from a research afterthought into a scientific discipline.

Berkeley Lab scientists discuss how advances in energy storage can help us prevent extreme weather-related blackouts, adopt more renewable energy, and build bigger, better, more environmentally responsible batteries.
