Reporter's Notes: Building an Artificial Leaf

Reporter's Notes: Building an Artificial Leaf

When I began this story, it seemed pretty simple. I'd heard that scientists at Lawrence Berkeley National Lab were working to mimic photosynthesis and create a man-made version of the process that could supply us with renewable energy.

Those Intermittent Renewables – Part 2

"We believe energy storage is the next big thing," says Craig Horne, CEO of EnerVault, a Sunnyvale startup. His company is developing a battery that could help solve a renewable energy problem (check out our previous post): how to keep electricity flowing when we need it, even as more of it comes from sources we can't control. Horne was a panelist at a UC Berkeley-Stanford sponsored CleanTech Conference about energy storage held last week at Berkeley's Lawrence Hall of Science.

Reporter's Notes: Smart Grid at Home

Reporter's Notes: Smart Grid at Home

I've never paid much attention to my electric meter. For most of us, it's just that box on the side of the house with a small white disk spinning inside, keeping track of our energy use. But over the next three years, all the meters for PG&E customers will be getting a major upgrade to a new, digital SmartMeter.
