A powerful new solar cell produces both hydrogen fuel and electrical power

“In a field that’s essentially water-bending meets renewable energy, researchers successfully harnessed photosynthesis to split water to produce hydrogen fuel. Splitting H2O at its molecular level is something scientists have been doing for over 200 years, and could hold the tantalizing key to an emission-free hydrogen economy — if only it could be scaled up.…

Powering Forward: POUs are critical to California’s energy efficency progress

Publicly owned utilities (POUs) in California play a critical role in advancing energy efficiency. The 38 POUs that report electricity-savings data provide power to nearly one-quarter of the state’s population. Our analysis shows that over the past 12 years, POU energy efficiency programs—which help people use less energy while getting the same or better services—have…

A geographically resolved method to estimate levelized power plant costs with environmental externalities

In this analysis we developed and applied a geographically-resolved method to calculate the Levelized Cost of Electricity (LCOE) of new power plants on a county-by-county basis while including estimates of some environmental externalities. We calculated the LCOE for each county of the contiguous United States for 12 power plant technologies. The minimum LCOE option for…

Increased performance and lifetime of lithium batteries in renewable energy facilities

“”Renewable technology has in recent years overcome various technological pitfalls, and after achieving a competitive price with respect to conventional energy sources, the main challenge today is to manage its variable generation caused by fluctuations in solar radiation or wind. That is why the solution is to store the electricity produced in lithium batteries.”” Click…

The electricity price isn’t right

“Setting prices too low is a climate problem, but so is setting prices too high. We didn’t hear much about electricity pricing at last week’s Global Climate Action Summit in San Francisco. But when it comes to sub-national entities addressing climate change (as well as local pollution), electricity prices are one of the most powerful…
