Shasta Lake is the largest reservoir in California, and government officials are completing plans to make it even larger by raising the height of the dam. But the expansion has sparked intense debates among local residents, Central Valley farmers, environmentalists, tribal groups and developers.
Valero wants to start using trains to bring crude oil to its Bay Area refinery. But the project is raising concerns about congestion, safety and air pollution in the East Bay city of Benicia – and the connection it may have to Canada’s controversial tar sands.
Californians continue to favor strong, immediate action on climate, but not at any cost. And most of us still drive to work solo.
When you're cooking dinner, the air inside your kitchen can sometimes be just as harmful as smog. Range hoods are designed to capture cooking fumes, but even some expensive models aren’t very effective. Researchers are trying to fix that.
Spent reactor fuel and other high-level radioactive wastes may be better off in soft rocks than hard ones.
After controversy over a threatened species delayed several large solar projects, state officials are trying to broker an agreement between conservation groups and solar companies on a path forward for renewable energy.
The Panoche Valley Solar Farm cleared a hurdle this week. Environmental groups sued to stop the solar project, located near Hollister, but the suit was rejected.
Mounting research questions the safety and effectiveness of flame retardants used in consumer products. The chemicals are also used in the foam plastic insulation that improves energy efficiency in buildings. But a measure that just passed a Senate committee this week could pave the way for fire-safe, energy-efficient buildings without causing harm.
President Obama is introducing a plan to cut greenhouse gas emissions from power plants and support more renewable energy development.
The San Onofre nuclear plant has not operated since January 2012, when a radioactive leak was discovered in one of its generators. The permanent closure could put pressure on California's electrical grid in the long-term. The California Independent System Operator, which manages the grid, does not expect statewide problems with power supply this summer.
This week, PG&E unveiled California’s largest battery project, now storing electrons in San Jose. The project is a pilot for energy storage technology, as electric utilities look for ways to balance increasing amounts of solar and wind energy on the grid.
Solar panels have sprouted up all over the sunny spots of California, but for industrial scale projects, there's no beating desert country -- if the price is right. Developers are cheering a decision by Riverside County officials on Tuesday to slash fees on new projects. Riverside could set a new standard for how local communities do business with big solar. »
As increasing numbers of Californians generate their own electricity, they rely less on electric utilities. That’s raising major questions about the future of California’s utilities.
Lighter than an SUV and covered with more than 12,000 solar cells, Solar Impulse, the world's first solar plane that can fly day and night without recharging, launched from Moffett Field this morning in a cross country voyage. The $150million project initiated by co-pilots Bertrand Piccard and Andres Borschberg will ...
After missing a September 20, 2012 deadline to ignite a nuclear fusion reaction -- essentially a tiny sun -- in a laboratory, scientists at Lawrence Livermore National Lab are making some changes. The National Ignition Facility (NIF) was designed to provide a means to study the effectiveness of ...
Photo Wikimedia Commons This new solar panel really is green. Instead of using semiconducting silicon, proteins from plants transform light into electricity. Physicist Andreas Mershin, at Massachusetts Institute for Technology, and his colleagues say they’ve simplified the production of plant-based solar cells so that any lab ...
Tesla's new Model X. Photo: Wired Tesla and Fisker are not exactly producing electric cars for the 99 percent. Still, these two luxury green automakers are closely watched because both companies have received hundreds of millions in federal loans to help jump start ...
