Southern California Edison is leading the way as utilities become the solar industry's largest customers, according to a report Wednesday by the Solar Electric Power Association, whose members include solar tech companies and more than 300 utilities.
The utility is ahead of its counterparts in both overall solar energy capacity per megawatt and per customer, the study found (PDF). Further north, Pacific Gas & Electric is in front in terms of overall solar capacity and megawatts per customer.
The nonprofit solar association compiled the rankings from data collected from 50 utilities this spring. It projected growth in U.S. … Read more
SANTA CLARA, Calif.--To cut greenhouse gas emissions, the United States has to invest equally as much in energy efficiency as in renewable energy technologies, and set a price on carbon dioxide emissions.
In a keynote speech, Rosenfeld--widely recognized for his contribution to California's aggressive energy-efficiency policies--cited a McKinsey report showing that the potential for greenhouse gas abatement in the U.S. between now and 2030 is evenly divided between investments in energy efficiency and renewable … Read more
If you are a San Francisco resident considering solar panels, now is the time for action, says Lyndon Rive, CEO of SolarCity, a start-up that leases panels to homeowners.
Since the city solar-incentive program came into effect in July, it has become financially viable for even small energy consumers to install solar-power systems.
The San Francisco incentive covers between $3,000 to $6,000 for homeowners to install solar panels, as well as $10,000 for businesses and nonprofits, and $30,000 for nonprofit affordable housing. The program runs for a decade.
This initiative, together with a state rebate program … Read more

In his speech in Constitution Hall this week, former Vice President and renewable energy investor Al Gore extolled a stretch goal challenging America to achieve 100% renewable power within 10 years.
The quote: "Today I challenge our nation to commit to producing 100 percent of our electricity from renewable energy and truly clean carbon-free sources within 10 years." And my favorite part: "When President John F. Kennedy challenged our nation to land a man on the moon and bring him back safely in 10 years, many people doubted we could accomplish that goal. But 8 years and … Read more
As in years past, fuel cell-powered vehicles are the technology of the future, according to a report published on Thursday by the U.S. National Academies.
Despite a great deal of technical progress, the study concludes that fuel cell vehicles will only make a significant dent in oil consumption and greenhouse gas emissions with decades of coordinated government policies and commitment from industry.
The primary barriers to adoption are high costs and the absence of an infrastructure to distribute hydrogen, the report said, which was commissioned by Congress and sponsored by the Department of Energy.
Fuel cell vehicles use hydrogen … Read more
The U.S. Environmental Protection Agency said on Friday that Congress, not the EPA, should regulate greenhouse gases.
EPA Administrator Stephen L. Johnson hosted a conference call with reporters on Friday where he said that existing law, the Clean Air Act, is "ill-suited" to addressing greenhouse gas emissions.
Instead, Johnson said that Congress should draft legislation to address climate change.
"It's really at the feet of the Congress to come up with good legislation that cuts through what will likely be decades of litigation and regulation," he said on the call.
Oil mogul and corporate raider T. Boone Pickens launched an energy plan and social-networking campaign on Tuesday that calls for replacing Middle Eastern oil with Midwestern wind.
The so-called Pickens Plan would exploit the country's "wind corridor" from the Canadian border to West Texas to produce 20 percent of the country's electricity.
Transmission lines would be built to transport the power to places in the U.S. where the demand is. The natural gas, now used to fuel power plants, would instead be used as a transportation fuel, which burns cleaner than gasoline and is domestic. … Read more
