Islands can be excellent places to promote clean energy. Because they are typically disconnected from both mainland grid infrastructure and sources of fossil fuels, it is easier for alternative sources of energy to gain a foothold. In fact, the cost of importing coal or oil to fuel power plants or vehicles can make fossil fuels vastly more... Hawaii, utility offer $10,000 electric-car rebates; hope for carbon-free transport

California continues to lead the United States, and in some ways the world, in efforts to reduce and eliminate harmful emissions from road vehicles. Following the lead of Governor Jerry Brown, the state legislature and regulatory agencies have set aggressive goals to reduce emission of climate-change gases, primarily carbon dioxide. That will be... 
During negotiations for the Paris Climate Treaty signed last fall, a major concern among critics was whether the carbon emissions of China's sprawling and inefficient energy sector could be reined in. With China, the U.S., and dozens of other countries signing the agreement, the world's most populous country committed itself to decarbonizing its... 
For electric utilities eager to hang onto their existing coal-fired power plants, carbon-capture technology must offer an exciting chance at salvation. As the name says, carbon capture retains and stores the emissions produced by coal power plants in particular, in theory mitigating some of their environmental impact. Power plants equipped with... 
While renewable-energy use has grown substantially over the last few years, the regulatory environment remains volatile. Some states have worked hard to stimulate renewable energy, supporting infrastructure projects and offering incentives to consumers who install home solar arrays. But others have tried to restrict renewable energy, often at the... 
The news on the renewable energy front continues to be good, with the costs of wind and solar generation falling steadily. By some measures, large-scale renewable energy is now cost-competitive (or close) with the most efficient natural-gas electric plants. Moreover, the amounts of clean generating capacity installed continue to rise, both in... 
In certain states, electric utilities are getting into the business of installing and operating electric-car charging infrastructure. They may build public charging stations, or work with other entities that operate them, but that's usually as far as their efforts to promote electric cars go. But one California utility is now taking direct action... ![Electric Avenue charging stations in Portland, Oregon [photo: Portland General Electric]](http://images.hgmsites.net/tmb/electric-avenue-charging-stations-in-portland-oregon-photo-portland-general-electric_100532762_t.gif)
It's clear that after several years of electric-car sales, electric utilities see a role to be played in providing the infrastructure to make them practical. Two weeks ago, California utility PG&E received approved to install 7,500 public charging stations for plug-in vehicles. Now, Oregon's two largest utility companies have filed plans to... 
Improving fuel efficiency doesn't always require creating a new vehicle. XL Hybrids markets modifications that allows fleet buyers to "upfit" their vehicles into hybrids. So far, the company's efforts have focused on hybrid powertrains for vans, box trucks, and shuttle buses. DON'T MISS: Ford Transit Van Gets Add-In Hybrid Kit For Better Fuel... 
California's latest tactic to promote electric-car adoption is to involve electric utilities in the installation and operation of charging infrastructure. Utilities in other states were previously allowed to own and operate electric-car charging stations, but that wasn't the case in California until a state Public Utilities Commission ruling in...
