Researchers have developed a sponge-like silicon they say could be safely used to store energy in batteries. Using this silicon in smartphone batteries, for instance, could allow batteries to last 30 percent longer than traditional lithium-ion batteries.
Ahead of next year's Paris climate talks, it's time for a new approach to climate change that supports making clean energy cheaper than fossil fuels without subsidies, writes Matthew Stepp of the Center for Clean Energy Innovation. The only way to do that is with more innovation.
South Stream, a proposed pipeline to bring Russian natural gas to southeastern Europe, threatens to undermine Europe's solidarity forged during the Ukraine crisis. Some see the pipeline as a necessary alternate supply of gas while others say it will only give Russia more leverage over European energy.
'Rolling coal,' the practice of blowing thick, black plumes of smoke from tailpipes, is gaining traction as a protest against growing environmental regulation. Rolling coal drivers sometimes spend thousands of dollars modifying their vehicle.
Two-bladed wind turbines aren't new to the world. But, a Chinese company is building a six-megawatt, two-bladed turbine that may generate as much power as the largest commercial offshore turbines.
Energy is a rare bright spot amid otherwise tense relations between the US and China ahead of an annual summit between the two superpowers this week. US officials say climate change and clean energy offer room for collaboration with their Chinese counterparts.
Climate change requires a rapid and dramatic decarbonization of the global energy supply, according to a new report. It comes as world leaders aim to learn from past failures in forging an international pact on climate change at international talks next year in Paris.
Researchers have presented an alternative nuclear reactor – one that floats on water. Although floating nuclear reactors at sea have some benefits, there are concerns with surrounding marine life and terrorism threats in the context of a post-Fukushima world.
Terrorists would like nothing better than to bring down Silicon Valley in one fell swoop. One way is to cut off its electric power. But PG&E is arming itself, too.
The Obama administration issued new support for offshore wind power projects this week as part of the president's Climate Action Plan. While land-based wind power has expanded in recent years, the renewable energy source has struggled to gain hold off the coasts.
The US oil boom has led a rise in oil and gas production. But, the US oil boom has also brought on several problems for local environments and economies, including possible contamination of drinking water.
Now that fracking bans are left for New York cities and towns to decide, the shale industry sees the state's court ruling as a missed opportunity for energy and investment. More than 75 towns in New York already ban fracking, which may make companies hesitant to invest.
North Dakota Gov. Jack Dalrymple wants to expand his state's oil pipeline capacity, after the state's oil production reached the 1 million barrels per day mark. But, many worry about the potential environmental consequences such as oil spills.
Fourteen percent of households on Native American reservations live without electricity. But several Native American reservations are now using renewable energy technology to access electricity and much needed income.
