From Virginia to Colorado to Washington, voters on election day 2013 threw their weight behind politicians and policies that limited the use of coal, oil, or natural gas. Bans on fracking, coal exports, and tar sands were on the ballot in a handful of states, and in most cases, the election day 2013 results did not favor fossil fuels.
Tesla Motors' (TSLA) third-quarter sales numbers came in under most analysts' expectations late Tuesday, and the electric carmaker's stock price plunged, triggering a 'circuit breaker' on the Nasdaq. But the fundamentals of Tesla Motors appear to remain strong, and the California-based company has plans for expansion.
Voters in Virginia narrowly elected Democrat Terry McAuliffe for governor over Republican Ken Cuccinelli II, who differed among other things on the future of the state's coal industry. Mr. McAuliffe supported new EPA regulations on power plants that will make it difficult for new coal plants to be bought.
India launched its first spacecraft to Mars Tuesday at a price tag of $72 million. It takes less fuel to propel India's Mars orbiter 485 million miles to the Red Planet than you think.
A new generation of 'smart' thermostats leverage cheap sensors, data analytics, and other bells and whistles of the IT world to take the guesswork out of programming your thermostat. It's an emerging field that is expected to grow as users demand more from their everyday devices.
Residents of four Colorado towns will vote on fracking bans Tuesday. Oil and gas production is growing in the western states, and what happens in Colorado is being closely watched in other shale-rich states.
Daylight saving time ends this Sunday, meaning peak heating and lighting season really ramps up. Daylight saving time is itself a means to save energy, but there are plenty of other ways to save money and energy this fall and winter.
Gas prices are continuing their downward slide, hitting the lowest average price since last December Friday. Gas prices are expected to continue to fall this year, and in many places, drivers are already paying less than $3 a gallon to fill up their gas tank.
The US will begin publishing annual reports on how much the government spends on fossil fuel subsidies. It's part of the White House's broader push to be more transparent in mineral wealth extraction, but there's debate over exactly what subsidies are and how important they are to US energy.
Defense Department plans to buy 92,000 hybrid and electric vehicles over the next seven years to trim its fuel bill. They could be especially cost-effective in war zones.
Happy Halloween: Trick or treat? Solar or oil? Even Halloween jack-o'-lanterns have joined the energy debate. When the Department of Energy promoted clean energy and efficiency as pumpkin-carving suggestions, the US oil and gas lobby served up its own Halloween ideas.
Keystone XL protesters used President Obama's Wednesday speech on health care to put the Canada-Texas pipeline back in the spotlight. Attention has shifted away from Keystone XL in recent months as fiscal debates and health care have overshadowed climate change in Washington.
The US will end financial support for new coal projects overseas, except in narrowly defined circumstances, to address rising greenhouse-gas emissions. Can clean energy alone alleviate energy poverty?
Three western states have joined British Columbia in a regional scheme to put a price on carbon and implement other emissions-reducing policies. If successful, it could be a model for other regions, but questions remain over the efficacy of taxing carbon.
Strong inventories have pushed US oil prices down into double digits, after three months above the $100 range. It's a lift for the US economy, even though the suddenly booming US energy industry will take a small hit.
Two US citizens were kidnapped from an oil supply vessel off the coast of Nigeria. The incident highlights piracy's shift westward from East Africa – tighter security and the promise of new oil have made the continent's western coast an increasing target for pirate attacks.
Technology and geology are converging to unlock billions of barrels of oil across much of Africa in the coming decade. Can Africa avoid a 'resource curse' and leverage its mineral wealth to fuel economic development?
US carbon emissions fell in 2012 – again – after peaking in 2007. The Great Recession and a boom in cleaner natural gas are widely credited as driving the reduction, but broader, longer-term shifts are also changing the way Americans use energy.
Gas prices have plateaued in the past week, but analysts expect fall's broader downward trend to pick up pace again as cooler weather prevails and demand for gas dwindles. National gas prices are likely to get tantalizing close to – but not quite at – $3 a gallon.
Four decades after the 1973 Arab oil embargo, the US has more efficient cars, a strategic oil reserve, and a homegrown energy boom that is reducing its reliance on OPEC oil. But oil prices remain high and some see the nation's newfound resource wealth as a boom that will eventually go bust.
