The devastated Fukushima Daiichi nuclear power plant has become the latest poster child for long-standing issues surrounding nuclear energy – issues that need to be resolved to reduce the risk of a similar nuclear crisis in the United States. These range from the seemingly eternal conundrum over dealing with highly radioactive spent fuel, to fire hazards, plant design, and emergency plans, say nuclear engineers and nuclear-safety watchdogs.
Google is teaming up with an environmental group to map methane leaks from natural gas pipelines in US cities. Methane contributes to global warming, and Google hopes its new maps will encourage utilities to patch and replace old pipelines.
US ratepayers will pay 3 percent more for electricity this year – the biggest increase since 2008, according to US government projections. The higher prices come after a harsh winter that strained the Northeast's grid and boosted natural gas demand.
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.
The EPA will unveil new regulations to reduce carbon dioxide emissions from power plants by 30 percent by 2030. The EPA power plant rules are the most aggressive of President Obama's Climate Action Plan and have already provoked heated debate over a complex issue.
Owning a personal power plant could be the next big home appliance. Here is how the idea might not be that far-fetched.
Warming climates and rising incomes will lead to a surge in cooling-related energy use, according to the latest report by the Intergovernmental Panel on Climate Change. It's one of several ways global warming is set to alter global energy supply and demand.
The terrible Fukushima nuclear accident has not stopped Japan from revamping its safety measures and restarting its nuclear reactors. Thirty-five years after its far less terrible Three Mile Island accident, the US still hesitates to embrace nuclear power
The US Army has made some impressive commitments to renewable energy, Daly writes, in an effort to procure reliable and locally generated energy sources.
Natural gas is cleaner than coal, but only if the industry can control its methane releases. A new report says it's doing OK, but methane releases are underestimated.
