As Japan moves forward with its energy future after the Fukushima disaster, it tries to balance stable electricity with public safety. Will Japan return to nuclear energy?
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.

Smart parking uses low-cost sensors, real-time data collection, and mobile-phone-enabled automated payment systems that help drivers quickly find a parking spot, Rucks and Guevara-Stone write. The system reduces car emissions in urban centers by reducing the need for people to needlessly circle city blocks searching for parking.
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.
Oil companies operating in the once-mighty Libya are reviewing their commitments more than two years after the revolution there. Further west, however, sits Morocco, where some oil companies are eagerly laying the groundwork for what could be a major oil and gas bonanza.
The US is relying less and less on foreign suppliers to meet its energy needs, but US Energy Secretary Ernest Moniz says lauding those gains may be misguided in the drive for energy security.
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.
