energy efficiency

Total U.S. energy use fell 6.4 percent between 2007 and 2012, largely driven by advances in energy efficiency.

Total energy use in the U.S. was down in 2011 compared with 2010, mostly due to the use of higher-efficiency energy technologies in the transportation and residential sectors, as well as people driving less due to the high price of gas.

Green infrastructure can protect water quality and mitigate flooding while increasing energy efficiency, reducing energy costs, and improving public health, according to a joint report released by American Rivers.

A new study published in Nature Climate Change finds that policies focused on mitigating climate change would provide an effective means to simultaneously reduce air pollution, improve energy security, and achieve energy sustainability.

A new report finds that power plants around the country are stressing freshwater resources by consuming large volumes of water for cooling, and often discharging water that is 90°F or warmer, which can harm fish and wildlife.

A new study by the Pacific Institute examines the water requirements for current and projected electricity generation in the western U.S. in the area bounded by the Rocky Mountains to the east and the Sierra Nevada and Cascade Mountains to the west.

The Solar Foundation recently released its National Solar Jobs Census for 2011. According to the report, over the past year U.S.

A recent study in Climatic Change finds that the substitution of natural gas for coal initially increases global warming for many decades, rather than decreasing it as previously thought.

President Obama has announced that model year 2025 vehicles will be required to have a fuel efficiency standard of 54.5 miles per gallon. On top of helping drivers save $1.7 trillion at the pump and reducing oil consumption by 12 billion barrels a day, the increase in fuel efficiency is also expected to decrease greenhouse gas emissions by six billion metric tons.
