Delta Airlines has joined The Climate Registry after completing verification of its greenhouse gas emissions from 2005 through 2010. The airline has lowered its annual emissions by 7.6 million metric tons since 2005, a 17 percent reduction. The decrease was achieved through fuel-saving initiatives such as removing unnecessary weight, installing aircraft winglets, and replacing inefficient aircraft with newer models that produce fewer emissions per passenger. Delta is the first legacy carrier to meet the registry’s requirements. Last year, the airline joined the Center for Climate and Energy Solution’s Business Environmental Leadership Council.
A new study finds that wind and solar energy could power the entire U.S. grid 99.9 percent of the time, if combined with energy storage and fossil fuel backup for the rare times when clean energy alone was not enough. A mix of wind power, solar power and storage in batteries and fuel cells could exceed electricity demand while keeping costs low, the scientists found. The report, by the University of Delaware and Delaware Technical Community College, used computer modeling that explored 28 billion combinations of renewable and storage possibilities, each tested with four years of weather and energy demand data.
