Former U.S. Energy Secretary Dr. Steven Chu, who oversaw a doubling of renewable energy

Former U.S. Energy Secretary Dr. Steven Chu, who oversaw a doubling of renewable energy deployment from 2009-2013, addresses if falling fossil fuel prices threaten wind and solar power.

Chu explains that 78% of U.S. economies have state-mandated renewable portfolio standards, requiring a fraction of clean energy. Renewables, currently supplying 13% of U.S. electricity, have seen significant cost reductions. Wind power, even without subsidies, is nearly as inexpensive as natural gas.

Solar generation in sunny regions nears cost parity with new natural gas plants. Wind and solar costs are projected to decline for decades, potentially making them competitive with any new energy source across much of the U.S. within a decade.

Arctic sea ice has reached a record low wintertime maximum extent for the second consecutive year. Scientists from the National Snow and Ice Data Center and NASA reported this finding, noting the extent reached 5.607 million square miles on March 24. This represents the lowest maximum extent recorded in the satellite era.
