Global solar flight to start, end in Abu Dhabi

DUBAI, United Arab Emirates (AP) — A Swiss-made solar-powered aircraft is planned to start and finish its first round-the-world flight from the United Arab Emirates capital of Abu Dhabi, a government-backed renewable energy company in the oil-rich Gulf federation said Thursday.

The choice of Abu Dhabi as the launch site for the historic journey is likely to bolster the wealthy emirate's efforts to position itself as a champion of renewable energy. It controls the bulk of the vast petroleum reserves in the Emirates, a seven-state federation that ranks among the largest oil exporters in OPEC.

Renewable energy plan hinges on huge Utah caverns

CHEYENNE, Wyo. (AP) — A proposal to export twice as much Wyoming wind power to Los Angeles as the amount of electricity generated by the Hoover Dam includes an engineering feat even more massive than that famous structure: Four chambers, each approaching the size of the Empire State Building, would be carved from an underground salt deposit to hold huge volumes of compressed air.

The caverns in central Utah would serve as a kind of massive battery on a scale never before seen, helping to overcome the fact that — even in Wyoming — wind doesn't blow all the time.

Car-mounted technology called flutter-driven triboelectrification has the potential to generate enough energy to charge a cell phone or tablet, according to Korean researchers writing in the journal Nature Communications, the Los Angeles Times reports.

Things to know about $8B wind energy proposal

CHEYENNE, Wyo. (AP) — An alliance of four companies has proposed an $8 billion project to supply the Los Angeles area with large amounts of electricity from a wind farm in Wyoming. Here are a few things to know about the ambitious project:

Wind energy proposal would light Los Angeles homes

LOS ANGELES (AP) — The push for clean energy to reduce greenhouse gases has led to multibillion-dollar investments in wind and solar projects, but finding an economical way to store renewable energy that comes and goes like the breeze or the sun has proved challenging.

An alliance of four companies say they have found an answer in an underground salt formation.

The owners of the Ivanpah solar project in the Mojave Desert -- including NRG Energy, Google and BrightSource Energy -- have applied for Treasury Department grants even as they have delayed paying back millions borrowed through Energy Department loans, according to documents tracked by The Wall Street Journal.

Proposal would send Wyoming wind energy to LA

LOS ANGELES (AP) — Four companies proposed an $8 billion project Tuesday that within a decade could send wind energy generated on the plains of Wyoming to power-thirsty households in Southern California.

The sprawling project — if approved and financed — would create one of the country's largest wind farms 40 miles north of Cheyenne, a huge energy storage site inside caverns in a Utah salt formation and a 525-mile electric transmission line connecting them.

US, California release roadmap for solar projects

SAN FRANCISCO (AP) — State and federal officials sought Tuesday to bring order to California's boom for renewable-energy plants in the Mojave and other southern California deserts, releasing a roadmap covering 22.5 million acres that designates some areas for large-scale solar, wind and geothermal plants and others for conservation of desert habitat and animals.

"We have amazingly special places here," U.S. Interior Secretary Sally Jewell said in a news conference at a desert wind farm near Palm Springs with U.S. Sen. Barbara Boxer and other officials releasing the multi-agency draft plan.

Brown signs Calif. clean-air vehicle legislation

SACRAMENTO, Calif. (AP) — Gov. Jerry Brown signed into law several bills designed to boost use of clean-air vehicles in California.

One bill signed Sunday allows 15,000 additional electric and partial zero-emissions vehicles, or 70,000 total vehicles, to get green stickers that allow driving in carpool lanes even when solo.

Another requires freeway high-occupancy toll lane operators to allow clean air vehicles to drive for free or reduced rates. Such roads exist in Orange and Riverside counties, and the San Francisco area.
