Solar Wind

While President Obama has made development of cleaner energy sources a priority, an effort is underway to close off a large swath of the Southern California desert to solar and wind energy projects. In a move that could pit usual allies -- environmentalists and the solar and wind industries -- against each other, Sen. Dianne Feinstein (D-Calif.) is preparing legislation that would permanently put hundreds of thousands of acres of desert land off limits to energy projects.

The solar wind -- a stream of charged particles ejected from the sun's upper atmosphere at 1 million mph -- is significantly weaker, cooler and less dense than it has been in 50 years, according to new data from the solar probe Ulysses. The cause seems to be a change in its magnetic flux, said Dave McComas of the Southwest Research Institute. Why it's happening is a mystery, but it has fluctuated like this in the past. Normally the sun goes through an 11-year cycle of more, then fewer, sunspots and a similar solar wind cycle.

Data from the Japanese Hinode spacecraft have confirmed that a set of long-theorized magnetic waves help power the solar wind that drives charged particles to the frigid boundary of the solar system. Called Alfven waves in honor of the Swedish scientist who proposed their existence 60 years ago, they play an important role in accelerating the solar wind to speeds of about 2 million mph, according to results published today in the journal Science.

Before power lines, homesteaders had no choice. They lighted their lanterns, stoked their fires and packed away winter ice against sizzling summers. Owners of about 250 homes in the Three Rivers community near this central Oregon lake are far from homesteading or camping out. But they are among a growing number of Americans who shun power lines, choosing to live "off the grid," without commercial power.

The United States has not joined the Kyoto Protocol to cut greenhouse gases, but the pact nevertheless is boosting sales for American companies that market "clean" energy technologies. The spread of renewable-energy standards -- particularly in Europe -- propelled by the treaty, along with a surge in oil and gas prices, has triggered a boom in business for solar and wind energy companies. When Solar Integrated Technologies Inc.

The Los Angeles Department of Water and Power will expand its use of solar, wind and other renewable power sources from 3% of its electricity portfolio to 20% by 2017, its governing board agreed Monday, although environmentalists said the goal should be met earlier. The board, which was appointed by Mayor James K. Hahn, approved the policy a little more than a month before Councilman Antonio Villaraigosa becomes mayor.

Most of the contents of NASA's Genesis space probe appear to be intact and usable despite the craft's crash landing in the Utah desert, researchers said Friday. "We should be able to meet many, if not all, of our science goals," said Roger C. Wiens of Los Alamos National Laboratory, a principal investigator. The $264-million mission was designed to gather components of solar wind and return them to Earth for analysis.

Los Angeles should more than double the amount of energy it generates from solar power, wind and other nonpolluting sources by 2017, the City Council's top advisor recommended Thursday, but some environmentalists complained that the plan is as hazy as Southern California on a smoggy day.

After 26 lonely years and about 8 billion miles of travel, the Voyager 1 spacecraft has become the first human-made object to leave the solar system. Maybe. A group of astronomers announced Wednesday that Voyager 1 had crossed the "termination shock" at the edge of the solar system where the sun's powerful influence wanes and the solar wind drops from supersonic speeds to a relative whimper.
The Senate on Thursday rejected a measure to require that 20% of the nation's electricity be produced from renewable sources such as solar and wind power by 2020, dealing environmentalists their latest defeat on energy policy. The action came a day after the Senate, as it debates legislation focusing on a variety of energy issues, refused to set tougher fuel-efficiency standards for cars, SUVs and other vehicles. The measure on renewable energy sources, sponsored by Sen. James M. Jeffords (I-Vt.
