T. Boone Pickens, the Texas oilman turned clean-energy crusader, knows how to grab the spotlight.

He did it last week at the Democratic National Convention, where he pushed his proposal to spread high-tech windmills across the Great Plains and fuel many of America's trucks and cars with natural gas. He plans a repeat performance this week at the Republican National Convention, corralling any party officials and journalists willing to listen.

He's already had face time with both parties' presidential candidates, Republican Sen. John McCain and Democratic Sen. Barack Obama. NBC's reluctance last week to air one of his energy ads only gave him more publicity.

So will his plan work? Energy analysts say parts of it seem plausible, other parts don't and the timetable is probably unrealistic. It also would substitute one expensive fossil fuel for another.

Here are the basics of his plan:

Pickens wants to generate at least 20 percent of the nation's electricity from windmills, replacing electricity from traditional power plants that run on natural gas. He would take the natural gas that would have been burned in those plants and use it to fuel trucks and cars instead. That would cut U.S. oil imports by one-third, he estimates, saving the country about $230 billion annually.

And he wants to do all this in roughly 10 years.

"We've got to get off the foreign oil," said Pickens, in a meeting with Chronicle reporters and editors. "We have to get our country to the point where we're working on the problem and we're not drifting."

Pickens has extensive financial investments in natural gas and wind power and stands to benefit if the adopts his plan. But he says it's the only feasible way to make a quick, deep cut in the $700 billion the country spends on imported oil each year, an expense slowly bleeding the economy to death. (That figure assumes an oil price of $142 per barrel. At today's price, roughly $115 per barrel, the total spent on imports each year would be $565 billion.)

"You can forget about health care, education, social security - because we won't be able to afford it," Pickens said.

Energy analysts say the country could eventually get 20 percent of its power from the wind, but probably not in 10 years. A U.S. Department of Energy study earlier this year found that the country could reach that figure by 2030 - with effort.

"It's a pretty tall order to put that much wind capacity in place," said Chuck McGowin, senior project manager at the Electric Power Research Institute in Palo Alto.

$1 trillion estimate

Hundreds of thousands of windmills would need to be installed throughout the country's plains, at a price that Pickens estimates between $750 billion and $1 trillion. New transmission lines - worth $64 billion to $128 billion - would be needed to carry all that power to cities.

The price alone is daunting, although Pickens notes the money would stay in the United States rather than flow to overseas oil producers. Also complicating matters: Proposed wind farms and transmission lines often run into fierce opposition from neighboring communities, making quick construction unlikely.

"Just getting acceptance from the local populations can be a challenge, and could become more of a challenge in the future if we build out as much as proposed," said McGowin, whose organization conducts research for electrical utilities.

Even if all those windmills get built, few energy analysts expect the country to stop building new natural gas power plants or close existing ones.

"Those aren't going to go anywhere," said Ken Medlock, an energy research fellow at Rice University's James A. Baker III Institute for Public Policy. "We're not going to back out of gas."

Natural gas burns cleaner than coal, making it an increasingly popular fuel for power plants. Gas plants also produce fewer greenhouse gas emissions.

Much like oil, natural gas has experienced wild price spikes in recent years. Also like oil, natural gas production in the United States peaked decades ago, in 1973. Although production has risen sharply in the last two years - the result of high prices - it is still 11.3 percent below the peak of 21.73 trillion cubic feet.

That means converting a large percentage of America's millions of trucks and cars to run on natural gas could push up the fuel's price, if gas production and imports don't rise.

Costly switch for Detroit

The switch also would be expensive for Detroit and for drivers, since vehicles running on compressed natural gas tend to cost about $3,000 to $5,000 more than similar vehicles burning gasoline.

"It's not particularly realistic," said Patricia Monahan, deputy director of the clean vehicles program at the Union of Concerned Scientists. "It's going to be a big price tag."

Monahan considers compressed natural gas an excellent fuel for running small fleets of vehicles, such as buses and garbage trucks. But she questions the wisdom of trying to replace large amounts of imported oil with another fossil fuel, especially considering that the United States already has to import 19 percent of the natural gas it uses.

"We don't want to replace one import with another," Monahan said.

Pickens says the switch to natural gas as a transportation fuel wouldn't be permanent. He considers it a temporary measure, lasting perhaps 20 to 30 years before the world moves to some form of electric transportation.

He also says the country will soon have more natural gas at its disposal. Large underground deposits of natural gas trapped in shale lie beneath Arkansas, Louisiana, Oklahoma, Texas and several Appalachian states. Shale gas deposits are harder to tap than ordinary gas reservoirs, but high prices and advanced technology have triggered a drilling rush. As a result, Pickens said, U.S. natural gas production will soon top the old, 1973 peak.

"The shale has bailed us out, here," he said. "You'll see natural gas reserves double in the next few years."

Shale boom predicted

Although their numbers differ, many analysts agree that shale gas development is poised to boom - and increase the U.S. natural gas supply. Robert Clarke, an analyst with the Wood Mackenzie consulting firm, said gas production from underground U.S. shale deposits could jump 160 percent by 2014.

"That's just phenomenal growth," he said. "It definitely appears this will raise our total production."
