"Maxwell Technologies (NASDAQ: MXWL) provides R&D services to the U.S. military and other government agencies; it's become the world's leading authority on ultracapacitors," says Timothy Lutts.

In The Cabot Stock of the Month report, he explains, "Ultracapacitors are handy little electronic devices that store and release electric energy more efficiently than batteries; they can be 10 times lighter than batteries and store and distribute energy 10 times more effciently than batteries."

"So what are ultracapacitors good for? Today, Maxwell-the primary American ultracapacitor manufacturer-is focusing its efforts on two fast-growing young industries: wind turbines and hybrid/electric vehicles.

Brendan Coffey is a specialist on "green" investing; in his The Cabot Green Investor, he looks to alternative energy firm American Superconductor (NASDAQ: AMSC).

Here's his review of the company, which is a player both in wind power and energy efficient wiring that can play a role in improved power grid systems.

"Long an R&D company, focusing on highly conductive wiring, American Superconductor made a game-changing purchase of an Austrian wind company, Windtec, in early 2007.

"President Obama has stated that he's been studying Roosevelt's first 100 days and the way out of the current economic mess will look a lot like the New Deal," says David Fessler.

The advisory panelist for The Oxford Club explains, "Seventy-five years after Roosevelt's inauguration, I think we will soon see President Obama get the ball rolling on his version of the New Deal, focused on two very specific areas: energy and infrastructure." Here, he looks at stocks poised to benefit.

"Saving energy will be one of his first initiatives. It's what will give us the quickest bang for our buck. Better insulation in homes, programmable thermostats, fluorescent bulbs, more fuel-efficient cars, energy management systems for use in larger-scale commercial buildings and beefed-up public transportation are just a few of the ways to save energy.

"The government will likely offer attractive tax incentives to rally support. So who stands to prosper from such initiatives?

"Big blue-chip companies, like Owens Corning (NYSE: OC), maker of insulated glass and building insulation; General Electric (NYSE: GE), manufacturer of wind turbines, energy control and infrastructure products; and Johnson Controls Inc. (NYSE: JCI), maker of energy management systems (for buildings and vehicles) and hybrid vehicle batteries.

Energy producers may soon notice the decided shift in the wind in Washington, political and otherwise.

After consulting with Congressional Democrats, President-elect Barack Obama moved quickly to double his proposed tax credit for renewable energy in his fiscal stimulus package to $20 billion. The Obama Administration's overall fiscal stimulus package is expected to total about $700-$850 billion.

New 'sheriff' in town

Economist Peter Dawson told BloggingStocks said Obama's energy discussions with Democrats on Capitol Hill display both Washington savvy and a decidedly new energy tone inside the corridors of power.

"First, Obama, so far, is making good on his 'all ideas considered' philosophy. Congressional Dems wanted a renewable energy tax credit program that will help speed the development of solar and wind power, and $20 billion in 2009 will further that goal. So Obama's collaborative decision making process is being deployed," Dawson said

With oil prices cut in half and gasoline near (or below) $2 per gallon, is now a good time for the U.S. to end its century-long addiction to oil?

The topic was raised by none other than the 'liberal bastion' of The Wall Street Journal Monday (subscription required0 with energy analysts and policy makers weighing in.

BloggingStocks Monday asked Energy Trader Jim Dietz to evaluate some of the major recommendations discussed.

• Four-day work week: "It's possible, but the best plan would be voluntary, allowing companies to opt in/out and adopt plans that meet their production needs," Dietz said.

• Mandated higher MPG for vehicles: "This is almost certain to be proposed by President-elect Obama, and will likely pass the Congress. It will reduce gasoline and diesel consumption."

• Mandated flex-fuel cars: "Another measure likely to become federal law and it would take pressure off oil consumption."

• Tax credit for fuel-efficient vehicles: "Another oil saver, and it stands a better than 50% chance of being passed by the next Congress."
  

• Federal funds for next-gen vehicle: "This will likely be included in any rescue package for General Motors, Ford, and Chrysler. A next-generation vehicle would be a game-changer, energy wise, but it's years away."

"Our hope is that the new administration decides to fund 'the future'," says Sean Broderick. In Money and Markets he looks to some favored exchange traded funds offering long-term investors exposure to alternative energy, wind power, electric cars and the rebuilding of our nation's infrastructure.

"We need an efficient power grid that can carry renewable energy -- solar from the Mojave Desert and wind from the Great Plains -- to the population centers of the U.S. Too bad our power grid is 100 years old and falling apart at the seams. And demand is growing every year.

"In addition, we need more railroads for an energy independent America. Building those lines is a good bottom-up way to boost the economy. And we need an electric car program.

"I'm talking about developing mass-market battery-powered cars (hybrid or plug-in) that achieve at least 100 mpg of gasoline on new fleets by the year 2015.

"These three programs have one thing in common: Good American jobs that can't be shipped overseas. If you want to jump-start the economy, that's a 1-2-3 that might work.

If you're an economist, like David H. Wang, you wake up some days muttering, "What has happened to the industrial base in the U.S. economy?"

The auto companies are practically on life support, and other sectors are paring-back operations, even as international competition mounts. Hundreds of thousands of jobs have been lost. How did this happen? Eight more years of industrial base decline without a viable plan to counteract it? And now, as a result of the financial crisis and de-leveraging, the prospect of a period of less-available credit threatens to delay economic recovery.

Well one remedy for the above, Wang argues, is to invest in the industrial sector via investing in the United States' infrastructure. And what's one project worthy of consideration? Investor T. Boone Pickens' plan to substantially increase domestic wind power via his Pickens Plan, Wang argued.

Pickens' investment fund has fallen on tough times, as of late. His BP Capital investment fund has shrunk by 60%, due to energy sector losses, and will drop to about $500 million after redemptions, by week's end, Pickens told CNBC Thursday. Pickens, who sees oil sector consolidation, expects the price of oil to recover to $100 per barrel in 2009. Oil Thursday closed down $1.81 to $65.69 per barrel.

Pickens Plan: a better investment than AIG?

Wang is less certain about a $100 oil price in 2009, but he is certain about the merit and benefits from investing in Pickens' project, and his argument is compelling. (Wang added that he does not have an investment stake in any power/energy company.)

"The positive side to any correction is that it brings valuations down to earth for stocks you may have thought were out of your reach," says Genia Turanova.

The contributing editor to Stephen Leeb's The Complete Investor explains, the "Along with the energy sell-off, unregulated utilities have declined even more-to bargain levels." Here's a look at Florida-based FPL Energy (NYSE: FPL).

"FPL is one of our favorite alternative energy holdings. And with the recent selloff, its yield once again qualify the stock as a legitimate full-fledged income plays.

"And as its quarterly results indicate, the unregulated utility is relatively immune to the nation's slowdown, making them among the surest growers in the marketplace today.

"The skies over the Sunshine State have been quite dark because of the housing sector's woes and the subsequent credit crunch. As a result, the Florida-based company's adjusted earnings per share increased 'only' 8% on a year-over-year basis.

Wind and solar, two renewable energy sources with a promising future, nevertheless face a bottleneck of sorts in the United States: the electric power grid. The existing grid can not handle the new demands, The New York Times reported Wednesday, forcing renewable wind and solar sites to shut down, even when conditions are right to generate and sell power.

An infrastructure-challenged U.S.

Economist Glen Langan says there's a theme that keeps popping up in the U.S. economy in the early 21st century: inadequate infrastructure. "We're a nation of inadequate infrastructures: the power grid, air travel/air traffic control, railways, highways... pick an infrastructure and you'll see a network that can't handle present demands, let alone an expanded national economy in 2020 or 2030," Langan said.

The power grid bottleneck is particularly frustrating and damaging because both wind and solar power generation systems are mushrooming, and could, with an adequate grid, account for more than 20% of the nation's power needs, Langan said, adding that some economic models put renewable energy's potential contribution even higher, at 25% or more.

"Imagine T. Boone Pickens building his massive, multi-billion dollar wind mill farm and having it sit idle because the grid cannot tolerate and transmit the increased power? Pretty sad," Langan said.

"We've looked at several ways to play anticipated growth in wind energy; we've also considered titanium makers for that industry's ties to the production of lightweight, modern aircraft," notes Bill Martin.

In his BullMarket.com, he explains, "While the two trends might not appear to have much in common at first glance, Hexcel Corp. (NYSE: HXL) offers a way to play both the aircraft and wind markets.

"The connection is the lightweight, composite materials Hexcel makes that are used by producers in both sectors. Hexcel develops and manufactures advanced structural materials.

"It is the largest U.S. producer of carbon fiber; the world's largest weaver of reinforcement fabrics; and the number-one producer of composite materials.

"Its product was initially developed for the aerospace industry, but is now used in a wide range of applications -- from golf clubs to satellite arrays, and from the rotor blades of wind turbines to life-saving monocoques for Formula 1 race cars.

"It's been a rollercoaster ride for Hexcel's stock in the past 12 months. The shares hit their one-year peak of $27.19 in December 2007; by January 22nd they had plummeted to $17.. The shares rebounded through May, only to fade again. Year to date, HXL is off about 15%.

"Around the globe, wind-generating capacity has been expanding at a rapid 30% clip in recent years," notes value investor Nathan Slaughter, who adds, "And 2008 is already shaping up to be even better."

The editor of Half-Priced Stocks looks at industrial product firm Trinity Industries (NYSE: TRN), explaining, "The company's most promising division is involved in the production of structural wind towers." Here's the advisor's of the latest addition to his "deep-discount' model portfolio.

"Led by states such as Texas and California, wind farms around the country will generate almost 50 billion kilowatt hours of electricity this year. Of course, the U.S. is still playing catch-up with many other regions.

"In fact, countries such as Spain, Portugal and Denmark all rely on wind farms for as much as one-quarter of their total power needs. Across Europe, wind turbines will account for roughly one-third of all new generating capacity installed over the next few years and could provide electricity for 90 million people by 2010.

"The outlook is even brighter in many booming, energy-hungry Asian markets. In China, installed wind power capacity surged +130% last year and will reportedly supply a great deal of the electricity needed for the upcoming 2008 Beijing Olympic Games.

"Thanks to the great strides in engineering, wind turbine output has increased by a factor of ten (or higher in some cases) over the past decade.

"There's no 'silver bullet' solution to the energy crisis; but there are some solutions that do work," says Sean Broderick, referring to wind and solar power.

In The Safe Money Report he says, "There are with some choice ETF to power your own bottom line." Here's a look at the two green technologies and how you can invest in these developing fields.

"Many Americans are disgusted by the fact that, faced with an energy crisis, the government seems to produce nothing but hot air. So let me give you my appraisal of two alternative energy solutions that work -- along with some choice exchange-traded funds that can power your own bottom line. Here are two energy solutions that work right now.

Solution #1: Wind Power

"Critics will point out that the wind seems to stop blowing when you want electricity most -- on hot summer days. And that is a problem. However, a study last year by Stanford University shows that wind power from interconnected farms can be used as reliable base load electric power.

Billionaire oilman T. Boone Pickens has launched a new campaign to substitute at least a portion of the U.S. imported oil with domestic natural gas.

Pickens would like renewable energy sources, wind power chief among them, to run electric power generation plants currently run by natural gas/coal, and use that natural gas to fuel natural gas vehicles.

Economist Glen Langan told BloggingStocks Thursday the PickensPlan is commendable for a number of reasons (it would lower the trade deficit, create domestic jobs, and decrease greenhouse gas emissions), but investors and readers should not view it as a panacea for the nation's transportation energy bill. "It could be a part of the solution, but it won't address the entire imported oil problem," Langan said.

Another oil saver: better engines

What's another key to reducing both imported oil and U.S.-produced oil consumption? Something that the U.S. auto sector has under-emphasized for more than a decade: technology-driven increases in car/vehicle efficiency, Langan said.

Langan said vehicle weight reduction, transmission/drive train improvements, enhanced aerodynamics, and the biggest factor -- increased engine efficiency -- "have the potential to reduce oil imports by almost as much as the Pickens Plan, and the changes won't take 10 years to see the results."

Further, many of the mpg-enchancing technologies already exist, Langan notes; he suggested an additional federal tax credit for automakers to help them incorporate the changes sooner.

"The fleet [all vehicles driven in the U.S.] should average 25-27 miles per gallon right now. Currently we're at about 20 miles per gallon. With appropriate federal tax credits we could be at 30-32 miles per gallon in five or seven years," Langan said.

"Wind power is a source of energy that is renewable, clean, has a low operating cost and is a technology that's been around for over century," says Ian Cooper.

The small-cap stock specialist and editor of the SC Trading Pit explains, "That's why we're adding a position in First Trust ISE Global Wind Energy ETF (NYSE: FAN), which lets you own 52 wind stocks at once."

"The nice thing about this ETF is that many of the holdings are non-US companies, meaning they're not reliant on news of green energy tax credits. But with the rest of the world investing in wind, we're given wider profit exposure. This is a great way to hold 50 up and coming stocks at $30 a pop.

"As oil prices stay high, the wind power and alternative energy themes are becoming increasingly popular, making the latest exchange-traded fund even more enticing.

"Just recently, the much-anticipated First Trust ISE Global Wind Energy ETF was launched. And not only will investors have an opportunity to profit from companies in the wind energy business, they can profit from companies that will soon enter the space.

"To say that alternative energies are critical is a severe understatement." asserts Stephen Leeb, who looks at three plays in the sector that earn a spot in his Growth Portfolio.

The editor of The Complete Investor explains, "Readily scalable energy sources such as solar and wind account for under 1%. It's time to get serious."

Three of the stocks he has selected are holdings in his model Growth Portfolio: FPL Group (NYSE: FPL), Exelon (NYSE: EXC), and General Electric (NYSE: GE). Here's a trio of favorites.

"We have focused on those alternative energy stocks with the strongest growth profiles. None is a pie in the sky fantasy; all provide energy in the here and now and have significant and fast-growing revenue streams.

"The fact that their growth should continue to burgeon is one of the most heartening pieces of news on the energy front. We could argue that investing in these stocks not only will be good for your portfolio but is an act of patriotism as well.
