"A smart grid is one of the holy grails of 'green' technology, enabling utilities to deliver resources when and where they're needed and reduce resources when they're not," says Brendan Coffey.

In The Cabot Green Investor, he explains, "There are larger companies in the smart metering arena, but Echelon (NASDAQ: ELON) has posted some significant wins in the marketplace recently and appears primed to generate more."

"Right now, grids are set up to provide as much power as needed at peak times, all the time. Studies show that when customers are part of a smart grid, and have more information to reduce energy usage, demand is slashed by up to 50%, particularly in areas where rates are discounted depending on the time of day.

"If there was ever a stock we can hold for a few years, natural gas company Chesapeake Energy (NYSE: CHK) is it," says Ian Wyatt. Here's the latest from his Top Stock Insights.

"Chesapeake Energy is the largest independent natural gas company and most active driller of wells in the US. Its operating activities include the onshore exploration and production of natural gas.

"The Obama administration is keen on achieving energy independence for the US. Natural gas is a good option for energy, since it is inexpensive, clean and domestic. I believe the administration will continue to push natural gas as an alternative to oil, and create incentives for the industry.

General Electric Company (NYSE GE) plans to ramp up its solar power division. GE already has a foot in the market, but up to this point it has produced only $200 million in sales.

GE made a minor acquisition in the solar field with the purchase of Astropower, and it acquired a stake in PrimeStar Solar. Now GE is taking a long-term view of the energy market and sees it as a multi-billion dollar industry. Jeff Immelt, GE's chief executive officer, told the Financial Times that energy was "clearly one of the big industrial businesses filled with what I would call seismic change, whether it's clean energy or scarcity of resources."

If you want to feel like what you do for a living makes a difference, you'll soon face an embarrassment of riches.

The alternative energy industry -- the green business -- is about to ramp up its hiring, with the next year likely to show an increase in demand, according to U.S. Labor Secretary Hilda Solis.

According to the chief economist at the International Energy Agency (IEA) in Paris, the world could be hurtling toward an energy crunch that could effectively kill any global economic recovery. Dr. Fatih Birol said in an interview that most major oil fields in the world have eclipsed their peak production. Birol noted that the public and many governments are oblivious to the fact that oil is running out faster than earlier predicted, with global production likely to peak in roughly 10 years.

Birol said, "One day we will run out of oil, it is not today or tomorrow, but one day we will run out of oil and we have to leave oil before oil leaves us, and we have to prepare ourselves for the day. The earlier we start, the better." It will not be cheap to convert from our dependence on oil, but the cost may be better than the possibility of having no oil whatsoever; or having $200-per-barrel oil.

"No US utility owns more of them than Exelon Corp. (NYSE: EXC), with 17 reactors," explains Roger Conrad, who chose the stock as his latest "growth spotlight" in The Utility Forecaster.

"Carbon free and, above all, paid for, existing nuclear plants are among the most prized assets in the power business.

"Some 80% of company earnings come from its unregulated generation fleet, 90% of which is nuclear. And it's by far the best-positioned US utility to ramp up nuclear output.

"I'm adding Itron (NSDQ: ITRI) to my diversified portfolio of stocks in the alternative energy space," says Elliott Gue.

In The Energy Strategist he explains, "The firm will benefit from both the HR 2454 bill (a cap-and-trade system designed to reduce U.S. greenhouse gas emissions) and the stimulus bill which included direct subsidies aimed at promoting efficiency and building a more intelligent electric grid.

"Itron is a leading play on energy efficiency and smart grid technologies, a key, near-term component of cutting carbon emissions.

"Itron (NASDAQ: ITRI), which is involved in the build-out of smart grids -- has been our radar screen for awhile," says growth stock expert Toby Smith.

In his ChangeWave Investing, he suggests, "As the top supplier of smart meters and meter infrastructure for the electricity industry, Itron is by far the best-positioned company for the smart grid build-out."

"The build-out of smart grids employs technologies that deployed across an energy grid which allow greater efficiency and flexibility during energy distribution and transmission.

"The cool thing about smart grids is that they are capable of isolating and better managing power outages and disruptions, integrating local power generating equipment, and avoiding electricity congestion or bottlenecks.

"Over the past year, ITC Holdings (NYSE: ITC) has been focused on identifying ways to integrate wind and other renewable resources into the power grid," notes growth stock expert Alexander Green.

In The Oxford Club Communique, he explains, "This young company -- that despite being in the midst of the biggest economic slowdown in more than 70 years -- is taking in more than $600 million in annual revenue, enjoying 46% operating margins and experiencing 72% quarterly profit growth.

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.

"Zero greenhouse gas emissions, 90% average availability as a power source, minimal land requirements and competitive costs: those are just a few of the advantages of geothermal power," explains Roger Conrad.

In his leading-edge New World advisory, he looks at one favorite play on the sector: Ormat Technologies (NYSE: ORA), which operates a dozen geothermal plants worldwide.

"Geothermal's chief disadvantage is geographical limitations to large-scale applications. Geothermal plants are mainly economic in areas of subsurface or volcanic activity.

The U.S.'s country & western culture has a saying that goes, 'I was country, before country was cool.'

Well, billionaire oilman T. Boone Pickens was "bullish on oil, before being an oil bull was cool." And, despite the bursting of the leverage-influenced oil bubble, during which oil plunged from $147 to below $40 in less than a year, Boone-Pickens is still bullish on oil, long-term.

"The solar sector has been notably weak, including First Solar (NASDAQ: FSLR)," says Stephen Leeb. Despite the setback, the editor of The Complete Investor rates the stock a high risk buy.

"First Solar is one of the few whose earnings outperformed consensus estimates: its fourth-quarter results reported yesterday after the market's close were nearly 25% better than estimates.

"First Solar made $1.61 per share this past quarter; Wall Street was expecting $1.30 per share. Revenues were also ahead of estimates, although the company reduced 2009 revenue estimates by about 10%, citing short-term credit concerns for customers.

"American Superconductor (NASDAQ: AMSC) should benefit from an update of the nation's power grid," says Jim Powell.

Here, the editor of Global Changes & Opportunities Report reviews this leading manufacturer of more efficient high temperature superconductor-based wires and cables.

"I've been writing about infrastructure stocks ever since it became apparent that big federal spending programs were on the way. I believe American Superconductor will perform very well. In fact, its price has already started to rise.

"American Superconductor is not yet profitable. However, the company is well past the development stage. AMSC makes high temperature superconductor (HTS) wires and cables that carry as much as 150 times the current as conventional products of the same weight and diameter.

"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.
