"The trick within the solar sector is to home in on the stock within the group that has the best shot at putting on a great show," says Paul Goodwin.

The editor of Cabot China & Emerging Markets Report explains, "And we think that stock is LDK Solar (LDK), a company that is displaying and forecasting some of the most dynamic growth of any company we follow -- solar or not.

"LDK Solar got its start in 2005 and came public during the glory days of 2007-the stock nearly tripled from its IPO in June to its top that fall. The company's claim to fame was its polysilicon and ingots, two of the base supplies needed to make most solar cells and modules.

"Ultracapacitors are lighter and more powerful than batteries, 10 times more powerful by size as well as 10 times lighter," notes Brendan Coffey.

The editor of Cabot Green Investor explains, "Within this market, Maxwell Technologies (MXWL) is a San Diego-based company whose patent-protected ultracapacitors are denser -- and therefore able to hold more energy -- than those of its competitors.

"In a simplified comparison of how powerful and quick Maxwell's ultracaps are, a lead acid battery takes 10 hours to fully charge. A lithium ion battery will charge in about an hour.

"The 'sleeper' story of 2011 will be cellulosic ethanol, a biofuel made from the sugar in plants (instead of the starch in corn)," says Andy Obermueller.

The editor of Fast-Track Millionaire explains, "New EPA rules increase the amount of ethanol that can be blended with gasoline by +50%, and federal law calls for the nation to produce gobs of this so-called 'advanced biofuel.'

"Cameco (CCJ) is a Canadian miner and the second largest producer of uranium in the world," says Brendan Coffey.

The editor of the Cabot Green Investor explains, "However, the company is more than just a uranium miner. It also operates further up the nuclear supply chain, and has a goal of continuing to expand its related services.

"The company delivered 16% of world demand in 2009 and is aiming to double production by 2018. It has 'proven and probable' uranium reserves of 480 million pounds, enough to meet nearly three years of current global demand.

"China is quickly becoming the global leader in the development and production of alternative energy technologies," says Keith Fitz-Gerald.

The editor of The New China Trader suggests, "One way to play the trend is with Advanced Battery Technologies (ABAT), which engages in the design, manufacture, and marketing of rechargeable polymer lithium-ion (PLI) batteries.

"Founded in September, 2002, Advanced Battery Technologies is officially based in New York. However, it also keeps executive offices in Beijing and Hong Kong, while its manufacturing facilities are in China -- so for all intents and purposes this is a Chinese company.

"The real magic behind lithium is that, pound for pound, this featherweight metal can store more electric energy than just about any other material," notes Nathan Slaughter.

The editor of The ETF Authority explains, "That has made lithium the battery maker's best friend. And portable electronics, power grid infrastructure and hybrid vehicles are a powerful 1-2-3 punch that could send demand soaring.

"Unlike gold, silver and other metals, it's virtually impossible to invest directly in lithium. There are no lithium trading pits, no futures contracts, and no way to take physical possession. Global X Lithium Fund (LIT), a recently launched exchange-traded fund, is the next best thing.

"Cree (CREE) is a leading provider of light-emitting diodes (LED) and related technology; in my view, the company is in an excellent position to benefit from the "Green Revolution" taking place in the lighting industry," says Geoffrey Seiler.

The editor of BullMarket.com explains, "Operationally, the Durham, North Carolina-based company delivered solid results for the quarter ended June 27th, which was its fiscal fourth quarter of 2010.

"The company announced last night that it earned $52.8 million, or 48 cents per share, up from $9.7 million, or 18 cents per share, in the year-ago period.

"Cameco (CCJ) is the 'Superman' of the uranium world; the stock fits with our preference for owning tangible assets - the classic, durable means of wealth creation and preservation," says Chris Mayer.

The conrtributing editor to The Daily Reckoning explains, "Uranium ought to prove a wonderful inflation hedge if our thesis plays out. This is one to buy and sock away for a few years.

"Cameco Corp., based in Saskatchewan, Canada., is the only uranium blue chip. It is the second largest uranium miner in the world, after Kazatomprom. Cameco produced about 20 million pounds last year, or 16% of the world's supply.

"Our latest "Bargain Stock of the Month" feature is NextEra Energy (NEE), which changed its name in June from the FPL Group," notes Vita Nelson, who notes that the company changed its name to "better reflect the company's scale as one of the largest and cleanest energy providers in the nation."

The editor of MoneyPaper's Direct Investing exlains, "Its regulated utility, Florida Power & Light, provides electricity to 4.4 million customers. Its unregulated unit sells power across the United States.

"Over a third of this unit's operation sources electric power using windmills, many of which are located in high-wind areas, such as the Texas panhandle.

"I believe natural gas is the top energy play on the planet; natural gas produces far fewer greenhouse gases than oil or coal, it is easy to transport, and there is a lot of it," says Jim Lowell.

The editor of Global Changes & Opportunities explains, "EnCana (ECA) is my top choice as a natural gas investment. Long-term investors should be well rewarded for buying the stock at its current low price.

"During the past two years, there has been a revolution in the ability to extract natural gas from shale deposits, of which the U.S. and Canada have huge quantities.

"In your father's day, investing in energy was easy; fifty years ago, our fathers simply bought stock in one or two of the Seven Sisters oil companies, sat back, and let the money come in," says Martin Hutchinson.

The contributing editor to The Money Map Report explains, "The 'Sisters' owned pretty well all of the world's oil reserves. They had the world's best oil extraction and refining technology. They marketed the product to motorists, power stations, chemical companies, and all other users of the black gold. They made consistent profits, grew steadily as oil consumption increased, and paid good dividend."

"We have decided to go long in one sector that is in the midst of a rebirth -- the nuclear power industry where we have been bullish now for the last two years," says Steve Christ.

The editor of The Wealth Advisory explains, "While some think the nuclear revival is something new, this is one bandwagon we have been on for years. In recent years, the industry has been slowly rebuilding itself providing investors with a future growth opportunity."

"With sugar prices rising, our latest stock pick is the Brazilian ethanol and sugar producer Cosan Limited (CZZ)," says Brandon Clay. Here's the latest update from Invest with an Edge.

"Like all commodities, sugar prices are affected by the worldwide supply and demand of sugar. When there's a glut of sugar, prices fall. When sugar crops are threatened or supply is tight, sugar futures rise. That's what is happening now.
