President-elect Barack Obama has often repeated his stance on alternative energy. He plans to spend $150 billion over 10 years on alternative energy, not only as part of his energy independence plan, but also in order to help clean the environment, and perhaps most important of all, to create 5 million new jobs.

With Obama winning in the polls, it is no wonder that on Tuesday solar stock prices soared: SunPower Corporation (NASDAQ: SPWRA) finished the day up 14.6%, Suntech Power (NYSE: STP) also closed 13.5% higher, Evergreen Solar (NASDAQ: ESLR) closed 12.8% higher, Canadian Solar (NASDAQ: CSIQ) was up 14.7% while Trina Solar (NYSE: TSL) gained 9.1%, First Solar (NASDAQ: FSLR) 9.6% and LDK Solar (NYSE: LDK) 4.8%. In fact, over the past week, these solar stocks added about 50% to their value: ESLR +104%, FSLR +55%, STP +53%, SPWRA +51%, LDK +48%, CSIQ +45% and TSL +41%. [Solar stocks are down this morning, seems to me a "sell on the news" decline.]

With these kind of gains recently you might think you're too late, but solar stocks have actually been beaten mercilessly in the past year. While the S&P 500 declined some 31% year-to-date and the Nasdaq declined 33%, solar stocks plunged even worse: STP -75%, TSL -73%, ESLR -69%, SPWRA -61%, CSIQ -56%, LDK -50% and FSLR -34%.

Congress passed a bill that approved about $18 billion of renewable-energy tax credits after repeated failed attempts to do so this year, and now there will be an administration that -- if it sticks to its claims -- will be more supportive of alternative energy. The only question investors should ask, so which do I pick?

"Renewable fuels and clean energy, a sector beaten down hard since last fall, are now primed for a major comeback," says Eric Roseman, editor of The Commodity Trend Alert. Here's his ETF play on the sector.

"With every passing day the price of crude oil rises, the secular trend to alternative energy becomes even more powerful. Consumers, companies and governments are now sick and tired of soaring energy prices.

"The long-term solution is to obviously reduce our dependence on oil and increase our consumption of renewable fuels like wind, solar, and nuclear energy.

"The bull market in alternative energy began in 2005 when a host of companies in this thriving sector went public, supported by government subsidies, especially in Germany and Spain. Interestingly, Germany and Spain have just reduced solar energy subsidies this spring.

"In my view, those subsidy cuts don't matter at this stage. When companies in the solar sector are making money, why should governments continue subsidizing them?

"For those who want to 'go green' there are new opportunities to tap the environmental trend by adding cutting edge, alternative energy ETFs to your portfolio," says Doug Fabian, editor of Successful Investing.

"ETF providers are starting to latch onto the green theme. Two fund families, PowerShares and Market Vectors, have created their own classes of clean energy ETFs. A pair of ETFs has been launched in the narrow but potentially profitable niche of solar energy.

"The Claymore/MAC Global Solar Energy Index ETF (NYSE: TAN) is designed to track 25 companies in the solar power industry. Sectors included in the ETF are equipment producers, companies that concentrate on selling electricity, and suppliers of materials or services, installation, integration or finance. TAN currently invests in companies such as MEMC Electronic Materials, Suntech Power Holdings, and LDK Solar Co. Ltd.

"Van Eck Global launched the Solar Energy ETF (ASE: KWT). That solar energy ETF seeks to replicate the price and yield performance of the Ardour Solar Energy Index, which includes companies that generate at least 66% of their revenues from solar energy. The four top holdings are First Solar, Germany's Q-Cells and Solarworld AG, and Norway's Renewable Energy.

LDK Solar Co. (NYSE: LDK) is one strange solar stock. Yesterday, on a day when other solar companies like Solarfun Power Holdings (NASDAQ: SOLF), Canadian Solar Inc (NASDAQ: CSIQ), First Solar Inc (NASDAQ: FSLR) and JA Solar Holdings (NASDAQ: JASO) were all strong and despite earnings coming in at the high end of expectations and guidance solidly ahead of estimates, their stock was down. Not only was it down, but it also tried rebounding, only to fail. Not good at all for the bull case.

Experience has taught me to respect the price action the day after earnings. So when I see LDK trying to break out of a now 5-month old range, pretty much between $30 and $40 -- yes it was up to $50 in January and $20 in March, but those are outliers -- this is a very bearish sign. It's so bearish that I suspect that unless solar plays really heat up again, this stock will need many more weeks or months to break $40, and even then, it's got a ton of resistance all over the place due to bitter buyers in at much higher prices who will be looking to cut their losses.

For 25 years, Steven Halpern, editor of TheStockAdvisors.com, has surveyed the leading financial newsletter advisors asking for their favorite stocks for the coming year. This article is one of 100+ ideas in the Best Stocks for 2008 report.

"First Solar (NASDAQ: FSLR) is my favorite speculative idea for 2008," says relative strength technician Dan Sullivan, editor of The Chartist.

"First Solar is the fastest growing manufacturer of solar modules in the world. And that's just the beginning. The company manufactures solar modules with an advanced thin film semiconductor process that significantly lowers solar electricity costs.

"Offering clean renewable electricity at affordable prices enables First Solar to provide an economic alternative to peak conventional electricity and fossil fuels.

"The solar module maker recorded a significant increase in revenue, easily beating Wall Street estimates. The company earned $46 million, or 58 cents per share, compared with $4.3 million, or 7 cents per share in the year-ago period.

"Our favorite speculative play for 2008 is First Solar (NASDAQ: FSLR)," says Bernie Schaeffer, editor of Schaeffer's Investment Research.

"First Solar is a specialized semiconductor company that is a play on the alternative-energy theme. FSLR designs, manufactures and sells solar electric power modules. With a price-earnings (P/E) ratio of 178 and the stock posting gains of nearly 700% in 2007, investors in FSLR should expect a potentially wild ride.

"Despite the 'internet bubble-like' appreciation in the stock, we think the trend can continue, as this is a company with actual earnings and its share of naysayers. The skepticism is an indication that there is sideline buying power that can drive the equity even higher in the months to come.

"FSLR's third-quarter earnings report was spectacular. Net income of 58 cents per share easily topped Wall Street's estimate of 19 cents per share, sending the stock soaring on the news. The year-over-year earnings growth rate in the third quarter was an outstanding 729%.

"Alternative energies are not just a pie-in-the-sky dream," says Paul Tracy and Nathan Slaughter from the StreetAuthority Market Advisor. "Denmark generates as much as 30% of its power from wind, Iceland uses geothermal energy, and producers are bringing down the cost of solar power."

"Overall, companies involved in alternative power technologies, such as wind, solar, geothermal, and biomass, are getting plenty of attention from investors these days." Here, the advisors profile what they consider to the most attractive companies in the alternative energy space.

Suntech Power Holdings Co. (NYSE: STP), "which manufactures and sells photovoltaic (PV) solar cells, has two primary advantages: a low manufacturing cost base and highly efficient cells.

"For starters, Suntech is based in China, where labor costs (even for skilled research staff) are far lower than in the Western world. The Chinese government also subsidizes such research, further helping companies like Suntech.

"In addition, the firm's cells boast some of the highest conversion rates on the market, allowing the company to offer smaller panels that can produce as much electricity as far larger ones from competitors.

"Suntech has been ramping up its manufacturing capacity rapidly in recent years to keep pace with strong demand. Analysts are forecasting robust earnings growth of 45% annually over the next five years.

"Germany is the third largest economy in the world, and it's leading index -- the DAX 30 -- has been in a bull market for four years," notes Heiko Böhmer.

The editor of Privat-Finanzletter offers a trio of German stocks -- on sports cars, solar cells, and Internet broadband growth -- as well as an ETF play for U.S. investors seeking an easy way to participate in the German market.

He explains, "Changes are occurring, as Angela Merkel has become the first female chancellor in Germany and the first chancellor from the former GDR. Meanwhile, we are seeing an ongoing consumer record, health care reform, corporate tax reform, and a recovering construction sector.

"Earnings growth for 2006 was estimated at 21%. I would caution, however, that earnings could slow this year and, after a four-year bull market, there is a chance for an overall market correction -- perhaps as much as 15%.

"Meanwhile, Germany is the biggest export nation in the world and is known for brands that are recognized worldwide. For example, Porsche (Other OTC:PSEPF) is the most profitable car producer. Earnings grew 78% from 2005 to 2006. The U.S. is a very important market.

"Meanwhile, its stake in Volkswagen could grow later this year. Currently, VW's earnings are the biggest driver for Porsche shares right now. Longer term, Porsche will be selling more higher margin cars such as the 911 Turbo. And, its Panamera will be launched in 2009-2010.
