"The way to win in solar is to invest in the industry leaders and SunTech Power Holdings Ltd. (NYSE: STP) is a big as they come," says growth expert Toby Smith in his ChangeWave Investing.

"China will surpass the US as the world's largest market for wind turbines -- after doubling wind power capacity in each of the last four years.

"Chinese government mandates for cleaner energy are a big factor driving the blossoming wind and solar projects, but other forces are at work, too. Chinese power companies are loaded with cash and state-owned banks are eager to lend them more money.

When Charles Dickens wrote, "Bring in the bottled lightning, a clean tumbler and a corkscrew," it's safe to say the great English novelist wasn't referring to energy technology. But in the 21st century we know that a whole lot of bottled lightning can be uncorked using a variety of sophisticated devices -- and one of the most interesting types is fuel cells.

Today we got lightning news from one of the best companies in the fuel cell space, the aptly named FuelCell Energy (NASDAQ: FCEL). Although the company reported lower product sales and revenues for fiscal Q2 of $19.3 million compared to $26.4 million in fiscal Q2 a year ago, it did say that the prior year product sales and revenues were unusually high due to timing.

"It's no secret that the world is facing a severe water shortage; many experts, believe the next major war will be fought over water, not oil," says Marc Lichtenfeld.

The senior equity analyst for the top-notch growth stock advisory, Xcelerated Profits Report explains, "Desalination is likely the only way the world's water needs will be met. And one company that will benefit is Energy Recovery (NASDAQ: ERII).

"Just how severe is the shortage? Demand for fresh water will exceed supply by 50% in 2025, with one-third of the Earth's population living in countries with water scarcity. The bottom line is that if we plan to feed and provide water for everyone, we're going to have to find a way to use more water more efficiently.

What sectors are poised to outperform as a result of a Barack Obama presidency? To find out, we turn to fund expert Jim Lowell who recent prepared a report highlighting the top ETFs based on each candidate.

In The Forbes ETF Trader, he offers several top picks including ETFs that are focused on biotechnology and medical research, industrials, clean environment and clean energy technologies.

"SPDR Biotech (ASE: XBI) seeks investment results that correspond to the price and yield performance of the S&P Biotechnology Select Industry Index which is made up of the biotechnology sector of the S&P Total Markets Index.

"Vanguard Industrials (NYSE: VIS) seeks investment results that correspond to the price and yield performance of the Morgan Stanley Capital International US Investable Market Industrials Index.

"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.

"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?

"Suntech Power Holdings (NYSE: STP), one of our long-time favorites, is now back on our buy list after being driven down in price by U.S. market volatility and the fallout from a recent earnings report," notes Jim Trippon.

The editor of The China Stock Digest explains, The company is world leader in the manufacture of photovoltaic solar cells and solar electric systems. And, it is developing a new technology to increase solar efficiency." Here is his review.

"The company's solar cells are used to supply power to the electricity grid within China, and it's the number one company in the Chinese solar energy industry. The company's systems also provide dependable power internationally for mobile phone networks and telecommunications relay stations and even street lamps in case of power outages.

"Certainly China is in desperate need of clean renewable sources of energy. Residents of major cities like Beijing and Shanghai are constantly enveloped in a choking cloud of smog. Beijing has said it wants a tenth of its energy to come from environmentally friendly sources by 2010.

"The problem with solar energy has always been the high cost of manufacturing solar cells relative to the amount of power output per cell. Suntech is attacking that problem with rigorous cost control and the competitive advantages that low cost Chinese manufacturers enjoy in the international arena.

I've just returned from the World Money Show in Orlando where more than 10,000 investors gathered to learn about global investing. I had a chance to meet with many of the U.S. and foreign financial experts featured at the show, and over the next week I will share some of their top investment ideas.

As an advisor, scientist, and venture capitalist, Josh Wolfe is a recognized leader in nanotechnology; in fact, he was among a handful of industry experts invited to join President Bush in the Oval Office when he signed the landmark nanotech funding bill.

The ideas that he recommends are often meant for the more-sophisticated investor, as can be seen from his latest global nanotech idea -- Oxonica (LSE:OXN), a London-listed nanotech firm. Intriguingly, he speculates that the company may soon list its shares in the U.S.

The editor of The Forbes/Wolfe Nanotech Report explains, "Oxonica, which supplies nanomaterials for the energy, security, health care, and materials sectors, appears to be bucking the trend. Spun out of Oxford University in 1999, Oxonica has already established itself as a leading nanotech start-up.

"Recently, it was rated as a top start-up for corporate partnership by nanotech strategic advisory firm Lux Research." For full disclosure, he notes that his venture firm Lux Capital is an equity investor in Lux Research.

Meanwhile, he notes, "The key to Oxonica's success has been its portfolio management approach to commercializing nanomaterials. Oxonica has products in its pipeline for industries as diverse as cosmetics, energy, security, and bio-diagnostics and it has not restricted itself to being a one-trick pony.
