Reflective dishes may be the answer to make solar energy competitive with conventional sources of power, Israeli scientists say.  A global race is on to find energy alternatives as subsidies tip the balance in favour of renewable sources of power, which answer security and climate change concerns about fossil fuels. New-found demand for one such renewable source, solar energy, has sucked up supply of the silicon raw material, prompting a search for alternatives. A team at Israel’s Ben Gurion University believe they have found just that, in a far less known material that is more expensive than silicon but also more efficient when used with a reflective dish.

The clean energy homes of tomorrow are on display all this week on America’s Main Street, the national mall in Washington, D.C.- and they are generating excitement from the FORTUNE 500 companies, government advocates for renewable energy and even some venture capitalists. They are there as part of the U.S. Department of Energy’s Solar Decathlon, a contest in which 20 colleges vie to build energy-efficient, sustainable, attractive and affordable homes. The results can be eye-popping.

On hot, sunny days when air conditioners threaten to overload the power grid, solar power generation makes a lot of sense. Solar panels produce the most electricity exactly when demand peaks, so they reduce the load on conventional power plants at the right time. Solar panels also cleanly and quietly produce power exactly where it is consumed, so they help to prevent power outages caused by overloaded transmission lines.

Kilometre-sized solar panel arrays would gather sunlight in orbit, then beam it to Earth in the form of microwaves or a laser.

A futuristic scheme to collect solar energy on satellites and beam it to Earth has gained a large supporter in the US military. A report released yesterday by the National Security Space Office recommends that the US government sponsor projects to demonstrate solar-power-generating satellites and provide financial incentives for further private development of the technology.

One of the strongest group of stocks today, and one of my old favorites, is Solar Power Stocks!  I mentioned these many times earlier this year when they were among the market’s leaders. And I’m happy to report that they’re still among the leaders today! So I’m going to resume writing about them because I can’t think of a bigger market opportunity than the one these companies are addressing. (more…)

Photovoltaics – direct sunlight conversion into electricity using solar cells – has long been lumped with nuclear fusion as one of the great hopes for a boundless, clean energy future, although recent fusion interest has shifted to the more difficult ‘aneutronic’ version, which reduces fusion’s radioactive wastes but is even further in the future.  Unlike fusion, the technical viability of photovoltaics has long been established, with this occurring in applications requiring extremes of reliability and durability. Since the early 1960s, photovoltaics has been the main power source for space missions of any duration. Closer to home, it has been the standard power source for telecommunications in remote areas of Australia since the early 1980s. In the same timeframe, there was the view that the photovoltaics industry would grow steadily to a size where it would suddenly take off, as reducing prices opened up new market sectors. Wise heads debated how large a growth rate an emerging industry could sustain over a prolonged period, with a compounded rate of 25 per cent a year a consensus view.

Thermal-power plants that store heat for cloudy days could solve some of the problems with solar power.

Solar proponents love to boast that just a few hundred square kilometers’ worth of photovoltaic solar panels installed in Southwestern deserts could power the United States. Their schemes come with a caveat, of course: without backup power plants or expensive investments in giant batteries, flywheels, or other energy-storage systems, this solar-power supply would fluctuate wildly with each passing cloud (not to mention with the sun’s daily rise and fall and seasonal ebbs and flows). Solar-power startup Ausra, based in Palo Alto, thinks it has the solution: solar-thermal-power plants that turn sunlight into steam and efficiently store heat for cloudy days.

Large-scale manufacturing techniques used to build LCDs could make solar power far more competitive.

The big manufacturing equipment that has helped bring down costs for flat-screen TVs based on liquid-crystal-display (LCD) technology may soon bring prices for solar electricity more in line with prices for electricity from the grid. Applied Materials, a company based in Santa Clara, CA, that supplies manufacturing equipment to LCD makers, as well as to major microchip makers, has converted its equipment to produce thin-film silicon solar cells that are cheap enough to compete with more conventional solar cells. This may eventually lead to much cheaper solar power.

Solar energy-related stocks are hot. In the first half of 2007, there was a record $4.7 billion in capital raised in solar-based IPOs, according to U.K.-based research firm New Energy Finance. That’s more than double the amount raised in new solar issues during all of last year. Venture capital and private equity funding for solar firms reached new highs as well, totaling $1.4 billion in the 12 months ending June 2007. Much of this isn’t just pie-in-the sky financing. According to RBC Capital Markets, annual profits will reach approximately $7.7 billion in the solar sector this year and grow to $11.5 billion in 2011.

Ascent Solar Technologies Inc., a developer of thin-film photovoltaic materials, has obtained more funding from the U.S. Air Force Research Laboratory (AFRL). The goal is to increase the funding of Ascent Solar’s development of thin-film tandem photovoltaics (PV), based on monolithically integrated CIGS technology. The contract modification represents up to $749,000 of additional contract value over a 27-month period.
