New York - Algeria looks to develop solar energy as an export resource, knowing that its reserves of oil and natural gas will one day dry up.
It was an idea being considered by Algerian planners for years but now work has begun on the construction of its first solar power plant at Hassi R'mel, 260 miles south of Algiers, the capital. The solar plant will be a hybrid, using both sun and natural gas to generate 150 megawatts. Of that, 25 megawatts will come from giant parabolic mirrors stretching over nearly 2 million square feet, which is roughly the size of 45 football fields.
The solar hybrid plant is the first of its kind and is expected to be online by 2010. In the future, Algeria hopes to generate enough solar power that it can export 6,000 megawatts to the European market by 2020, which would be equal to a tenth of current electricity consumption in Germany.

While the concept on a large scale is grand, critics are concerned that the huge number of mirrors will produce more heat which could reflect into the lower atmosphere and raise the global temperature, not unlike how cities with their massive amounts of concrete and asphalt absorb heat and return it to the atmosphere which raises the average temperature there. But Algerian representatives closer to the project say that's nonsense due to the location, which does not site directly by populated areas.
"Our potential in thermal solar power is four times the world's energy consumption so you can have all the ambitions you want with that," said Tewfik Hasni, managing director of New Energy Algeria, or NEAL, a company created by the Algerian government in 2002 to develop renewable energy.
Hasni says that it will take 10 years for it to become economically competitive, and while undersea cables to Sicily and Spain are planned for construction in 2010-2012, financing has not been worked out. But after the EU set lofty goals this year of producing 20% of its energy consumption from renewable sources by 2020, by the time the Alegerian solar project goes online, political difficulties could be set aside which would permit the next phase of construction to move forward - transmission to the European market.
Algeria's move to join the alternative energy camp is one other OPEC members have resisted, though they've all closely watched technology developments.
One of the supporters of Algeria's hybrid solar project is French President Nicolas Sarkozy who has said that it would "bind France and Algeria" in creating his vision of a "Mediteranian Union", giving rise to France's possible financing of the underseas transmission cable.
While OPEC nations have tried to curb talk of altnerative energy, with global concerns over limited oil supplies and the growing threat of global warming from fossil fuels, many OPEC members are now becoming more open to the idea.
Eduardo Zarza Moya, who works on solar power for Spain's public energy research center, CIEMAT, said at a June solar conference in Algeria, "The solar potential of Algeria is huge, enormous, because solar radiation is high and there is plenty of land for solar plants."
Also attending the conference was Wolfgang Palz, chairman of the independent World Council for Renewable Energy, who said that this was a big chance for OPEC member countries to "really do something instead of torpedoing alternative energy development."
The Hassi R'Mel plant is one of four planned for construction. Its use of abundent natural gas supplies are intended to suplement times of overcast skies, which could reduce solar power generation levels and for use at night when the sun

Toward a greener economy
By Moises Velasquez-Manoff
New York - Market bubbles occur when goods are traded at prices that greatly exceed real value. They burst when they grow so bloated that they become unstable. The current economic turmoil, widely viewed as the worst since 1929, is one example of what can happen when the difference between market value and actual value becomes too great.
Environmentally minded economists have long warned that equally burstable ecological bubbles can occur if humanity lives beyond earth's capacity to regenerate. The problem, they say, is that we're addicted to economic growth. Mainstream economics assumes that the economy, the engine of modern civilization, can grow perpetually.

For almost as long as people have worried about global warming, economists have called for taxing carbon emissions. As long as sending CO2 skyward was cost-free, they argued, the practice would continue.
Starting Sept. 25, for the first time in US history, a price tag will begin to be placed on millions of tons of carbon dioxide spewing from every major power plant from Maine to Maryland.
Just what that price will be won't be known until after Thursday's computerized auction of about 12.5 million tons of "carbon allowances," essentially permission slips to pollute.
Utility companies will bid on the allowances. They may be used, saved, or traded so that any company with a need to send more CO2 up the stack can buy more - at the market price. The amount of CO2 to be cut over the next decade is modest - about 18 million tons annually (US power plants collectively emit about 2.8 billion tons of CO2 yearly). But the auction and process of setting a price for carbon are critical first steps, many say.

Dispelling The “Twisted Truths” Of Energy-Saving Light Bulbs
For more than 129 years, people have used the incandescent light bulb as the primary light source for the home. With more consumers searching for products that are good for the environment, a new light bulb is revolutionizing lighting around the world. Energy-saving compact fluorescent light bulbs (CFLs) have become the symbol of the “green” movement. They use 75 percent less energy and last as much as 10 times longer than traditional incandescent light bulbs. Plus, they help reduce carbon dioxide emissions linked to global warming.

Campaign Plants Trees At Schools Across The U.S.
Schools are generally seen as the place to plant the seeds of knowledge. Yet thanks to a one-day environmental campaign, schools and parks across the country became places to plant something a little greener.
Sixteen schools across the country, from Long Island to Hawaii, participated in the initial “Trees for Success” campaign, with more than 800 trees planted in schools and neighboring parks in a single day. The schools were selected by the Arbor Day Foundation out of more than 200 applications based on need, civic and local support, student involvement, a plan for upkeep, and location.

Wind Power Is Poised To Support U.S. Jobs
The U.S. Department of Energy contends that wind power can provide 20 percent of the nation’s electricity by 2030.
Experts say there is a renewable source of energy that is capable of becoming a major contributor to America’s electricity supply over the next three decades--wind power.
In 2007, wind was already one of the fastest-growing sources of electricity in U.S. households, and the U.S. Department of Energy contends that wind power can provide 20 percent of the nation’s electricity by 2030 and be a critical part of the solution to global warming.

Algae-To-Energy Tests Planned
AEN News
For decades, scientists and energy executives have sought to unlock the energy potential of algae. Best known as the green pond scum that befouls rivers, lakes and streams, the single-celled plants are also a potentially prolific source of renewable fuels that could be used to power engines in cars, trucks, generators and many other machines.
Because algae use carbon dioxide to grow and reproduce, releasing oxygen in the process, systems that use them to produce renewable biofuel supplies are also being eyed for their promise in reducing carbon dioxide emissions from power plants and other sources generally believed to promote global warming.
Despite the promise of this approach in a world searching for renewable alternatives to limited fossil fuel supplies, attempts to develop algae-derived biofuels in commercially viable volumes have not been successful.
Now, that could be changing.
