Did you know that America’s largest installed solar power plant is located on Nellis Air Force Base in Nevada? The 14-megawatt solar array (shown at left) went live in late 2007 and remains the largest solar power plant in the United States.

While First Solar’s recent announcement of two 250-megawatt solar power plants in California dwarfs the military’s solar array, the fact remains that for a considerable amount of time the military will have operated the largest solar array in the United States. Why would the military take this step? The answer is energy security.

In spite of the Pacific Northwest’s reputation for environmental leadership, short-sighted opponents of hydroelectric power struck a blow last week when Oregon-based utility PacifiCorp agreed — under duress — to decommission a series of hydroelectric dams in the Upper Klamath River along the Oregon-California border.

Power from the dams is used to serve electrical load in Oregon and Northern California. Without the dams in operation (the licenses were extended to 2020 when they are to be shut down) PacifiCorp will have to find a way to replace the renewable, emissions-free energy that the dams provided.

Regulators were joined by dam protestors in contending that the quest for new power can be done in a way that does not damage the environment anymore or put too much of a dent in consumers’ pockets. And things are certainly expected to go swimmingly for the salmon populations that the dams threatened.

The European Union will unveil a proposal this week calling for $73 billion (50 billion euros) in research over the next decade into improving wind, solar, and nuclear power technologies, as well as the development of carbon capture and sequestration projects and energy-efficient “Smart Cities.”

The report, prepared by the European Union’s executive body, the European Commission, says the surge in investment is necessary if Europe hopes to meet its goal of slashing greenhouse gas emissions by 80 percent by 2050.

Like many Americans who don’t realize that every time you flip the switch on a television or light, it results in the burning of coal or natural gas at a power plant, Britney Spears does not prioritize the use of energy in her life.

Why? A) She is crazy, B) Like so many others she doesn’t recognize that she personally is responsible for the pollution that is generated through her energy use, or C) All of the above.

If you answered A or C, shame on you. Similar to you or myself, without recognizing that she has a problem, it wouldn’t occur to Britney to change her behavior.

With the recent surge in money going towards renewable energy research and implementation, many people are forgetting a key factor in reducing our impact on the environment: energy efficiency.

Utilizing renewable energy in your home or commercial building is great, don’t get me wrong, but before this expensive option is employed, you should first look at the efficiency of your home or building’s energy systems.

If your building wastes energy, you should prioritize improving this aspect and use the money that you had set aside for a renewable project to accomplish the task.

Biofuels offer a unique opportunity for the developing world. Almost 80 percent of the remaining land that has cultivation potential resides in South America and Africa, according to research supported by the United Nations.

However, without a standard method for determining the impact of biofuels on the environment, international bodies like the U.N. will tread carefully when discussing the role of bioenergy in mitigating the effects of climate change, despite the potential economic benefits for the developing world.

The future of bioenergy from algae and bioengineered feedstocks is an exciting and promising opportunity for life science to take a larger role in sustaining our energy needs.

Some heavyweights who know a thing or two about transportation are having a pointed online debate about whether or not electric vehicles should receive support from the federal government.

Terry Tamminen, who was Secretary of the California Environmental Protection Agency under Republican Governor Arnold Schwarzenegger, threw down the gauntlet last month in an editorial in which he stated that “it’s time to dump the battery-powered car in the same policy landfill as corn-based ethanol.”

What lessons can California learn from Sweden’s successes in sustainable innovation? What are the California’s energy and environmental goals, and what progress has been made to reach them?

The 2009 Sustainable Innovation Event, presented by the Swedish-American Chamber of Commerce San Francisco/Silicon Valley, will discuss these questions and more Monday, Oct. 5 in South San Francisco.

Readers of CleanTechies, a media partner for this event, can attend for a discount price of $55.00 (regular $65).

Since 2007, the French photovoltaic market has been booming, with close to 500 megawatts of installed capacity expected this year, up from a mere 40 megawatts three years ago.

Most of this growth first stemmed from residential installations that benefited from high feed-in-tariffs for producers and substantial tax rebates for households. Since last year larger installations have also been skyrocketing.

On September 14, the French government released a draft regulation detailing the upcoming changes regarding photovoltaic electricity feed-in-tariffs in France. This draft is pending approval from the Conseil Supérieur de l’Energie (Energy Supreme Council) until late September.

An amazingly high percentage of people who live down the Mid-Atlantic Seaboard from New York to Virginia want wind turbines off their coast.

Even if they can be seen from the shoreline, 67 percent support off-shore wind power, according to a new  poll of coastal residents of New York, New Jersey, Delaware, Maryland, and Virginia .

If the turbines are out of sight, the level of support goes up to an astounding 82 percent.
