For some innovations, such as calculators and computers, the key to success was in finding a way to make things smaller. The future of concentrated solar power, on the other hand, depends on making the product deliverable on a grand scale.
The American Wind Energy Association (AWEA) reported the U.S. market for small wind turbines with 100 kilowatts (kW) capacity or less grew 78 percent in 2008, with a total of 17.3 megawatts (MW) of new installed capacity, offering evidence that consumer demand for clean energy options is rising.
A plan proposed by Souther California Edison (SCE) for the largest U.S. installation of advanced solar panels on otherwise unused large commercial rooftops across Southern California was approved by the California Public Utilities Commission.
New flexible solar cell technology developed by a group of engineering researchers at McMaster University, Hamilton, Ontario, has been installed at a bus shelter on campus to power lighting for nighttime transit users.
Harnessing and coordinating the power of wind, solar and battery storage and smoothly integrating these resources with the grid is a formidable technical challenge, but it is crucial to America’s future of mixed-source renewable energy.
Wind power may have the potential to drastically alter our nation’s electricity consumption and reduce harmful emissions of greenhouse gases, but it will be of little use to energy consumers if the power generated can’t travel easily from the turbine to the plug.
With all of the talk in government circles about the possibilities of renewable power, it makes sense that the focus should be on developing those resources in the nation’s Western states, where the potential is arguably the greatest.
The United States officially joined the International Renewable Energy Agency (IRENA) on June 29, 2009, increasing the number of countries participating in the organization to 136. IRENA was initially founded on Jan.
President Obama has made no secret about the role he sees for renewable power in the nation’s energy future. To his credit, his administration has backed up words with a sizable investment of stimulus funds.
In April, Madison County, Ind., commissioners adopted an ordinance amending the County’s Land Use and Development Code with regulations for the development of wind farms. The ordinance sets standards for such issues as setbacks, height, access and safety. Tax issues also were addressed.
Air Burners LLC introduced a portable wood-waste burner that produces up to 350 kilowatts of electricity, claiming it is enough to support more than 30 homes. The machine is based on the Palm City, Fla.-based company’s wood-waste disposal systems. The U.S.
The new green economy is expected to decrease the billions of dollars spent each year on foreign oil, reduce carbon emissions and create millions of new jobs for Americans. While solar energy is promising, wind energy is booming.
Texas is known for doing things big. In this case, a first-of-its-kind application for generating solar electricity by covering a solid waste landfill with a flexible membrane containing photovoltaic (PV) cells.
Researchers have developed a technique that uses sensors and computational software to constantly monitor forces exerted on wind turbine blades, a step toward improving efficiency by adjusting for rapidly changing wind conditions.
Forget solar, wind and biomass. According to many experts, the way to save the planet, create green jobs, and sever the country’s ties to foreign oil is not through groundbreaking, innovative use of renewable power. They say it has nothing to do with generating any power at all.
Anyone who has ever played in the surf knows the crushing power of waves, and many have schemed of ways to harness that energy and convert it into electricity. Thomas Edison and Alexander Graham Bell both toyed with the notion.
Renewable power sounds good on paper, but for many, it is only something to pontificate about. In reality, for individuals, families and small businesses, switching to renewable power often is not a practical or cost-effective alternative.
