How Does a Wind Turbine Work
How Do These Wind Turbines Work You May Ask, We Will Try To Answer That Here
What are Wind Turbines
Modern wind turbines are essentially much like a wind mill, much like the one’s you’d see on farms or in Holland. However, instead of being attached to a mill to grind grain into flour, the turbine is attached to an electrical generator. The result is energy. How much energy? Well it depends on the size of the blades and the wind speed.
Wind turbines can be used on a large scale to produce energy for a city. The turbines generally have two or three blades or rotors. On sunny, windy days they can produce several megawatts. The energy can also be stored for non windy days. On a smaller scale, for home use, a wind turbine can produce about 100 kilowatts. They work well to compliment a solar electric power system.

Electric Car Batteries Lithium Ion Batteries Breakthrough Electric Car Range Tripled
Electric Car Batteries Lithium Ion Batteries Breakthrough Electric Car Range Tripled
Building on the existing award-winning Argonne-Envia collaboration, the Argonne license contributed complementary technology to Envia’s development of industry-leading lithium-ion battery solutions. General Motors also invested $7 million in Envia to provide its “battery engineering team with access to advanced lithium-ion cathode technology that delivers higher cell energy density and lower cost.” Other Envia Investors include Asahi Kasei and Asahi Glass, Bay Partners, Redpoint and Panagea Ventures totaling $17 million.
Advanced Research Project Agency•Energy, or ARPA•E gave them a $4 million dollar award grant to help with the research as well. The whole idea of ARPA•E was:
To bring a freshness, excitement, and sense of mission to energy research that will attract many of the U.S.’s best and brightest minds—those of experienced scientists and engineers, and, especially, those of students and young researchers, including persons in the entrepreneurial world.

Renewable Energy Policy Important to Future of Planet
Renewable Energy Policy Important to Future of Planet, but more importantly, to mankind's future
Most recently, at Obama’s 2012 State of the Union Address Energy, he laid out a half dozen energy proposals, however, most of the policies he announced were either previously announced, stand little chance of passing through congress, or not that big of a deal. According to Jose Valera, a Houston based lawyer in the energy practice at the global law firm Mayer Brown, “It’s a smart, well balanced, welcome policy, and everybody is a winner.”
While the traditional fossil fuels will still play an important role in the future while we transition to renewables, in technologies like wind and solar, Obama called for extending tax credits that basically give these firms a 30% subsidy and also called for the federal government to allow renewable projects on its land.

Clean Energy Fuel What Are They?
Clean energy fuel definitions can greatly vary depending on who you ask
Methane (CH₄) is a primary component of natural gas and a highly potent greenhouse gas which can also be emitted into the air when the gas is not burned properly and completely. Similarly, methane can be emitted as the result of leaks and losses during transportation. Emissions of sulfur dioxide and mercury compounds from burning natural gas are negligible.
Methane remains in the atmosphere for approximately 9-15 years and is 25 times more effective in trapping heat in the atmosphere than carbon dioxide (CO₂) over a 100-year period and 72 times more potent over a 20 year period. It is emitted from a variety of natural and human-influenced sources. The human-influenced sources include landfills, natural gas and petroleum systems, agricultural activities, coal mining, stationary and mobile combustion, waste-water treatment, and certain industrial processes.

Offshore Wind Power Important to Future of Clean Energy Development
Offshore Wind Power Important to Future of Clean Energy Development Like This Horns Rev from DONG Energy in Denmark
The problem with these projects is that they tend to be expensive, costing roughly 2.5 to 3.0 million Euro/MW. The turbines themselves represent only a third to one half of the total costs in the projects today while the rest of the costs come from the infrastructure required, maintenance and oversight of the projects. In 2011, Danish energy company DONG Energy made a claim that these types of projects aren’t yet competitive with fossil fuels, however they estimate that they will be in 15 years. Until that point is reached, government funding, subsidies and other incentives will be required to make the projects more economically feasible. Taking that into account, we still heavily subsidize the fossil fuel industry so why not shift some of that funding over to these types of projects?
