Myths And Facts About Solar Energy | Research | Media Matters for America - 0 views

  • solar energy exhibits the "fastest growth," providing "more than 10% of global electricity by 2050." The IEA further found that in high renewable scenarios, solar is essential due to its "almost unlimited potential":
  • At the American Enterprise Institute's blog, Kenneth Green promoted a press release claimIng that "Solar cells do not offset greenhouse gases" because solar cell production emits gases that "make carbon dioxide (CO2) seem harmless."

Towards a Just and Sustainable Solar industry - Silicon Valley Toxics Coalition - 0 views

  • Although solar panels provide clean energy while in use, a variety of factors during the manufacturing and disposal of these panels have the potential to greatly damage the environment.
  • The most commonly used solar panels are silicon-based panels that share many of the same materials and manufacturing processes as semiconductors. Solar panels have the potential to create an e-waste burden if the proper infrastructure is not developed before the first wave of panels begins to come down.

Getting to Solar Energy Sustainability | The Energy Collective - 2 views

  • I recognize this may seem like fantasy, but if the proponents of solar energy and other clean energy alternatives really want it to succeed they must get off life support, be free from the addiction to unsustainable subsidies, and given a chance to grow and thrive on their own in a healthy, competitive market environment where innovation and hard work create sustainable market equilibrium.

Where Does Wind Power Come From? - 0 views

  •  Wind power is an interesting renewable energy source as wind turbines can essentially be placed anywhere geographically where there is ample wind to turn the wind blades.
  • One thing that we haven't written about extensively on the MyEnergySolution.com blog is wind power.  Wind power is an interesting renewable energy source as wind turbines can essentially be placed anywhere geographically where there is ample wind to turn the wind blades.
  • o put this in context, an average U.S. household uses about 10 megawatt-hours (MWh) of electricity each year. One megawatt of installed wind energy from a single large turbine can generate from 2,400 to more than 3,000 MWh annually – enough to power about 250 homes.

How much CO2 does solar energy produce? | Ecooutfitters.net - 0 views

  • Let’s not hide the fact that manufacturing solar panels requires resources, fossil fuels that release CO2 emissions and add to our carbon footprint. However, it’s been shown in numerous studies that solar panel production releases nowhere near as much CO2 and other greenhouse gases as electric generated from coal, oil, natural gas, etc. (And you still need to produce the equipment to generate electricity from those sources as well.)

U.S. Takes Global Lead in Wind Energy Production | LiveScience - 1 views

  • During the first half of 2008, the United States, for the first time, generated more wind energy electricity than Germany, despite the fact that the smaller European country still has more turbines than we do. Germany has enough turbines to collect about 22,000 to 23,000 megawatts of power, while the United States has a capacity of about 18,000 megawatts,

Wind Power - 0 views

  • We have been harnessing the wind's energy for hundreds of years. From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent - a wind turbine - can use the wind's energy to generate electricity.
  • Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor.
  • A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity.

  • Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant. Several electricity providers today use wind plants to supply power to their customers.

  •  
    Written by Michael Parfit Republished from the pages of National Geographic magazine Freedom! I stand in a cluttered room surrounded by the debris of electrical enthusiasm: wire peelings, snippets of copper, yellow connectors, insulated pliers. For me these are the tools of freedom. I have just installed a dozen solar panels on my roof, and they work.

Wind Power: A Lucrative Renewable Energy Source - 0 views

  •  
    There are many renewable energy sources out there right now, continuing to develop in their technology and production. All of these resources have very high capital cost inputs that are hard to compete with cheap natural gas. However, these new resources are abundant, some even limitless, and unlike natural gas, fuels and oil, they will be around for a long time.

reich-chemistry - Donovan.Norberg.Fall.2010 - 0 views

  • Biodiesel is a type of bio-fuel which is used to fuel cars and other vehicles. Biodiesel is used as alternative petroleum oil. Biodiesel is special because it is a clean resource and is safe to use in our environment, compared to other fuels that pollute the planet. Biodiesel is made from renewable resources which make it easier to produce. Biodiesel also lubricates car engines, which decreases engine wear, making the engine last longer. Speaking of engines, biodiesel is compatible with most car engines that run on diesel. According to researchers, biodiesel can reduce the risk of cancer, which the emitting of petroleum oil have been known to cause.

  • Fatty acid methyl esters (FAME), known as biodiesel, are products of plant or animal origin whose composition and properties are defined by the European Union in standard EN 14214. There is an exception for the iodine value for Spain, which has been established as 140 rather than the 120 proposed by standard EN 14214.
