Wave Energy Wave Power Clean Renewable Electricity Generation - Wavegen - 1 views

  • Ocean waves are a tertiary form of solar energy, in that unequal heating of the Earth’s surface generates wind, and wind blowing over water generates waves. Despite the fact that nearly 75% of the Earth’s surface is covered with water, waves are a largely unexplored source of energy, compared with the progress that has been made in harnessing the sun and wind.

Solar Power - Advantages and Disadvantages - Sustainable Development Information - 0 views

  • By converting the power of the sun into electricity, solar energy is clean, green, will never run out and, after the initial cost of the solar panels, is entirely free
  • The sun is constant – it will always be there and is therefore a reliable, utterly renewable source of energy.
  • As it does not rely on the burning of harmful fuels to generate electricity, solar power is non-polluting – it does not contribute to global warming or greenhouse gas emissions.

  • Solar energy is an infinitely renewable resource that uses the sun's rays to generate electricity for use in your home. By going solar, you can reduce your energy costs and lower your dependence on fossil fuels, thereby making your own contribution to a cleaner environment. Generally, the solar energy systems we use work as follows:

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."

    World biofuels production declined by 0.4% in 2012, the first decline since 2000. Increased output in South America and Asia Pacific was outweighed by declines in North America and Europe. Global ethanol output declined by 1.7%, the second straight annual decline. Biodiesel production grew by 2.7% and has doubled in the last five years and now makes up 31% of total biofuel supply.

Why is solar energy good for the planet - 0 views

  • Solar energy is good for the planet because it is a clean way to produce things we need every day. It doesnt cause pollution because it is nature's own energy and is a 100% renewable resource.

Geothermal Electricity Production - Geothermal Energy - Renewable Energy World - 0 views

  •  
    " Geothermal Electricity Production Most power plants need steam to generate electricity. The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface. There are three types of geothermal power plants: dry steam, flash steam, and binary cycle. Dry steam power plants draw from underground resources of steam. The steam is piped directly from underground wells to the power plant, where it is directed into a turbine/generator unit. There are only two known underground resources of steam in the United States: The Geysers in northern California and Yellowstone National Park in Wyoming, where there's a well-known geyser called Old Faithful. Since Yellowstone is protected from development, the only dry steam plants in the country are at The Geysers. This geothermal power plant generates electricity for the Imperial Valley in California. Credit: Warren Gretz Flash steam power plants are the most common. They use geothermal reservoirs of water with temperatures greater than 360°F (182°C). This very hot water flows up through wells in the ground under its own pressure. As it flows upward, the pressure decreases and some of the hot water boils into steam. The steam is then separated from the water and used to power a turbine/generator. Any leftover water and condensed steam are injected back into the reservoir, making this a sustainable resource. Binary cycle power plants operate on water at lower temperatures of about 225°-360°F (107°-182°C). These plants use the heat from the hot water to boil a working fluid, usually an organic compound with a low boiling point. The working fluid is vaporized in a heat exchanger and used to turn a turbine. The water is then injected back into the ground to be reheated. The water and the working fluid are

Geothermal energy in the United States - Wikipedia, the free encyclopedia - 0 views

  •  
    "eothermal energy in the United States continues to be an area of considerable activity. In 2012, the United States led the world in geothermal electricity production with 3,386 megawatts (MW) of installed capacity;[1][2] the largest group of geothermal power plants in the world is located at The Geysers, a geothermal field in California.[3] The United States generates an average of 15 billion kilowatt hours of geothermal power per year, comparable to burning some 25 million barrels (4,000,000 m3) of oil or 6 million short tons of coal per year.[4] Geothermal power plants are largely concentrated in the western states. They are the fourth largest source of renewable electricity, after hydroelectricity, biomass, and wind power. A geothermal resource assessment shows that nine western states together have the potential to provide over 20 percent of national electricity needs.[4][5]"

Hydrogen Fuel-Cell Vehicles - Is Hydrogen the Fuel of the Future? - 1 views

  • The benefits of ditching fossil fuels for hydrogen are many, of course. Burning fossil fuels like coal, natural gas and oil to heat and cool our buildings and run our vehicles takes a heavy toll on the environment, contributing significantly to both local problems such as elevated particulate levels and global ones such as a warming climate. The only by-product of running a hydrogen-powered fuel cell is oxygen and a trickle of water, neither of which will cause any harm to human health or the environment.
  • But right now, 95 percent of the hydrogen available in the United States is either extracted from fossil fuels or made using electrolytic processes powered by fossil fuels, thus negating any real emissions savings or reduction in fossil-fuel usage. Only if renewable energy sources—solar, wind and others—can be harnessed to provide the energy to process hydrogen fuel can the dream of a truly clean hydrogen fuel be realized.
  • They concluded that we’d lower greenhouse gas emissions more by driving gasoline/electric hybrid cars than by driving fuel-cell cars run on hydrogen from coal. Hydrogen made using natural gas would fare a little bit better in terms of pollution output, while making it from wind power would be a slam-dunk for the environment.

  • replacing the fossil fuels responsible for global warming and various nagging forms of pollution.

Information about Biofuel, what is Biofuel, renewable energy solutions, Ethanol uses - 0 views

  • Basically biofuel is produced by using ethanol from naturally grown plant matter which allows for a more sustainable and environmentally friendly earth.
  • Bio fuel is a natural alternative from other fossil fuels and is attained from living or biological material that has just died. Basically biofuel is produced by using ethanol from naturally grown plant matter which allows for a more sustainable and environmentally friendly earth. To assist in the manufacturing of biofuel, the plants and plant-derived materials that contribute to its formation includes corn, corn cob, sugar cane, soybeans, flaxseed, rapeseed, vegetable oils, waste cooking oils, animal fats, tall oil and even cow manure. However, at present the most widely used source of bioeenergy is of course wood.
