  • 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.

solar solar power facts

shared by butlerlex99 on 12 Mar 13 - No Cached
  • For billions of years, the sun has poured out huge amounts of energy in several forms, including light, heat, radio waves, and even x-ray. The Earth, in orbit around the sun, intercepts a very small part of the sun’s immense output. On Earth, direct sunlight is available from sunrise until sunset, except during solar eclipses. Solar collectors and modules are designed to capture some of the sun’s energy and change it from radiation into more usable forms such as heat or electricity. In fact, sunlight is an excellent source of heat and electricity, the two most important forms of energy we consume.

  • Tidal turbines look like wind turbines. They are arrayed underwater in rows, as in some wind farms. The turbines function best where coastal currents run between 3.6 and 4.9 knots (4 and 5.5 mph).

  • The pattern of tides is extremely stable and not strongly affected by weather conditions which suggests that it would be a very stable source of green energy.
  • Moving water can exert a much greater force on a turbine than wind which means the turbine can turn slowly and still produce a great deal of electricity. The slow and stable tidal forces are ideal parameters for engineering energy solutions. The fact that the turbines can be slow-moving makes it easier to avoid interfering with local ecosystems

  • Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year. Solar energy is the technology used to harness the sun's energy and make it useable. Today, the technology produces less than one tenth of one percent of global energy demand.
  • In one technique, long troughs of U-shaped mirrors focus sunlight on a pipe of oil that runs through the middle. The hot oil then boils water for electricity generation. Another technique uses moveable mirrors to focus the sun's rays on a collector tower, where a receiver sits. Molten salt flowing through the receiver is heated to run a generator.
  • Despite the drawbacks, solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Japan, Germany, and the United States are major markets for solar cells. With tax incentives, solar electricity can often pay for itself in five to ten years.

  • Earth is composed mainly of bodies of water---about 71 percent of the earth's surface is water. Ninety-seven percent of that is found in the oceans. Because the earth's surface is curved, the sun heats it unevenly. This causes winds to blow across the water and generate waves. The sun and moon also exert their gravitational pull on the earth, triggering wave-producing tides. Wave motion energy can be harnessed and generated into electricity.

Fuel Cell history

shared by dpurdy on 15 Mar 12 - No Cached
  • Hydrogen is colorless, odorless, tasteless and non-toxic. It is a gas at temperatures above -423° F and is highly diffuse, having a density approximately 14 times less than that of air. Because it is buoyant and diffusive, hydrogen dissipates quickly in open areas and can move through small spaces, which makes it difficult to store. Hydrogen is flammable over a broad range of gas concentration (from 4 to 74 percent), although its lower flammability limit – that is, the lowest temperature and pressure at which it will combust – is higher than those for some common fuels such as gasoline, propane or diesel.1 Hydrogen has been described as “the fuel of the future.” On Earth, hydrogen is found in combination with other elements such as carbon (hydrocarbons), oxygen (water) and nitrogen (ammonia). Although hydrogen may sometimes be used as a fuel, it is most often used as an energy carrier, such as electricity, and not an energy source. To make hydrogen a usable, stand-alone fuel, it must be separated from these other elements by chemical, thermal or electrochemical processes.
  • History British scientist Henry Cavendish identified hydrogen as a distinct element in 1766. Subsequent experiments by British and French scientists resulted in the first flight of a hydrogen balloon and the discovery that applying electricity to water can produce hydrogen and oxygen.
  • In the 1960s, NASA space capsules used hydrogen fuel cells for onboard electric power, heat and water.

Renewable Solar Energy: How is Wind Formed - 0 views

  • Wind is formed by the indirect effect of the sun on the Earth’s surface. There is a reasonable explanation why is it so. As the sun shines, the Sun heats the Earth's surface; the air near ground level gets hot and rises up. Cold air at higher altitudes replaces it. At nighttime the process is reversed. This is  in principal how is wind formed on Earth.
  • This process of hot air rising and colder air sinking, causes high and low air pressure areas and results in wind formation. The more the pressure changes in an area, the faster the wind speed will be. If two areas are close to each other, pressure difference will cause higher wind speed to be produced compared to areas that are far apart from each other. This is how the wind is formed on Earth and this phenomena is known as vertical wind formation

  • Tidal energy use harnesses the water flow created primarily by the moon orbiting the Earth. As water is pulled toward the gravity of the moon, currents are created that can turn generator turbines.
  • Tidal energy use involving dams creates many of the same environmental concerns as damming rivers. Tidal dams restrict fish migration and cause silt build up which affects tidal basin ecosystems in negative ways. Systems that take advantage of natural narrow channels with high tidal flow rates have less negative environmental impact than dammed systems. But they are not without environmental problems. Both systems use turbines that can cause fish kills. But these are being replaced by new, more fish friendly turbines. The art and science of environmentally friendly hydro engineering is well advanced and will certainly be applied to any tidal energy project.
  • Because of intermittency and variable flow problems of tidal energy, it is a very limited resource. The DOE Tidal Energy link, above, states that there are only about 40 really good sites on Earth with high enough flows to be considered economically practical

  • Though our scientists may claim that they are inventing something new by using wind as a source of generating energy, the truth is that wind is being used for centuries for this purpose. An example of this is an article published in 1838, which clearly shows that even in those times, wind was considered an important source of energy. Here are a few quotes that were recorded in the past, which prove that wind was always important in generating energy
  • Renewable energy production and demand growth is gaining momentum in many ways across the world. There is a booming demand of wind power today and all wind energy equipment manufacturers are gearing up to meet the demand and take advantage of it. Wind power capacity growth will be reaching 447GW in the next five years and by year 2014 end, Asia will lead the world in installed wind capacity.

  • It's an expert estimation that the total energy stored in wind is 100 times higher than actually needed by humans on this earth. The catch is that we have to learn and devise ways to trap this wind power blowing across the planet earth. Experts tell us one more thing that most of the wind energy is available at high altitude and we can’t manufacture turbines of that height. So we have to think of new ways to trap that wind power blowing at a significant height. Some experts estimate that the total energy contained in wind is 100 times the amount needed by everyone on the planet. However, most of this energy is at high altitudes, far beyond the reach of any wind turbine.
