Renewable & Sustainable Energy (Solar Energy, Wind, Biomass, Hydrogen, Geothermal, Ocean & Hydropower)

Solar & Wind EBooks

Renewable energy is a green technology, friendly with no harm to the environment. Any effort or contribution for spreading the use of this safe technology will result in getting pure sustainable energy & saving our mother earth at the same time.

Renewableenergy resources are naturally replenished in a relatively short period of time. They include biomass, hydropower, geothermal energy, wind energy, and solar energy. In 2005, about 6% of all energy consumed, and about 9% of total electricity production was from renewable energy sources. Alternative transportation fuels are fuels used for transportation other than gasoline or diesel. Some alternative transportation fuels, such as ethanol and biodiesel, are renewable while others, such as propane and natural gas, are non-renewable.

The United States currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are nonrenewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources—such as wind and solar energy—are constantly replenished and will never run out.

Solar

Most renewable energy comes either directly or indirectly from the sun. Sunlight, Solar energy technologies convert the sun’s light into usable electricity or heat. Solar energy systems can be divided into two major categories: photovoltaic and thermal. Photovoltaic cells produce electricity directly, while solar thermal systems produce heat for buildings, industrial processes or domestic hot water. Thermal systems can also generate electricity by operating heat engines or by producing steam to spin electric turbines. Solar energy systems have no fuel costs, so most of their cost comes from the original investment in the equipment. These are now also being used by many home and farm owners who simply build or buy their own very small solar panels and wind turbines which provide a constant supply of energy in their home or buildings. To try to make  solar panels and use renewable energy yourself with lowest cost  we recommend homemade energy.

Wind

The terms “wind energy” or “wind power” describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like. The sun’s heat drives the winds, whose energy is captured with turbines. These are now also being used by many home and farm owners who simply build or buy their own very small windmills and turbines which provide a constant supply of energy in their home or buildings as well.

Biomass

Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called biomass energy.

Hydrogen

Hydrogen also can be found in many organic compounds, as well as water. It’s the most abundant element on the Earth. But it doesn’t occur naturally as a gas. It’s always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.

Geothermal

Not all renewable energy resources come from the sun. Geothermal energy taps the Earth’s internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean’s tides comes from the gravitational pull of the moon and the sun upon the Earth.

Ocean

The ocean can produce thermal energy from the sun’s heat and mechanical energy from the tides and waves.

Hydropower

Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. For more information on renewable energy use and benefits please read the other articles by the same author on  Articlesbase, Ezinearticles or Goarticles etc..
