Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

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.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

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.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Amazing Solar Energy Facts

Amazing Solar Energy Facts
Article by Barry Brenner

Solar energy has created quite a buzz since in the last decade. More and more homeowners and scientists are talking about whether or not to implement solar power in our factories and homes. The truth is that unlike other forms of energy such as oil or gas, solar energy is a renewable type of energy that is free and completely eco-friendly. If you want to learn more about this new source of energy, read the following mesmerizing solar energy facts.

- It is much better for the environment than any other source of energy. There is no pollution created from solar power systems.

- It has a wide variety of uses. You can use it to heat water, cook, heat swimming pools, power cars, attic fans and other appliances.

- The supply of energy from the sun will exceed the global demand for energy and replace the need for fossil fuels.

- An average household in US uses approximately 867 kilowatt per hour.

- A home photovoltaic panel system is comprised of an inverter, several panels, a charge controller, and a battery, support and wiring structure. And the

- A 1-kilowatt standard solar system features about 10 solar panels. The installation area should be of over 100 square feet. One of the benefits is no maintenance necessary except for keeping your solar panels clean. These solar systems costs around 10,000 and takes two days to install.

- A standard solar system's initial cost pay off is about 20 years, depending on your monthly savings. This is among the most important solar energy facts. It also increases the value of your home.

- A solar system comes with at least 5-years warranty, while solar panels have at least 20 years.

- Solar panels come in several unique colors that cater to any taste.

- Sun powered energy can be either stored into batteries or insulated, reflected, transmitted or absorbed.

- Da Vinci predicted the use of solar energy back in the 15th century.

- In 1990 a solar powered aircraft established a new world record, flying 4060 kilometers all across USA without any fuel, except solar power.

- According to Shell Oil, by 2040, over 50% of the world's total energy will come from renewable sources, such as biomass, wind, solar and geothermal.

All these amazing facts can make us understand the real importance of solar energy for us today, so don't hesitate to discover more about this unique source of power.
