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.

Finding Our Way Past Non Renewable Energy

Finding Our Way Past Non Renewable Energy
There are all kinds of choices in energy sources in the world today. Thanks to modern technology and development most consumers in developed nations can choose between renewable energy sources and non renewable energy sources to provide the power they need in day to day life.

Renewable energy sources include solar, geo-thermal, wind, hydroelectricity and biomass. These types of energy are termed renewable because they come from infinite sources such as the sun and the wind, running water and the burning or decomposition of various types of waste. These types of energy are endlessly abundant and do not take a toll on the earth.

Non renewable energy sources include coal, oil, natural gas and other products that are available only in finite amounts wrested from the earth. These products are fossil fuels. They took thousands of years to develop far beneath the surface of the earth. Once they are used up, there will be no more.

This very basic comparison should make it easy to see why energy sources that are not renewable are a bad choice. The fact that they will be used up one of these days in the not-too-distant future is a very big negative. Add to that the fact that sourcing these materials is horribly damaging to the only habitable planet in the known universe and it is easy to see that continuing to choose non-renewable sources of energy is a very foolish choice, indeed.

Coal mining is a horribly destructive practice. This is especially true of mountaintop removal coal mining in which entire mountaintops are simply blown to smithereens to get to the coal that lies inside the mountain. When this is done, the mountain is destroyed along with all life on the mountain. Streams that may run from the mountain are polluted and destroyed. Entire towns lose their source of water. Illness from the fallout of the destruction often ensues.

Traditional coal mining in which miners go underground to mine coal is also horribly destructive and very dangerous. Miners are always in danger of cave-ins and they inevitably develop lung cancer and other occupational illnesses, the longer they work in the mines. Mining is a debilitating job and many miners spend the vast majority of their hours underground slaving away in the mines.

Drilling for oil and gas is also horribly destructive. Wast areas of land are despoiled and the air surrounding wells is polluted by the heavy machinery used to make the wells. Heavy equipment also destroys roads all around the wells, and most often the gas and oil companies are not held accountable for the destruction.

Fracking is a practice that is used to break up deep deposits of shale to get at formerly inaccessible sources of gas and oil. This practice wastes millions of gallons of water and pollutes aquifers. It is rapidly destroying sources of water in all areas where fracking is performed.

Oil spills from tankers and pipelines poison the earth and every living thing upon and beneath it. The destruction they wreak in the ocean is well-known.

Energy from the sun, wind, water and constantly renewable materials that must be disposed of does not destroy the earth. These forms of renewable energy do not pollute water. Jobs in renewable energy are interesting and healthy and growing in number by the day.

When comparing non renewable and renewable sources of energy, it should be quite clear that only infinite and renewable choices have the ability to carry us safely into the future.
