Alternative energy is energy that is renewable and is obtained from the Sun, wind, waves, or other natural sources. This is in contrast to energy that is obtained by fossil fuels such as oil, gas, or coal that is not renewable. Alternative energy is a non-traditional method of obtaining energy that has a minimal impact on the Earths environment. Alternative energy is, by its very nature, economically easy on the environment and does not have a harmful effect on the planet.

Due to record high gas prices and increasing concerns about the health of the planet and the long term viability of fossil fuels, alternative energy has been thrust to the forefront of many peoples’ minds. Many companies and individuals are searching for effective ways to use alternative energy and decrease our dependence on foreign oil and fuel. There are many fears that the present supply of fossil fuels will not last, leading to a calamity of catastrophic proportions. Alternative energy is the key to becoming a more self-sufficient and independent as a nation, as well as the only way to ensure the safety of the planet and the long term health of its citizens.

There are many different sources of alternative energy that can be used very effectively. Geothermal energy produces energy from using the heat from beneath the Earths surface and collecting heat from the atmosphere or oceans. Most use a process called flash steam. Solar energy converts sunlight into energy using photovoltaic panels. There are many experts around the country that can install these panels to convert the sunlight into usable energy Another renewable energy source for alternative energy is wind energy Wind is caused by the uneven heating of the Earths surface by the Sun.

Wind energy harnesses this energy by using wind turbines to convert wind power into a usable energy source. Wave power is another method of alternative energy that uses the oceans surface waves to generate electricity and also to desalinate water. Wave power can not be harnessed just anywhere but there are several places around the world that are excellent sources of wave power including Northern Canada, the coasts of western Scotland, southern Africa, Australia, and the northwest coast of the United States.

Alternative energy is widely available and has become very user friendly in recent years. It is a viable way for a person to become more self sufficient while doing their own part to minimize the pressure on the Earth as well as reduce the depletion of fossil fuels and eliminate our reliance upon foreign countries for our energy needs.

Alternative Energy Forms Successfully Developed

The traditional fossil fuels involve their burning for the production of energy. Alternative modes of energy are gaining substantial attention and popularity all across the globe for a variety of reasons. The alternative energy types are usually renewable, easy to use, cost-effective, and friendly to the environment. There are several types of alternative power available these days. Each mode has its peculiar advantages and disadvantages. However, sufficient development has been made in certain types of alternative energy — notably hydroelectricity, nuclear energy and solar power — to warrant the conclusion that the sovereignty of fossil fuels as the mainstay of humanity’s energy needs has little reason to continue indefinitely. This is all the more so because oil prices have maintained ca steady upward climb, and the consumption of fossil fuels is under the scanner for its believed detrimental effects on the environment.

Abundant Water: Excellent Energy Source

Hydroelectricity accounts for about 90 percent of the global energy produced from renewable sources, as well as nearly 20 percent of the overall electricity produced worldwide. Hydel power stems from the force with which water falls. Dams are constructed to store water, which is directed to fall down from an enormous height to move turbines that generate electricity. This mode of alternative energy is among the most ancient, widely used and popular forms available. It has proven effective in meeting the energy requirements of huge populations at cheap rates.

Each With Its Own Paraphernalia

Alternative Energy forms are a motley category and include several different modes that vary markedly from one another. Hence, to discuss how these energy sources work, no general pattern can be outlines. Each energy source mandates its own set of principles and mode of functioning. However, we may well briefly study a few of these sources of power as follows.

Solar energy is a ubiquitous alternative energy form that can be tapped with the means of solar panels, solar calculators and photovoltaic cells. Solar energy finds applications in warming homes and in generating electricity. The solar technologies are categorized into active solar and passive solar, based on the mode adopted for the capture, conversion and distribution of sunlight. Active solar methods use photovoltaic panels and other mechanical gadgets to transform the sun’s rays into more productive forms. Passive solar modes pertain to orienting a building towards the sun or choosing substances with better properties of dispersing light.

Wind energy employs the force of the moving winds to move turbines that lead to the generation of electricity. This alternative energy form is best located in places that are characterized by gusty winds. Windmills are built for the purpose of exploiting the power of the winds. The technology involved is simple and can be replicated anywhere windy with success.

Nuclear energy may be either nuclear fission or nuclear fusion. The former involves splitting of the atom, while the latter deals with the merger of atoms. Nuclear fission has been plagued by safety concerns over the disposal of radioactive waste products that are detrimental to the environment and public health.

Tidal energy draws from the force of the tidal waves. The rise and ebb of the tides occur owing to a complex interplay among the gravitational forces of the sun, moon and earth. The tides are independent of the local weather and lend themselves to easy prediction. The waters are collected and led to mive turbines for the generation of electricity.
