Evolution of Different Types of Alternative Energy and Their Uses in Our Society

Sources of energy which are exploitable or usable upon research are considered to be alternative forms of energy. There are a variety of sources of alternative methods of energy which can replace ordinary sources. When these alternative sources of energy can be used for each is home is depends on changes over time.

The most basic source of energy is wood. Long ago, wood was originally used to heat wood stoves and cooking. In today’s times, wood is becoming harder to find and people are looking for new ways to replace the use of wood. Coal is often substituted as an alternative source of energy. Coal is very abundant. By merely creating a coal mine, coal will be present.

Another alternative energy source is petroleum. Whale oil was once used during the 19th century but has since been replaced with petroleum. The whale oils were typically used for lamp fuel and lubricants. Petroleum is not used because it is much cheaper to produce.

As previously stated, petroleum is the very best alternative method rather than using whale oil. Petroleum is becoming more limited these days and other alternatives are being sought after. Coal gasification has been used many times in replacement of petroleum. By using coal gasification, gas is produced from coal.

Alcohol is considered to be an excellent alternative energy source. A long time ago, people used to use fossil fuels instead of alcohol. Fossil fuels became very scarce as well as expensive. In 1917, the use of alcohol was implemented an alternative to energy. The benefit of using alcohol is the fact that by building an ethanol plant makes the process very successful.

Zero carbon alternatives are another source. In many countries where the climate changes often and storing energy is difficult, the use of biomass combustion and hydrogen is being used. This is derived from the use of natural gas and is not present in any alternatives which are available because the world wide use is not common at all.

There are a few countries who treat the use of natural gases as an effective and alternative energy source. When compared to using petroleum, natural gas is effective to use an alternative. Some of the potential sources of energy of natural gases include the decomposing of landfill waste, waste materials of the agricultural industry, and any plant or manure parts which are unused. There are also many more..

In our evolving age of advancement and technology growth, there are many countries who are now resorting to using geothermal and hydro plants in the production of energy. This type of energy is considered to be renewable. There are many other examples such as solar energy resources. Solar energy is energy which is produced from wind mills and the ocean. The use of solar energy is considered to be the very best alternative rather than the use of fossil fuels, coal or petroleum. These energy sources are renewable because energy is produced without combusting or wasting anything. The source of renewable energy is being used as an alternative in today’s times because this source remains unlimited and very accessible.

Today, alternative sources of energy are getting popularity all over the world. There are various reasons for their popularity. Alternative energy is cost-effective, renewable, eco friendly and easy to use. These days several kinds of alternative power are available. Each kind has its own advantages as well disadvantages. The most famous and developed types of alternative energy are solar energy, nuclear energy and hydro electricity. By using these alternative sources of energy, you can get rid of consistently increasing oil prices and consumption of fossil will decrease.

About 90% of the global energy comprises hydroelectricity. Also, this alternative source of energy accounts for 20% of the world’s electricity. To produce hydroelectricity, water stored in dams and release from an enormous height. Force of water help turbines to move which in turn generates electricity. Hydroelectricity is one of the most popular, widely used and ancient form of alternative energy. It is also known for effectively meeting the electricity requirements especially in highly populated areas that too at cheaper rates.

Alternative sources of energy include various different modes and each mode differs from the other in many ways. Every form of alternative energy works on its own set of sources of energy. We can tap the ubiquitous form of alternative energy using solar panels, photovoltaic cells and solar calculators. Solar energy is used to keep homes warm and generating electricity.

Solar technology can be categorized into two major parts i.e., active solar and passive solar techniques. Both these techniques differ in capturing of sunlight, its conversion and distribution. Active solar technique incorporates photovoltaic panels and few magnetic gadgets to capture sun’s rays so that they can be transformed into more productive forms of energy. In passive solar technique sunlight converted into usable heat without using any active mechanical system. Solarium on the equator side of any building is common example of passive solar technology. Few passive systems use conventional energy to control shutters, night insulation, dampers and other devices to enhance the collection the collection of solar energy.

Wind energy is one of the alternative sources of energy. In this technique, forces of moving winds allow turbines to move which in turn generates electricity. Windmills are built to produce wind energy. Places characterized by gusty winds are best location for windmills. The technology of wind energy is simple; therefore, can be replicated at any place with gusty winds. Nuclear energy is not so old mode of alternative energy. There are two ways of producing nuclear energy. First is nuclear fusion in which the reaction deals with merging of atoms. With nuclear fusion reaction, safety concerns such as disposal of radioactive waste products have been associated. Nuclear fusion reaction includes splitting on an atom.

Besides these alternative sources of energy, there are many sources also available. Some of them are bio diesel, tidal energy and ethanol. These alternative sources of energy can be used without any hesitation as they are available in abundance just like traditional forms of energy.
