How Do Alternative Energy Sources Work

The traditional forms of energy that are so extensively used by us involve burning them to produce the energy that we require. Alternative forms of energy are fast gaining popularity and substantial attention all around the world for various reasons. The alternative forms of energy that we are talking about are renewable, cost effective, fairly easy to use and very friendly to the atmosphere that surrounds us. This is not just one form of energy, but there are several other forms of energy that we can term as Alternative energy sources.

All forms of energy, regardless of whether they are renewable or non-renewable, have their own advantages and disadvantages. Science has sufficiently led us to the conclusion that the alternative forms of energy such as hydroelectricity, solar power and nuclear energy have greater advantages than the traditional forms, and can thus be used for satisfying our everyday energy requirements. In addition to all this, oil prices have soared sky high, and the harmful effects of using oil as a source of energy has brought it under scanner.

Abundant water is an excellent source of energy – 90% of the energy produced from renewable sources are produced from water, in the form of hydroelectricity. 20% of the electrical energy produced all around the globe comes from water bodies designed for the production of hydroelectricity. Dams that are constructed to store water are used to generate electricity. Water is stored at such a height so that it develops a potential energy in it, which if made to fall directly on turbines generates large amounts of electricity. This mode of producing energy is the most ancient and also the most popular method of producing energy from renewable sources. Furthermore, the energy produced using this method is also very cost effective.

The alternative sources of energy are more than just one, and form a completely different category. Also, the forms from which the energy is generated vary significantly from one another. Therefore, there is no general pattern that can explain the working of these sources of energy by a rule or law. Each of these sources works on its own set of principles and have their own way of functioning. Highlighted below are some popular sources of energy that are classified as renewable energy sources.

Solar energy – a very popular form of energy that can be stored and harnessed with the use of solar panels, photovoltaic cells and solar calculators. Solar energy can be used to warm your home and also to power up most of your electronic appliances. The solar technologies that are used to store solar energy are broadly classified in two parts – active solar and passive solar. The method used to capture the energy, convert it and then distribute it are the main factors that define the class of these technologies.

Nuclear energy – this can either be nuclear fusion or nuclear fission. Nuclear fusion involves the merging of the atoms to generate energy, whereas nuclear fission refers to the process of splitting the atoms. The installation and use of devices that can do either of these is very complex, and thus cannot be used for small scale generation of energy. Nevertheless, this is also an alternative source of energy, and is expected to reduce the dependability of consumers on the traditional sources.

Alternative energy sources is not a new term. Due to the disadvantages and the sky-high rising prices of the traditional sources of energy, it has now become important that we start thinking about these alternative energy sources quite seriously and also educate the younger generation on solar energy facts for kids.
