An increasing Global warming, currently occurring on this 4.6 billion years old earth, is a very critical issue to be addressed by the modern society that has been enjoying economical growth by consumption of fossil energies Since the Industrial Revolution in Great Britain, much carbon dioxide (CO2) has been emitted as a result of the combustion of petroleum and coal. In the past 200 years, the carbon dioxide concentration in the atmosphere has increased by as much as 25%. Now the entire earth is, so to speak, situ three of the most prominent issues facing the world today are escalating climate change, energy security and meeting the increasing global demand for electrical energy generated from renewable sources. The renewable energy is growing technology for meeting the demands of energy consumption to solve the problems of fossil fuels and at the same time reduce the pollution in the atmosphere. In case of fossil fuels once it is used that can’t regenerated means it is converted into electricity and is used by consumers. Where as in case of renewable sources the energy generated is unlimited. Hence the importance of renewable energy is becoming a great technology and today the world seeing to develop these technologies.
Renewable sources are also called Echo friendly technologies are very important due to their pollution free energy generation and having sustainable growth. There are many sources of energy that are renewable and considered to be environmentally friendly and harmless natural processes. These sources of energy provide an alternate “cleaner” source of energy, helping to negate the effects of certain forms of pollution. All of these power generation techniques can be described as renewable since they are not depleting any resource to create the energy. While there are many large-scale renewable energy projects and production, renewable technologies are also suited to small off-grid applications, sometimes in rural and remote areas, where energy is often crucial in human development.
