RENEWABLE SOURCE OF ENERGY

ABSTRACT

This paper deals with the renewable source of energy. To meet the daily needs we are depending upon fossil fuels. Fossil fuel resources are used up rapidly without any chance for their bringing back to initial state. In a sharp contrast, burning of fossil fuels in cars and factories has a great affect on atmosphere. Air pollution results to so call greenhouse effect. Gases like carbon dioxide are emitted from burning this sort of fuels. The global temperature is  rising sharply due to increasing concentrations of greenhouse gases in the atmosphere. This rise in temperature is creating change in the world's climate which will have enormous consequences for people and the planet. The new results underline the urgency of bringing global CO2 emissions under control. Earth is losing its restorative capacity to absorb CO2 emissions in the face of the massive increases in emissions over the last half century. The longer we delay reducing emissions, the most restorative capacity will be lost.

The best alternative for these problems is using renewable source of energy. The need for using renewable source of energy is to alleviate the problems of global warming and climate change. In this paper some of the renewable sources like biomass, solar, geothermal, wind, water energy  are discussed  and the reason for not using the renewable source of energy for all purposes. The main aim of this paper is to get transition from petroleum-based energy systems to one based on renewable resources to decrease reliance on depleting reserves of fossil fuels and to mitigate climate change. This paper throws light on modern renewable energy techniques like getting energy from algae biofuels, energy from hydrogen producing bacteria, artificial trees to harness solar and wind energy, energy from solar road ways, solar energy from butterfly wings, running a car on wind energy, clean energy from flowing waters etc.

INTRODUCTION: 

In the past century, it has been seen that the consumption of non-renewable sources of energy has caused more environmental damage than any other human activity. Electricity generated from fossil fuels such as coal and crude oil has led to high concentrations of harmful gases in the atmosphere. This has in turn led to many problems being faced today such as ozone depletion and global warming. Vehicular pollution has also been a major problem. Therefore, alternative sources of energy have become very important and relevant to today’s world. These sources, such as the sun and wind, can never be exhausted and therefore are called renewable. They cause less emissions and are available locally. Their use can, to a large extent, reduce chemical, radioactive, and thermal pollution. They stand out as a viable source of clean and limitless energy. These are also known as non-conventional sources of energy. Most of the renewable sources of energy are fairly non-polluting and considered clean though biomass, a renewable source, is a major polluter indoors.Under the category of renewable energy or non-conventional energy are such sources as the sun, biofuels, hydroelectric energy, tidal, wind energy etc.

CONCLUSION:

Renewable energy is proven technology, the price is dropping, the rest of the world is going that way, that's where our investment should be going as well. We need to push ourselves to make as many reductions as possible in our own energy use first.. and that takes time. But we must do this quickly as the climate will not wait for us. So there is an urgent need for transition from petroleum-based energy systems to one based on renewable resources to decrease reliance on depleting reserves of fossil fuels and to mitigate climate change. In addition, renewable energy has the potential to create many employment opportunities at all levels, especially in rural areas. An emphasis on presenting the real picture of massive renewable energy potential, it would be possible to attract foreign investments to herald a Green Energy Revolution in India.
