World is striving for pollution free environment and environment friendly energy resources. There are a number of energy resources which are environment friendly or they don't have harmful effects on environment. Now the answer to the question on their needs? World is very much upset due to Ozone depletion, green house effects and other pollutants like Coal, petrol, smoke etc. In order to avoid all these pollutants and harmful effects on environment there is a need of these energy resources. They include Solar, Wind, Hydal, Energy from Piezzo crystals etc.
Fossil resources are not infinite, they pollute, and they harm the planet in many ways. green energy is a hope to mitigate these problems.
Renewable energy is important because of the benefits it provides. The key benefits are:
Environmental Benefit.
Energy for our children's children's children.
Jobs and the economy
Energy Security
Green energy is important because all of the oil gas will be finished in future so need to be reduce the dependency on the oil and gas to protect our earth from the crisis of oil and gas.
The industrial revolution that began in the second half of the18th century changed the world, with new methods of machine-based manufacturing leading to a profound increase in economic growth, population growth, and quality of life. At the time, the long-term consequences could not even be conceived of, much less felt; however, the burning of vast quantities of fossil fuels, such as coal and oil, has caused a great deal of harm to the environment. Most climatologists agree that the use of fossil fuels has contributed significantly to global warming. This term refers to the measured increase in the Earth’s surface temperature since the late19th century and the environmental effects of this change.
The primary goal of developing green sources of energy is to generate power while minimizing both waste and pollution, to thereby reduce the impact of energy production on the environment. Scientists who advocate the use of green energy say that using such sources will reduce the rate at which climate change occurs, although it cannot stop or reverse the temperature increase. Another important objective is creating energy sources that are renewable. This is in contrast to fossil fuel sources, which are finite and estimated to be depleted before the end of the22nd century.
