Significance Of Renewable Energy Resources
We are living in a world which is fueled by all types of exhaustible energy sources. Fossil fuels form the major source of our day-to-day energy consumption. From liquid petroleum gas in the electricity we use to light up our homes, almost 80 percent of the fuel we use are created from natural resources that are nonrenewable even in a million years’ time. The sad part is people hardly realize the seriousness of what they are told by environmentalists and government authorities. It is estimated that if people avoid leaving their lights, televisions, air conditioners, computers, fans and radios on for hours, they can save around 40% of energy wastage. In several Asian and Middle East countries people are ignorant about the relevance of energy conservation. This has forced scientists to come up with renewable energy resources for generating fuel and electricity.
What Are Renewable Energy Sources?
As explained above, all of our energy needs are fulfilled by harnessing natural resources. These resources are classified into two major categories – Renewable and Nonrenewable. Renewable resources are those that can be remade with the help of natural or artificial procedures. Biomass, water, geothermal, solar and wind are some of the best examples of renewable energy resources. Nowadays, yet another inexhaustible source known as ocean thermal power is used to produce electricity. Around 10% of electricity is generated with the help of renewable energy. Hydroelectricity generation which makes use of water as a main power that drives the turbines is considered as the safest form of energy conversion. The emissions from hydroelectricity plant contribute around 4% of the entire greenhouse gas production. For this reason hydroelectricity is considered as the lowest-polluting power production system in the world.
What Is Non-Renewable Energy?
Since the rise of industrialization, scientists have started devising several ways to exploit fossilized fuels. In the 18th century coal was the major form of natural energy resource. During those days electricity consumption was limited but coal was heavily used for running steam engines for trains. Over time, petroleum as well as natural gas was discovered. This was a phenomenal discovery which changed the face of human existence. Even today, these resources form the major source of electricity generation and fuel for cooking and running vehicles. As of today, 24 percent electricity production in the US is powered by natural gas. Petroleum is mainly used for producing petrol and diesel and only 1% of power generation occurs with the help of petroleum.
The Concept Of Green Energy
The word green has been used as a universal symbol for denoting anything which is eco-friendly. Since greenery or greenness represents plant life, it is a color used for promoting various concepts and ideas by environmentalists and naturalist’s world over. Green Energy stands for renewable energy that produces minimal or zero pollution. Environmental pollution is a major issue faced by our power and fuel generation departments. Green energy resources like water and wind are considered to be a safe and eco-friendly medium. These sources generate minimal greenhouse gases during their process of conversion into electricity or fuel. Solar energy is also a major form of green energy which is a powerful inexhaustible source.
