Energy is integral part in everyone’s life today, as all equipment that we use on regular basis work with help of power or electricity. But with passage of time sources to produce energy are getting expensive and becoming rare, therefore as an alternate solution to this problem renewable energy has been thought of. This is an energy that is generated by using natural resources, which are available in almost all part of the world. Common natural resources used of this purpose includes wind, tides, sunlight, heat, rain etc. All these are used today to produce electricity on large scales, and according to some survey‘s it is founded that almost 16% of total worlds energy comes from these sources of energy.
Other research data give us accurate detail about how much of energy needs is meet by these sources, a quick overview tells us that 10% coming from traditional biomass, 3.4% from hydroelectricity. If count total share that renewable energy has today in this world then it would be more than 19%. From which 3% is accumulated through renewable while remaining 16% comes from hydroelectricity.
Types of renewable energies:
To produce renewable energies natural processes are used that replenished over and over. There are many sufficient sources to generate great amount of energy to fulfil world’s requirements. Some major types are discussed here.
Wind Energy:
Wind power is very affordable and efficient mean to generate renewable energy as it is pollution free and cost competitive method. In recent years this type of energy generation is growing widely as in 2010 only. 2900 wind turbines are installed in US only. Use of wind power has added 20% to total energy produces annually, as it is giving more than 238,000 MW each year. This type is widely used to generate electricity in Asia, Europe and US.
Geothermal Energy:
This type of renewable energy comes from reservoirs of steam and hot water that is founded in beneath of earth’s surface. There are many place in the world which are good for this reason, it is counted among least explored source of energy till now around the world. In 2010, 3000 MW were produced with help of this type in US only. Today more than t 200 projects are working under this type, in order to generate more amount of energy easily.
It form of energy is collected when magma come close to surface of earth and its heat raise temperature of underground water and cracks the rocks. Deep wells are famously used to save this high energy level.
Biogas Energy:
In this type energy is generated animal manure, this is very cheap and easy way to generate energy and it give ease to farmers to produce their own electricity with their personal resources for their own farms. This energy is produced when bacteria decompose manure anaerobically into gas mixture. This mixture generates heat and electricity and throws the waste away to use it for other purposes.
Solar Energy:
If we look back then we will find that in last few decades, due to technological advancements solar plants are becoming factor of interest for all. Reason of popularity of solar panels is its affordability and easy to made and handles features. At first these solar panels were designed especially for offices, satellites, vehicles, warehouses and building etc. but today they are providing electricity in more cheaper rates than any other type of renewable or non renewable energy.
To generate power through solar panels, sun’s energy is used. It’s heat is captured directly through mirrors and then cells convert it into electricity. It is famously used today in almost all parts of the world. There is whole website dedicated to renewable energy sources here is the link – www.solarpowernotes.com
