Renewable energy is the type of energy that comes from natural resource like the sunlight, wind, rain, biomass and a tide not forgetting the geothermal heat. When it comes to the renewable energy share on electricity generation is basically estimated to contribute 19% having a part of 16% of global electricity which is gotten from the hydroelectricity and another small amount from new renewable energy like solar energy.
Wind energy is mostly used in Europe, Asia, and the United states and it’s growing very fast and very high speed that’s estimated to be 30% each year. Many people are going for the wind energy because is one of the easiest to install and manage as well. The solar thermal power is usually done and operated mostly in USA although it’s grown a lot everywhere at a very fast speed everywhere in the world. For the geothermal power the largest is the geysers found in California which has a rate capacity of 750MW.with the ethanol fuel Brazil is said to lead followed by the USA. Ethanol is said to provide 18% of automotive fuel to the Brazilians. This kind of fuel is sparsely found in the USA as well. The ethanol fuel is usually got from the sugarcane and it does well in places where the climate favors the growth of the sugar cane.
The best place to start any project of the renewable energy is at the rural areas where energy is in high demand when it comes to human development. The best part that is played by the renewable energy is that it replaces conventional fuel in the following areas; electricity provision, water heating, motor fuels and the rural energy services. Below is the analysis on the way each one works. Power generation is said to give 19% of electricity generation in the whole world. Many of the countries get most of their power form all types of the renewable energy. Some of the countries that get most of the power from the renewable include Iceland and Paraguay with 100% ,Norway with 98%, brazil 86%, Austria 62%, New Zealand 65% and Sweden that has a percentage of 54. Heating is another most used way to utilize the renewable energy. Almost everyone will need to use hot water in their homes for different kind of work like taking shower, cooking, washing ad many more that will always be of importance to them at the end of the day.
Solar heating is mostly installed in china at multifamily apartment buildings and all have people in them to be using the hot water. In some countries like Sweden the use of biomass for heating is outweighing the oil. Transport fuel is among the main fuels that will need to be used on daily basis and so making it produced in large quantity everywhere in the world. Wind power is among the main stream forms of renewable energy and is mostly used in Iran country with the latest technology on how to install and how to it as well. For commercial use, turbines with a rated output of 1.5-3 MW are mostly used. It is definite that the power output of a turbine will be determined by the wind speed so when the wind speed increases the power output also increases. There are the most preferred places for wind farms like the off shores and the high altitude sites due to the strong winds that they experience. Wind energy is on high demand and when the installation is done in large it remains to serve very many people and do so many things at the same time. In some Arab countries this is the main source of energy and it has brought high impact on the economy and the social factors of the countries.
Hydropower is the power that is gotten through water that under goes a process to become power. In the US state of Washington, there is the Grand Coulee Dam that is a hydroelectric gravity dam found in the Columbian river. There are two well known large scale hydroelectric dams in the world which are namely the Grand Coulee Dam found in the Washington state and also the Akosombo dam found in Ghana. There are also various ways of getting the water energy and they are outlined below
Hydroelectric energy; is basically for large scale power generation
Micro hydro; this usually produces up to 100KW of power. They are most of the time used in the remote area power supply (RAPS)
Run of the river hydroelectricity; here the water is direct from rivers or oceans without the involvement of the dam.
Solar energy; solar energy is gotten from the sun just as the name suggests and it’s through the solar radiation. There are several solar applications like the solar architecture, day lighting, solar hot water, solar cooking not forgetting the high temperature gets required heat for commercial purposes. It is categorized into two, the passive solar and the activity solar that will depend on the much they capture, convert and also distributing of the solar energy.
Biomass; is basically the plant material and the energy contained in it will come from the sun. The plants will receive the sun through photosynthesis and hence release the suns energy when heat which is a renewable source of energy. These are like natural batteries for storing the solar energy, for the elasticity of the battery you need to grow as much plants as they are being used as well. There are two main ways used in plant for the energy production which are the first and third generation biomass (growing plants purposely for that) and the second generation biomass which is gotten by the use of the residues.
Biofuels; this is known to produce2.7% of the worlds transport fuel statistics that were taken in the year 2010.these biofuel will refer to the solid biomass, liquid fuels and some biogases .for the liquid bioalcohols like the bioethanol and oils like the biodiesel. For the gaseous biofuel we find the biogas, land fill gas and synthetic gas.
Geothermal energy; this is the last in the discussion and it is found or generated ad stored in the earth. This occurs due to the radioactive decay of minerals which is an estimate of 80% and the original formation of the planet which is also estimated to take 20%.
Basically the renewable energy has brought a great effect in the world as this is the only energy that everyone is going for and finding it easy to utilize and also coup with the services that it is producing. To many it is becoming a good source of investment and it is reality helping greatly like the solar energy that everyone is turning to , to do all home duties that the renewable energy.
