Solar radiation is fairly well distributed with average solar radiation of about 19.8MJ/m2/day and average sunshine hours of 6 hours per day. If solar collectors or modules were used to cover 1% of Nigeria’s land area, it is possible to generate 1850 x 103GWh of solar electricity per year; this is over one hundred times the current grid electricity consumption level in the country (Uzoma Et.al,
The above comparisons show that solar energy have impressive magnitude, it provides more energy than present day human technology can provide. The first solar cell were developed about 50 years ago by Bell Laboratories in 1954. These solar cells were used as power source in satellites. In the end of 1970 scientists were able to develop silicon solar cells (Photo voltaic cells) on industrial basis, since then these have become more and more attractive. The main steps involved in utilizing solar energy are Capture, Conversion and Storage.
Renewable Energy Source. Among all the benefits of solar panels, the most significant matter is that solar energy is a genuinely renewable energy source. 9. Reduces Electricity Bills. By introducing net connected solar power system energy bills will drop drastically Generate more electricity than we use, the surplus will be exported back to the grid and the customer will receive bonus payments for that amount Savings can further grow if you sell excess electricity at high rates during the day and then buy electricity from the grid during the evening when the rates are lower.
To produce 1 kilowatt the cost for utilizing solar power is $0.26, for nuclear power it is $0.02 and $0.03 for the equivalent quantity of gas power,” says Mark Robens from the “Disadvantage of Solar Power”, 2014. The average price for a complete photovoltaic system dropped 33% since 2011. Only one two- billionths part of the sun's energy reaches the earth, and the rest of it is lost and only 40% efficiency rate, thus 60% of the
Indian government is promoting solar energy in the form of solar lanterns. Home lighting systems, street lighting systems, solar water pumps and power plants. The total SPV installed ill India is around 160 MW and as a result India ranks fourth in the world in harnessing SPV system after Japan, USA and Germany. 100 KW and 200KW SPV systems have been installed in some parts of country. b) Solar thermal system: solar thermal power plant is harnessed by three methods namely solar concentrated system, distributed system and solar pond.
According to the data in 2013, five top countries that have the largest hydropower capacity, which are China, Brazil, United States, Canada, and Russia, occupied over half of hydropower global capacity (Ren21). China takes 26%, Brazil takes 8.6%, United States takes 7.8%, Canada takes 7.6%, Russia 4.7%, and ‘rest of country’ takes 45.4% of the global hydropower capacity. As annual global capacity reaches 1000GW, China reaches 260GW by itself, while Brazil generates 86GW. Hydropower electricity generated from China is greater than 3times of Brazil’s. To compare hydropower electricity generated in 2012 to 2013, all top 5 counties showed the acceleration (Ren21).
A sustainable energy source is photovoltaic cell. A total of 71.1 GW had been installed by the end of 2011, sufficient to generate 85 TWh /year and the 100 GW installed capacity milestone was achieved by the end of 2012. More than 100 countries today use solar PV. Installations may be ground-mounted (and sometimes integrated with farming and grazing) or built into the roof or walls of a building (either building-integrated photo voltaics or simply
Moreover, the waste generations in eastern and central Asian countries are around 93 million tonnes per year. OECD (the organizations for economic co-operation and development) nations produce 572 million tonnes of solid waste per year. In south Asia, approximately 70 million of household solid waste is generated per year. The solid waste generation is very high in china for the past two decades due to the urban growth, density of population and economic
How do solar systems work Solar power is a very clean, if not the cleanest, reliable source of renewable energy. It is unlimited and can be used in several purposes to power your home or business place. Solar energy is produced during the daytime and is complementary to wind energy (“Wind”). Every day sunlight hit the roof’s solar panels, and the solar panel absorbs the sunlight and converts the photons into electrons of direct current electricity (“How”). This is the start of the process.
It also referred that in the United States, electricity sales and revenue have rise from 40 to 50 billion dollars every year. One study of CNN news reported that in the United States, the 103 nuclear industry has generated electricity for over 20 percent since 1978 (Roderick, 2013). Moreover, nuclear energy is not only a primary global energy source, but also the largest source of free electrical emission (Benefits Nuclear Energy, n.d.). In addition, the meaning of nuclear safety is the accomplishment of avoided nuclear accidents, protected workers, and against dangerous impacts of radioactive material and ionizing radiation (Nuclear energy, n.d.). Other study of CNN, There was a proof that the safest form of alternative energy is nuclear power in the United States over past 50 years (Roderick, 2013).
