Top 10 Energy Sources that are Renewable
Energy is an inevitable requirement where we want development to take place. Many naturally occurring phenomenons contribute to producing this energy without damaging the environment. They are called renewable energy sources and they help to avoid pollution; both in urban and inaccessible locations on large and small scales. They form a sort of cycle without the deduction of any resource to generate the energy.
10. Tidal Power
The tidal power is not a very popular energy source, but has immense potential of becoming one in the near future. Tidal stream generators and barrage generation make use of tidal power. It is Eco-friendly and does not harm the environment at all. It follows the same principle as wind turbines, but instead of air, the generators rotate in water. Unlike wind and solar energy, tides can be predicted. Since time immemorial, tide mills have been driven directly from the relative motions of the Earth–Moon system and to a lesser extent from the Earth–Sun system. Lunar Energy, a British company was the first to establish a tidal farm in the coast of Pembrokshire in Wales, providing electricity to thousands of houses.
9. Wave Power
Predicting the direction of ocean and wave is a very difficult job, but is not impossible. Wave power is the transport of energy by ocean surface waves, and the capture of that energy for pumping or desalinating water and generating electricity. In Europe, wave farms have been introduced, using floating Pelamis Wave Energy converters. They use a floating buoyed device and generate energy through a snaking motion, or by mechanical movement from the wave’s peaks and troughs. Wave power is not the same as the diurnal flux of tidal power and the steady gyre of ocean currents, although it is confused to be so often. We have been pursuing this technology since 1890 and the world’s first commercial wave farm is based in Portugal, at the Aguçadora Wave Park, which consists of three 750 kilowatt Pelamis devices.
8. Solar Power
Producing electricity by making use of the sun’s energy and the photovoltaic (PV) cells is called the Solar Technology. Solar cells are becoming more efficient, transportable and even flexible, allowing for easy installation. Let it be a calculator powered by a single solar cell or off-grid homes powered by photovoltaic disarray; PV can power applications of all sizes. The 1973 oil crisis stimulated a rapid rise in the production of PV during the 1970s and early 1980s. Steadily falling oil prices during the early 1980s, however, led to a reduction in funding for photovoltaic R&D and a discontinuation of the tax credits associated with the Energy Tax Act of 1978. These factors moderated growth to approximately 15% per year from 1984 through 1996. Since the mid-1990s, leadership in the PV sector has shifted from the US to Japan and Germany.
