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. Here is a list of Top 10 renewable energy sources.
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.
