Alternative energy

Alternative energy refers to power produced from non-conventional energy sources. They could be renewable energy sources, nuclear energy and power generated from biofuels. These days, a lot of importance is being attached to alternative energy for the simple reason that conventional energy resources are depleting and are fast becoming costlier. Besides, the tremendous boom in population and demand for electricity from households and industries is forcing power utilities to explore newer and cheaper options to produce power. The focus is also on alternative energy resources since they are sustainable on a long term basis and considered environmental friendly.

Many power utilities in developed countries are exploring with various alternative energy resources to add strength to the national grid. The latest innovation in the alternative energy sector is tidal energy. Power is produced from tides on the sea cost by building mini dams stretching for long distances. This alternative energy form has become popular in the Scandinavian countries, which are producing tidal energy. Basically, a tidal power plant is run by a government agency since it requires various approvals and investments. The tidal energy plants are based on twin technologies. The first technology employs flow of water to run the turbines. Water is drawn into a dam during high tide and released with great force during low tide. The flowing water causes the turbines to generate power. The second technology has blades inserted in the water to turn whenever the water flows through them The turning blades are connected to the turbine, which produces power.
