Abstract: In an energy-hungry world people is seeking for energy to meet up for the future crisis. But oil, gas, coal and other recourses will be finished within 40 years. So, renewable energy is the only solution in order to meet up the future crisis. Solar, wind, wave, tidal, fuel cell, geothermal etc are the renewable energy sources. Among them tidal energy is an old but efficient method. If there is one thing we can safely predict and be sure of on this planet, it is the coming and going of the tide. This gives this form of renewable energy a distinct advantage over other sources that are not as predictable and reliable, such as wind or solar. Rise and fall of tides is more cyclic than random weather patterns. Using this free source we can produce a large amount of power which is very reliable and continuous. The main objective of this paper is show that tidal power may be an alternative solution to meet up recent power crisis.
