Essay --

The populace as a whole has been using resources from the earth for thousands of years. We exercisingd fire for groove and to cook our foods, rocks metals as tools and weapons, and water as a source for make merry and washing. As the population grew in numbers, so did the demand for the earths resources. It wasnt until the industrial age that the United States and receding countries began the sole rehearse of fossil fuels to power homes, buildings, cites and vehicles. This increase in usage intensified the wait and extraction of the demanded resources. The population of the world had exceeded four, five, and even six billion people, which assemble a strain on the earth and its recourses. Pollution increased and the atmosphere, water, cut back were affected drastic each(prenominal)y. The result of the burning of fossil fuels at such a high rates, caused a rapid depletion of the used fossil fuels. This lead to the look for for alternative green nix, including the use of waves (tidal power) to create electricity to meet our demands. Methods of extracting the heartiness from waves are being created, and others have been put to use already. Wave energy is an environmentally safe form of hydropower that harnesses the energy from the up-and-down motion of ocean waves and converts it into electricity using the sole power of the tides. Tidal power uses the change in the high and low tides to the harness energy. These two types of energy provides us with other source we dirty dog use instead of the limited fossil fuels that we use today. Tidal energy is abundant in some parts of the world that have long periods of intense tides. The wave power varies in all parts of the world, areas with abundant wave power include Australia, Scotland, southern Africa, Federal Canada, and the northw... ...n it comes to using the waves, the energy is free because no fuel is requested and no waste by product. It is also relatively inexpensive to operate and concord. The turbines can produce significant amounts of energy which is amazing considering the inexpensive cost to maintain the sites. However, a suitable site is needed for this to function and work to potential. The waves need to be constantly strong to get the maximum output, and the turbines/generators have to metre up to the rough weather out in the ocean. The development of turbines and generators is actually costly and they pose a possible threat to navigation from collisions out-of-pocket to being low profile and above water, making it undetectable by direct sunlight or radar. The sites in which turbines and generators are set up can disrupt marine liveness, including the type and distribution of marine life near the shore.
