Ocean Thermal Energy Conversion SPH3U I. Introductory Covering over 70% of the earth ’s surface‚ water is one of the most amazing energy sources. From olden times‚ people had previously utilized the force of the waters in order to crush grain or help them to do their work more efficiently. Since then as a power source‚ water draws a lot of attention due to the efficient manner in which it gets to produce electricity. Ocean Thermal Energy Conversion (OTEC) is a method introduced in

The Arctic and areas that are in higher latitudes have a higher rate of warming and this pattern is expected to continue as climates everywhere changes and temperatures go up. As Earth warms up‚ the glaciers in the Arctic start to melt‚ and species such as the polar bear and the arctic fox that depend on the sea ice‚ will start to disappear

As their normal habitat gets hotter it goes down in size‚ this consequence leads to fewer polar bears. For the polar bear‚ which is a non replaceable symbol of the Arctic‚ climate change could cause extinction of polar bears. Temperatures in the Arctic are increasing at almost twice the rate as the rest of the world. Since 1973 the Arctic sea area ice has
