Introduction
“‘Climate change’ refers to any long-term change in Earth's climate, or in the climate of a region or city. This includes warming, cooling and changes besides temperature.” (NASA Oct.2011) Earth is going through the climate change of global warming. Climate change is causing a big threat that would cause great catastrophe to the world and this problem will influence everyone around the world. These changes are caused by the greenhouse gases which are produced when burning fossil fuels and transportation. When fossil fuels are burned, they generate a fair amount of energy for people, but at the same time, produce large amounts of pollution that damages our Earth. To slow down climate change, we need to start making changes and shift our sole energy source from burning fossil fuels to an alternative renewable energy source. While tidal energy is an interesting technology and is capable of providing us a carbon-free society, but it can never generate enough energy to reduce the burning of fossil fuels because of the massive cost for the project and there is limited places in the world to install the technology.

Tidal energy is converted based on the movements of tides. Tidal power is the result of Earth’s rotation combined with the sun and moon’s gravity. The tides come mostly from the Moon’s gravity and a little from the Sun’s gravity. So as the Earth rotates, the ocean surface rises and falls. Compared to nuclear reserves or fossil fuels, the resource of tidal energy will not run out or end unless the sun and moon does. Usually, there are two high tides and two low tides each day. With all the water moving up and down, we can capture the kinetic energy from the tides. It works just like wind turbine except ocean tides turn the blades instead of wind. (Climate Kids,
