Tidal power, often referred to as tidal energy, is a type of hydropower that harnesses the energy of our ocean’s tides or other flowing waterways to produce power, usually in the form of electricity.  As sea levels rise and fall or the currents flow underwater a potential energy is created.  By using equipment such as tidal energy generators and underwater turbines in areas of high tidal movements, the kinetic motion of the ocean can be used to turn the turbines, thus producing electricity. 

Burning fossil fuels creates carbon dioxide, the number one greenhouse gas contributing to global warming. Combustion of these fossil fuels is considered to be the largest contributing factor to the release of greenhouse gases into the atmosphere. In the 20th century, the average temperature of Earth rose 1 degree Fahrenheit (1°F). This was a period that saw the most prolific population growth and industrial development

Some estimates say our fossil fuel reserves will be depleted within 50 years, while others say it will be 100-120 years.
