1. Renewable Energy By Claire and Nicola

2. Solar Power Solar cell technology dates to 1839 when French physicist Antoine-Cesar Becquerel observed that shining light on an electrode submerged in a conductive liquid would create an electric current. In 1941, the American Russell Ohl invented a silicon solar cell.

3. Wind Power As the oil age emerged in the 20th century, wind power appeared to become a footnote in the history of energy technology but, in the 1970s, Danish companies invented a machine with three propeller blades that pointed upwind on a steel tower. The latest versions have variable pitch blades that reflect wind speed. The blades, which can be as long as 40 meters, spin in winds as low as 15 kilometres (9 miles) per hour. They maintain a relatively slow and constant speed, though new electronic variable- speed drives allow blade speed to vary, increasing efficiency

4. Wave Power Wave power or wave energy is the energy that could be generated using the power of the waves that are found at the surface of the ocean. The energy that the waves have or produce is converted into other forms of energy such as electricity. Although wave energy is considered as a renewable source of energy, it has not gained much popularity due to numerous limitations - specifically, how wave energy can be efficiently used for electricity generation

5. Why Renewable Energy is Better Renewable energy is better because it helps the environment. Renewable energy is better because it saves electricity. Renewable energy is better because the sun, the wind and the waves don’t run out. Renewable energy is better because IT JUST IS!!!
