TIDAL ENERGY [pic] *75% of the planet’s surface consits of water. Our water supply transformed a barren planet into a lush green garden of life with a multitude of biodiversity. Water has easily fufilled our every need in many ways. As we near the twentyfirst century‚ a time when public attention is focused on the environment and society is increasing at an ever accelerating rate‚ the energy crisis continues to burden us. Questions of what to do about increasing energy demands and future requirements

In addition‚ renewable energy is generated by natural resources such as sunlight‚ wind and biomass which produce less or no pollution when generate energy. Furthermore‚ renewable energy will be demanded for approximately half of the worldwide electricity supplies to reduce CO2 emissions by 2050‚ which it is estimated by The International Energy Agency (Cited in Shi 2010). This essay will focus on two forms of renewable energies which are solar

issues in today’s world is that of energy sources to power an increasing global demand. Traditionally‚ humans have converted energy from natural resources like coal and natural gas for use. However‚ these sources of energy are both nonrenewable and cause large amounts of pollution. As we progress through the 21st century‚ renewable energy sources like solar and wind energy will see increased use to replace traditional sources. One of these sources‚ wind energy‚ is seeing a rise in development because
