Renewable energy is harnessed using natural, renewable resources such as wind, water, and the sun. Solar energy from the sun, hydroelectric power from the water, and wind power are all becoming more common sources of power around the world. Every year the percentage of homes and businesses that run off these renewable resources increases.


Wind power is one of the fastest growing forms of renewable energy sources in the world. This type of power harnesses the intense force present in the wind through the use of turbines. Generally the turbines are grouped together in massive fields known as wind farms, sometimes located offshore. Wind power currently accounts for about 1% of global energy consumption. As of 2011, the Empire State building in the United States, one of the largest buildings in the world, has been set up to run completely off wind energy.


Solar power, another form of renewable resource energy, remains one of the most discussed forms of energy alternative, primarily because it is more readily accessible to the average consumer than wind power. Currently, solar electricity makes up less than 1% of global consumption. Some studies suggest that by 2025 solar power will account for up to 10% of American energy consumption. In the past 8 years, the increase in consumers utilizing this form of alternative energy has increased by around 40% each year.


Finally, there is hydroelectric energy, which has been used for over a century in some parts of the world. This is the type of energy that is used by harnessing the power of water through the use of dams. This type of electricity holds the distinction of being the most utilized form of renewable resource electricity in the world, accounting for 20% of global consumption. Massive dam systems can be found in the Tasmania, China, and in certain parts of the United States such as Niagara Falls and Arizona.


As fossil fuels become scarcer, the demand for renewable resources of power will grow. It is quite likely that within the next 100 years, alternative energy sources that are gathered from the wind, water, and sun will come to account for most, if not all, of global energy production. In addition to ensuring that electricity remains a plentiful resource for the world, this will also help to reduce pollution and decrease the effects of global warming.


About the Author: Norman Heslop firmly believes that renewable forms of energy will play an integral part in future power usage in the United States and beyond. When not looking for ways to reduce the effects of global warming and increase our sustainability as a nation, Norman Heslop enjoys traveling to locations like Niagara Falls and Mexico.
