Renewable Energy

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment. While there are many different types of renewable energy sources, wind power and water power are two of the most popular, only surmounted by solar power. The use of wind power and water power is popular because they are actively found throughout the world and readily available for use.

Wind power is a commonly used renewable energy. Wind power produces no methane or other greenhouse gasses while in operations, which makes it a popular source of renewable power. Wind can be used to operate wind turbines, which are especially very popular in the commercial arena. The main issue with wind is that it is not constant, thus it tends to be less energy producing than solar power. In addition to consistency, wind turbine farms generally require significant space for construction and operation. Even though it is not as popular or as efficient as solar power, wind power is believed to be able to produce more than five times the amount of global energy used.
