Renewable energy is energy that comes from a natural source of activity on Earth that is not depleted when used. There are a few sources of renewable energy sources that humans have put into use since the twentieth century; solar energy, hydroelectric energy also known as hydropower, and wind energy. According to National Geographic, “Solar energy is the technology used to harness the sun 's energy and make it useable” (Solar Energy 5). Today from all of the energy humans use about one-tenth of the energy comes from solar power. “Wind is the movement of air from an area of high pressure to an area of low pressure” (National Geographic “Wind Power” 5). Wind power is produced by large wind turbines that slowly rotate by the wind blowing upon them. One wind turbine had the potential to power about 600 homes. Another form of important energy that is renewable is hydropower which is “ electricity generated using the energy of moving water” as stated by National Geographic (“Hydropower “ 5). About one-fifth of the total energy Humans use comes from hydropower. Altogether these forms of renewable energy supplies about 60 percent of the world 's power.

Solar power has made a huge impact on the world by supplying energy that is environment friendly and harmless to nature. Solar energy comes from the sun, therefore the main raw material in solar energy is free. Also, the sun is known to be harm free to humans and animals because their is no destruction needed for the sun to shine. Wind power has also made an incredible impact on Earth. Wind power supplies energy to the world that is also environment because there is no form of pollution involved with the wind. The main raw material of wind energy is free which is wind, and the wind c...

...5) The water is run through a turbine that spins and when the turbine spins it conducts electricity. Wind power is power that come from the flow of wind that is “caused by the sun unevenly heating the Earth”( “Wind Power” 5).

Most of the world’s current energy supply comes from the use of renewable energy sources. About 60 percent of the world’s energy comes from Solar, WInd, and Hydroelectric energy. Renewable energy sources also supplies jobs to many people around the world. Renewable energy sources also reduces harmful materials released into the atmosphere, making it and environmental friendly energy source. Renewable energy sources has made an impact the world forever by supplying energy to humans cheaper, healthier, and environmental friendly. Renewable energy sources will continue to improve and change the face of the planet for more centuries to come.

Essay about Renewable Energy Source For Solar Energy

- World is moving fast towards rapid use of renewable energy source that will generate scarcity one day. On the other hand, solar energy is considered to be highly dependent renewable energy source which is not yet tapped very effectively. Solar energy can be utilized in multiple ways through either creating thermal energy or converting it into electrical energy. The solar power growth has witnessed significant presence since 2007 while moved from 3.1 (gigawatts PV manufacturing) in 2007 to 50 (gigawatts PV manufacturing) in 2014 (Chu, 2011)....   [tags: Photovoltaics, Solar cell, Solar power]

Renewable Sources Of Energy Such As Wind Or Solar Essay

- As I progressed through this assignment, I realized that I did not use any renewable sources of energy such as wind or solar. Most of my energy was sourced from the use of fossil fuels, with the primary source for heating my home being natural gas and as I researched further, I found that my electricity source was provided by the Martin Drake Power Plant located in Colorado Springs. This is a 254 megawatt coal-fired power plant and provides 1/3 of the electricity to Colorado Springs (Colorado Springs Utilities, 2016)....   [tags: Fossil fuel, Wind power, Renewable energy]

Renewable Energy : Solar Or Wind Power Essay

- The Renewable Energy That’s Not Talked about We hear talk about renewable energy all the time, and how, what options are when it comes to renewable energy. There is one kind of energy that is rarely never talks about. That is Geothermal Energy. Geothermal Energy makes up less than 1% of energy used in America. Why is that when renewable energy is the fad, most people are saying how they want to switch over to renewable energy, but never mention one that is so useful and easy to obtain. The reason I believe why it’s not mention as much as solar or wind power is that most people don’t know what it is or how it can even be consider a renewable energy....   [tags: Wind power, Alternative energy, Energy, Peak oil]
