Renewable sources are sources of energy that are found in the planet’s own structure. Found in sunlight, the air, and in the ocean, these natural sustainable sources of energy are being used as alternatives to other more traditional sources like fossil fuels. Renewable energy sources are becoming a more popular means of energy due to the lesser impact they have on the environment. Though they can still be harmful, they create less pollution than if we would continue to use oil and coal. The most sustainable forms of energy are typically harnessed from a natural process. 


Solar Energy

Sunlight can be used as a resource where technology captures solar energy and converts it into heat. It can be used for illumination, heating water, electricity, and even cooling systems. Houses and businesses are using solar panels to collect energy to support the heating and cooling systems within their complexes, as well as, creating a source of hot water. 


Wind Power

Fields of wind turbines are becoming more frequent as people are using the wind flow captured by these turbines to produce electricity. On a smaller scale, wind can also be captured to pump water on farms by using windmills. Depending on the size of the wind farms, determines if the energy is used to power a small community or even a large city. 


Geothermal Energy

This energy comes from the heat the earth emits. Power plants harness the heat sources from the earth to generate electricity. The geothermal energy can heat office buildings, aid in the growth of greenhouse plants, heating water at fish farms, and helping with industrial processes. 



This source isn’t a new energy source. Waterwheels have been around for ages and can be found functioning at historic landmarks and museums. Hydropower is collected by capturing the river’s kinetic energy and then converted into electricity. Dams are constructed to store water until it is ready to be released. Once it is released, the water flows through turbines which then produce electricity. Depending on the location of the waterways, can determine what the captured energy is used for. 


Ocean Thermal and Mechanical Energies

The ocean can produce two forms of energy. The heat captured from the sun creates thermal energy and the motion caused by tides and waves produce mechanical energy. Since the world is comprised of 70 percent ocean, this source of energy is promising for the future as an alternative form of energy. 


These sources are better for the world we live in. We don’t have to lose the comforts of heating and cooling our houses to protect the environment. We only need to change the ways we source energy.
