As long as we live, and the private and public entities thrive, we will require energy sources to meet our diverse needs. With the energy sources fast getting used up for commercial and domestic purposes, educational institutions and government agencies are turning towards renewable sources of energy to meet the growing demands. With advanced use of technology, we are now able to use solar and wind power to produce energy. Here are the top 5 types of renewable energy that have the potential to shape our tomorrow.
#1. Solar energy
This is perhaps the most popular of all renewable energy types, and the most significant advantage is that the energy comes directly from the sun and there will be no shortage in supply as long as the sun shines in the sky. With solar panels installed over rooftops of homes or commercial buildings, the sun’s energy can be tapped and converted into electricity that powers homes and companies. Solar energy may soon be used for a variety of other things as this is an eco-friendly solution saves the environment and money too!
This term is used for renewable energy generated from moving water when it runs through turbines to produce high energy, thus producing electricity. This energy is often formed naturally at waterfalls or is humanmade with dams when water falls from an elevation. Examples are hydroelectricity generated at Niagara Falls on the NY-Canada border and Hoover Dam built on the Colorado River. This most significant advantage of Hydropower is that this is a non-polluting source of energy without any harmful emissions.
#3. Wind power
Just like hydroelectricity is created from falling water, wind energy can be generated by blowing wind. The power of air can be captured in the massive turbines that are used to generate electricity when the turbine spins. While this is not a realistic option for homeowners, wind power generated by wind farms is becoming increasingly popular in the utility-scale applications. In 2017, wind dams alone produced about 60% of the electricity used in the United States.
#4. Renewable Natural Gas
Renewable Natural Gas is fast becoming a safer and healthier option to fossil fuel. Also known as Sustainable Natural Gas or biomethane, it is actually a form of biogas that is upgraded to the characteristic of fossil-derived natural gas having a methane concentration of 90% or above. Biogas is a gaseous form of methane that is mainly obtained from the biomass, waste of living organic matter similar to plants or animals. Fuels such as ethanol and biodiesel that are used in cars and trucks usually come from biomass energy.
#5. Geothermal energy
Our planet that we live in has a massive source of energy contained within it. The heat produced and trapped at the time of the formation of the earth, combined with the heat emissions from radioactive decay caused in the rocks beneath earth’s crust resulting in high amounts of geothermal heat energy that is often released through volcanic eruptions. Geothermal energy may be captured to generate electricity used for heating or cooling the buildings. In Iceland, geothermal energy accounts for 90% of the energy used for heating homes and offices, while 25% of electricity needs of the country come from the geothermal sources.
