A renewable energy source is a sustainable source that is obtained from inexhaustible resources. Rapid industrialization, depletion of non-renewable energy and an increasing concern for the environment has encouraged a man to explore new ways of creating energy that will last for generations. Solar smart battery, biomass, wind, geothermal and hydrogen sources are some of the common renewable energy sources being utilized today. The biggest advantage is that these sources will never deplete and can be used without causing harm to the environment. Here are the most effective renewable energy sources:
From powering residential homes to entire industrial areas and remote operations, solar is among the most popular renewable energy sources. The concept of harnessing the power of the sun is not new; solar power has produced energy in the form of heat and light for a long time. The great thing about solar energy is that it does not produce harmful emissions. The process of converting solar to power requires photovoltaic devices like a smart battery which converts to electricity. Solar can be used to power anything as small as a calculator to something as large as an industrial unit. Solar PV power plants can supply electricity to homes and businesses.
Biomass is derived from the natural carbohydrates that occur in organic matter such as trees, crop waste, algae and various agricultural by-products. This energy can be used for fuel, power and products that have been traditionally powered by fossil fuels like plastic, glue, toothpaste and artificial sweeteners. It is generally used in power plant operation. When bio-energy is burned, steam is produced and powers a turbine. The turbine works the generator which converts the power into electricity. Biomass is environmentally friendly and a reliable, functional energy source.
Wind power is one of the oldest methods of harnessing energy. The conversion was used to propel boats and windmills, but today it is used to generate electricity. Wind energy is abundant. Wind, like solar, is becoming more cost-effective with research being conducted all the time to cut costs and enhance efficiency.
Geothermal refers to heat from the earth, resources range from hot water and rocks found beneath the Earth’s surface. It can be used for hot water and can generate electricity through hot rock. Although quite costly, it is used in over 70 countries for heating. Hot springs are considered geothermal energy, the water can be pumped directly into a home or application to heat buildings.
Hydrogen is a simple element that is also abundant on earth and can be converted into energy. A fuel cell combines hydrogen and oxygen to produce electricity, heat and water. Hydrogen fuel cells are about 20-30% more efficient than gas engines. The biggest challenge for the automobile industry is its dependence on petrol which pollutes the earth. Hydrogen fuel cells as internal combustion engines can reduce the dependency on petrol and its impact on the environment.
