What Are Renewable Energy Sources
What are renewable energy sources? These are energy sources that are naturally occurring resources capable of generating clean energy and those which can replenish themselves within a short span of time. With the natural non-renewable resources being depleted from the face of the earth there is a demand to recognize and harness the power of renewable energy sources. They are available round the world and can be used to meet the energy needs like heating or cooling as well as running electrical utilities and so forth. The two well known sources of renewable energy are the sun and wind. There are many forms of renewable energy around us like hydropower, biomass power, geothermal power and others. The power of all such energy sources can be combined in order to cut down our dependence on fossil fuels like coal, oil and gas as well as reduce the harmful pollution that they have caused to our environment for centuries.
Instances Of Wind And Solar Power
Two of the most discussed sources of energy are wind and solar power. These are often termed the most discussed and potential sources of renewable energy.
- Wind turbines can be seen on many ridge lines in many countries. Here the energy that is generated is transferred to the electricity service providers
- Solar power is made use of by installing photovoltaic arrays. These are placed either on the rooftops as well as in the form of free standing panels. These panels work by absorbing the rays of the sun and the energy generated is stored in batteries
- Some people have been able to stop the use of any kind of electrical utility service since they have installed solar panels in their homes or even their businesses
Hydro Power
Another form of renewable energy source that promises to hold a lot of potential in the sphere of generation of energy is hydropower. It is a great option. Many governments and organizations have built turbines as well as dam on rivers where the energy of the water flow is captured through the rotation of the turbines. Tidal power is another example of harnessing the power of the flow of water. The turbines are installed in places where the tide goes in and out and energy is captured in such ways. This is a method that is least disruptive to the ecosystems as compared to dams which has altered the composition of many rivers. Generation of hydro power is less dependent on specific forms of weather conditions.
Challenges
However, the energy sources can be trapped in ways to make the energy generated sustainable and consistent through the years. In such ways different forms of renewable energy sources are harnessed. These lead to energy efficiency as well and bring back balance in the ecosystem. Green energy consultants and economists are playing a role in such businesses to help companies structure their infrastructure round such energies and drive profitability out of such ventures.
