The resources that can be recovered back naturally to its form are known as a renewable resource. For example, we can take oxygen where the humans consume oxygen and give back carbon-di-oxide, then the plants and trees consume that carbon-di-oxide and give oxygen out. Only when the consumption of renewable resource is limited, the resource will be stable, as the process of recovering takes some time than the consumption of resources.
Advantages and Disadvantages of renewable energy sources
- The main benefit of a renewable resource is they will not be out of stock at any time, but if we use the resource in a limitless way then there will be a shortage of resources over a period of time. Hence make sure the proper usage of the resource.
- If we consider solar energy, where we can use the resource and produce electricity. The resource will be free of cost. But the implementation and the maintenance of solar panels will be costly and need more place to implement.
- Let us consider biomass where it comes from animal waste or decaying of plants. Here the biomass products are burnt to give heat or to produce electricity which is also a cheap resource. But the burning of materials may pollute the environment.
- We can take water resource where we can use the resource to produce electricity by circulating the turbine by the force of water. There will be no wastage of the resource and less cost for the resource. More electricity will be produced and more people will get a job by this hydropower electric plant. But the construction of the dam with turbine will cost more.
- The resource like air will be used to create electricity by moving the wings of turbines in the windmill, but we need more area to construct the windmills and the cost of construction and implementation will be more.
