Renewable energy is a term that refers to various forms of energy naturally obtained and replenished from the environment. They include geothermal, solar, wind, biomass and hydro power energy. These sources are referred to as renewable because, in theory, they will never run out. Renewable sources currently supply about 10-20 % of the world’s energy. Unlike other sources, renewable energy has contributions to the environment, health sector, and the economy.
The most significant advantage of renewable energy is its sustainable nature. Unlike conventional energy sources like coal and gas, they will never run out. In some circumstances, the renewable energy sources are more reliable compared to other electricity forms. For instance, if a grid breaks down photo voltaic powered generators can supply electricity automatically (Owusu, et la.,2016). Adding battery storage to the system enables the supply of electricity even when the sun goes down and on stormy days. These energy sources originate and adapt to natural cycles, thus their name “renewables”. This makes them essential in a sustainable energy system that allows development without risking subsequent generations.
Further, renewable energy sources are indispensable partners in the fight against climate change. They are the cleanest and most viable solution because they do not emit greenhouse gases in the energy generation process(Panwar, et la.,2011). Particularly, they contain little waste products like carbon dioxide and chemical pollutants. Consider solar energy, for example, light energy from the sun is converted directly to electricity through photovoltaic without procuring any greenhouse gases. Similarly, wind power energy relies on moving air for conversion into electricity without polluting the environment.
Moreover, the indigenous nature of the sources reduces the energy dependence of economies. A penitent point to note is that dependence on fossil fuel imports results in subordination to the economic and political short-term goals of the supplying country. These include the security of the energy supply. Some political and social events disrupt the energy market and risk the supply of energy deposits. Thus, renewable energy resources reduce the exposure to the risk of depending on other energy sources that must be imported to meet demand. There exist renewable resources to produce sustainable energy almost everywhere in the world.
Besides, renewable sources of energy play an important role in regional development. Notably, they can revitalize various rural communities. For instance, wind turbines and solar panels produce energy that provides rural areas with tax revenue. Moreover, farmers can lease their spaces to wind developers and gain income from the turbines. Further, renewable energy production provides employment opportunities for skilled individuals. The labor areas include installation, maintenance, planning, and logistics.
Also, renewable energy sources promote improved general health. Most coal and gas plants promote water and air pollution that is linked to various health hazards like breathing problems. In contrast, wind, solar and hydrodynamic systems produce electricity with no associated air pollution emissions. Also, geothermal and biomass systems emit lower pollutants compared to coal and gas powered plants. Additionally, wind and solar energy do not require water to operate and thus, do not contribute to the pollution.
Collectively, renewable sources of energy have undeniable impacts in today’s world. They have improved our health, the environment, and the economy. Moreover, they have contributed to energy reliability and resilience. It is critical to develop and promote renewable energy supply technologies to reduce the irreversible effects of non-renewable energy sources.
