Understanding Renewable Energy Sources
By Ms. Melisa
Energy sources classified as renewables are those that can be easily, regularly, and naturally obtained. Energy is needed by vehicles on the road to run their engines, and this energy is usually obtained from fuels based on crude oil, such as gasoline. Kerosene and liquefied petroleum gas (LPG), both of which come from crude oil, are commonly used in household cooking. Electricity is produced primarily from non-renewable resources, such as coal, and is necessary for many daily tasks. Although it takes millions of years for coal and petroleum to develop, humans remove them massively and quickly, increasing the risk of their depletion. We require renewable energy, also referred to as alternative, natural, and sustainable energy sources, to address this. When compared to non-renewable energy sources like coal, oil, and gas, these are more ecologically friendly. Wind, sun, and water are just a few of the renewable energy sources that are available in Indonesia.
Wind
Wind turbines are used to capture wind power and use it to rotate generators and other turbines. These generators transform rotational energy into electrical energy, which is then delivered to the general public via power networks. Wind farms are colloquial terms for wind-generating plants.
Sun
Photovoltaic power plants use solar panels to create solar energy. The only energy source needed by solar power plants is sunshine, which is plentiful and practically limitless.
Water
Building dams to generate reservoirs is the process of producing hydropower, a significant source of electricity in Indonesia. These reservoirs are purposefully shaped to release water at a rapid pace, which powers turbines that are linked to generators to generate power.
Benefits of Renewable Energy
The use of renewable energy has various benefits for human life, such as:
- preservation of the environment by cutting down on air pollution and limiting ecological harm.
- Because these energy sources are naturally abundant, production costs are reduced.
- promoting local self-sufficiency and minimizing reliance on energy sources that are primarily imported.
