Environmental Policy and Education
Staggering amount of fossil fuel is consumed continuously and fuel scarcity will come to an end soon. Moreover, burning fossil fuel emits greenhouse gas and atmospheric pollutants. Therefore, it is important to find alternative clean energy sources such as renewable energy. Unlike conventional energy sources, renewable energy is abundant in the environment and can be replenished by the natural process so that they can be reused again. Some of the renewable energies are as follows:
When sunlight is irradiated on the solar panel, delocalized electrons will be excited. Direct current will be produced when it is connected to a closed circuit. A current inverter needed to be added to transform DC to AC.
Wind power is the use of natural wind to initiate the rotation of windmills or wind wheels. This momentum will drive the generator to produce direct current. A current inverter can be added to transform DC to AC.
Hydroelectric is the use of water flow and the difference in potential energy to drive a turbine generator directly in order to produce electricity. The larger amount of water flow or larger difference in potential energy can result in a larger amount of electricity being generated. However, the application of hydropower is also limited by its geographical location. It can only apply in the big river such as the Yangtze River.
To acquire a balance between environment, economy and society in order to meet the needs of the present without compromising the ability of future generations to meet their own need, sustainable development is of utmost importance. Therefore, it is necessary to educate the next generation and raise their environmental awareness. We also put our effort on environmental education.
