為甚麼節約能源能有助保護環境？

例如開小D冷氣機會減少所排出既廢氣..
因為D廢氣會周圍傳..令空氣變得更壞..
同埋有好多電器都會..
所以節約能源能有助保護環境..*

energy saving helps to protect our environment because
- less consume energy, so less natural resources going to be used for production of energy
- less consumption of energy in power plant as well
- reduce CO2, SO2 and suspended particles production from power plant
- e.g. use energy for electronic appliances, heat energy will be produced --> warmer the room temperature at least, then u may turn on a fan to cool down the room temperature. It increases energy in usage.
- e.g. light pollution. A lot and strong Neon light at night time. It will mess around the life cycle of some creatures apart from big consumption of energy
