Energy is everywhere in the world.We use energy every day.There are all kinds of energies in the world,such as hydropower resources,sun's energy,wind power.
Liangshan is called"kingdom of hydropower resources".Jinsha River,Yalong River and Dadu River are just like three great dragons carrying hydropower resources to Liangshan from the
Qinghai﹣Tibet Plateau.The government has planned to build 11large and super hydropower stations on Jinsha River,Yalong River and Dadu River within Liangshan.On the other hand,there is rich wind power in Liangshan.The government is building a large wind power station between Huili and Ningnan.
Electricity is a form of energy,and this is what powers the TV,mobile phone,fridge and more.Our growing need for energy is one of the problems in the world today,because producing electricity also produces pollution.Although energy in Liangshan is very rich,we must do something to protect the environment and save lots of energy.
Here are some simple ways to make a big difference when we're using electricity.
On or off?Leaving TV and computers on with the little red light showing still uses electricity,even though they might look like they're turned of.To stop this,you can turn them off.
Light out!Turning light off when you're not in the room can save a lot of energy.
Fridge door closed.Try not to leave the fridge door open or put hot things inside when you used the fridge.Because it takes a lot of energy to keep cool.
Use the sun's energy.An increasing number of people are fitting solar panel to their houses.They create electricity from sunlight.which can then be used to make hot water or do the cooking and so on.
