However,fossil fuels make pollution.This is bad for the Earth.Fossil fuels are also nonrenewable.Some day they will be gone.So,scientists 2 want people to use green energy.Why is green energy important?First,it is clean.It doesn’t hurt the Earth.Next,it is renewable.It won’t run out. Green energy gives us almost 25% of the electricity we use today. What are the main sources(来源) of green energy? Water Power 　　Water power uses moving water in rivers and dams(堤坝).Moving water has energy.Water power makes 16.6% of the electricity we use. Wind Power 　　Is wind power new?No,it isn’t.People used wind power many years ago.Wind power makes 4% of the electricity we use. 3 Solar Power 　　Solar power comes from sunlight.The sun shines on solar panels (太阳能电池板),and electricity is made.Solar power is now as cheap as some fossil fuels.It makes 1.5% of the electricity we use. Biomass energy(生物质能) 　　Biomass energy is that we get from plants around us.For example, dead wood or grass is burned in power stations.This makes electricity. Biomass is green energy because we plant new trees or crops(庄稼) after we use it.Biomass makes 2% of the electricity we use. New Green Energy 　　The ocean rises and falls each day.This moving water can make electricity. We call it tide power.There is also heat under the Earth’s surface. Scientists can use this heat for energy,which is called heat power. We may find other sources of green energy in the future. 　　Some day,green energy could make 100% of the electricity we use. That’s good news for the Earth! 1.How do we get most of the electricity nowadays? ____ A.Through fossil fuels. B.Through green energy. C.Through o
