What are some examples of renewable energy?London, Britain at nightA grizzly bear and her cubs walkalong an oil pipeline in PrudhoeBay, Alaska. Our use of fossilfuels is impacting the environment in a variety of ways.Wind turbine
7、s at MiddelgrundenWind Park in Copenhagen, Denmark provide a renewable form of energy. Many countries are using renewable forms of energy such as wind, hydroelectric, and solar power.I see electric lights in London, as well as cars and boats that use gasoline and oil. I also see an oil pipeline with
8、 bears walking on it, and turbines that use wind energy to produce electricity. In the pie charts, a number of other kinds of energy are mentioned, including natural gas, solar and geothermal energy, nuclear and hydroelectric energy, and biomass.When we burn fuel for energy, it sends pollution into
9、the atmosphere, and over time, it is changing Earths climate. On the other hand, using cleaner, renewable forms of energy reduces those negative effects on the environment.Renewable energy include wind energy, solar energy, hydroelectricity, geothermal energy, and bioenergy, etc.B | Look at the pie

How much of the worldsproduction of renewable energy comes from wind power?These pie charts show the worlds production of renewable and non-renewable sources of energy. Each section represents a different source of energy. The numbers show what percent each source of energy makes up of all energy production.The world gets 38 percent of its energy production
