• Since the discovery of fossil fuels, it has been very widely used. (Oil,coalnergy structure, fossil fuels accounted for almost 90%,both in China and all over the world.
Energy and Environment
• While we are developing clean and renewable energy resources ,we have to save ,save water , paper , electricity and so on . Because all of these consume the limited fossil fuels . We don’t only save for money , but also for a better environment . When We Put the Environment First, Development Will Last .
Energy and Environment
• World Wide Web of life
