The second significance for the renewable energy is of course the climate change issue as well as the pollution

23、 control. But when the financial crisis comes up, I think renewable energy has a new meaning in it. We use the renewable energy to fight against economic slow-down and we provide and create new jobs through the development of new renewable energy.Task 4 Vocabulary PreviewRead the words and phrases b

26、rural and remote areas, where energy is often crucial in human development. Globally, an estimated 3 million households get power from small solar PV systems. Micro-hydro systems configured into village-scale or county-scale mini-grids serve many areas. More than 30 million rural households get ligh

27、ting and cooking from biogas made in household-scale digesters. Biomass cook stoves are used by 160 million households.2.Harnessing energy from human movementsThe human body contains enormous quantities of energy. In fact, theaverage adult has as much energy stored in fat as a one-ton battery. That

28、energy fuels our everyday activities, but what if those actions could in turn run the electronic devices we rely on? Today, innovators around the world are banking on our potential to do just that.Movement produces kinetic energy, which can be converted into power. In the past, devices that turned h

29、uman kinetic energy into electricity, such as hand-cranked radios, computers and flashlights, involved a persons full participation. But a growing field is tapping into our energy without our even noticing it.Consider, for example, a health club. With every step you take on a treadmill and with ever

30、y bicep curl, you turn surplus calories into motion that could drive a generator and produce electricity. The energy from one persons workout may not be much, but 100 people could contribute significantly to a facilitys power needs. Beyond body-powered gyms and dance clubs, ideas are also in the wor

31、ks to provide electricity for more ordinary, useful things. Researchers are creating ways to power small mobile devices like cellphones, MP3 players and laptops when there is no access to conventional energy sources. Soon, we might not even have to consciously move to create power. Scientists are working on a polymer film that would surround power-generating fibers and allow them to be implanted into
