Besides climate change, developing countries like China need to deal with energy【21】and environmental issues: the development of sources of clean energy needs to be【22】line with their interests. Clean energy has been given greater prominence than ever before; it is seen as a new industrial【23】and【24】of economic growth for the new century. The time for clean energy has come.In China, clean energy is moving ahead at full speed. Take wind power as an example: by the end of last year, China had【25】wind power generating capacity of 12. 21GW, making China the largest wind power generator in Asia and fourth in the world. But according to the research, one-third of wind power capacity is running【26】due to an inability to get the power to the national【27】.India-like China—relies【28】on coal for its energy needs. This will only change if the funds and technology to develop clean energy, such as wind and nuclear power, are【29】. India will not choose clean energy【30】. Nuclear power is currently the most【31】of clean energy sources.【32】, if it is to be【33】on a large scale by developing nations, technological advances will be needed to make it competitive with coal.Compared【34】developed countries, developing countries have more【35】choices when it comes to energy structure.

California Gives Green Light to Space Solar PowerEnergy beamed down from space is one step closer to reality,now that California has given the green light to an agreement that would see the Pacific Gas and Electric Company buy 200 megawatts（兆瓦）of power beamed down from solar-power satellites beginning in 2016.But some major challenges will have to beovercome if the technology is to be used widely.A start-up company called Solaren is designing the satellites,which it says will use radio waves to beamenergy down to a receiving station on Earth.The attraction of collecting solar power in space is the almost uninterrupted sunshine available in geo- synchronous（与地球同步的）orbit. Earth-based solar cells , by contrast , can only collect sun light during day-time and when skies are clear.But space-based solar power must grapple（努力克服）with the high cost per kilogram of launching things in- to space,says Richard Schwartz of Purdue University in West Lafayette,Indiana."if you're talking about it being economically viable for power of the Earth,it's a tough go,"he says.Cal Boerman,Solaren's director of energy services,says the company designed its satellites with a view to keeping launch costs down."We knew we had to come up with a different,revolutionary design,"he says. A patent the company has won describes ways to reduce the system's weight,including using inflatable mir- rors to focus sunlight on solar cells,so a smaller number can collect the same amount of energy.But using mirrors introduces other challenges,including keeping the solar cells from overheating,says Schwartz."You have to take care of heat dissipation（散发）because you're now concentrating a lot of energy in one place,"he says.According to the company's patent,Solaren's solar cells will be connected to radia-tors to help keep them cool.Though Boerman says the company believes it can make space-based solar power work,it is not expec-ting to crowd out other forms of renewable energy.Laws in California and other states require increasing use of renewable energy in coming years,he points out."To meet those needs,we're going to need all types of renewable energy sources,"he says.Solaren is going to design 200 solar-power satellites.A:RightB:WrongC:Not mentioned

Text 2 While fossil fuels—coal，oil，gas—still generate roughly 85 percent of the world’s energy supply,it's clearer than ever that the future belongs to renewable sources such as wind and solar.The move to renewables is picking up momentum around the world：They now account for more than half of new power sources going on line.Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources.But increasingly the story is about the plummeting prices of renewables，especially wind and solar.The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.In many parts of the world renewable energy is already a principal energy source.In Scotland，for example，wind turbines provide enough electricity to power 95 percent of homes.While the rest of the world takes the lead，notably China and Europe，the United States is also seeing a remarkable shift.In March，for the first time，wind and solar power accounted for more than 10 percent of the power generated in the US，reported the US Energy Information Administration.President Trump has underlined fossil fuels—especially coal—as the path to economic growth.In a recent speech in Iowa，he dismissed wind power as an unreliable energy source.But that message did not play well with many in Iowa，where wind turbines dot the fields and provide 36 percent of the state’s electricity generation—and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.The question“what happens when the wind doesn’t blow or the sun doesn’t shine?”has provided a quick put-down for skeptics.But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.The advance is driven in part by vehicle manufacturers，who are placing big bets on battery-powered electric vehicles.Although electric cars are still a rarity on roads now,this massive investment could change the picture rapidly in coming years.While there’s a long way to go，the trend lines for renewables are spiking.The pace of change in energy sources appears to be speeding up—perhaps just in time to have a meaningful effect in slowing climate change.What Washington does—or doesn’t do—to promote alternative energy may mean less and less at a time of a global shift in thought.
It can be learned that in Iowa,_____A.wind is a widely used energy source
B.wind energy has replaced fossil fuels
C.tech giants are investing in clean energy

Google's Solar Energy Gambit（策略）Google is making its largest investment yet in clean energy,setting up a $280 million fund to finance home solar rooftop（屋顶）installations.The search giant announced today it was teaming up with the Silicon Valley's Solar City一a company chaired by Paypal co-founder and Tesla Motors executive Elon Musk一in an effort to break down the biggest barrier to solar energy adoption:the cost."It's a great way to support installations going into more homes,"said Google spokesperson Parag Chokshi.The $280 million fund is the largest fund ever created for residential solar in the United States,according to Solar City,which has raised a total of$I.28 billion in financing capacity during its five-year history.Google over the past several years has invested in large,utility-scale wind and solar,enhanced geothermal（地热）energy,and other renewable energy projects,for a grand total of more than $680 million in the sector. But today's deal is not only Google's largest foray（突袭）into the sector, it is its first investment in distributed energy. Based in San Mateo,California,less than 20 miles north of Google's Mountain View headquarters,Solar City describes itseff as a solar power service provider. The idea is that people want affordable,clean energy一but they often can't afford to buy a photovoltaic system upfront. Solar City is one of a number of companies that have attempted to help people overcome that cost hurdle（障碍）by leasing,instead of owning their rooftop solar systems.Solar City's leases and power-purchase agreements to homeowners,businesses,and schools promise a lower monthly electricity bill(including a set payment to Solar City in addition to utility payments)than customers would get with their usual electricity from the grid.Solar City not only finances these photovoltaic projects,but also designs,installs,monitors,and maintains the systems. Recently,since buying the assets of a company called Business Solutions last year,Solar City has also begun offering energy audits and small home improvements(like installing programmable thermostats)that can make a big difference in energy use.Until now,Solar City has financed most of its 15,000 projects through banks,Chief Executive Lyndon Rive said in an interview. But the problem is only about a half dozen banks are doing solar financing,he said.So in order for Solar City's model to achieve"true scale,"it must"unleash the available capital of corporate America,"he said.Rive is hopeful that Google's move today will set an example for other corporations to make similar investments.

Google's Solar Energy Gambit（策略）Google is making its largest investment yet in clean energy,setting up a $280 million fund to finance home solar rooftop（屋顶）installations.The search giant announced today it was teaming up with the Silicon Valley's Solar City一a company chaired by Paypal co-founder and Tesla Motors executive Elon Musk一in an effort to break down the biggest barrier to solar energy adoption:the cost."It's a great way to support installations going into more homes,"said Google spokesperson Parag Chokshi.The $280 million fund is the largest fund ever created for residential solar in the United States,according to Solar City,which has raised a total of$I.28 billion in financing capacity during its five-year history.Google over the past several years has invested in large,utility-scale wind and solar,enhanced geothermal（地热）energy,and other renewable energy projects,for a grand total of more than $680 million in the sector. But today's deal is not only Google's largest foray（突袭）into the sector, it is its first investment in distributed energy. Based in San Mateo,California,less than 20 miles north of Google's Mountain View headquarters,Solar City describes itseff as a solar power service provider.
