Questionsarebasedonthefollowingpassage.
Critics of renewable energy often argue that wind and solar power are "boutique" ( 精品店) energy sources that could never 1 the world's energy needs, but one newreport has found that solar power could 2 all of the energy needed in many parts ofthe world. The report, which was produced by World Wildlife Fund (WWF), along withFirst Solar,3TIER and Fresh Generation, found that in seven case studies, less than 1percent of3 land mass would be required to meet 100 percent of projected electricitydemand in 2050, demonstrating that solar power is indeed a feasible energy source inmany parts of the world.
The new report, Solar PV Atlas: solar power in 4 with nature, finds that solarenergy production doesn't have to be at odds with environmental conservation. Forthe study, WWF and its partners looked at Indonesia, Madagascar, Mexico, Morocco,South Africa and Turkey. Although they represent diverse populations and 5, thosecountries and regions all have one thing in common: they all receive 6 sunshine. Butsunshine isn't the only thing needed to produce solar energy; government policies thatare7(or at least open) to renewable energy are also necessary, and "there is room foroptimism in each of the selected regions," according to the report.
In 2010,16.7 percent of global energy 8 was produced by renewable sources,but solar accounts for just 0.1 percent of total global electricity generation. The reportacknowledges that it's unlikely that all of the electricity in any of those countrieswill come 9 by 2050, but it says that the "100 percent" scenario would be possiblewith 10 disruption to the environment. What would be more feasible, the reportsuggests, would be to provide somewhere in the neighborhood of 30 percent of globalelectricity production from solar by 2050.
