Sally Kemmerer has,so far,escaped Northern California’s rolling blackouts.
But up on the roof for her Oakland home,workers are tapping into,perhaps,the most reliable power source,the sun. It could mean no more worries about blackouts or power rates.
Sally Kemmerer,homeowner says,"I hope that we’ll be able to zero out,you know,our electric bill. I mean that’s definitely our goal."
Turning the sun’ s rays into electricity is,of course,nothing new.
But California’s power crisis has cast a new light on the technology.
Gary Gerber.a solar power contractor,says,"I might have been getting,say three phone calls a week a couple of months age. I’ m getting six a day now.it’ s completely crazy."
Alternative energy is even more attractive,thanks to a state rebate program. So far this month .California’ s energy commission has received 200 project applications. That is more than the number of applications all last year.
Putting in a solar roof is still a relatively expensive proposition. This project cost around 45,000 dollars. Even taking into account the state subsidy of 12,000 dollars,that leaves a net cost to the homeowner of around 33,000 dollars.
Sally says, "We were happy to find out that,eventually,the system should pay for itself,you know 20-years, maybe."
Aaron Wellendorf has had a p-v(or photovoltaic generator)for more than a year. Like most solar systems,his is not off the grid completely the utility still kicks in at night,or when there’ s no sun. But when there is bright light,things change.
Wellendorf says,"I’m turning my meter backward with extra power that I’m generating." Backward? That’s right! Wellendorf’s meter tracks how much power goes back into the utility grid. Last year all the paid for electricity was a service charge. That charge was around five dollars a month.
In fact,even after powering his super-efficient household appliances and his converted electric track, Wellendorf generated a net surplus of more than 2000-kilowatt hours.
Unfortunately,state law doesn’t require the utility to pay him for that. Wellendorf says,"I don’t get it in money, I just get the satisfaction of helping out the power grid."
And,he gets the satisfaction of being energy self-sufficient. [br] According to the article,the California energy commission has received 200 project applications in one month. If that rate continues,approximately how many applications will they receive his entire year?
选项
A、2,400
B、1,200
C、200
D、3,600
答案
A
解析
从题中可知,一个月收到了200份申请,按照这个比率计算,一年将收到200x12=2 400份申请。因此正确答案为A。
