Green Power
You’ve insulated the attic, installed triple-glazed windows, and bought high-efficiency appliances. Can you make your home any more eco-friendly? For an increasing number of Americans, the answer is yes. You can let nature help cut your utility bill. It may be as simple as replacing outdoor lights with solar-powered fixtures or signing up for your utility’s "green power" program. Thanks to rapid improving technology and government subsidies, thousands of Americans living in remote locations are finding it can be cheaper to use the sun and wind than fossil fuels.
However, don’t cut your ties to the local utility just yet.
(A)While renewable energy won’t replace coal and natural gas soon (or ever, critics contend), consumers have more choices in their energy mix than ever before.
(B)And they’re not at all whole-bran environmentalists: Roldan Montalvo runs a gas station here in Hebbronville, Texas.
(C)But when he wanted to bring electricity to his cabin eight miles out of town, he went solar. The reason was simple. The utility company wanted $100000 to extend its electric line to his cabin.
(D)Mr. Montalvo paid less than $8000 for his solar system, "It’s all right so far," he says, looking up at the three solar panels that run a few lights, a fan, and a TV inside. "I can run power tools."
Others, of course, take a more enthusiastic line. "There is a new focus on renewable." says Thomas White, chairman and chief executive of Enron Renewable Energy Corporation, which has completed the world’s largest wind farm in Minnesota. "My feeling is that we are at the point in time where the personal computer was in the late 70s," adds Mac Moore, Director of Business Development for BP Solar, one of the largest manufacturers and marketers of solar electric systems in the world. "Over the next 10 years, if things go well, there’s going to be a revolutionary change in the way that we obtain power."
Wind power represents an even more compelling argument for remote homeowners. Turbines have become so much more efficient over the past decades that homeowners a quarter mile from a utility line may find it cheaper to put up a wind turbine than to pay the utility to extend its service. But for most consumers, barriers remain. For one thing, renewable energy systems are expensive to install and require more than a decade before consumers see a payback.
Even a good deal on solar panels in a high-sun area would still cost a typical homeowner 30 cents a kilowatt hour, explains the CEO of Strategy Unlimited, a technology-research firm in Mountain View, Calif. That’s far above the 6 to 15 cents that Americans typically pay their local utility, he adds. Small-scale wind turbines are much more competitive—anywhere from 8 to 15 cents a kilowatt-hour, says Mike Bergey, President of Bergey Windpower in Norman, Oklahoma. But they still require a $30000 to $35000 investment up front and it would take most homeowners 15 to 20 years before they’d see any payback.
There are other drawbacks. Since these systems only produce energy intermittently, there’s no guarantee homeowners can store enough energy to run their homes when the sun isn’t shining or the wind isn’t blowing. Then there’s aesthetics. Will the neighbor accept those solar panels on your roof? Do you want a 100-foot-high wind turbine humming in your backyard like a muffled helicopter? That’s why companies like Bergey Windpower are targeting rural residents in the United States—especially those in states such as California, where the government will pay up to half the cost of installing renewable-energy systems. [br] It can be inferred from the passage that more people will ______.
选项
A、use non-renewable and renewable energies
B、stick to the use of local utility as before
C、not use any renewable energies at all
D、use renewable energies for household only
答案
A
解析
本题为事实信息题。题目问:根据文章的叙述,我们得知更多的人将要做什么?从“While renewable energy won’t replace coal and natural gas soon (or ever, critics contend), consumers have more choices in their energy mix than ever before”可知,在可再生能源代替常规能源之前,人们是混合使用各种能源的,所以选A。
