問題詳情

V. Reading Comprehension
For generations, we have consistently underestimated
our capacity for innovation. There was a time when we
worried that all of London would be covered with horse
manure because of the increasing use of horse-drawn
carriages. Thanks to the invention of the car, dung disaster
averted. In fact, would-be catastrophes have regularly been
pushed aside throughout human history, and so often
because of innovation and technological development.
Think of the debate over cutting emissions today. Instead of
single-mindedly trying to force people to do without
carbon-emitting fuels, we must recognize that we won’t
make any real progress in cutting CO2 emissions until we
can create affordable, efficient alternatives. We are far from
that point today: much-hyped technologies such as wind
and solar energy remain very expensive and inefficient
compared with cheap fossil fuels. Current technology is so
inefficient that, to take just one example, if we were serious
about wind power, we would have to blanket most
countries with wind turbines to generate enough energy for
everybody, and we would still have the massive problem of
storage. We don’t know what to do when the wind doesn’t
blow. Making the necessary breakthrough will require mass
improvements across many technologies. (from Newsweek,
June 20, 2011)
