Energy
The search for alternative (选择性)
sources of power,
such as these windmills near Palm Springs, Calif., that
are used to generate electricity, has been vigorous
(有力的)
since the energy crisis (危机)
of the 1970s.
Wind is a renewable source of energy and has been utilized (利用)
by humans for generations.
Wind
currently produces a small amount (>1%) of total U.S. electricity
demand. Wind has the potential (潜力)
to meet a
much larger share of the nation’s electricity demand in the future.
Wind energy is clean energy;
windmills produce no air or water pollution. The blades (刀刃)
of wind machines have been known to affect bird populations and can
produce noise pollution.
