Catching the wind
- Moving air carries energy we can capture.
- A wind turbine 风力涡轮机 has huge blades on a tall tower.
- The wind spins the blades, which turn a generator.
- Many turbines together form a wind farm 风电场.
捕捉风
- 流动的空气携带我们能捕捉的能量。
- 一台风力涡轮机(wind turbine)在高塔上有巨大的叶片。
- 风转动叶片,叶片转动发电机。
- 许多涡轮机一起组成一个风电场(wind farm)。
The benefits
- Wind is renewable 可再生 and free — it keeps blowing.
- Turbines release no CO2 while running.
- They take little ground, so farms and grazing continue below.
- Once built, the fuel costs nothing.
好处
- 风是可再生(renewable)且免费的——它一直吹。
- 涡轮机在运行时不释放CO2。
- 它们占用很少的地面,所以下面的农场和放牧继续。
- 一旦建成,燃料不花钱。
A wind turbine makes electricity when… · 风力涡轮机在以下情况发电……
Wind spins the blades, which turn a generator inside the turbine to make electricity. · 风转动叶片,叶片转动涡轮机内部的发电机来发电。
The costs
- Wind is intermittent 间歇性 — no wind, no power.
- Output rises and falls, so it needs backup or storage.
- Spinning blades can kill birds and bats.
- Some people find the tall turbines noisy or ugly.
代价
- 风是间歇性(intermittent)的——没风,没电。
- 输出起起伏伏,所以它需要后备或储存。
- 旋转的叶片能杀死鸟和蝙蝠。
- 有些人觉得高大的涡轮机吵闹或难看。
A major benefit of wind power is that it… · 风能的一个主要好处是它……
Wind is renewable and emits no CO2 while running — a clean, free fuel. · 风可再生且运行时不排放CO2——一种干净、免费的燃料。
Because wind does not always blow, wind power is ____ (not constant). · 因为风不总是吹,风能是____的(不恒定)。
Wind power is intermittent — output rises and falls with the wind, so it needs backup or storage. · 风能是间歇性的——输出随风起伏,所以它需要后备或储存。
Where it works
- Turbines need strong, steady wind, not calm air.
- Windy coasts, ridges, and open plains are best.
- Offshore 海上 wind farms catch strong sea winds.
- A sheltered, still valley is a poor place for them.
它在哪里有效
- 涡轮机需要强劲、稳定的风,不是平静的空气。
- 多风的海岸、山脊和开阔的平原最好。
- 海上(offshore)风电场捕捉强劲的海风。
- 一个遮蔽的、静止的山谷对它们来说是差的地点。
Benefit or cost of wind power? · 风能的好处还是代价?
Sort each feature of wind power into a benefit or a cost. · 把风能的每个特点归入好处或代价。
Farmers can still grow crops on the land between wind turbines. · 农民仍然能在风力涡轮机之间的土地上种庄稼。
Turbines take up little ground, so the land around them stays useful for farming or grazing. · 涡轮机占用很少的地面,所以它们周围的土地仍然可用于耕作或放牧。

Wind is renewable, intermittent, and can harm flying wildlife. It needs strong, steady wind, not calm air. · 风可再生、间歇性,能伤害飞行的野生动物。它需要强劲、稳定的风,不是平静的空气。
Wind's big weakness is the same as solar's: it's intermittent. You cannot make the wind blow on demand, so a grid running on wind needs storage or a backup source for calm days. Its wildlife cost is real but local — careful siting away from major bird routes reduces it. Clean and free, but not always available.
风的大弱点和太阳能一样:它是间歇性的。你无法让风按需吹,所以靠风运转的电网在平静的日子需要储存或后备来源。它的野生动物代价是真实的但局部的——把选址小心地避开主要的鸟类路线能减少它。干净又免费,但不总是可用。
A prairie wind farm:
- Tall turbines line a windy ridge; below them, the farmer still grows wheat right up to the towers.
- On a blustery day they power thousands of homes with zero emissions.
- On a still day they barely turn — so the grid leans on stored power or a gas plant until the wind returns.
一个草原风电场:
- 高大的涡轮机排列在多风的山脊上;它们下面,农民仍然把小麦一直种到塔跟前。
- 在刮大风的日子里,它们零排放地给数千个家供电。
- 在平静的日子里,它们几乎不转——所以电网依靠储存的电或一座燃气电厂,直到风回来。
A wind turbine turns the wind's energy into electricity; many form a wind farm. Benefits: renewable, low-CO2, and the land below stays farmable. Costs: it is intermittent (needs backup), can kill birds and bats, and needs windy sites — windy coasts, ridges, and offshore locations work best.
一台风力涡轮机把风的能量变成电;许多组成一个风电场。好处:可再生、低CO2,下面的土地仍可耕种。代价:它是间歇性的(需要后备),能杀死鸟和蝙蝠,需要多风的地点——多风的海岸、山脊和海上位置效果最好。
