【英语时差8,16】风力农场的科学原理2

 The closer high and low air pressure areas are to one another, the more wind there is. That’s why, for example, coastal¹ areas tend to be very windy. During the day, land heats up more quickly than the sea. So when air over land rises, cooler air over the water blows in to fill the gap². That’s why many wind farms are on the coast. The tops of rounded hills, open plains, and gaps³ in mountains are also good spots. Wind power isn’t a perfect solution, of course. Because even in the windiest places, the wind doesn’t always blow. But as long as wind farms are built in places where winds often blow strongly, wind could be an important part of the energy mix.
