Grammy nominated (格莱美奖提名)artist and globally admired DJ and Producer Paul van Dyk continues to lead the electronic music charts and appears at the highpoint of every Top DJ list across the globe. PvD, as his fans have nicknamed him, is currently ranked the World’s No. 1 DJ by DJ Magazine’s “Top 100 DJs poll” for the second successive year.

PvD is well-known as one of the hardest working artists, with sold-out tours that cross each continent, headline spots at every major festival, and a hugely successful recording career. With over 3 million albums sold worldwide, van Dyk travels around the world over 16 times each year to sold out performances internationally.

Born in Eisenhuettenstadt, East Germany, Paul van Dyk grew up in East Berlin. Because his community did not have a true club culture, Paul van Dyk listened to the radio where he discovered his passion for music that extended beyond Techno music-he wanted to create a different, more unique sound. In the early 1990’s Paul van Dyk was performing regularly at various clubs in Berlin before releasing his first album 45 RPM in 1994. But it was the release of his second album Seven Ways that put him into Top 100, followed by the release of his hit single “For An Angel,” which began to earn him praise across the globe. By the time Paul van Dyk released Out There & Back in 2000, it became clear that the Berlin-based musician had far more to offer than his signature club sets that had already defined him as one of the most influential DJs and producers of all time. His first mix CD Politics of Dancing was released in 2001, followed by Global in 2003-a DVD which illustrates his own experiences traveling the world.

We've used the wind as an energy source for a long time. The Babylonians and Chinese were using wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that. Wind power was used in the Middle Ages, in Europe, to grind(磨碎) corn, which is where the term "windmill" comes from.

We can use the energy in the wind by building a tall tower, with a large propellor on the top. The wind blows the propellor round, which turns a generator to produce electricity.   We tend to build many of these towers together, to make a "wind farm" and produce more electricity. The more towers, the more wind, and the larger the propellors, the more electricity we can make. It's only worth building wind farms in places that have strong, steady winds, although boats and caravans(大篷车)increasingly have small wind generators to help keep their batteries charged.

The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains-places where the wind is strong and reliable. Some are offshore. To be worthwhile, you need an average wind speed of around 25 km/h. Most wind farms in the UK are in Cornwall or Wales. Isolated places such as farms may have their own wind generators. In California, several “wind farms” supply electricity to homes around Los Angeles.

The propellors are large, to obtain energy from the largest possible volume of air. The blades can be angled to cope with varying wind speeds. Some designs use vertical turbines(垂直涡轮机), which don't need to be turned to face the wind. The towers are tall, to get the propellors as high as possible, up to where the wind is stronger. This means that the land beneath can still be used for farming.
