In a speech this week to the Institute of Civil Engineering, the Prime Minister, David Cameron, made clear his support for wind energy. He focused on some of the many advantages of developing the industry.

Let’s examine those reasons. It is an abundant, clean and sustainable source of energy, reducing our dependence on expensive fossil fuel imports, increasingly from politically unstable parts of the globe. Let’s not forget that Russia turned off the gas supply to Europe in 2006.

More recently, we have all felt the pain this winter, when international gas prices soared by 40% compared to last year. Should we carry on exposing ourselves to the instability（不稳定） of global energy prices and the unpredictability of global events, or should we recognize the value of taking control of our energy supply?

As for the economic opportunities, over the last decade wind energy has attracted $5 billion in investment(投资) to the UK and is set to go above $50 billion by 2020. Look at the companies queuing up to build wind turbine (涡轮) factories in the UK, such as Siemens and Vestas. Examine the number of people employed in the wind industry in the UK—nearly 12000, now with nearly 90000 jobs by 2021.

The UK is already the global leader in wind power, with greater ability than anywhere else in the world—enough to supply more than a million homes with electricity all year round—and the government is calling for an increase by eight times in the amount of wind turbines installed by 2020, which the industry can achieve as long as it gets the right level of support from ministers. In return, as well as bring the environmental benefits of clean energy, the wind industry is committed to save consumers a lot of money.
