Britain is in the middle of serious energy crises! We 1______(look for) a new form of energy which will be able to generate enough power in recent years.

Usually the British 2_______(burn) fossil fuels or 3_______(build) nuclear power stations. As a result they emit harmful greenhouse gases, which4_______( cause) global warmingand climate change.

How can we produce enough energy without damaging the environment? What can we use as an alternative reliable form of energy? Wind power.

The countries like Holland and Denmark 5______ ( use) wind power as an alternative source of energy for many years. Britain is one of the windiest countries in Europe, but it 6_____ (be) slow to take advantage of wind power. The strong wind which 7_______ (blow) around Britain’s coastline could easily be used to provide us with all energy needs. All we need now is to set up some wind farms.

Wind farms 8______(be) a number of electricity generating wind turbines,which are tall, slim towers with two or three rotor blades at the top. The wind 9______(turn) the blades, which rotate the pole. Computers monitor the wind direction and speed, and can shut down the turbine if the wind 10_______(become ) too strong. We 11______ already (install) a single wind turbine which can produce enough electricity to power 375 homes, and it never 12______ (make) any noise.

So, wind power offers a solution to all our energy problems by being a renewable,clean and safe source of energy which easy to live and work with.
