Wind Turbines.
This involves putting lots of wind turbines in exposed places like on moors or round coasts.
Each turbine has its own generator inside it, so the electricity is generated directly from the wind turning the blades, which turn the generator.

advantages:

The only pollution that is created is in the manufacturing process.
Renewable.

No fuel costs and minimal running costs.

No permanent damage to the landscape - if you remove the turbines, the view returns to normal.

disadvantages:

It's unreliable - if it isn't windy, there is no power.

They spoil the view - You need around 1500 wind turbines to replace one coal-fired power station. This number covers a lot of ground, making a big effect on the scenery.
They can be very noisy, which is annoying for people living nearby.
The initial costs are high.
It's impossible to increase supply when there is extra demand.
