Advantages and Disadvantages

Advantages:


They don't use non-renewable resources.

They don't pollute the air with carbon dioxide.

They don't leave radioactive waste.

Land around windmills can still be used for other purposes (like agriculture.)

Windmills can make electricity for individual buildings. In a natural disaster, these buildings would be self-reliant.



Disadvantages:

Some birds have been killed by wind turbines.

Wind mills are expensive to build.

They take up a lot of space.

It costs more money in the short term for the electricity than for electricity created by fossil fuels.

Turbines can be damaged in thunderstorms.

Some turbines produce noise that bothers neighbors.

The electricity produced by windmills can't be stored.

Some people think they are ugly and don't want to live nearby.
