Why should we find new sources of energy and not keep using coal?
Coal is expensive to use.
Coal is cheap.
Coal is dirty and causes a lot of pollution, so need to find something that is better for the environment.
Coal does not pollute the air so we should just keep using it.
What is the correct order for how wind generators work?
Wind blows, it goes into the transformer, then it turns a turbine, the turbine makes the generator work, then it travels to your house.
Wind blows, it turns a turbine, the turbine causes the generator to make electricity, electricity flows to the transformer where it is intensified, and then it travels through power lines to your house.
Wind blows the generator causes the turbine to make electricity, electricity and then it travels through power lines to your house.
