Answer :
A renewable energy source is a natural resource on Earth that can be naturally replenished in a short period of time. Wind is considered clean and renewable because it will not produce harmful pollutants or emissions and won't harm our ecosystem!
Wind is a clean energy source because the process of collecting energy from wind produces no by-products. It's a renewable source because even if we could remove ALL of the energy from a windstream ... which we can't ... the sun is always creating more of it.
