Reina was an architect tasked with designing an environmentally friendly hotel. The building would use a renewable source of energy, so she researched Wind Power. From her research, what is the negative effect of using wind energy on wildlife?
Wind energy can only be collected when wind is present.
In 2020, wind farms with many wind-collecting turbines killed 325,000 birds.
Wind power is clean and does not directly create pollution.
Wind gathering sites are usually located far from places that need the electric power 좋다
