Windmills that generate electricity are being
built in coastal areas. The main benefit of these
windmills is that they
(1) produce finite resources
(2) reduce dependency on fuels that cause air
pollution
(3) absorb the noise of passing boats
(4) maintain the salt concentration in the ocean
As they are built in costal areas,they use eolic energy to function ,which is a clean form of energy and thus reduces dependency on fuels causing air pollution
