Although wind turbines for electricity generation bring a lot of positive impacts to our life and environment, they also bring some negative impacts. Every year thousands of birds, and bats are killed by the giant blades of the wind turbines. To minimize this negative impact, engineers need to study the migration routes of birds so that wind farm will not be built inside the routes. Wind farm occupies huge area of land and generates noisy sounds. As a solution, developed countries in Europe build wind farm at sea.
Today, most of our home appliances are powered by electricity. The number of electrical vehicles rises every year. If we use renewable energy, we can continue to supply electricity to our modern society and at the same time reduce our emission of CO2 gases.
Wind power, together with solar power, hydropower (from potential energy), Ocean Thermal Energy Conversion, sea tides/ current, and geothermal power can be used as renewable energy resources to support our life. - written by Charles Roring
