Answer: See below
Explanation:
Solar energy: Advantages: Solar energy is pollution free and causes no greenhouse gases to be emitted after installation. Disadvantages: Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.
Wind energy: Advantages: It doesn't pollute air like power plant relying on combustion of fossil fuel. Disadvantages: Wind turbines can be a threat to wildlife (e.g. birds, bats).
Hydroelectric energy: Advantages: Hydroelectric energy is fueled by water, so it's a clean fuel source, meaning it won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. Disadvantages: Electricity generation and energy prices are directly related to how much water is available. A drought could potentially affect this.
