Wind Benefits: Natural, no energy is used or wasted, non polluting. Disadvantages: You need only wind and sometimes there is none so you will have no power when the wind isn't blowing.
Hydroelectric Benefits: Natural with water, won't pollute the air, each state can use its own energy with this source and not rely on other states or areas for power. Disadvantages: It is expensive, there will be droughts, and environmental consequences.
Biomass: benefits include that it is always available and can be produced as a renewable resource. Disadvantages: agricultural wastes will not be available if the basic crop is no longer grown,additional work is needed like harvesting plants.
Nuclear advantages: Reduces the amount of energy generated from fossil fuels,Less use of fossil fuels meaning lowering greenhouse gas. Disadvantages: Radioactive waste is extremely bad for the environment.
Solar: advantages it does not use energy just the natural energy which is the sun which is very good for the environment. Disadvantages is that if there is no sun that day or less sun you will be out of power for the day much like the wind you need a constant in order to have a constant energy source.
Other "coal" advantages is that it is abundant and not expensive. Disadvantages is that by burning it it releases harmful waste into the environment, and even acid rain in some regions.
