HELP! What are 6-8 advantages and disadvantages of using wind and geothermal energy?

Wind energy is generated from wind turbines which are structuyres with blades that get presented to wind. The energy in the wind moves the blades which turn an electric generator.

Goethermal uses the heat in the Earth to het water making stem whih is used to turn a steam turbine which turn an electric generator.

Electric generators convert mechanical energy to electrical energy by the motion of loops of wire passing through a magnetic field.

Advantages of both:
Renewable/large source of energy. Wind is created by weather and the molten core of the Earth is huge.

Clean. No fuel is burned during generation of electricity. The energy required to build the devices is small compared to the energy generated over the life of the device.

Safe. Unlike nuclear, there is no hazardous waste or risk of raditation leaking.

“Free” – We do not import the source of energy from other countries which lowers our dependence on foreign oil.

No impact to food production – unlike bio-fuels, wind and geothermal do not burden our agriculture production.

Disadvantages:
Wind is unreliable. Wind farms are built in windy areas to increase the production. Since it is dependent on the weather – there is no way for humans to control it.

Wind farms are considered ugly – a blight on the areas where they are built.

Wind farms harm migratory birds.

Cost – currently the cost is higher per kWh to produce wind energy and geothermal. However, as the price of oil continues to climb and the world’s oil reserves are depleted, it becomes more attaractive economically.

Location – Geothermal and wine must be located at the “source” of the energy. The energy must be converted to electricity for transmission. Since many cities rely on oil or gas fired generation plants in their locale, the geothermal and wind are more supplementary than primary sources for electricity (nuclear and hydro-dynamic suffer the same issue. Since oil can be transported by ship and/or truck, and natural gas pipelines are all over the nation, it is easier to locate the generation near the demand).
