- Hydroelectric
- Water, typically from a dam/reservoir, is used to turn a turbine-generator to make electricity.
- But, a country must have rivers and the financial resources to build dams.
- Most rivers in the US that are suitable for dams already have them, and many large rivers cannot be dammed, as they are used for shipping.
- Wind
- Wind turbines with generators can produce electricity
- There are not emissions.
- But, again, these won't work everywhere, and they are expensive (but getting cheaper).
