<human>: What are the different types of energy and what are the pros and cons of each?
<bot>: 
1. Energy can be classified into two main categories: kinetic (movement) energy, such as that found in a car engine; and potential (stored) energy, such as that found in a battery.
2. Kinetic energy is generally more efficient than potential energy due to its higher density and lower mass-specific energy content.
3. Potential energy sources include fossil fuels, nuclear power, solar, wind, geothermal, and hydropower.
4. Fossil fuels are the most common type of potential energy source, providing over 80% of global energy consumption.
5. Nuclear power plants produce large amounts of radioactive waste which must be safely stored for long periods of time.
6. Solar power requires significant land area, making it an inefficient option in some locations.
7. Wind turbines require large amounts of space and have limited efficiency when used alone.
8. Geothermal energy has high initial installation costs but low maintenance costs.
9. Hydropower is widely available and relatively inexpensive, but it can cause environmental damage if not properly managed.
