The true statement among the options provided is:
**Hydropower uses the kinetic energy of water to generate electricity.**
Here’s the evaluation of the other statements:
1. **Solar energy can only be used on Earth. It can't be used in space.** - This statement is false. Solar energy can be harnessed in space, and solar panels are used on satellites and other spacecraft to generate electricity.
2. **Wind is the most commonly used renewable energy source in the United States.** - This statement is false. While wind energy is a significant source of renewable energy in the U.S., as of now, hydropower still accounts for a larger share of renewable energy generation.
3. **Wind energy does not use a turbine or a generator to produce electricity.** - This statement is false. Wind energy is harnessed using wind turbines, which convert the kinetic energy of the wind into electricity through a generator.
So, the only true statement is about hydropower.
