Electricity.
Hydro energy
Hydro power has potential gravitational energy. Gravity will move the water. Moving water has kinetic energy.It is also renewable energy.
Renewable energy is the type of energy that can be replenished naturally in a relatively short amount of time, such as solar, wind, hydro, and biomass energy.
Energy can not be created or destroyed. Therefore, to "generate energy" you need some other kind of energy - you convert one type of energy into another.
Hydro - Electric
Hydro-electric
Power plants generate electrical energy. This energy is typically generated by converting other forms of energy, such as mechanical energy from turbines powered by steam, gas, or water.
Potential energy is the state of matter in which it is not at rest, or at its lowest state. A charged battery has potential energy, as does the water behind an hydro dam.
You don't have to worry about hydro energy depleting because this type of energy comes water being turned into energy and everything we use goes back into the air as water vapor and that will go back into the water cycle. that's why the hoover dam uses hydro electric energy because it is a reusable resource.
Nuclear energy is a type of energy that needs very little mass. Nuclear energy is used to generate electricity and heat.
There are solar power, hydro power, geothermal power, nuclear power, gasohol, and biomass
