Explanation:
Gravity plays a very important role in the production of electrical energy in a dam.
The water used in a hydroelectric power plant is driven under the pull of gravity.
Energy conversion which leads to the production of electricity is from potential energy more specifically, gravitational potential energy to kinetic energy of the electricity.
Potential energy is the energy due to the position of a body.
Water in a dam, is passed through a channel in dam. The channel is held high up, as the water falls through the channel, it impacts and drives a turbine along its path.
This in turn is connected to a generator that produces electricity.
Gravity increases with the mass of the water and causes the gravitational potential energy of the water to drive the turbines.

These currents are on the oceans surface and in its depths, flowing both locally and globally.
Many nations use oceans to drill for oil which is a non-renewable resource that often damages the ocean and can cause major problems for the biome. This means also that more oil is used then so that's bad for the environment too. Sometimes there is an oil spill which kills many animals and plants that live in the ocean and cause a natural disaster. Even renewable resources from oceans like using water and dams to make electricity can be problematic because the water gets polluted. It would be best if countries switched to things like solar energy and wind energy.
