For the amount of energy produce, answer varies depend on size of installation. It can range from few kW in pico-hydro to thousand of MW in large hydropower system.
For ratio of hydropower use in electricity production, answer varies among country depending on the available resource. Base on year 2010, 16% of world's electricity is hydropower.

Hydroelectric dams use the kinetic energy of water to produce electrical energy What is the environmental drawback of building hydroelectric dams?
Dams disrupt a river's ecosystem.
What are two ways energy can be stored?
Electrical energy can be stored in batteries. Water energy can be stored behind dams.
What turns gravitational potential energy into electrical energy?
Dams convert the GPE of falling water into electrical energy via turbines.
What is the applications of gravitational potential energy into mechanical energy?
In dams, water is often allowed to fall down onto turbines; here, the mechanical energy is converted into electrical energy.
How is water energy bad?
Building of dams to harness water energy destroys habitat for many species, including endangered species.
Why is the electricity produced at the bottom of the dams?
because gravitatinal potential energy of water is used to rotate turbines.
What kind of energy is generated by large dams built or rivers?
Hydel Energy, which means Hydro- Electric energy, i.e., electricity produced with help of water.
How is hydro electricity connected to renewable energy?
Provided water was available in dams, hydro electricity can be produced indefinitely.
Why do Pakistan need dams?
Well ! Pakistan has been facing energy crises for the past 4 years. The electricity produced there does't fulfil the needs. So, they need to build more dams to create more electricity to meet the needs of the population.
Where is hydroelectric energy produced in the world?
Pretty much anywhere where there are decent sized rivers, a need for electricity, and enough money to build the dams.
Which form of energy is used to tap at dams?
Potential energy is used to tap at dams. The energy is stored due to the height of the dam.
Hydroelectric dams use the kinetic energy of water to produce electrical energy What is the environmental drawback of building hydroelectric dams?
Dams disrupt a river's ecosystem.
What are dams built to generate energy from water call?
hydroelectric dams
How do you get hydro energy?
you get it from dams
How power is produced?
It is produced by hydroelectric dams. In these dams, falling water (water in motion) is used to turn turbines which rotate the alternator - the machine that generates the electricity.
What is energy possessed by water in dams?
kinetic energy
How is light energy produced nowadays?
Light energy is produced by spinning turbines with steam in a power plant to turn a solenoid in a magnetic field to induce a current. The source of energy to turn water to steam is what makes a plant "green" or not. There are coal plants, natural gas plants, and nuclear plants. Some energy is also produced from hydroelectric dams, where rivers spin turbines instead.
