The Sun heats and evaporates water. Some of this water falls as rain and is collected behind dams. An amount of this water is released through passages in the dam and travels downhill and gains kinetic energy. The water then passes through a device such as a turbine which spins. Energy is extracted from this spinning and is used to make machines work, usually by generating electricity. Sometimes the energy is used directly as in a water wheel to run machines. So your answer is solar power, condensation to make rain, construction to build dams, engineering to develop turbines and water wheels, electrical engineering to transport electricity, and science to make everything work at the usage site.
What else can I help you with?
What type of energy does water behind a dam have?
Heat from the sun evaporates water. Uneven heating of the earth's surface causes wind to blow clouds up into the mountains. Rain falls on the mountains and makes its way down the mountain into streams which fill the lake behind a dam.
What the difference between ocean energy and hydro energy?
Ocean energy refers to various forms of renewable energy derived from the ocean, such as tidal, wave, and thermal energy. Hydro energy, on the other hand, specifically refers to energy generated from flowing water in rivers or dams. While both sources come from water, ocean energy harnesses the power of the ocean, while hydro energy focuses on rivers and dams.
What is the science behind the resource type of energy?
Energy resources can be classified into renewable and non-renewable categories based on availability and environmental impact. Renewable resources, like solar and wind energy, are naturally replenished, while non-renewable resources, such as fossil fuels, are finite and have associated environmental concerns. Understanding the science behind these distinctions involves studying the natural processes that generate and deplete these resources, as well as the technologies used to harness them for human use.
Is hydro energy made by flowing water?
Hydro-electric energy can be created in many ways, but all forms of energy require the spinning of a turbine to generate electricity.
Is hydro energy powerful?
No, hydro-power comes from moving water so it is kinetic energy.
Where do you store hydro energy?
Hydro energy is stored as potential energy in the water build up behind the dams. When it becomes electrical energy it is not stored but fed into the grid to supply householders and factories.
What is the science behind breaks?
The science behind BRAKES is that you use friction to convert kinetic (moving) energy into heat energy to stop a vehicle.
What type of energy is potentail energy?
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.
How much is hydro?
what is hydro energy
What is the source of hydro power energy a model for school?
Hydro energy is energy made by water.
Is rain going to be a renewable energy resource in France?
Rainfall captured behind a dam can be used by a hydro-electric power station to generate electricity. France has many hydro schemes running already.
Where does hydro power get its energy?
Hydro is Latin for water so hydro power gets its energy from water. It's often powered by a waterwheel.
Is Hydro Energy man made or natural?
Hydro energy is man made from natural resources
Is hydro energy and hydro power the same?
Basically, yes.
What is a hydro-electracity?
hydro-electricity is water power of energy
What is good about hydro energy and what's bad about hydro energy?
the good thing about hydro energy is that water (hydro) is all around us so we will pretty much never run out of it. the bad thing is it's hard to control
What is a Renewable types of energy?
Hydro energy
