Why are energy sources such as wind water and the sun considered renewable?

Because the sun will keep shining for so long that we really don't have to worry about when it will go out. And wind comes from weather, which comes from the rotation of the earth, and the warmth from the sun. Those won't run out anytime soon either.
And water,well, the biggest force that moves water around is evaporation - powered by the Sun - and then condensation - a basic characteristic of water, and gravity. They'll keep working quite long as well.

Is geothermal a renewable nonrenewable or inexhaustible source?
Geothermal is considered a renewable resource as it uses water and the earth's heat. Both of these are inexhaustible. However, if the water near the plant is exhausted (no more water in that area, but there is no less water than before), then the plant must be moved. It is still generally considered a renewable source of energy.
What is hydro Wind and solar?
Basically the words Hydro, Wind, Solar Refer to three different sources of Renewable Energy which produce energy from different sources like Water, Air, Sun's heat
How is hydroelectric power bad?
Its not neccessarily a bad thing, but its not a good thing either. Using water for energy can ruin habitats by flooding and not letting water flow naturally. Its better than some sources of energy because it dreates no pollution, and water is a renewable resource. There are lots of arguments debating whether or not it's the best choice. What about you. Choose your argument, what side are you on?
Moving water in a river is considered a renewable resource because it?
...because the river will keep running as long as the rain keeps falling in the catchment area above it.Climate changes may bring drought to some rivers, meaning there will not be enough water in the river for it to be a renewable resource any more.Because the energy moving the water up to form the rain which becomes the river water comes from the Sun. As long as the Sun heats the Earth, rivers will flow and energy can be taken out of the flowing water (eg to turn a mill wheel).
Is solar cell renewable?
Yes.Completely. No matter how much of the sun's energy we use, the sun will continue to shine just as much as it did before!Solar energy is renewable because, the sun's rays will never run out. That makes it renewable. Renewable energy sources will never run out and we will have a constant supply of them. And with renewable energy sources, we are not hurting the environment as much as when we use fossil fuels. See the link below.Once the sun burns out we will just "renew it" and get another one? Just like oil reserves the sun is a finite amount of energy.Not really, consider the question intelligently and ignore the public hype. A renewable resource at minimum should output more energy than is put into it. It should also not create a significant waste issue. Having worked as an engineer at the largest solar manufacturer on the planet, I can assure you that more energy is required to generate solar cells/pannels than it provides in its lifetime (~20-25 years). The materials used to generate the cells are also considerable and fill landfills. Some of the materials are hazardous and dangerous for the environment. Don't accept answers without substance. I believe in helping the environment but this is not the answer.
Is electrical energy renewable or non renewable?
The most popular renewable energy sources currently are: Solar energy. Wind energy. Hydro energy. Tidal energy. Geothermal energy. Biomass energy.
What are energy sources like sun and water?
The sun is a renewable source of energy. Water is not a renewable source of energy. It is a renewable resource as long as the rain keeps on falling on the same place.
Is there any other energy sources that are renewable?
Sunlight and water are 2 examples of renewable sources because they will never run out.
What what of the five renewable energy sources are actually indirect forms of solar energy?
water
What renewable energy sources do not need water?
wind powersolar power
Are non-renewable energy sources the most harmful to the planet?
They are because they polute the air and water of the earth.
Is energy resource or nonrenewable?
It depends where it comes from. Energy from solar, wind, water etc is renewable. Energy from burning fossil fuel is non-renewable.
What types of energy generation are considered renewable?
Hydro(water),wind generators andsolar powertidalwavegeothermalbiofuelare all considered renewable.
Fuels such as the wind and sun that can generate power without being used up?
Wind energy and solar energy are called renewable energy sources. Other renewable energy sources include hydroelectricity (generated by water movement) and geothermal energy.
Are atoms renewable energy sources?
Yes. Hydrogen is. ( if it comes from water) NO Uranium is nor
Are clouds a renewable source of energy?
No, clouds are not a source of energy. They are just puffs of water vapor floating in the sky. Wind and water are sources of energy.
How many sources of energy is not renewable?
Sources of energy which are not renewable are those that use up a substance to create the energy. These include fossil fuel energy (oil, gas and coal) and atomic energy (uranium and thorium).Sources of energy which are renewable are resources such as wood or other plant derived fuels. Generally included in this heading are those energy sources which are inexhaustible such as water power in its many forms, solar power, geothermal energy, and wind energy.
