Why are solar energy and wind power considered renewable resources?

When we talk about renewable energy, we are talking about sources that can give a reasonable supply of energy for an almost indefinite amount of time. For instance, wind energy is not something that we can use up, same with solar. Resources like trees are also considered renewable, though that brings up an important point. There is a certain level of logging that we can do that is sustainable. However, if we exceed that level, we will run out of forests. Trees can only grow so fast.
Most renewable energy sources will draw their energy ultimately from the sun. Solar is an obvious one. Wind comes from cold and hot air masses (the hot ones being heated by the sun). Hydro power works because of the water cycle (driven by the sun) moves water to higher elevations, and we get energy from it as it comes back down.
Geothermal does not fit into this observation. Geothermal energy comes from deep within the earth, using the heat stored in the earth, not heat from the sun. Ideas for generating electricity from tidal actions would ultimately get energy from gravity and the rotation of the earth.
The point of all of this is that renewable energy comes from sources that will last so long that for us, they might as well be capable of lasting forever. Not only that, but our using them for energy is not going to shorten their life span. Whether or not we take advantage of energy from the sun, it is not going to burn out any earlier than it would otherwise.
Contrast this with crude oil. Although supplies are vast, they are finite, and rather small compared with other energy sources mentioned. Also, even though the supply of crude oil ultimately could be renewed, the time table for that to occur is so long, that for us, it might as well not be possible. It doesn't do us any good to wait a million years for more oil to form.

∙ 14y agoSolar, Geothermal and biomass are renewable energy because they are provided by nature and all we have to do is tap into them. Secondly these sources do not diminish on use.
Alternate or renewable energy seems to offer the solutions to the energy crisis of the future. They are also less damaging to the environment.

What is the 2 renewable energy resources?
Solar Power, and Wind energy.
10 renewable resources?
They include: Tidal Power, Wave Power, Solar Power, Wind Power, Hydroelectricity, Radiant Energy, Geothermal Power, Biomass, Compressed Natural Gas and Nuclear Power. There are many sources of energy that are renewable and considered to be environmentally friendly and harness natural processes.
What are France's nonrenewable and renewable resorce?
Some of France's Renewable resources are Nuclear Energy, Hydro-power energy and tidal power (Europe's biggest tidal power station) France's non-renewable resources are Coal/Peat, Oil and natural gas.
How can the energy from renewable resources be used to generate power?
Those resources can be converted into whatever type of power is needed.
What renewable energy resources are not in danger of running out?
All renewable energy resources are not in danger of running out. That's why they are renewable. They keep on coming and can be used over and over again. (Non-renewable energy resources are like coal, which can only be used once.) The sun is a renewable source of energy that is no danger of running out, not for billions of years. Wind and water power and the power of the tides, and geothermal energy from deep under the ground are also not in danger of running out.
What is a continuous resource?
If you mean a renewable resources then water power, wind power, and solar power are all considered to be renewable.
What are some renewable and nonorenewable resources?
Renewable resources are Wind, Solar Power, Geothermal Energy, Tidal Energy Nonrenewable resources are Oil, Natural Gas, Coal, Things like water and trees are renewable as long as they are properly conserved.
Renewable energy comes from natural resources that can be used up What are two kinds of renewable energy?
Your question is not correct. Renewable energy comes from natural resources that are NOT used up. That's why it is called renewable.Two kinds of renewable energy that can be captured to generate electricity are:solar powerwind power.
Why are nonrenewable energy resources used more frequently then renewable ones?
The power resources that have been in common use for a long time is termed as conventional power resources.
What is a difference between renewable resources and nonrenewable resources?
The difference between a renewable and a non-renewable resource is generally the timescale over which the resource replenishes. Something would be considered 'renewable' if it replenishes over the same timescale in which it is used. Technically, all our energy resources are theoretically renewable, but fossil fuels replenish at an astronomically slower rate than we use them (they basically represent a form of solar energy from millions of years ago). Solar power and wind are renewable. Hydropower is basically renewable. And geothermal power is considered renewable primarily because at the point at which it is used up, the earth will basically no longer exist as we know it anyway.
Give three more examples of renewable energy resources?
Renewable energy! Solar energy, wind power, hydro power and Geothermal power. Hope i helped:)
What is an example of renewable resources?
Wind and solar energy are examples of renewable resources. There is a (practically) inexhaustible supply of each. Geothermal energy is another, less exploitable source of energy.Hydroelectric power can be considered renewable in the short term, providing the water is not diverted to other locations. Tidal power is another constantly available form.Wood, since it is made from trees, can be grown and replenished, but cannot have wide usage to provide energy for modern societies.
