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.
What else can I help you with?
What are four examples of Renewable Resorces?
Four examples of renewable resources are solar energy, wind energy, hydropower, and biomass. These resources can be replenished naturally and are considered environmentally friendly alternatives to non-renewable resources.
What are some renewable natural resources?
Some renewable natural resources include solar energy, wind energy, hydroelectric energy, biomass (such as wood), and geothermal energy. These resources can be replenished naturally and are considered more sustainable long-term alternatives to non-renewable resources.
Is power stations energy renewable?
No, power stations that use fossil fuels such as coal, oil, and natural gas are not considered renewable sources of energy because these resources are finite and can be depleted. Renewable energy sources, such as solar, wind, and hydropower, can be replenished naturally and are considered more sustainable in the long term.
What is the 2 renewable energy resources?
Solar Power, and Wind energy.
Which is not a renewable energy resources?
Coal is not a renewable energy resource. It is a fossil fuel that is finite and non-renewable, unlike solar, wind, and hydroelectric power which are sustainable and replenishable resources.
Is nuclear power a renewable energy resource?
No, nuclear power is not considered a renewable energy resource. It relies on the fission of uranium or plutonium, which are finite resources. Although nuclear power produces electricity without emitting greenhouse gases, its fuel source is not renewable.
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.
What all renewable resources are renewable . Do you agree?
Renewable resources include solar energy, wind energy, hydroelectric power, geothermal energy, and biomass. These resources are considered renewable because they can be replenished naturally over time and are not depleted when used sustainably. I agree that transitioning to these resources is essential for reducing our reliance on fossil fuels and mitigating climate change. However, the sustainability of some renewables, like biomass, can vary based on how they are managed.
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 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.
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.
