Renewable-vs-non renewable resources (types and uses)

Uses:


All these resources are being mainly used to generate electricity. Oil is also used for transport and the production of plastics.

Renewable Resources


A renewable resource is something that is being continually replaced faster than we use it up.
  • Solar energy is considered a renewable source of energy because no matter how it was done it still was done by a complet ediot
  • Wind Power
  • Water Power (Hydro-electricity from dammed rivers, tidal streams and ocean waves)
  • Thermal Power from the earth (Geothermal: Using the earth's heat to generate electricity)
  • Thermal Power from the ocean
  • Biomass, the burning of plant material, is a renewable resource. Even though the burning puts carbon dioxide into the atmosphere, it also prevents a much greater amount of methane being released by the decomposing vegetation, so it is rated as positive.

Non-Renewable Resources


A non-renewable resource is something that is not being replaced as we consume it.
  • Oil is a good example of a non-renewable resource. It is used to make gasoline and other fuels, as well as plastics, such as grocery bags. We are using billions of gallons of oil every year, but it takes millions of years to be replace. We are using up oil much much faster than it is being produced. Once we use up oil from the earth, it's gone. We can't wait millions of years for some more.
  • Coal is non-renewable.
  • Peat is non-renewable.
  • Uranium is non-renewable.
  • Trees are often considered a renewable resource, but that is only true in certain circumstances. If a forest is well managed, than the trees can grow back faster than we cut them down. However, in many parts of the world (including in the US), forests are being cut much much faster than they regrow, and this is therefore not considered renewable.

Most of the time the two terms are referring to sources of energy:
Renewable sources are sources of energy that can be reused or that will continue regardless of you using them: power from the Sun, power from waves, power from wind.
Nonrenewable sources are sources of energy that have a limited supply and will run out, and not be able to be used in the future: Oil, Coal, Northsea gas.

A:


Well, renewable energy sources are wind and hydro. They will never run out. Nonrenewable energy sources are coal. Nonrenewable energy sources are fossil fuels. The similarities are that most of them have a relation with the sun. A nonrenewable energy source and a renewable energy source are similar in the way some of them are used to transform energy (you cannot create energy, it can only be transformed from one energy to another.) The similarities are few but there are many differences, most of the positives are on the renewable energy's side.

A:


Renewable resources are structures that will never be in shortage but non-renewable resources are structures that can be in shortage and takes years to recover

A:

CHARA(:
Uranium is nonrenewable.

A:

Non-Renewable


When you use petrol, gas, coal... basically anything you burn to produce heat and then turn this energy into electricity of mechanical energy (a car engine) you are using a raw material that is not going to be replaced. In fact petrol, gas and coal takes million of years to be naturally produced.

When you are burning wood (from trees), the tree grows again... eventually if you let it do so. This energy can be "kind of renewable" as long as another tree grows as fast in order to replace the one you cut.

CHARA


Minerals like, iron ore and gold are nonrenewable, as are oil, coal, and other fossil fuels.
