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.
Wind mills, Solar cells or Turbines in the sea take their energy from wind, solar heat, and the attraction from the moon on the sea. There are based on "natural" energy. This energy will be available as long as our planet exists.
There are a couple of sites explaining how to build home made wind mills reusing common old materials... not very efficient but cheap and allows recycling... that is "using again something that is non renewable for another purpose".
Yes. depending on the rate of which deforestation happens and how quickly the trees will regrow effect wether it is classified as renewable or nonrenewable.
Areas of commercial forests are felled in rotation for timber, and new saplings planted for future felling. Therefore, timber is a renewable resource.
Biomass is a renwable resouce
It depends where it comes from. Energy from solar, wind, water etc is renewable. Energy from burning fossil fuel is non-renewable.

Yes, nonrenewable and renewable sources are different - very different. For example, nonrenewable sources such as fossil fuels harm the environment and will run out soon. Green renewable sources are good for the environment such as solar energy. It comes from the sun. That is why it is called solar energy.
geothermal energy is a renewable energy source: similar to wind, solar, etc.
some energy sources are non renewable but some are renewable
Because renewable sources can be replenished (apex) because we will not run out of them
All renewable energy sources are continuously renewed from energy from the sun, but of course ultimately the sun is nonrenewable.
it aint6 a such thing as school
The sources of energy are divided into renewable, nonrenewable, primary, and secondary. Most energy comes from nonrenewable sources that include oil, coal, hydrogen, natural gas, electricity, and uranium or nuclear.
is gravitatinal potential energy renewable or nonrenewable
Nonrenewable are energy sources that cannot be replaced once they are all used up. Renewable energy sources can be replaced. E.G The ice in your fried is renewable. Every time you take away the ice, new ice will form and fill it up again
For a while, yes. Long term, no. It is a non-renewable resource, and so we have to switch over to alternative energy sources.
is gravitatinal potential energy renewable or nonrenewable
It depends where it comes from. Energy from solar, wind, water etc is renewable. Energy from burning fossil fuel is non-renewable.
no but it can reform over billions of years. just stick to nonrenewable.
they are less expensive They can be used again
