What is the difference between renewable and non-renewable energy sources?
3 Answers | add yours
Renewable energy sources are ones which don't run out - which can be renewed. We can keep using them and using them, and we'll never run out. Examples of renewable sources include wind, water power (hydroelectric), and solar power (light from the sun).
Non-renewable energy sources are ones which do run out. As we use them to generate energy, they get used up, and can't be used a second time. There are three main non-renewable energy sources, which are fast running out: coal, oil and natural gas.
Hope this helps!

Renewable energy sources include solar, wind, geothermal energy. The simple meaning of renewable energy is energy derived from natural sources. We have unlimited supply of these sources and we can generate energy from them. They do not produce green house gasses that harm our planet. That’s why renewable energy is called “clean energy”.
Non renewable energy sources include coal, oil and natural gas. We have limited supply of these sources and we are running out of them. They produce gas emissions that harm our planet.

Basically, humans use lots of energy for heating, lighting, movement, machines, etc etc. That energy has to come from an energy source. Some sources are renewable, some sources are non-renenwable.
Generally speaking, Non-renewable sources are fossil fuels. These come from underground and are Coal, Oil and Gas. There is a fixed amouint of coal oil and gas in the world and when we have used it all, there is no more. We cannot 're-new' them.
Renewable sources are energy sources that will not run out. They can be used 'forever'. They include Solar Energy; Wind Energy; Wave Energy; Geothermal energy.
Fossil Fuel cause lots of pollution. Renewable energy sources don't cause pollution.
