Because for them to replenish takes millions of year.
Hydrogen is not a fossil fuel because it is renewable. Sources of energy that are non-renewable are considered fossil fuels
- Fossil fuel energy sources (coal-natural gas - petroleum - wood) - Nuclear energy sources (fission - fusion). Nuclear energy may be considered as renewable energy source.
Renewable energy cannot, at present, replace fossil fuels or our use of them.
yes, fossil fuel is another name for non-renewable energy sources.
Non-renewable sources of energy - fossil fuels (coal, oil and natural gas).
Because if we use renewable sources, it's with us forever. fossil fuels and non-renewable sources will run out someday.
Energy from the burning of fossil fuels (coal, oil and natural gas) is non-renewable.
Coal oil and natural gas are non-renewable energy sources in that they take millions of years to form in Nature. They are all called Fossil fuels.
Fossil fuels are non-renewable so have a finite supply. This means that they will eventually run out. They also produce carbon dioxide when burnt which contributes towards global warming. Renewable sources do not pollute the atmosphere and do not run out. Therefore renewable sources are better for the environment, but fossil fuels give more energy per mass. Which is better depends on what you look for, environment and sustainability or high density of energy. Renewable energy still gives out sufficient energy, so renewable sources are better.
Renewable energy sources:Wind power is a renewable energy source.Solar power is another.Fossil fuels: Coal is one of the fossil fuels (coal, oil and natural gas).Oil is another.
Fossil fuels (coal, oil and natural gas).
It depends where it comes from. Energy from solar, wind, water etc is renewable. Energy from burning fossil fuel is non-renewable.
