Sources do not contribute to needs, they contribute to SUPPLY.Needs are generated by people and industry.
Fossil Fuels
Fossil fuels
Burning fossil fuels (combustion) releases carbon dioxide. As carbon dioxide is a greenhouse gas, presently contributing to global warming, this is why the world is moving away from fossil fuels to renewable energy.
because we need fossil fuels for every thing tv iron and any electrical
we need energy
Even though Fossil fuels are bad for our world, they are important because there is no cheaper energy out there. It can be transported easiy as well.
the energy that is in fossil fuels is chemical and radiant energy.
No, unfortunately, it's the other way round. The use of energy sources from the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, releases carbon dioxide. This is one of the greenhouse gases that is contributing to global warming, not global cooling.
Any of the renewable energy sources can be used instead of fossil fuels (coal, oil and natural gas). They have the advantage of being clean, green and non-polluting to the environment, and not contributing to global warming. They are solar, wind, hydro, tidal and wave, and geothermal among others.
- no air pollution - no greenhouse effects - no fossil fuel - the most important alternative source of energy - it is the energy of the future
