Hydrogen least pollution
Methane lowest carbon footprint of any fossil fuel
Nuclear no carbon and used more than any other
Probably natural gas.
oil
the answer to this is geothermal
Geothermal energy would be the renewable energy least dependent on the weather. Heat from underground is used to produce steam and generate electricity.
Natural gas (methane (CH4)) releases the least carbon when burnt of all the fossil fuels (coal, oil and natural gas).
At least 2000 years ago the Romans used hot springs for bathing and health. The hot springs were heated by underground heat, which is the meaning of geothermal.
are you dum?a circuit with a source of energy and at least one conductor is blah.
Yes they are, because they use non polluting wind power and provide energy that might otherwise require polluting sources of energy, such as coal, oil, or gas. The wind does not always blow enough to turn the blades, but, it does move enough to produce energy most of the time. Wind turbines do not pollute the wind, and they do minor damage to birds and bats. Nothing is perfect, and wind power is the energy that Probably does the least amount of damage to the environment, while providing an excellent source of energy most of the time.
The least expensive energy source causes too much pollution
coal
Geothermal
gasoline
bio-diesel
fossil fuels are the least costly for us to use.
no such thing. all energy sources produce at least some waste heat which can be considered a pollutant... even the cleanest. Perhaps one could say "order of magnitude of pollution".
oil
A conventional source of energy would be one that has been in use for quite a while - say, for a few decades at least, and on a sufficiently large scale. This is not the case with lightning.A conventional source of energy would be one that has been in use for quite a while - say, for a few decades at least, and on a sufficiently large scale.
