Question

What energy resource produces greenhouse gases when it is used?

Answer 1

Fossil fuels

Explanation:

If you have natural gas and burn it, you emit carbon dioxide. Although not 100% methane, natural gas can be accepted as methane.

`"CH"_4 + 2"O"_2 -> "CO"_2 + 2"H"_2"O"`

Other fuels (such as petroleum and fuel-oil):

`"Fuel (C, H, S, N, Pb, Hg, ash) " +`

`"Air (78% nitrogen gas + 21% oxygen gas) " ->`

`"Emissions (CO"_2, "H"_2"O", "CO", "NOx", "SOx", "Pb", "Hg", "particulates)" + "ash"`

If you burn wood, you emit `"CO"_2`, too.

If you get electricity from solar, it does not cause any emissions (with the exception of the system fabrication emissions and installation type emissions) during its operation.
