# What energy resource produces greenhouse gases when it is used?

Aug 31, 2016

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.

$\text{CH"_4 + 2"O"_2 -> "CO"_2 + 2"H"_2"O}$

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

$\text{Fuel (C, H, S, N, Pb, Hg, ash) } +$

$\text{Air (78% nitrogen gas + 21% oxygen gas) } \to$

$\text{Emissions (CO"_2, "H"_2"O", "CO", "NOx", "SOx", "Pb", "Hg", "particulates)" + "ash}$

If you burn wood, you emit ${\text{CO}}_{2}$, 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.
