What energy resource produces greenhouse gases when it is used?

Answer 1

Fossil fuels

Natural gas can be accepted as methane even though it isn't 100% methane when burned. Burning natural gas releases carbon dioxide.

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

Additional fuels (like fuel-oil and petroleum):

#"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.

With the exception of emissions related to system fabrication and installation, solar electricity does not emit any emissions while it is in use.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
