Is biogas a non-fossil fuel natural gas?

Question

Hi, I'm doing a project on alternative fuels and when I searched wikipedia it listed "non-fossil fuel natural gas" as one. May I know what is a non-fossil fuel natural gas and is biogas included?

Answer 1

Bio-gas is diesel mixed with veggie oil.

Answer 2

Not always some people call bio gas a mixture of ethanol, and regular gas. Non  fossil fuel gas is just ethanol , and lees then 5% ffuel gas in some places, just ask where you buy is only way to find out.
