What country are you based in? In mine (UK) one the biggest outgoing costs is energy, mainly heating. There are various government schemes to help people with recent bills and ways of reducing energy consumption.
I haven't checked the statistics but here in Portugal at least for me the biggest outgoing costs are rents (by a large margin), followed by food. Gas prices and car maintenance costs are also high, whereas public transport is roughly on a par with monthly energy costs.
Are people in the UK all heating their homes with electricity?
