What temperature is your house right now?
How much electricity do you use?
What's your gas bill?
Even if you assume that any some of the responses are true, what possible difference can it make knowing the answer?
Salary - depends on your job/how many hours you work.
Temperature - depends on the type of house/type of heating/whether you turn your heating on. Whether it's cold outside.
Electricity - electric heating/HW? Tumble drier on all day. Reduced tariff? Standard MN 47 thousand loads of washing an hour?
Gas bill - gas CH/gas cooker? Are you home all day/do you have small children?
My salary is zero.
House is currently 16 degrees but I have been out all morning so heating on low. It's minus 5 outside.
No idea how much electricity we use.
Gas bill - don't have one. We have a gas tank to supply the heating. Last filled up in February, will need refilling after Christmas.
My answers above may or may not be true. Either way, how does it move the conversation forward?
