My highest priority once I bought my house was to go as energy efficient as possible.
We bought all new appliances, and all of them were energy efficient (that could be at least, ovens can't be).
Our utilities usually aren't terrible, winter is $220 a month for electric and gas, summer is $150. Water is $100 every other month. Garbage is $100 every 3 months.
We need new windows so we can save a little more heat, but our biggest issue is usually the electric side of the bill. With two young kids, it's hard to keep that shit down.
Yeah the problem is that when renting the old building never really have good windows so trying to keep utilities down in that regard is tough.
Lucky I don't have to worry about it now but my next place I may not get that lucky, unless I wind up in one place. Guess I should figure stuff out soon
