i recently bought a house and have concerns about energy costs this upcoming winter. i used to live in an apartment where i never had to turn on the heat because everyone elses heat warmed my apartment. so, now i have to figure out how to heat my own home and avoid the 250 buck plus gas bills that i see some of my friends have. what are some of the best ways to limit my energy costs? i have gas heating, a gas water heater and a gas stove. is it better to convert my gas energy appliances to electric?
