The first way is to follow the rules that our grandmothers, parents and etc... have always told us. Turn off the lights and T.V. when you leave the room. This should also include turning off appliances when not in use, unplugging charges when not using and anything else that we may keep on stand by mode.
Winter time is also the time of year where I do a lot of baking and cooking. We often have guest in as the outside is not a good place to be and yet we all still love to be together. So when making those meals be efficient when cooking. One rule is that a watched pot does not boil and this is true about cooking in the oven as well. If you continue to open the oven door the heat bill will rise and the food will not cook properly. If possible lower the temperature of the oven and cook in batches to make the most use of the oven space.
Did you know that you only need to turn your heating thermostat down by one degree to save up to 10% of your energy bill?? The warmth of the room will not even suffer but you will save.
Hopefully these tips will help you save some green during the hottest or coldest times of the year
