Here is a guide on how to reduce carbon footprint.
You should, first of all, consider the source of your electricity bill. If you get electricity from the utility company, you will have to change that. But, if you take your electricity from the solar panel, then the whole concept of reducing carbon footprint would not need any alteration. It will also help you get rid of your electrical bills in the long run as well.
The second thing that you can do to reduce your carbon footprint is by using less of your energy consumption. It does not mean you need to completely cut down your expenses, but a little adjustment will be needed. If you live alone and have no partner, then it is a good idea to cook your food from the stove rather than the microwave oven. This way, you would be able to do more cooking at the same time and reduce your carbon footprint.
