It's not always easy to separate the energy used to heat your home from that used to power lights and appliances, heat water, and charge electronics. For example, there are two different electricity rates (or tiers) charged by your utility. After consuming a certain amount of energy each month, you start being charged at a higher rate. Both B.C. Hydro and FortisBC also charge a fixed amount on each bill, in addition to charging for the energy you consume. You can see how it might be difficult to understand the costs and benefits of different heating options.
