overall household energy use and costs

It is important to get overall household energy use into perspective to understand where to cut costs and when to invest in new equipment.

The first pie chart shows the major components of energy use in the average UK house. Heating your home clearly dominates, followed by heating water. Electrical appliances and cooking are relatively low in energy use in your house (It should be noted that in reality when considering the inefficiencies of power generation that the actual energy use of electrical appliance is higher).

The second chart shows the relative costs assuming that Gas is used to cook, heat the house and heat the water. The cost contribution from electrical appliances is higher than the "in house" energy use; this is simply because electricity is much more expensive per kWh than gas.

The conclusions are apparent; to really save some money where you live the first focus should be on heating, hot water and insulating against heat loss. Much of the site focuses on the various heating and water options, and looks at insulation. The objective is to help to inform choice on what is best to do in your circumstances, to save money and sensibly invest.

Energy usage in a solid wall property - Glynn  2013-11-23 07:57:10
Would the % of usage and cost for space heating be greater in a solid wall property with twice as much heat loss as a cavity wall?

Hi Felix The charts I did myself in excel The data for the charts comes from "energy consumption in the UK" a DTI document. What is the department called now, Berr, BIS, it changes on a monthly basis and I can't find the docs anymore! I have a printout and should be able to find the PDF, if you send me your e-mail, I'll send it. Cheers Richard
