If you wish to minimise electrical energy usage in the home then every few years I suggest take the trouble to look at the energy your electrical appliances are using. In particular freezers and fridges. With the increase in local shops and the increasing household habit to shop local then there is less of a need for large fridges and freezers. Some of the older freezers use a considerable amount of energy that does not justify use considering the relative small savings available for bulk buying. This is particularly so if the number of occupants in the house has reduced for example if teenagers are growing up and leaving home. Simply swapping out of a large old chest freezer and a old fridge could make a dramatic difference to energy use, enough to instead pay for a new compact fridge freezer over say 8 years.
Other high energy use appliances include washing machines and dishwashers. When you need a new one then choose a washing machine that has a decent range of cool and cold wash programmes because heating cold water up by electricity is relatively expensive. Unfortunately the choice of hot water fill washing machines is now fairly limited which was useful if water is heated by gas, wood or solar energy. But cool or cold wash with bio type detergents is I think satisfactory for most items, though not tried it myself it is possibly OK for everything.
Hopefully most homes have now got rid of filament lamps (bulbs) for lighting in lights that are used frequently and have newer low energy type lamps. Compact Fluorescents have been around for many years and are cheap, LED bulbs are readily available. I would expect to see filament lamps only in rarely used places such as store cupboards and maybe a cloakroom, but even then I cannot see a reason for continuing to use them because LEDs produce instant light are not expensive.
Oh and finally is you have a house with vast numbers of those silly 40 watt GU22 halogen downlighters lamps that don’t last long anyway and are fiddle to change. Then get an electrician in to swap them all out for good quality GU22 LED lamps instead. The electrician would at the same time be able to check from a safety perspective as to whether the correct type of downlighters are installed in higher risk areas such as bathrooms.
