I've tracked our electric usage over 12 years and on average its 4332 units p.a. We've always been energy conscious and until the beginning of this year thought there wasn't much more we could do without affecting quality of life.
However, with the horrendous price hikes - unjustiified in my opinion - we thought again and have made some more changes. This year so far we've consumed 2860 units and if the remaining 7 weeks are at the same rate as present then we should just go over the 3000 mark.
We've been more conscious of using the ovens more efficiently - so we plan bread and cake making etc. around the times when dinner was something that also needed to go in the oven. Earlier this year we bought a microwave - our first ever - and use it for the occassional heating which would have meant putting the ovens on, which spend a considerable amount of time and energy just getting up to temperature.
Hot water - electrically heated - is provided by two tanks. A small one and a large one. Both are independent and only switched on when needed. The large tank has a manual timer on it which you can set for 30mins, 1hr or 2 hours. We check the water temperature and turn on for the appropriate amount of time. This is used for showers etc. The small one is for sinks and switched on as needed and is located near them.
If you have a large immersion heater which needs to supply hot water to an outlet a long way from it then more cold water than you get hot at the outlet enters the tank which then requires additional heating.
The hot water solar panel supplies the large tank and we'll time having showers etc when its producing 'free' hot water. Ok - you don't have to stand upwind of us when the sun doesn't shine
. It's very noticeable that the electricity usage drops when the sun shines. Even in winter the panel may raise the temperature of the water a couple of degrees occassionally.
Washing machine and dishwasher are cold feed. The dishwasher gets put on for a full wash only when its - well full! Other times its a quick rinse.
We don't have a tumble dryer but the ventilation system provides adequate drying due to the dehumidification process. The vent system used to run 24/7 except during the summer when windows were open and it got switched off. Now we've extended the switch off period as there are still times in the autumn and winter when doors and windows get opened as we go in and out. We do make sure its on fully overnight though. During times when we are away it has an Unoccupied setting which just cycles it on/off in a 15/45mins ratio. Not quite the same as being fully off.
To aid the washing drying in the times when we can't put it outside - and this might seem a bit over the top - after the oven has been used in the evening we'll move the clothes airer in front of it with the door open. As we heat the house from a log burning stove we'll move the clother airer in front of that before we go to bed.
When at home we used to play music via the media center, which is a small computer and TV. The TV displayed a slide show of family pictures as random music plays. These days we're more likely to listen to the radio which uses less power than the media centre. The media centre gets switched on in the evening to watch something recorded or streamed. Its always powered off when not in use - not in standby.
Computers etc are always powered off after use and not left in standby. The only things on standby are the phones and router.
As previously mentioned we thought we couldn't save any more energy but we have. Can we do this again - doubtful!
