Setting my targets
"... for all of us, if we are going to make changes in our energy, we need targets. What are yours?"
My flat's electricity consumption was 2,475kWh/year over four years (2003-07), but measuring it over the last four weeks, it's down 33% to 1,650kWh/year. However, that's with just me in residence. A mixture of low energy lightbulbs, not leaving things on standby, not overfilling the kettle and so on. But you could also say that, by not having a lodger the usage per person has actually gone up!
This is actually a big issue. The percentage of one person households in Scotland has been rising steadily ...
- 1981 22%
- 1991 29%
- 2001 33%
- 2006 34%

Looking to the future, according to the latest Household Projections for Scotland issued by the General Register Office for Scotland, the government thinks this will continue to rise:
Between 2004 and 2024, the number of households consisting of just one adult will increase from 770,000 to over a million – making up over 40 per cent of all households in Scotland. The total number of households is projected to increase by 13 per cent to 2.5 million - an average of 14,800 additional households per year.
Meanwhile, my gas consumption has gone down year by year, which perhaps reflects different tenants ...
* 2003-05 Natasha 13,749kWh/year
* 2005-07 Jacqueline and Liana 13,067kWh/year
* 2007-09 Jacqueline and Sarah ... and Neil 11,988kWh/year
But that's still only a 13% decrease. Where do I start with a target? Firstly, get a lodger so I can divide my household usage by two! Beyond that, should I replace the boiler with a more efficient one even although there will not be a commercially attractive payback? How much energy does the new boiler cost to make?
But initially the key step is monitoring - knowing where it goes - so as to pick up the easy steps first. For example, there is a lot of rubbish talked about devices using energy while on standby. Some do - others use nothing. I plan to use my power meter to see just where the electricity is going, and to upgrade some of my building insulation (although there is a limit as to what you can do with my 1903 building.
I've also suggested that my church considers a 10% year-on-year reduction. Would we be prepared to commit ourselves as a holistic community to three steps:
- reducing the CCE energy usage (kWh/year - ) by 10% over the previous year (2008 = base year), each year for the next ten years. Thus by 2018 it will be 35% of 2008 level. Perhaps we could omit electricity from renewable sources under certain circumstances.
- a target of 70 CCE households signing up to reduce their domestic energy usage by 10% over the previous year, with the option to sign up for transport too.
- provide signposts to sources of support for those who sign up, including organising basic seminars and services on auditing your usage and preparing an action plan.
