Efficiency measures are things that get built into systems; conservation is behavior, and utilities see conservation behavior being strongly driven by the economy, and thus only temporary.)" and "... decreasing correlation between power demand and GDP."
- 2012/09/24: Ian Marchant, chief executive of Scottish and Southern Energy, says that CfD pricing should target something nearer onshore wind or gas (and nuclear generators should focus on cost control) not the figures touted in the press: "... we should have as our anchor price £75/MWh and, as a country, we should walk away at anything over £90/MWh, if not less," the difference being £70 per household per year.
- 2012/09/24: Heating controls often aren't used effectively: "Research indicates that households can save an average £59 per year on heating bills just by installing a room thermostat.

Old 'Saving Energy' News From Yesteryear
- 2012/11/05: Initial findings of Technology Strategy Board (TSB) Retrofit projects: eg, it is difficult to get thermal bridging, insulation and air-tightness 100% right, but 80%+ CO2 reductions are possible.
- 2012/10/18: University of Surrey Study Efficient Household Appliances: "The study found that in all cases appliance replacement yielded savings. By replacing a 5-10 year old fridge freezer with a fairly standard up-to-date (A or A+) model yielded savings between 40% and 60%. There were significant additional savings when consumers were asked to adjust their behaviour. When consumers switched to a lower temperature wash on washing machines it typically yielded energy savings of between 35% and 59%."
- 2012/05/12: YouGen's updated energy efficiency guide.
- 2012/04/02: New energy saving advice line launches: energy efficiency advisors will be on hand to take calls from the public on 0300 123 1234.
- 2011/04/29: 2,400 MW surge as television coverage passes back to studios as Kate and William reach Buckingham Palace. "This impact in demand was broadly in line with National Grid's forecast, although the final surge was larger than expected, reflecting the huge interest in the event. The 2,400 MW surge compares to the 1,800 MW surge seen during Charles and Diana's wedding, and the 750 MW surge seen during Edward and Sophie's ceremony."
- 2010/12/20: Carbon Compliance recommendations released: 10kgCO2e/m^2/y for detached houses to 14kgCO2e/m^2/y for low rise apartment blocks...
- 2007/09/23: the BBC reports that investors urge action on climate change, including analysis from Lehman Brothers economist John Llewellyn showing that cutting waste should come early in the process or reducing environmental impact.
- The Automomous House page claims that UK average household electricity consumption is 3MWh/year (presumably as of ~1994) from Boardman B et al (1995) "Executive summary" DECADE second year report Energy and Environment Programme, Environmental Change Unit, University of Oxford p2 (I see 4MWh+/year suggested elsewhere, eg BWEA ~4.7MWh/y, for circa 2006).
- Each geographical/supply area and season will have its own characteristic load curve demand peaks and troughs, for example in Mumbai/Bombay the two peaks seem to be 0900--1200 and 1800--2200 (local time), with heavy load management demand curbing being brought in in May 2005 to reduce wastage 1700--2300.
- Total UK electricity consumption is just short of 400TWh/year as of 2006/2007 (382.5TWh in 2006),
eg Energy White Paper 2007: "5.1.8 The UK currently has around 76GW (gigawatts) of electricity generation capacity to meet annual consumption of about 350TWh (terawatt hours) and
winter peak demand of about 63GW."
- Also see UK Energy in Brief: 2007.
- Alan Smart, energy operations manager for National Grid, is quoted 2007/09/06 by the BBC
Typical evening demand this week across England, Scotland and Wales will be in the regions of 41,000 MW.
If the Grid's analysts' predictions are more than 300MW out, the incident might be investigated, says the BBC.
The piece also discusses big "pick-ups" from various TV events, such as
20020621 England v Brazil World Cup 2570MW, which is a lot of sulky cups of tea!
- See the BWEA's UK Wind Energy Database (UKWED), as of October 2007 showing ~2.2GW of operational wind generation in the UK, ie maybe 5% of peak demand.
- As of November 2007 the BBC reports that "83% of respondents throughout the world agree that individuals will definitely or probably have to make lifestyle changes to reduce the amount of climate-changing gases they produce."
- One idea behind a global electricity grid or 'hypergrid' is to flatten out local peaks and troughs and have power 'follow the sun'. Many countries are already interconnected, and this global grid has the advantage of allowing injection of more RE/intermittent sources, eg solar PV in England could be powering the night lights of the far east of Russia 12 or 13 timezones away. A large interconnected grid eliminates at least some of the need to store lots of power from intermittent RE sources. Such a grid can be built regionally first, such as this European Supergrid.
- See maps of regional and national power grids and interconnections around the world.
- Power plants' CO2 levels revealed on the BBC News site, November 2007. "The UK's 192 million tonnes make it the ninth highest emitter, with per capita CO2 emissions of 3.2 tonnes." See the CARMA: Carbon Monitoring for Action site containing information on the carbon emissions of over 50,000 power plants and 4,000 power companies worldwide.
- It is considered good practice for electricity generation systems to have ~15% margin of supply over (peak) demand: at the start of 2008 Eskom of South Africa had as little as ~8% resulting in repeated load-shedding and blackouts.
- As of May 2007 the UK's significant generation plant stock included, by fuel: 68 gas, 18 coal, 10 nuclear. In 2007Q3, of the 13Mt of coal burnt for electricity generation ~10Mt was imported. Source BERR.
- The UK's National Grid published real-time stats on power usage and frequency with the graphs showing a very distinct daily and weekly cycle with a somewhat counter-intuitive daily shape with peak demand ~8pm and minimum ~4am. See strange Christmas 8-day graph up to mid-day 20071227 (and 2009) with each day looking more like a weekend than a normal day, and with a strangely reversed morning-vs-evening peak pattern on Christmas Day (Tuesday 25th), possibly from people coming down early to open presents and put on the Christmas tree lights? Also see the little extra surge around midnight on 20071231 (and 20091231 and 20101231) presumably for New Year's Eve events! See also some sample August 8-day and 1-day National Grid demand curves, and some analysis of typical GB seasonal demand/load curves. Also see Christmas workers: National Grid.
- "DUKES": Digest of UK Energy Statistics (and the 2008 PDF from which some headline figures are that renewables generate a little under 5% of UK electricity at ~20GWh/y up a little under 9% from the year before with onshore wind the biggest increase, overtaking hydro for the first time).
- The 2000MU-UK meter from Maplin.
- Check your electrical power consumption with tools such as the Kill-a-Watt meter.
- I am able to deploy my X-10 devices and Linux server to remotely disconnect unused items from the mains and/or run large loads off-peak and/or do some realistic burglar deterrence, providing that the X-10 controllers use much less power than the appliances that I am considering controlling (typically <2W for each X-10 controller).
- Something "grid-interactive" like SMA's Sunny Backup or Sunny Island systems can provide the benefits of on-grid (for safe export of excess) and off-grid (the lights, fridge, etc stay on if the grid goes down) PV systems. In particular, a heating system such as a gas combi and/or heat-pump could keep running whereas normally they'd stop in the absence of grid power, keeping the house warm.
- Try iMeasure or just in general Read Your Meter regularly to really understand your consumption: you can only manage what you measure.
