A while ago I promised a blog on the recent release of the UK energy data.\u00a0 This blog covers some of it.\u00a0 The energy data I’ve obtained is really very comprehensive and goes back to 1970.\u00a0 It covers almost very aspect of domestic energy use and patterns in the UK.\u00a0 Whilst this data is UK centric the broad trends are probably the same in most Western countries.<\/p>\n

Looking first at heat use from the UK energy data we can see from the left hand graph that decades of falling heat loss from UK houses has spectacularly reversed in the last three years of data.\u00a0 The right hand graph shows that the average temperature people heat their houses to has showed a consistent upward trend even as the average outside temperature has increased.<\/p>\n

\"graph1\"<\/a>At first sight there is no obvious explanation for this recent pattern, although 2010 was on of the cold winters we have had, so was 2009.\u00a0\u00a0\u00a0 However, the overall data is broken down into individual components (walls. Windows, roof etc.)\u00a0 Only the heat loss through walls has shown a continuing fall.\u00a0 The heat loss though windows and by ventilation has increased dramatically with other areas such as roofs showing minor increases.\u00a0 It looks like the recent run of colder winters has had households opening their windows more frequently to combat mould and damp.\u00a0 This a live issue of debate in our household, is it better to air the house and let cold air in and hopefully damp along with heat out?\u00a0 Or does make the whole place colder and therefore damper?\u00a0 There is a solution to this that is a mechanical heat recovery system which removes stale air passes it through a heat exchanger and sends 90% of it back into the house.\u00a0 However these are disruptive and expensive to retro fit.<\/p>\n

The second set of graphs show long term energy price trends.\u00a0 The left hand graph shows the actual price and the second right hand graph shows the prices relative to 2011 prices (2011=100).<\/p>\n

\"graph2\"<\/a>Again this data shows some surprising trends. Whilst there has obviously been a very high upward trend in recent years the price some types of energy are not at all time highs.\u00a0 The data ends at 2011 and it should be noted that prices have gone up more since.\u00a0 Also gas and oil prices have been higher in the past.\u00a0 The gas price data is explained by the fact that it was higher when there was no north sea gas and we used town gas.\u00a0 This cheap north sea gas explains the gas and electricity price falls in the late nineties, not privatisation of the gas and electricity companies which piggy backed on the back of that cheap resource.\u00a0 But as the gas has started to run out and the oil price leapt, that trend has gone into reverse with a vengeance.\u00a0 Oil prices (used for heating) were also higher in the past.\u00a0 This is also surprising to me.\u00a0 Not even the record price of oil in 2008 could undo the 1979\/80 price.<\/p>\n

The effect of these recent price increases can be seen in the next set of graphs showing on the left the % of households in England in fuel poverty and on the right the % income spent by all UK households in different fuels.<\/p>\n

\"graph3\"<\/a><\/p>\n

What can we conclude from this UK energy data?\u00a0 Despite energy price increases we are still very wasteful with energy and for many of us its still too cheap.\u00a0 There are a large minority however, who are struggling since for them ironically energy prices are far too high.<\/p>\n
