There have been a number of significant changes in technology since the millennium including:

1. A considerable proportion of incandescent bulbs have been replaced with low energy bulbs.

2. Almost all televisions and computer monitors in 2000 used CRTs but the majority in use today are flat screen.

3. A larger number of DVD players and satellite receivers are in use - which are rarely switched off.

4. A large increase in the number of households which own computers and laptops are now more popular than desktops.

5. A decline in the number of video recorders, Hi-Fis, and stereos in use - which were often left on standby for long periods of time.

6. ADSL / cable modems and wireless routers were rare in 2000 but most homes with computers now have them. Power consumption of individual devices is low but they are left to run continuously for months on end.

7. Game consoles are much more popular than in 2000.

8. Television programmes which attract audiences of tens of millions are now much rarer than in the past as viewing has fragmented across satellite channels and the internet. No longer do the massive surges in energy consumption from millions of viewers switching their kettles on all at once before the beginning, after the end, or during commercial breaks happen as frequently.

Have there been any studies into how these changes in technology have affected energy consumption?

Perhaps take a look at "DUKES" for the last two decades and contrast that with the decline in heavy industry/manufacture - and then look at what the "loss" has been replaced with ?

I have looked at DUKES but the figures are not as precise as what I want because I'm looking at changes in consumption resulting from changes in domestic appliances.

Has the IET carried out any investigations into how the aforementioned changes in domestic appliances have affected domestic energy consumption and peak power surges?
