This is a very confusing subject so both journalists, politicians, as well as the general public, can easily be misled by numbers thrown around which (deliberately or by inability to discriminate) and often confuse energy with electricity. You have to think in tiers or hierarchies, and be very careful not to confuse one level with another.
1. World energy use.
2. National, federal or continental energy consumption.
3. Sector total energy use (e.g. transportation, industry, service/commercial, domestic/residential).
4. Sector by fuel type (e.g. natural gas, coal/coke, lignite, petroleum, renewable, electricity) in that country or federation.
5. Fuel type (e.g. electricity) split by end-use (e.g. space heating, space cooling, water heating, refrigeration, cooking, home electronics, lighting).
You often also have to combine statistics from different areas and separate tiers to get the complete and accurate picture. Here I’ve used EuroStat: Panorama of Energy [1] and the EuroStat statistics for the lighting part of home electricity cited in the European Commision’s Residential Lighting Consumption and Saving Potential in the Enlarged EU [2] to get the national energy consumption (level 1), residential (pritate households’) energy consumption (level 2), residential electricity consumpion (level 3) and lighting part of residential electricity consumption (level 4) for EU-27 2006 in 1000 TOE (Tonne Of Oil equivalent):

Of this 0.76% the preparatory study by the EU Commission’s own consultants showed that the share of household incandescent lamps has decreased from 85% in 1995 to 54% 2007. [3]
Based on surveys of 500 consumers in 11 countries, the EU-27 average share per household 2007 was estimated at:
• 54% of the lamps incandescent (and decreaseing)
• 18% of the lamps low-voltage halogen (and increasing)
• 5% of the lamps mains-voltage halogen (and increaseing)
• 8% of the lamps linear flourescent
• 15% of the lamps CFL with integrated ballasts
Note that incandescent lamps were expected by the preparatory study to keep decreasing dramatically, even in the “business-as-usual” scenario (= without a ban)! [3]
• We also have the sooner-than-expected introduction of decently functional lower-wattage mercury-free LED-lamps.
And after the intensification of the CFL propaganda, all the energy-saving tips flooding the media and internet these last 2 years, all the freebie campaigns and the climate change threat, it’s probably less today, but let’s for simplicity’s sake say the incandescent lamp share is still as high as 50%.
Half of 10% = 5% of domestic electricity.
Half of 2.94% = 1.47% of total domestic energy use.
Half of 0.76% of = 0.38% of EU total energy consumption.
Of this little fraction, the European Commission hopes to save 65-75% by forcing people to switch to CFLs. This makes:
2.35 – 3.75% of domestic electricity.
0.96 – 1.1% of total domestic energy use.
0.25 – 0.28% of EU total energy consumption.
Using the more realistic figure of CFLs saving closer to 50% (with light deprication, power factor, ballast loss, heat replacement effect, poor quality imports, wrong useage etc. taken into consideration) we get:
Half of 5% = 2.5% of domestic electricity.
Half of 1.47% = 0.74% of total domestic energy use.
Half of 0.38% = 0.19% of EU total energy consumption.
Not exactly close to the 2020 goal, is it?
And not all of the remaining incandescent lamps can be replaced by CFLs. The preparatory study explains why:
“…some customers have a few light points left where they prefer to keep the GLS due to barriers for CFLi as explained in chapter 3 (e.g. requirements to color rendering, sparkling effect etc.) or because of the lamp has little usage such as in cellars, staircases or storage rooms and where full lighting is also needed immediately.” [3]
