I want to know the answer to the following question:
How much energy does the incandescent light ban in Europe save each year?
All the background I'm provided with is that "Since incandescent light bulbs use more energy than alternatives such as CFLs and LED lamps, many governments have introduced measures to ban their use, by setting minimum efficacy standards higher than can be achieved by incandescent lamps.". Is that enough to answer the question?
Answer: no
