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 "In the Europe the EC has calculated that the ban contributes 5 to 10 billion euros to the economy and saves 40 TWh of electricity every year, translating in CO2 emission reductions of 15 million tonnes.". Is that enough to answer the question?
