Yeah, in the UK. Over ten years, which means an average of $17.2 million per year not counting inflation, which won’t mean all that much anyhow.

Ok, so this saves $17.2 million per year in the UK. There are 23.6 million households in the UK. This means that the average household saves $0.72 per year!!!

I don't know if the folks who calculated the cost savings figured in the price difference between incandescent bulbs and their CFL/LED replacements, but I can assure you that it is far more than $0.72.
