LED lights making dent in UK energy demand

Installing a single low-energy LED bulb may make a trivial contribution to cutting the carbon emissions that are overheating the planet. But if millions choose LEDs, then with a twist of the collective wrist, their efforts will make a small but significant dent in the UK's energy demand. Studies show making products more efficient has - along with other factors - already been slightly more effective than renewable energy in cutting CO2 emissions. The difference is that glamorous renewables grab the headlines.
