It is technically possible to have more energy officient home (many cannot afford to replace an old boiler by a more efficient or to retrofit thermal insulation) but industrial processes still use huge amount of energy and with energy prices higher than in the rest of the world UK will not become an industrial country again. LED lights is a blessing and a curse- instead saving energy people emit more light for the same money. Outdoor spaces are well lit throughout the night creating light pollution.
