See The City By Starlight by Rebecca Hunter

We’re trained to fear the shadows, to cower at things that go bump in the night. Our days are a continuous run from the dark, with omnipresent lighting giving each of our waking hours the same artificial glow.

But it’s time for a change of perspective. We need to confront our fears and take on our dependency on bulbs. Flip the switch whenever you leave a room, and if you’re really adventurous, embrace the dark by spending the evening gazing at the stars.

It might seem like a small action, but it has a big effect. Switching off the lights – like turning the television off at the mains and using cooler washing cycles – helps to reduces emissions from the energy supply sector, which in 2013 produced 178.5 million tonnes of CO2. It’s also a money saver, UK households spend £1.9 billion a year on lighting so flipping your switches is one of the easiest ways to be kind to the planet and your wallet.
