Plus these simple measures save money, and in the modern world it may be this and not any wild hippy thoughts of saving the environment which spurs change. Uniform insulation of loft insulation would save around 460 million worth of energy for the UK alone. Put a jacket around your hot water tank and contribute towards saving enough energy to power 60,000 homes for a year worth around 21 million. Install cavity wall isulation. If this was adopted by every UK household it would save enough energy to power 1.4million households for a year.
Walls are where most energy is lost.
Run your washing machine at 40 degrees instead of 60 and save around a third on energy. Take a shower instead of a bath. It uses around two-fifths of the water and so takes less energy to heat. Try and recycle as much as possible, it cuts down on the production of green house gases. The swift kick up the backside the world seems to have received will surely see more effort to utilise renewable power sources such as the wind, water and sun.
