Energy 1: How you live at home.

If you turn energy-gobbling things off when you're not using them, they don't use energy. Simple. So you're not causing pollution. Just get into the habit of flicking that switch!

Instead of turning up the heating when you're feeling a little cool, why not just dress more warmly? If animals like seals and penguins can keep warm in freezing water, snow and ice (penguins just have a layer of special warm feathers and an inner layer of fat), you should be able to keep warm by adding your own layers. Having the heating set just a degree or so lower can make a surprising difference to how much fuel gets burned (and how much pollution is made). It is also cheaper for your parents who pay the bills!

Air conditioning is a real energy-guzzler too. A simple fan uses very little electricity and helps your body cool itself. The breeze from the fan feels cool because the sweat on your skin evaporates.

Before the days of 'cheap' energy, people simply avoided living in places that got very hot in summer. Now people live in the hottest and coldest places on Earth (including the South Pole) — but they can only do so because they burn fuel to modify the temperature inside their buildings so that they are comfortable.
