Tiki's Guide to Energy

Energy is special. There's lots of it about and it's very useful.
Why? What's so special? Here's just a few reasons.
- it lets me swim
fast and catch my fish
- it gets you out
of bed in the morning
- it means that birds
can fly, tigers can roar, wind can blow
- it makes the sun,
the moon and stars shine
- it makes plants
grow -- food (= stored plant energy) for animals
- it makes cars move,
factories produce things, light bulbs glow, planes fly and your
computer work.
 I'll
bet you can think of many more!
Without
energy, there would be nothing: no life, no movement, no light,
no heat, no you, no me… nothing.
But
there is a problem with energy. Some people have got used to using
far too much of it. This means that there's not enough for everyone.
And using some kinds of energy causes terrible pollution and makes
the Earth's climate get hotter.
Confused?
No worries. Welcome to my new Energy Guide in which I take you
on a journey through energy and, I hope, help you understand it.
