There’s nothing like a warm fire when it’s chilly outside. Oh, it’s gone out, and I’ve got no coal left!
I think I might have to find an alternative energy.
Although coal is great for a nice cosy fire, there’s only so much of it we can dig out of the ground and burn before it eventually runs out.
That’s because it’s a fossil fuel, which was formed millions of years ago from the remains of plants and animals, so we can’t make more of it after we’ve used it up.
I’ll see if I can find a different fuel, one that can make heat or electricity but without running out. What’s called a renewable energy!This turbine is powered by the tide going in and out.
The water rushing through the propeller generates electricity.
The water from this hot spring is being warmed by rocks heated by volcanic activity deep under the ground.
The steam from these rocks can also be used to power generators in a power station. This is called geothermal energy.
The wind is strong here, which is great for drying my wetsuit but also for powering wind turbines.
And solar panels can generate electricity from the Sun.
All these sources of energy are great, not only because they’re renewable, but because they don’t produce harmful gases that can cause pollution and climate change like fossil fuels do.
And talking of burning, I think I’d better put a sun hat on!
