Energy Explained
Energy is in everything. It makes everything happen.

We buy energy, sell energy, eat energy, waste energy, talk a little about conserving energy, fight over energy -- and kids use it to chase pigeons. You can't understand animals, biology, physics, chemistry, electronics, volcanoes, or any field of science, engineering, or economics, without understanding how energy behaves.

At this website you shall become the enlightened energy know-it-all. The basics are here. The wonder is here. Who knows where this knowledge will lead you?

Things Change (Thanks to Energy)
Energy is about change. Nothing happens without energy.

It can be transferred from place to place. It can change form - be transformed you might say. Every time energy moves or changes, something happens. Something gets hotter or colder. Something moves. Something falls, breaks, blows up, rusts, or crumbles to dust. Someone takes a breath, gets a thought, reads a web page and laughs.

To study energy is to study what happens when energy moves or changes. If you know the basics you can predict the future. We engineers do it all the time - and we're often right. When we're not, everyone knows about it, especially when things explode or fall with a bang.
