Energy vectors: “How we convert natural energy into man-made energy”

Full screen view

After making direct use of natural energy (such as using the wind to propel a boat forward), then converting it into more useful forms of energy (in mills, for example), humans discovered that they could convert natural energy into other forms of energy that did not exist in usable form in nature.

Examples of this are electricity and hydrogen. We call these two man-made forms of energy "energy vectors", because both of them enable energy to be carried and can then be converted back into any other form of energy. Now, while using energy vectors does not cause pollution in itself, creating these vectors from fossil fuel sources does create pollution – a lot of it.
