Energy
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton.

If you take a bale of hay and tie it to the tail of a mule and then strike a match and set the bale of hay on fire, and if you then compare the energy expended shortly thereafter by the mule with the energy expended by yourself in the striking of the match, you will understand the concept of amplification.
William Shockley

The real key word that triggers my rage is the word "energy". When people start talking about positive or negative types, for instance, negative energy — what are you talking about? What do you mean? Let's think about it, what does energy mean? Well, we know what it means, you know, energy from petrol when it's burned and moves a car and makes it move, it's like this. "This room has positive energy." Now, where the fuck is it going, then? It's not moving. It's covering up such woolly thinking, such pathetic nonsense.
Stephen Fry on New Age use of the word "energy".

It is important to realize that in physics today, we have no knowledge of what energy is. We do not have a picture that energy comes in little blobs of a definite amount.

Scarcity of fresh water is of growing concern in the Mediterranean area due to urbanisation, irrigation and changing rainfall patterns. The influx of millions of Sun-seeking tourists puts even more pressure on limited water resources during the summer season.
