On Saving Energy

Humanity is for ever energy hungry. We always were, even in prehistoric times. Of course, then the energy needed was much smaller, than what we need today. Still it needed a lot of human energy to collect the wood and to use sticks or flintstones to ignite the fire. It was also not the most efficient way to utilize energy. It seems to be a paradox, that on the one hand this world is inundated by energy and on the other hand we human beings never have enough energy. The energy of the sun is...

Here are some of the most interesting ones. The first one deals with the rise in demand for small wind energy turbines in...

Summer Time and the Waters are Flowing!

It is summer again, at least in the northern hemisphere, and it is hot, very hot indeed. In the southern part of France, a couple of weeks ago, a devastating flood occurred. 19 people died. Now floods are always happening and in some parts of the world it is totally normal for floods to happen during the summer, but not in southern France with it’s Mediterranean climate. In the south of France it should be quiet dry in the summer. It could be regarded as a freak of nature if this incident...
