I was in England when I wrote this post and I am not joking when I say that today we had multiple mini-blackouts. Thanks to modern technology and surge protectors my hardware is safe and my blue-screen-prone operating system is still running. In my eyes, blackouts are going to become something more regular if we, or the governments, do not tackle the national electricity supply. Thanks to all the environmentally active organisations, parties and people, many modern countries start moving from fossil (and unfortunately nuclear) to renewable energy. Germany is making shining example by shutting down many nuclear plants and now has to import more electric energy from abroad. So the energy creation is not the major issue, it is rather the energy transportation. Moving energy across a country or even a continent is very difficult and needs more than one copper wire. Redundancy, transformer plants and distributing stations need to be implemented to pass the phases to all buildings. In Germany, engineers point out that in the case of all nuclear plants being shut down, southern Germany is running a very high risk of not being able to receive all the energy needed since the infrastructure is not in place to pass it from the coastal wind farms to the Alps. In England something similar exists with supplying Scotland, since there are only two connections linking the countries, which means a single failure could cause moving blackouts. Recently something called "smart grids" has been mentioned, but what are they and how will the be implemented and how will they save the energy transportation problem?
So are we? To be honest, I do not know, but I do consider the possibility of extraterrestrial life. Nevertheless, our universe is not one of the smaller ones. It is nearly 14 billion years old and still expanding, yet life on earth has only started three and a half million years ago. Who knows how many other planets are in our universe or even our solar system capable of providing life worthy conditions? Some scientists believe that there is a very high chance of live (i.e. on Gliese 581g, which is only 20 light years away). But what would this mean for us? Should we be worried and start arming our terra-defense-sysem? Should we build bunkers and invest in weapons of foreign-life-destruction?
