First, what is a data centre? It's simple, it's a large array of computers with very powerful graphic cards. If you have a computer for gaming (or your son has one), you know that they run hot, and need a lot of cooling. So the first thing is that data centers need a lot of cooling, it can be open or closed, but in either case data centers need a lot of water – because in 99% of cases water cooling is the best solution. The next thing is that data centers need energy, a lot of energy, first to run their graphic cards but also to cool the cards. Right now the ONLY solution is the grid, there is no other solution. You could build a coal plant next to a data centre, but the fundamentals are the same, data centers are large energy consumers, full stop. There have been "stories" about nuclear reactors for data centres, but the world is at least a decade away from such a thing happening. Data centers are ubiquitous, far more than people believe ...
This is not from me, but from a Canadian based, American political scientist called Tim Snyder, who a few months ago, at the Council of Foreign Affairs brought out this new "definition" of a superpower that does almost anything to destroy itself. The story of Trump and his followers, carpetbaggers and wannabe dictators, but of another democracy that "gave up" now the context is different but some of the elements are surprisingly similar in the outcome. The Treaty of Vesaille forced upon Germany and its population massive repayment obligations that were nearly impossible to achieve – which was largely the objective. It is important to note that Germany in the 1920s was simply the "center" of scientific research – just look at the Oppenheimer movie to understand the importance of the country to fundamental research. The first world war was not a "global war" in the same way as WWII was, conflicts were very regional, granted all over Europe, but ...
