Well, I guess you just have to live with the fact that you live with other people. What's so bad about "political requirements"? This is just an expression that means that the requirements come from the process that you and your peers have chosen for making decisions that affect all. What other requirements should there be? I often write requirements for projects. The initial and most important requirements are usually non-technical: after all, I'm not in the business of creating technology for its own sake, I create it to solve somebody's problem. That's usually a person, and the requirements are non-technical. Part of my job is to translate that into technical specs. This is not different with energy creation and waste disposal. This is a fundamentally non-objective problem, as there is no way to objectively compare different options. Trying to "do a technical evaluation of the true cost of an energy source" is a contradiction in terms. The "true cost" is a social problem, not a technical or economical one. Technical and economical aspects play an important role, and you better get them right before you go on to the more subtle aspects, but they don't play the major role. This is really about something else... how do we want to live? This is not a technical question, and it can't be answered with only technical means.
