We need to be enthusiastic, definitely, and we need to get rid of fossil fuels as quickly as possible.
This being said: Although I am strongly in favor of diversifying the types of energies we rely on ands develop the renewable branch as much as possible, I would like to get a deep comparison between all energies, a comparison that also accounts for the energy and ressources needed to build the powerplants (or devices) and to dismantle them. This is something I have never read anywhere. I think we may get surprises from there, which could also indicate where important problems that need to be solved are.
To be clear and emphasize: I am not saying green energies are bad. I am strongly in favor of them. What I say is that we may need to tune down a little bit our enthusiasm, which is different. More research is probably needed.
I think that research is always very useful and important, and I mean research in all directions.
However at the same time I really support companies like BYD which (apart from actually investing a lot into research) also throw real and reliable products on the market, because I think there is a reason that we say "learning by doing" and not "learning by theory (only)". Yes, I think we have to research, but we also have to act and test things in practice. :)
I forgot to answer on this:
Deal, I agree, that would be interesting, but ... then we should not only consider the costs to construct the power plants, but also the estimated future costs, caused for example by the storage or recycling of the produced waste and also caused by the removal of old unused power plants.Totally in phase with you :)
And yes, you wrote "dismantle", too, which I didn't notice at first. :-)
