together over twe of renewable and about lotwe of nuclear power plants would be installed or five and half times more than the total installed capacity of all power plants in the world the interesting feature is that half of all of these plants would be built in the now developing parts of the world and most of them as new capacity expansion and not as replacements of ageing power plants first there is a potential risk of lockin in the traditional technologies if the needed new capacities are not built with the best technologies in other words there is a huge incentive for the capital to be attracted to the newest technologies and for there to be free access extended to those in the currently developing parts of the world for further discussion see chap second there are real possibilities in developing countries of leapfrogging to the most advanced technologies as the market is huge and would likely lead to large cost reductions and performance improvements see also chap
