When we speak about renewable power we’re referring to energy that delivers vitality from sources that won’t be depleted due to our use of them. One other potential role for technological change economists is essential assessment, synthesis, and extension of the present empirical literature on learning curves in power technologies. This consists of enhancing the flexibility of assessment fashions to include learning effects in an economically coherent manner, as well as new empirical research avoiding the pitfalls of previous studies and that can probably be included into computational models. Evaluation fashions would also profit from improved therapy of technology spillovers and the opportunity cost of R&D directed toward carbon mitigation expertise. Finally, given the long-term nature of the climate problem, empirical, analytical, and numerical analysis on the therapy of lengthy-term discounting in assessment fashions and its affect on technological change would be useful.
