From commonsense thoughts, need for energetic transition is not difficult to understand, but when it comes to its economic counterpart the choice is less obvious. There is a trade-off between economic and environment efficiency, because from now-on we are not able to produce enough cheap renewable energy to reach energy's demand. Here we will focus on the economic toolbox available to mitigate global warming and enhance the use of green energies through a not so common framework in environmental economics, vintage capital model. It is relevant for our question because it allows to invest in old technologies, as some countries still build coal-fired power plants, and take into account the cost of scrapping obsolete capital. By allowing investment in the energy sector and in the production sector we aim to analyze the bargaining between pollution and energy efficiency, and the keys to speed-up energetic transition and reduce global warming.
