What Is Possible and by When?
To what extent can low-carbon energy technologies, particularly renewable energy technologies combined with energy efficiency improvements, contribute to the 2°C target? And by when? Several relevant scenarios present robust projections and provide some insight into the probability and margins of predicted future developments.
2.1 Relevant and Authoritative Scenarios
Scenarios are the result of modeling possible future developments in energy supply and demand systems. In general, they are highly dependent on assumptions and other inputs about a number of parameters, including energy prices, costs, ...
