    The need for global and regional clean energy technology investments by 2050 are evaluated in climate policy scenarios with the bottom-up global ESAP TIAM energy system model. The impacts of the assumed regional CO2 storage potentials as well as bioenergy and wind power potentials on investments are also investigated by sensitivity analysis. The results of the study indicate that the demand of both wind and bio energy as well as the utilization of CCS will strongly grow under strict climate policy scenarios. This can be seen both in terms of electrical capacity and annual capital costs. Although the falling fossil base electrical capacity will be relatively large until the mid of the century, its monetary value in term on annual capacity costs will be relatively low.
