Energy System Change And External Effects In Climate Change Mitigation

摘要

There are many studies of the engineering and economic feasibility of a low carbon energy system being achieved over the present century. The many studies of industry, governments and scholars point to scenarios of global carbon emissions from energy use in the range from ≤ 0 to 60 gigatons per year by 2100, as compared with approximately 6 gigatons per year today. Such extraordinary divergences stem from the types of the energy systems assumed for the scenarios, and on the various economic factors and policies that determine the directions of technology development and choice.
