Historical and potential future contributions of power technologies to global warming

摘要: Using the mathematical formalism of Brazilian Proposal to IPCC, we analyse eight power technologies with regard their past and potential future contributions global warming. Taking into account detailed bottom-up technology characteristics define mitigation each in terms avoided temperature increase by comparing a “coal-only” reference scenario an alternative low-carbon scenario. Future potentials are mainly determined magnitude installed capacity temporal deployment profile. A general conclusion is that early matters, at least within period 50–100 years. Our results conclusively show better proxy for impact on climate change, numerous short-term comparisons based annual or even cumulative emissions may be misleading. Thus, our support extend policy relevance sense not only between countries, but also could undertaken basis rather than as practiced today.
