The International Energy Agency (IEA) published the Energy Technology Perspectives (ETP) 2014 last June. The document is the IEA's biennial flagship publication concerning energy technology solutions for a sustainable future. The ETP 2014 states that a revolutionary reversal of shares of power sources needs to occur to achieve almost zero carbon generation in order to contain the atmospheric temp...

One lesson from the German Energiewende is that low-carbon energy solutions cannot come from a short list of innovations and technologies. Crucial is the system integration of low-carbon technologies.   For example, photovoltaic has become a promising technology as its investment costs have sharply declined. Therefore the number of competitive markets and market niches are largely growing a...

According to SPM of IPCC AR-5 WG1(1) cumulative (anthropogenic) emissions of CO2 and global mean surface temperature response are approximately linearly related. It indicates that stabilization of the global surface temperature requires almost zero emission of CO2. Considering that more than 85% of primary energy mankind depend upon are fossil fuels, we mankind are required to make drastic efforts...
