WHAT NEW ENERGY CAN DO

New IEA report shows technology can transform energy system but emphasises need for decisive policy action now; Energy Technology Perspectives 2012 says with right policies, shift to clean energy can more than pay for itself

11 June 2012 (International Energy Agency)

“A host of new technologies is ready to transform the energy system, offering the potential to drastically reduce carbon emissions, enhance energy security and generate a huge investment return, the International Energy Agency (IEA) said in Energy Technology Perspectives 2012; Pathways to a Clean Energy System (ETP 2012)…[which] explains how to enable and encourage technologies and behaviours that together will revolutionise the entire energy system and unlock tremendous economic benefits between now and 2050…

“The technological revolution will not be cheap, but the long-term benefits far outweigh the costs. ETP 2012 presents an investment plan that more than pays for itself through fuel savings by 2025. And the savings would triple by 2050: An additional USD 36 trillion of investment would be required to overhaul the world’s current energy system by the middle of the century, but this would be offset by USD 100 trillion in savings through reduced use of fossil fuels.”

“ETP 2012 presents a 2°C Scenario, which lists the energy technology choices that can ensure an 80% chance of limiting long-term global temperature increase to 2°C. The plan leads to a sustainable energy system featuring diverse sources, low-carbon electricity and an expanded infrastructure. The system would be smarter, more unified and more integrated than today’s, and ETP 2012 assesses the increasingly sophisticated low-carbon technologies that get the most out of energy options, showing how the world can effectively and efficiently adopt solutions ranging from energy storage to flexible generation.

“Improved energy efficiency offers the greatest potential for boosting energy security and reduced carbon emissions, and ETP 2012 includes a variety of technological and policy options that would cut the global economy’s per-unit use of energy by two-thirds before 2050…Fossil fuels would not disappear, but their roles would change…The book makes clear that low-carbon fuels and technologies depend on immediate infrastructure change to build in the flexibility the new approaches require…”
