The discussion about energy perspectives beyond 2020, up to 2030 and eventually 2050 has started. There seems to be a verbal consensus on the necessity of ambitious climate change mitigation policies, without a convincing perspective of the necessary policy decisions to be reached in due time. Methods to achieve greenhouse gas reduction as well as energy security vary from aiming for 100% renewable energies and setting up appropriate policy frameworks to implementing a mix of renewables comprising so-called clean fossil and nuclear energy. This book provides an analysis of the different approaches and the reasons why there is no sustainable alternative to aiming for 100% renewables – and how this vision could come true. The book provides an overview and in-depth analysis of a vital debate. It describes how the present policy framework with 2020-targets for the share of renewables, for increase of energy efficiency and for greenhouse gas emissions reduction was developed and how it has been implemented so far. Furthermore, it describes and analyses the emerging debate about the future of our energy system and the necessary next steps and targets leading up to 2030.

This outlook highlights climate-safe investment options until 2050, policies for transition and specific regional challenges. It also explores options to eventually cut emissions to zero.

India 2020 is about to become a reality. Are we ready? As Dr Kalam and Y.S. Rajan had contended in their landmark vision document, India 2020, India has steadily moved towards becoming one of the top five economic powers in the twenty-first century. India’s growth story has seen new opportunities and emerging technologies that make faster and more inclusive growth viable. In Beyond 2020, Kalam and Rajan argue that a renewed policy focus is now needed for agriculture, manufacturing, mining, the chemicals industry, healthcare and infrastructure to invigorate these sectors and boost economic growth. India can still make it to the list of developed nations in a decade. This timely book provides an action plan for that transformation.

This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources - bioenergy, solar, geothermal, hydropower, ocean and wind energy - as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies, and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector, and academic researchers.

The use of renewables is spreading rapidly. Over a quarter of global electricity is already generated from solar, wind, hydro and biomass energy. With costs falling significantly, renewables are booming, helping to avoid the major climate change risks associated with fossil fuel use in power stations, homes and vehicles. But can we get rid of all of these dirty energy sources – and nuclear power, as well – and deliver 100% of our energy from renewables? Or are renewable energy systems inherently unreliable and expensive, given the need to deal with their variability? In this timely analysis, leading energy expert David Elliott tackles these issues head on and asks to what extent renewables can deliver a technologically and economically viable energy future. Exploring both the progress and problems of renewables against a backdrop of rising energy demand, he argues that, on balance, they do seem to be living up to their promises. With renewables rapidly expanding across the globe, and China now leading the pack, a renewable future could really be on the horizon.

The discussion about energy perspectives up to 2050 and beyond has started. There seems to be consensus that ambitious climate change mitigation policies are necessary, whereas proposed solutions vary from aiming at 100% renewable energies and setting up appropriate policy frameworks to a mix of renewables with so-called clean fossil and nuclear energy. Provides an analysis of the different approaches and the reasons why there is no sustainable alternative to aiming at 100% renewables and how this vision could come true. An overview and in-depth analysis of a vital debate, describing policy options and their impact on Renewable Energy development and deployment in Europe.
