The Tyranny of Realism- to what extent is our present and future energy development constrained by the past? This is a question that our most recent report seeks to answer. "This volume seeks to prompt balanced discussion of a number of themes, but also presents a line of argument, that there is one decision that is unequivocally and urgently required: to prioritise the deployment of renewable energy technologies in the short term, immediately and ambitiously, and increase the share of renewable resources in the energy mix as rapidly and extensively as possible into the long term".
