The Energy Report: 100% Renewable Energy by 2050
WWF has a vision of a world that is powered by 100 per cent renewable energy sources by the middle of this century. Unless we make this transition, the world is most unlikely to avoid predicted escalating impacts of climate change.
But is it possible to achieve 100 per cent renewable energy supplies for everyone on the planet by 2050? WWF called upon the expertise of respected energy consultancy Ecofys to provide an answer to this question. In response, Ecofys has produced a bold and ambitious scenario - which demonstrates that it is technically possible to achieve almost 100 per cent renewable energy sources within the next four decades. The ambitious outcomes
of this scenario, along with all of the assumptions, opportunities, detailed data and sources, are presented as Part 2 of this report.
The Ecofys scenario raises a number of significant issues and challenges. The Energy Report investigates the most critically important political, economic, environmental and social choices and challenges – and encourages their further debate.
How are we going to provide for all of the world’s future needs, on energy, food, fibre, water and others, without running into such huge issues as: conflicting demands on land/water availability and use; rising, and in some cases, unsustainable consumption of commodities; nuclear waste; and regionally appropriate and adequate energy mixes?
Unfortunately, we can't wait till 2050. We needed to have done this twenty years ago.
As Kevin Anderson points out, we have to start with radical reductions on the much-more-elastic demand side if we are going to get anywhere close to have any glimmering hope of avoiding beyond-catastrophic consequences. (Catastrophic consequences are already baked into the cake, at this point.)
