The European Climate Foundation (ECF) has just published a ground-breaking study put forth by McKinsey. Conducted in consultation with corporations and other organizations from the renewable and electricity sectors, it explores options for a carbon-free European power sector by 2050. The study outlines plausible ways to achieve an 80% emissions reduction target compared with 1990 levels from a broad European perspective. Such a power supply could be realized by further developing and deploying technologies that are already commercially available or in late stage development, and by expanding the trans-European transmission grid. The study calls for collective action before 2015 as a prerequisite, starting with electricity decarbonization.
