How about 100% from renewable sources? A new report by PriceWaterhouseCoopers suggests Europe could be powered entirely by renewable sources, albeit at substantial cost of transition, especially on inter-continental transmission:
A "super-smart" grid powered by solar farms in North Africa, wind farms in northern Europe and the North Sea, hydro-electric from Scandinavia and the Alps and a complement of biomass and marine energy could render carbon-based fuels obsolete for electricity by 2050, said the report.While the costs and challenges are great, those of clinging to the fossil economy would be much greater. But what is remarkable, of course, is that the modern industrial economy of Europe, roughly the same size as that of the United States, could be run entirely on renewable energy.
The goal is achievable even without the use of nuclear energy, the mainstay of electricity in France.
Thus, today's announcement by President Obama to expand off-shore oil drilling in the United States is especially disappointing.
