Remember this post, about Sweden’s new year’s resolution to give up oil by 2020?
According to Jeremy Faludi at Worldchanging.com, it might not be as difficult as you think.
For example, currently, 6% of Europe’s electricity generation is from renewable sources. If they wanted it to be 100% by 2025, they should expand renewable energy generation by about 15% per year, every year, compared to other power sources. (This does not mean 6% now, 21% next year, 36% the year after, etc. It only means 6% now, 6.9% next year, 8% the year after, etc.) This sounds small, and in fact is less ambitious than their current plan to grow renewables from 6% to 12% by 2010. That would require increasing renewables’ share by 17% per year. But if Europe kept growing its percentage of renewables by 15% per year until 2025, they would be at 100% green power. Perhaps such a policy would be both more ambitious and easier to achieve.
