A helpful overview of the leading technologies to replace fossil fuels, improve electricity generation, and make our energy-dependent society sustainable.

Interesting overview of low carbon energy sources that can reduce our dependence on fossil fuels. Though this article is a bit dated and superficial, it is generally factual and offers a fair introduction to this field. More depth, combined with better sourcing and context would have helped make it a more definitive resource.

Excellent overview of the technologies we are looking at over the next two weeks. There's some info here about financial feasibility -- though not enough.

This is actually a collection of articles tied together into a "roadmap". However, the big picture provided by the editors remains unexplained. How did they make their choices? How were the "What We Need by 2050" numbers chosen? I remain unconvinced.

This story is informative, and well-sourced. It gives us hope and choices because it’s really hopeless to observe the slow development of energy alternatives. New sources of energy are desperately needed to compensate for the eventual disappearance of existing fuels as well as to slow the build-up of climate-changing greenhouse gases in the atmosphere.

A good broad overview of the kinds of technologies that will be needed to meet our energy needs in the future. Thinly sourced, but at least it lays out the field...

It is good to see the 40 year scope of this story, but I think it is pretty limited in its analysis and in giving true context.
