How a Solar-Hydrogen Economy Could Supply the World’s Energy Needs

[snip]

Overall, Abbott’s message is that there exists a single technology that can supply the world’s energy needs in a clean, sustainable way: solar-hydrogen. The difference in his approach compared to other analyses, he explains, is his long-term perspective. While nuclear power is often cited to be the economically favorable technology in the short-term, Abbott argues that the long-term return on nuclear power is virtually zero due to its limited lifetime, while solar-hydrogen power can theoretically last us the next one billion years.
