Tuvalu plans to be first 100% solar-powered nation
Only three feet above sea level, the island of Tuvalu has suffered in the wake of rising waters -- and even went so far as to sue the Bush administration for their refusal to do anything about carbon emissions. (...) Tuvalu's 12,000 residents have decided to fight back. The world's fourth-smallest nation recently announced that it would power the entire island with 100% solar energy by 2020. The ambitious project is expected to only cost around $20 million (not bad for an entire nation -- but still a hefty $1,666 per resident!) and serve as a model of sustainbility for the rest of the world.
