Here in Australia we are doing a good job of getting solar onto our train stations. However, South Africa has just raised the bar by opening what they are calling the first solar powered airport (though I think India was doing something along these lines too) . Here's an excerpt:
South Africa has opened the continent’s first solar-powered airport in Western Cape. George Airport which serves over 600,000 passengers annually, has launched a clean energy project which, during its first phase, will contribute around 40% of the airport’s electricity needs. Once completed, the airport is expected to be totally independent of the national grid.
The airport will generate its electricity by harnessing energy from sun tapped through photo-voltaic panels which were installed at the cost of almost a million dollars. Airports Company South Africa, which runs the airport, hopes George Airport will be the first of nine airports under its control to run on solar energy as it chases the lofty goal of running airports fully on renewable energy.
