DESERTEC Plugin for Google Earth

The plugin http://www.desertec.org/de/aktuelles/newsletter/plugin/ has several layers (surfaces); every form of the renewables can be displayed separately or in combination. You get a good overview which technologies can be ideally applied. Solar towers, as used, e. g. by the awardees of the DESERTEC Award, can also be used on more difficult surfaces and are a good option for many regions in the world.
