I'm looking for data which will tell me what the energy is for solar (and other clean energy solutions) on an average per country basis for every country in the world. Where should I look?
The site that I use is http://mapserve3.nrel.gov/PVWatts_Viewer/index.html, you can find data using zip code, it is down today hopefully it comes back up. Another site is SWERA http://swera.unep.net/index.php?id=dni_nrel_mod&no_cache=1&dataprovider=8&datatype=4,70,79&energycategory=81&resolution=medium Or start searching for DNI (Direct Normal Irradiance) or NREA (National Renewable Energy Laboratory). There is a wealth of information out there you just need to start searching.
