Guess the most and least polluting states of the world, measured in carbon dioxide per capita, and the percentage of renewable sources among the total consumed energy.
not good, u must write all the countries in the world because there s no obvious thing that connect most of them...ok some european developed countries and on the other hand some middle east countries. but that s it. u must guess the other just by typing all. nice design anyway:)
According to Wikipedia "About 85 percent of total primary energy supply in Iceland is derived from domestically produced renewable energy sources." Why isn't it on the green list?
