4. Iceland – 7.8 points
      This geologically active country is rich in volcanoes and geysers (A geyser is a hot spring that erupts water in certain intervals). Thanks to geothermal power Iceland gets its electricity and hot water dirt cheap. There have been occasions where steel has been shipped for processing from Australia or Africa and when finished shipped back to the originating country. Cheap local energy actually makes this cost effective. According to the Human Development Index, Iceland (together with Norway) is the world’s most developed country.

冰島 —— 7.8分
      這個(gè)地質(zhì)活躍的GJ有很多火山和間歇泉（間歇泉就是間斷噴發(fā)的溫泉）。由于這些地?zé)釀?dòng)力，冰島的電和熱水特別便宜。很多時(shí)候，鋼鐵從澳洲或非洲運(yùn)到冰島加工，加工完成后再運(yùn)回去。冰島便宜的能量讓這生意非常劃算。

根據(jù)人類發(fā)展指數(shù)，冰島（與挪威）是世界上最發(fā)達(dá)的GJ。
