TOP 10 – COUNTRIES LEADING IN CLEAN ENERGY

ENERGY CONSUMPTION PER GDP( KWH /$): 3.98 KWH / US $ RENEWABLES SHARE: 82.4 % ALTERNATIVE AND NUCLEAR SHARE: 89.3 % CLEAN ENERGY INDEX: 86.8 / 100 Iceland’ s geology has contributed significantly to its position as a clean energy leader. The island of Iceland straddles the Mid-Atlantic Ridge, right where two tectonic plates pull apart. As such, volcanic heat is constantly being pushed towards the surface of this ridge. This natural quirk is the phenomenon behind not only the hot springs that tourists so enjoy, but to the geothermal heat that has anchored the Icelandic energy mix for years.

This, combined with the glacial rivers that power its hydroelectric stations, gives Iceland an electricity grid unlike anything else on the planet. Its carbon intensity of just 28 gCO₂ / kWh is the lowest of any country measured, three times

cleaner than Austria and fully 12 times below Germany’ s figure.

A staggering 82.4 % of all energy consumed in Iceland comes from renewable sources, and fossil fuels account for barely a tenth of the country’ s electricity. Iceland is, by almost every measure, the cleanest grid in the world, and is a living proof of what becomes possible when a country is willing to build its entire economy around the energy beneath it.
