TOP 10 – COUNTRIES LEADING IN CLEAN ENERGY

ENERGY CONSUMPTION PER GDP( KWH /$): 0.51 KWH / US $ RENEWABLES SHARE: 27.7 % ALTERNATIVE AND NUCLEAR SHARE: 45 % CLEAN ENERGY INDEX: 73.6 / 100

Switzerland is the most energy-efficient country in this entire ranking, requiring just 0.51 kWh to produce a single US dollar of economic output. That is a figure that leaves every other nation in the top 10 trailing. As an extremely mountainous country, hydroelectric power has long been a cornerstone of its energy mix, providing nearly 56 % of all its electricity. That, combined with nuclear and a carbon intensity of just 30 gCO₂ / kWh, has helped Switzerland show that efficiency and cleanliness can go hand in hand.
