10 Most Energy-Efficient Countries

1. Germany

When speaking of Germany, it is not uncommon to hear the phrase “German efficiency.” Therefore, it is not surprising to find Germany on top of this list. According to a recent study put out by the American Council For An Energy Efficient Economy, Germany was the best country overall for energy efficiency, scoring high in multiple categories for a total score of 65 points out of 100 on their study.

2. Ireland

While Ireland’s economy is based mostly on the service and IT sectors, the Land Of The Leprechaun did come in as sufficiently green. Ireland has reduced its carbon emission by 15% per year for the last several years.

3. Denmark

Denmark has a population about half the size of New York City, but, even still, its energy usage is remarkably low. Each Dane consumes about half as much energy as each American, and that does not have to do with the difference between alternating current and direct current.

4. United Kingdom

The United Kingdom recently vowed to cut carbon emissions by a whopping 80% before the year 2050. And, in addition, the country’s main business, its financial sector, uses very little energy anyway.

5. Norway

Norway derives almost all of its energy from sustainably green hydroelectric damns and would be much higher on this list if not for its incredibly high per capita consumption of energy, which my be caused by its cold climate.

6. France

Forward-thinking France does much to encourage energy efficiency within its borders. Besides offering major tax credits for energy efficient businesses, the industrial and transport sectors of the French economy have increased their efficiency by 19% and 12% respectively.

7. Austria

Austria does a lot to ensure that it is relatively energy-efficient. About 23% of its energy reserves come from renewable sources, an astonishingly high figure.

8. Italy

Italy made it on this list by scoring very high on the energy efficient aspects of its transportation industry. However, Italy’s industrial sector has lost major ground in energy efficiency, suffering a drop of nearly 25% recently, which accounts for their relatively low ranking.

9. Mexico

Although it is by no means a leader in green initiatives, Mexico’s young economy has shown much promise in increasing its energy efficiency. Many large initiatives are being undertaken to make Mexico among the most energy-efficient countries. As Mexico continues to grow, it is likely they will move up these rankings.

10. Australia

The Land Down Under makes it onto this list, but just barely. Although Australia has made considerable strides in ensuring energy efficiency in its building construction, its transportation is a major cause of pollution. Couple that with a recent repeal of a carbon tax. and Australia is actually sliding downward.

Electrical Blackout
INDIA — JULY 30-31, 2012

In the largest electrical outage in history (so far), the July 31st blackout of India affected an area encompassing about 670 million people, which is around 9% of the world’s population. On the 31st, three of the country’s interconnected northern power grids collapsed for several hours, affecting 22 states from the country's Eastern border with Myanmar to its western border with Pakistan.

Citizens of Delhi dealt with 89% humidity and, in West Bengal, hundreds of miners were trapped underground for hours after their lifts broke down. In the most disturbing and vivid detail, The Guardian reported that electric crematoriums stopped operating, some with bodies left half burnt before wood was brought in to stoke the furnaces. Overloading and human error were eventually blamed for the troubles.
