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.

India's overall installed capacity has reached 329.4 GW, with Renewables accounting for 57.472 GW.

Significant rise on the data released by the ministry in February when the figure stood at around 50 GW.

In the country's renewable mix, wind power accounted for 56.2 percent with as much as 32.3 GW, followed by solar which took the share of 21.8 percent with 12.5 GW
In April 2017, solar reached 3.8 percent of total installed capacity up from 2.23 percent in April 2016.

Country's coal-fired fleet remains strong with a 59 percent share in the total energy mix, although National Thermal Power Corporation (NTPC) has showed itself to be the principle supporter of the government's green energy agenda.

India has set a target of reaching 170 GW of renewable energy capacity by 2022, out of which 100 GW is to come from solar

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.

Electric-power transmission

is the bulk transfer of electrical energy , from generating power plants to electrical substations located near demand centers. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution . Transmission lines, when interconnected with each other, become
transmission networks. The combined transmission and distribution network is known
as the " power grid " in the United States , or just
"the grid". In the United Kingdom , the network is
known as the "National Grid
