Look at India.(image)

Now we know why we have Power-cuts!

This image of Earth’s city lights was created with data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS). Originally designed to view clouds by moonlight, the OLS is also used to map the locations of permanent lights on the Earth’s surface.

The brightest areas of the Earth are the most urbanized, but not necessarily the most populated. (Compare western Europe with China and India.) Cities tend to grow along coastlines and transportation networks. Even without the underlying map, the outlines of many continents would still be visible. The United States interstate highway system appears as a lattice connecting the brighter dots of city centers. In Russia, the Trans-Siberian railroad is a thin line stretching from Moscow through the center of Asia to Vladivostok. The Nile River, from the Aswan Dam to the Mediterranean Sea, is another bright thread through an otherwise dark region.

Even more than 100 years after the invention of the electric light, some regions remain thinly populated and unlit. Antarctica is entirely dark. The interior jungles of Africa and South America are mostly dark, but lights are beginning to appear there. Deserts in Africa, Arabia, Australia, Mongolia, and the United States are poorly lit as well (except along the coast), along with the boreal forests of Canada and Russia, and the great mountains of the Himalaya.

The Earth Observatory article Bright Lights, Big City describes how NASA scientists use city light data to map urbanization.

How The West Squanders Light and Energy Satellite Proof.

In Environment on July 9, 2012 at 20:43

The proof is here as to who guzzle energy and contribute to Global Pollution.

Irony is that these countries and the EU are taxing the countries like India under the guise of carbon Tax!

India is pondering to hit back.

Hope it does.

Waste of Energy

Britain and Europe at Night.

 

Waste of Energy

Light show: An image of the U.S. from space highlighting the staggering light pollution, especially on the east coast, in Houston, Texas, and San Francisco and Los Angeles on the west coast

Africa in Darkness,

In darkness: Third World countries in Africa barely register any light at night in contrast to the West, apart from an amazing trail of light from Cairo running down the Nile in Egypt

World at Night.

Global view: A satellite picture of the energy waste in the West and darkness in the rest of world showing how much more energy the rich world uses than other areas

 

At night, London is a burning bright spot, consuming enough energy to power Ireland with its light show.

But as these stunning images from space show, we in the West are guilty of wasting energy and polluting light on a staggering scale.

Now compare the Third World countries in Africa, South America and large swathes of Asia which lie in almost complete darkness

Each year London consumes 150 thousand gigawatt hours of energy, equal to the consumption of nations such as Portugal and Greece.

Campaigners have warned that 50 per cent of the UK’s population cannot see many stars because the night skies are ‘saturated’ with light pollution.

The pictures created by scientist Felix Pharand-DeschÍnes using data gathered by satellites highlight the contrast between the first and third world.

They show Egypt’s densely populated River Nile as it scorches a path through the darkness of Northern Africa while Japan is wall-to-wall light.

America shines brightly, but south of its border the countries are almost lightless and in central Asia, India and Australia barely any light is registered.
