Earth's Cities from Space

Posted June 03, 2009 9:01 AM

From The Daily Galaxy: Great Discoveries Channel:

Seriously though, if one considers that each of those pin-pricks of light is 1kW, then it's easy to visualise the issue that is becoming labelled, "global warming".

In some parts of the UK, district councils are invoking the turning off of street lights between, say, 0100 and 0500 (or dawn, whichever is earlier) to save energy, and therefore taxpayers' money. From this photo, it's easy to see what all the fuss is about, though some neighbourhoods don't like the idea.

Also: "Hello! Aliens! Coo-ee!"
