LKramar on 24 Mar 09appears to be a very interesting (freely downloadable) book & website
Supports the ideas of the website www.worldisgreen.com. Readers and anybody else is invited to participate.
Don’t miss this. Blue Planet Run is a book with over 250 awe-inspiring photographs captured by some of the world’s top photojournalists. The idea is to help you know about water problems faced by people in different parts of the globe.
Here are some pictures from the ‘Blue Planet Run’ book:

The advanced industrialized economies were lucky to have had their development fuelled by cheap fossil energy. Today’s developing economies have a much tougher challenge. It was a very short window of opportunity which opened just about 150 years ago and is likely to close in the next 40 years, by when the known reserves will be depleted at current levels of consumption.
All told, 200 years is a very brief interlude considering thousands of years of human civilization and hopefully hundreds of thousands of years yet to come. At some time in the distant future, they will look back and remark that the age of fossil fuel was a short inflection point, a point at which humanity passed through the bottleneck of dependency on oil from the ground. Before that point, humanity’s primary source of energy was the sun, and so it will be after that point.
Today I had a phone call from a Pyrmont blogger who’d discovered PWF’s report on Australia’s first Community Owned Wind Park. His comments?
“Its not everyday, that you read a story on a great community blog, and you go WOW…Why Did It Take So Long…Wake Up Australia…More of the Same Please.”


India's top firms face little stakeholder pressure to combat climate change with only about 40 per cent of the companies surveyed setting voluntary carbon emissions reduction goals, a report said.
A survey by KPMG consultants of 70 CEOs found their response to climate issues was driven largely by the need to comply with expected regulations, while leaving the leadership role in tackling global warming to the government.
While many companies in the developed world have measured their baseline carbon footprint and set reduction targets over 5-10 years, in India only 41 per cent of firms had some qualified reduction goals to be achieved by 2010.
About 38 per cent had no such goals.
Enterprise Rent-A-Car expects a move from PCs to HP thin clients will cut energy consumption by 5 million kilowatt-hours, save about $500,000 annually, and reduce CO2 emissions by 6.5 million pounds per year, Computerworld reports.
The network of more than 45,000 thin client terminals – operated through 743 terminal servers – connects Enterprise rental offices throughout the U.S., Canada, the United Kingdom, Ireland, Germany and Puerto Rico.
Thin clients use only 13.6 watt-hours and 2.4 watt-hours of electricity in active and passive states, respectively, compared with the 77.1 watt-hours and 1.8 watt-hours consumed by PCs.
Rather than wait for Penny Wong, we thought we’d jump the gun with our own Paper on the options for addressing climate change.
The key thing to bear in mind with all this stuff is what we are actually trying to achieve. Yes, yes, we’re trying to do something about the greenhouse effect, but what, specifically, and how? Answering that question properly leads into hotly-contested debates about economic and administrative efficiency, where tiny details can have vast and unforeseen real-world consequences.
