300 million pounds of dry-cleaning bags end up in U.S. landfills and waterways annually

However, reusable alternatives to these clear used once plastic bags are becoming popular and adapted by people. Green Garmento reports as much as 60% up-take, which is great, but that’s little more than a half-hearted effort by the general public as there is still 40% to convert. This one is a no brainer without excuses other than your own laziness, people!

There are over 10 billion electrical outlets in North America

Posted by Digital Citizen on Tuesday, June 16, 2009

In this 4 minute talk, John La Grou unveils an ingenious new technology at TED.com that will smarten up the electrical outlets in our homes. He uses microprocessors and RFID tags to do this. The Safeplug invention promises to prevent deadly accidents like house fires and to conserve energy.

This, my friends, could change the face of the electrical outlet that badly needs an update! This is also an example of finding the source of a problem!

John also gives a bunch of impact statistics related to the electrical outlet, like how every year in the US, 2,500 children are admitted to emergency for shock and burn injuries related to electrical receptacles.

The energy impact is amazing, not to mention home damage from fires, can be staggering. Please have a look and judge for yourselves.

Producing 1 kg or 2.2 lbs of veal releases the equivalent of 17 kg (37 lbs) of CO2 into the atmosphere, compared to 16 kg or 35 lbs for beef.

Farting SheepThis data was from a British government-sponsored study, with media reference made by Jonathan Leake in the Sunday Times of London. The reason given for the higher CO2 footprint was that lambs burp (and probably farts to release methane and other greenhouse gases like you, me and the cows) a lot.

Problem was the study was advising to give up lamb roasts to save the planet, not beef. Sure, lamb roasts may be more popular in Britain than in North America, but I highly doubt it is more consumed than beef in either place. If anything, find a way to reduce cow farting and burping, possibly by altering their diets a little. Should be quite possible given you and I both know that if we don’t eat certain things, we don’t fart and burp nearly as much as other things we do eat.

Besides, even if sheep gave off more greenhouse gases than cows, I think most people would agree with me McDonald’s and other beef burgers generally make people fart more than with lamb roast, especially given what else you eat with fast food. We definitely make up for what the cows fart and burp less than the sheep.

Who does those studies and draws those kinds of conclusions???

Mary had a little lamb,
Which burped and farted lots,
Everywhere that Mary went,
She sure smelled like she rots!

If the energy efficiency of the US’ top 10 states could be achieved by the remaining states, 30% of US electricity consumption could be saved, cutting $100 billion in electricity bills, 60% of coal fired electricity, 779 million tons of CO2 to offset the Dutch and UK emissions.

Efficiency was measured by dividing each state‚Äôs Gross Domestic Product (GDP) (total value of all goods and services produced) by the kilowatt hours of electricity it consumed. That’s basically how much money a state could put into the economy for each unit of energy consumed.

Nice stat, but I’d bet if these states made more money per unit of energy, their lifestyle would see more spending and with it, more energy. That would reduce the “efficiency”.

However, the information is still neat to look at how widely states vary for how much they make per unit of energy spent.

New York was at the top with $7.18 for each kilowatt hour of electricity (a 15W compact fluorescent light burning for 66 hours 40 minutes, 66.7 hrs), while Mississippi was at the bottom, by far, at just over $3 per kilowatt hour.

See how other states did in comparison with this really cool interactive map!

There are currently over 18,000 pieces of space junk bigger than 4-inches in size being tracked, with the first satelite fender-bender just occurring to create 500-600 more!

Space… the final frontier… not for exploration but for polluting.

On Tuesday, at about 1700 GMT (12:00 p.m. EST), two satellites collided by accident in orbit about 500 miles (790 km) over Siberia. The collision was foreseen to be likely, but one that was not avoidable because the culprit was a Russian satellite launched in 1993 weighing a ton, believed to be nonfunctioning and out of control. The other was a half-ton (1235 lbs) Iridium commercial satellite, which was launched in 1997.

The immediate space above the Earth has become cluttered enough to allow this sort of thing to happen now, apparently, and it will only become more common in the future. With at least 18,000 pieces of space junk bigger than 4-inches tracked by the U.S. Space Surveillance Network (see photo), all whirling at tens of miles per hour, our immediate space is become a dangerous place to be! Even in the vast expanse that is space, we’ve managed to pollute it so badly it’s becoming a hazard. Where will we go pollute now?

The collision created another 500-600 pieces of debris, by the way. And it should also be noted that not unlike Earth, China is responsible for more than its fair share of pollution. China might not be thought of as a space power yet like the Americans and Russians are and have been over the years, but they’ve got as much junk up there as anybody.

The linked sources below have much more information on space junk, distributions, sources of the junk and so on, if you were interested. There are hopes, I should end with, for systems to help self-remove future space technology as they become dated. The Fast Company link below has some details. It’s a good start to help alleviate this problem before it gets more out of hand. Let’s just hope all the space players think responsibly to do it.
