Rather than watching another annoying episode of “Lost”…

You may have heard that John Doerr, investor extrodinaire, recently gave an emotional presentation at the TED conference where, talking about global climate change, he said that “I’m scared. I don’t think we’re gonna make it.”

Although the TED website doesn’t have that video on yet, I did find a great episode of Charlie Rose where he talks with John Doerr, Scott McNealy and K.R. Sridhar about alternative energies.

I also found a follow up presentation from last year’s TED by none other than Al Gore. Watch it here

As Tim Gunn would say, “Make it work!”

Austin Scarlett's DressAre you a fan of the TV show, Project Runway? If you are a reality show junkie, chances are yes. So, do you remember in Season 1, the designers were challenged to go to the grocery store, pick up a few items and “make it work”? The winner of that challenge, Austin Scarlett, made a dress from corn husks, which was particularly innovative, and didn’t look half bad as it walked down the runway.

Anyway, it turns out researchers at the University of Nebraska - Lincoln are fabricating (haha, get it? fabricating?) new ways to make textile fibers from agricultural waste. Things like rice gluten, wheat straw and chicken feathers are being considered as the new alternatives to petroleum fibers.

According to this article, “petroleum-based nylons and polyesters make up 60 percent of the world’s textile fiber consumption. Producing such fabrics takes lots of energy and emits lots of greenhouse gases.”

OK, so it looks like there’s some interest in finding alternatives to petroleum fibers, which I wholeheartedly support. But are designers really using these alternatives?

Well, it turns out they are starting to. According to Time Magazine, things like bamboo, coconuts, corn, soy, and of course, hemp, are in stores today. Personally, I haven’t seen anything other than hemp, so I would be curious to know how these other products fare. Reader, leave a comment and let us know if you’ve come across any of these new alternative fabrics and where!

Al Gore for President (and other musings)

Today I read an article explaining that according to NASA scientists, “due to global warming, glaciers on Greenland are slipping into the ocean twice as fast as they were just five years ago.” It’s not hard to find evidence both anectotal and empirical that global warming is happening, and this is just one example. As the panda in my sister Ann’s favorite joke would say, “look it up.”

But what to do? Those of us who know about the problem can do what we can (which is why we started this humble blog), but uncoordinated action of a few people won’t be enough. After all, as we sit here we counting recyclables and installing a few fluorescent bulbs, Dick Cheney is pushing drilling for more oil in Alaska, Greenland is melting and the ocean is rising.

It is often said that “in democracy you get the leadership you deserve.” Therefore, I think it should be part of anyone’s Global Warming Action Plan to make sure that we elect leaders who are committed to the environment, and whose actions back up their promises. One thing we can all do is to write to our elected officials and let them know that we will hold them accountable if they don’t act. (in the US, you can find your elected officials here) We can also make ourselves heard with other political action. I must admit I’m still learning about all the things we can do, but stopglobalwarming.org seems like a good place to start. We’ll be posting more on this later.

But the reality is that global problems like this need global solutions, and global solutions require strong leadership. Which brings me to Al Gore. Since the 2000 election, it’s become increasingly clear that Al Gore has been right about the right things, long before others have been. As the San Jose Mercury News points out in this editorial, “on the issues that most Americans … care about - the war, the fragile state of the Earth, the transforming power of technology - Gore has been out front, resolute and right.”

But this is an enviornmental blog, and on the enviornment, Gore has been a strong visionary leader on global warming, from the time George Bush senior (who should be embarrased now) called him “ozone man,” to now, where Al Gore has almost singlehandedly brought global warming to the forefront of the public consciousness. Electing Al Gore would be a strong signal to the country and to the rest of the world that we are serious about this issue.

So in summary, dear readers, don’t forget to include political action. And maybe if your political action includes contacting Al Gore, he’ll hear us. To quote the Merc, “bide your time, Al Gore, as Bobby Kennedy did in ‘68. The campaign is too long as it is. But don’t waver when the moment comes.”

Ahem. Were you going to recycle that can?

One easy thing that everyone can do to reduce greenhouse gases is to recycle. Why? Well, according to Henry Ferland of the EPA circa 2000, “Waste diversion, through source reduction and recycling, can reduce GHG emissions in two ways: 1) Emissions associated with waste disposal, particularly landfill methane emissions are avoided; 2) Emissions associated with resource extraction are also avoided.” (source)

Not convinced? How about some stats then? According to the Stanford Recycling Center:

Aluminum Recycling of aluminum cans saves 95% of the energy required to make the same amount of aluminum from its virgin source. One ton of recycled aluminum saves 14,000 kilowatt hours (Kwh) of energy, 40 barrels of oil, 238 million Btu’s of energy, and 10 cubic yards of landfill space.

Newsprint One ton of recycled newsprint saves 601 Kwh of energy, 1.7 barrels of oil (71 gallons), 10.2 million Btu’s of energy, 60 pounds of air pollutants from being released, 7,000 gallons of water, and 4.6 cubic yards of landfill space.


Office Paper
One ton of recycled office paper saves 4,100 Kwh of energy, 9 barrels of oil, 54 million Btu’s of energy, 60 pounds of air pollutants from being released, 7,000 gallons of water, and 3.3 cubic yards of landfill space.

Plastic One ton of recycled plastic saves 5,774 Kwh of energy, 16.3 barrels of oil, 98 million Btu’s of energy, and 30 cubic yards of landfill space.

Steel One ton of recycled steel saves 642 Kwh of energy, 1.8 barrels of oil, 10.9 million Btu’s of energy, and 4 cubic yards of landfill space.

Glass One ton of recycled glass saves 42 Kwh of energy, 0.12 barrels of oil (5 gallons), 714,000 Btu’s of energy, 7.5 pounds of air pollutants from being released, and 2 cubic yards of landfill space. Over 30% of the raw material used in glass production now comes from recycled glass.

So next time you are thinking of just tossing that can in the garbage because there’s no recycling nearby, think of the children (they are our future), and recycle!

I’m going to set a goal for myself of no beverage containers thrown away for a month. Let’s see if it works.

I am not easily LED.

So I recently read that the State of California, where I live, wants to be the first state to ban incandescent lightbulbs by 2012. They propose moving towards the use of CFLs, or compact flourescent lightbulbs.

While I applaud energy-saving measures, I wonder about CFLs. On the one hand, they are supposed to offer energy savings of 75-80%, compared to the traditional incandescent light bulb, and last longer (6-10 years). However, I’ve never particularly cared for flourescent lighting, and I’ve heard that CFLs have mercury, which makes disposal somewhat problematic. What other options do we have?

LEDs, or Light Emitting Diodes, are a plausible choice. I admit that I’m no lighting expert, but from what I’ve read so far, they seem to have great potential. The things that I like about LEDs: greater efficiency (80% compared to 20% for incandescents); long life span (~100K hours!); low environmental impact (less energy is required to manufacture); durability (they aren’t as breakable as incandescents); no noise (unlike flourescents, they don’t “buzz”). The cons: in the short term, LEDs are more expensive than incandescents and flourescents; installation can be expensive; and LED technology is still evolving - therefore it maybe worth revisiting in a few years.

Here’s a great chart I found which compares the various options that are out there today and the pros and cons of each.

In the meantime, have any of you experienced LED technology firsthand? What are your thoughts?
