In this video by Ecopolis, the award winning science show on The Science Channel, you’ll meet Valcent Products’ Glen Kertz explaining what part algae biofuel could play in our energy future.

Here are 10 companies that are doing more than talking about turning pond scum into fuel — they are small companies actually doing it. Maybe this is where you should put your retirement savings instead of that dwindling 401K.  (For more on these companies and a peek at five more, see this post from Earth2Tech on 15 algae fuel startups:

Aurora Biofuels
Bionavitas
Blue Marble Energy
GreenFuel Technologies
Inventure Chemical
Live Fuels
Petro Sun

Summer got tired of hearing you can’t be green and stylish at the same time. This model for eco-friendly fashion labels and the host of Discovery Planet’s Green-Jobs show, has written the book on how to do it – from cool purses made out of recycled tires to clothes, makeup, jewelry – all as sustainable as they are fashionable. Oakes doesn’t preach – she says her aim is to be “invisibly green.”

So check out the Invisible Green Activist’s visible results in this video about her excellent new book: Style, Naturally: The savvy shopping guide to sustainable fashion and beauty.

If you have no more room in your closet for any new clothes – no matter how eco-chic – check out Summer’s advice on what to do with your old clothes.

Does this happen to you? Once you start dreaming about exotic places you’d love to escape to – natural wonders of the world where there are no malls or tinsel or shopping lists – you just can’t stop. There are so many things you haven’t done yet in life — like a safari on the Serengeti in Tanzania or swimming with the sea lions in the Galapagos or a trek to the Amazon and Machu Picchu – just puckering up to say Machu Picchu puts me in an adventurous state of mind.

Well, stop dreaming – Natural Habitat Adventures has come to the rescue. This eco-conscious company is offering, not one but FIVE,  big vacations for two – one every year for five years – to the most exciting natural destinations in the world. Beyond those mentioned in my dreams, they’ve also got trips to walk with the penguins in Antarctica and the Falklands as well as a trip to Manitoba to schmooze with the polar bears.

I’ve entered – and so can you – every day up until the deadline, Feb. 28, 2009. Hope to see you there – if not, give the sea lions a smooch for me. Start clicking.

There is probably no single piece of clothing that has ever been as popular –around the world — as blue jeans. What’s not to love – you can dress ‘em up, dress ‘em down. And best of all, they solve that most annoying of all first-thing-in-the-morning questions: “What’s clean enough to wear?”

In the U.S. we more than 500 million pairs of jeans– that means annual sales figures are over $13 billion ($13.4 billion in 2001, the last concrete figures I could find reported).

So just imagine how much we could reduce our collective carbon footprint if each of us handled our favorite fanny-covering in a greener fashion. It’s easy – try these tips:

1. Buy organic jeans from the start.

Ordinary cotton uses a lot of water and chemicals in the treatment process. Check out Levi’s eco-friendly line.

2. Look for hemp jeans:

This versatile plant – and don’t pretend you don’t know what I’m talking about – is ideal for jeans. Fewer pesticides, fewer chemicals, all good.

Check out these sources for hemp jeans: Hempest and Rawganique.

3. Repair your old jeans:

You know those rips look cool anyway. And for those in the wrong places, take out a needle and start stitching. Add your own design while you’re at it.

4. Wash sparingly.

Ok, if the jeans can stand up by themselves, it’s time to scrub. But really, until then, save some water.

5. Recycle the old when you buy the new:

Gained weight? Lost weight? Whatever – there is someone out there who will want the old ones. If they’re in good shape, try a vintage clothing shop. Otherwise, find a Salvation Army near you, or a Goodwill — they’re always ready to do their part in keeping us a little greener.
