Saving Water by Conserving Energy

Last week we examined the amount of energy it takes to transport and treat water–and how we can conserve energy by using less water. This week, we’ll look at the inverse of that: how much water it takes to produce energy and how our energy conservation efforts reduce water use.

The water intensity of energy

Whenever water shortages loom anywhere, we hear about how much “embodied water” there is in various products. According to the Water Footprint Network, producing a slice of bread requires 11 gallons of water and producing a pound of beef takes 1,800 gallons. The same sort of analysis can be done with our energy sources. As with foods, different types of energy have different water intensities.

Northwest And Northeast Passages Are Open

Arctic sea ice extent image for August 24, 2010, as compiled by The University of Illinois Cryosphere For the fourth year in a row, and for the fourth time in recorded history, the Northwest passage is completely open. For only the third time, both the Northwest and Northeast passage (north of Russia) are open. If you had a fast enough boat you could race right around the North Pole and Greenland. …Read the full story on TreeHugger

Saving Energy by Conserving Water

It takes a lot of energy to transport and treat water in this country, and it takes a lot of water to produce the energy we use. To put this a different way: when we save water we save energy, and when we save energy we save water.

Most people don’t think about this tight-knit relationship between energy and water, but public officials in a growing number of regions around the country are becoming quite aware of it. This week, I’ll examine how much energy it takes to move water and to treat both supply water and wastewater. Next week, I’ll look at how much water is used in producing our energy.

The energy intensity of water:

The amount of energy needed to deliver clean water and treat that water once we’ve used it varies tremendously by region. If you live in southern California, your drinking water is pumped either from the Colorado River and its assorted reservoirs (including the nation’s largest, Lake Mead, which is now half empty) or from northern California. In either case, that water flows through hundreds-of-miles-long open aqueducts and, via pipelines, up and over mountain ranges.

Friday 5: Turning Over a New Leaf

In just a few short weeks, the kids will head back to school, leaves will begin to change colors, and summer will fade to a blissful memory. Embrace a new season with a little scene change inspired by fall’s most iconic image.

1. Log Bowls from Loyal Loot (pictured above, price not listed)
The juxtaposition of reclaimed wood and bold shades of acrylic paint appeals to our artsy side. An assortment of these in differing sizes and colors arranged on a counter or side table would make an instantly fab focal point.

2. Birch Accent Pillow from Loop Organic ($100)
Available in green or chocolate, this pillow features the beautiful image of a birch branch silhouetted against white organic hemp. The effect is simple, yet supremely stylish.

3. Timber Doormat from Chia’sso ($48)
Made up of sustainable wooden “coins,” this timber doormat creates a Little House on the Prairie meets modern loft vibe. We love how the earthy colors and unpredictable pattern goes with almost any décor.

4. Small Disc Chimes S/4 from PigeonToeCeramics ($28)
Dress up your favorite tree with a set of porcelain windchimes and watch as they gently dance in the breeze. These are available with your choice of cord, but our personal fave is the natural jute twine.

5. Teak Trunks from VivaTerra ($139-275)
Whether you use these teak trunks as stools, end tables, or something else is entirely up to you. However you incorporate these versatile pieces into your space,  they’re sure to add a certain rustic charm.

Any of these pieces speak to you? Which one(s) are on your wish list?

Is Boxed Wine Up to Snuff for Wine Snobs?

It’s leaner (in packaging), greener, and lighter. Shipping it uses fewer resources, so it has a lower carbon footprint. Innovative packaging means the wine lasts longer so there’s less waste. It’s unarguably cheaper than bottled wine (averaging out to less than $10 a bottle). It’s sensibly portable and completely unbreakable – but boxed wine still has an image problem. Is it merited?

While it’s fine for undercapitalized art openings and casual parties and picnics, few serious wine and food folk will choose to pair boxed wine with their finest meals.

I wanted to find out why so I asked a few foodie folks, a winemaker, and a wine store clerk to give me their opinions.

“I’ve never tasted a boxed wine, but a packaging strategy that reduces waste in the food system gets my vote. My feelings are somewhere between neutral and positive, but I’d have to swirl a glug in Riedel glassware or perhaps more appropriately a wide Mason jar to be sure,” said Haven Bourque, Founder HavenBMedia, and contributor to CivilEats.com.

“Wine makers are probably not putting the wines they want to age in boxes. People who really love fine wines and spend good money on cheap wine, green packaging on a nice bottle want the cork, the label, the bottle, the ceremony,” says Dan Glover, Winemaker L’Object Noir Pinot Noir.

“Many of the boxed wines are very drinkable in certain situations. Like a nice fruity zin with a burger or a Sauvignon Blanc at a picnic, but I don’t think that boxed wines will supplant the bottle in the near future. One very good reason beyond image is that some of the world’s finest wines need to be aged. They are alive and change in interesting ways as the years go by. I feel in order to age a wine properly, you need a cork. A real cork. Not a plastic one. This is because it is the tiny amount of air that seeps in through natural cork that ages the wine. This doesn’t happen in a box. Wines in boxes are in a sterile environment. They will last a long time, but they won’t age or change.”

At my local wine store, Paul Marcus Wines, I spied a small selection of boxed wines. I asked the clerk, Ryan VerHey, about the wines and also about how consumers react to them. He told me that usually people are incredulous that the store would recommend boxed wines, but when the employees lead with the green story to convince people to try them, they’ll usually listen.

He starts by telling customers that the packaging is greener, lighter, and lower carbon to ship. He also talks about value and convenience. Most of the wines at Paul Marcus work out to under $10 a bottle. He told me they’re great to keep around if you cook a lot because you can use a little for cooking and a little for the cook. He also mentioned that they are great for camping and for people who bike, because they are lighter. This is something I hadn’t thought of. I’m often pedaling bottles of wine to dinner parties and the thought of lightening my load is quite attractive. I asked if they had to taste a lot of boxed wines before they found some that they liked enough to carry. He told me no, since the distributors know what the store’s buyers like and would only bring the best of the of the box, such as the Pierre Plouzeau Chinon in the 5-liter bag-in-a-box. It works out to be the equivalent of 6-2/3 bottles for $52, or $7.80 per “bottle.”

Want to try a boxed wine? Some of our fellow bloggers have done their homework so there are lots of reviews out there on the web.

Serious Eats took a few for the team, saying most of the boxed wines they tried weren’t so great, but recommending a few drinkable whites and reds.

Meanwhile Epicurious took a few boxed wines on a test drive and came up with four reds and one white they could live with.

Some of the packaging is more green than others and some of the wines are organic, further enhancing their green cred. The Daily Green chose 8 green boxed wines and recommended dishes to pair with them. The wines reviewed on The Daily Green feature some of the most innovative, green packaging. I’m intrigued by the Yellow + Blue certified organic wine, because it was one of the ones my great wine store was carrying, and it’s organic.

Slashfood chose 7 boxed wines to review and were pleasantly surprised by the quality of many.

Ehow reviewed 5 wines, noting their tasting characteristics, if not their greenness.

A few wines show up over and over in the various reviews. Does that mean they are the best? Or are they just the most available? I guess I have some drinking and find out.

The most commonly mentioned wines in all of the reviews were Black Box Wines, Three Thieves, and French Rabbit wines.
