Umbra on heating with bathwater

Dear Umbra, After a hot bath, I leave the water in the tub so the heat will go into the room. My husband says the heat saved is inconsequential. How would one calculate the BTUs saved this way? J. ReimanHelena, Mont. Dearest J., I do that too. I’m trying to heat the entire office building […]

Top green-building system is in desperate need of repair

This piece is excerpted from the essay “LEED Is Broken; Let’s Fix It.” The full essay can be found here. Pan of green gables. Once the narrow province of hippies in beads and Birkenstocks, the green-building world has in the last five years blossomed and taken on a professional sheen. That’s thanks in large part […]

Umbra on preparing for winter

Dear Umbra, With the coming winter, our local news did a story on how to save on heating. The tips included window treatments, lowering the water heater, etc. But those of us in apartments are limited in what we can do. I can feel the cold air seeping through the cracks, and laying towels on […]

Umbra on windows

Dear Umbra, I just bought an old house and need to replace some of the windows. Are there alternatives to vinyl windows that will still cut down on heat loss? Noah WinerPhiladelphia, Pa. Dearest Noah, I hope I’ve caught you before you’ve placed your window order, because you are at a moment of opportunity. Window […]

Could TV and film be the key to the renewable energy revolution?

On several occasions I have written about television shows and movies. In doing so, I've tried (albeit unsuccessfully) to start a discussion about the impact they have on audiences when they address environmental issues and/or feature eco-friendly products (hybrids, windmills, etc).

Recently, I issued a call asking (and paraphrasing Bill McKibben): "Where are the movies? The TV shows? The comics? The bleeping video games?"

I believe exposure to such content will help introduce enviro concepts to consumers of pop culture, create awareness (you mean windmills aren't only a Dutch thing?), educate (hey, I didn't realize you could fit two dead bodies in the back of a Toyota Prius!), and start a conversation (do you think Julia Roberts drinks organic soy milk in real life?).

That said, I direct you to a recent piece (based on a true story) by our friend Joel Makower. Our story begins:

(Fade in: two small children running around in a playground. Pan right: A hybrid car slowly drives by while the blades of huge windmills rotate in the background. Narrator's voice begins ... )

If you could pay an extra five or ten bucks a month to help reduce global warming, childhood asthma, rolling brownouts, the national debt, and the threats of Al-Qaeda, would you bother? I'm guessing you'd think that a no-brainer.

So, why aren't you buying clean energy?

The question has been befuddling everyone from environmental activists to utility executives. Nearly every American, it seems, understands that generating electricity from the sun, the wind, the earth's heat, or gases generated by rotting waste is good news for everyone -- the planet, people's health, national security, and the economy.

So, what's the problem? They just don't think clean energy works.

Umbra on washing machines

Dear Umbra, I have a top-loading washing machine that’s nine years old. I’ve heard that front-loading machines are a lot more efficient and use less detergent, so I’m thinking about taking the plunge, even though my old machine works fine. How much less water do the front-loading machines use, and why? And is it true […]

Umbra on clotheslines

Dear Umbra, We would like to install a clothesline this summer to take advantage of the few months of sun that we get here in Oregon. Any advice on the best kind, and how to keep air-dried clothes from feeling like cardboard? German WhitleyPhilomath, Ore. Dearest German, Excellent. If your power supplier is, as I […]

Japanese dress down to save 81 million gallons of oil in summer

What do you do if your country needs to meet targets under the Kyoto global warming protocol? You dress down.

Yup, the Japanese government is encouraging public workers to wear less in order to use less oil. Since many in Japan don dark suits in summer, they crank up the AC to maintain an average temperature of 77 degrees. Someone figured out that Japan could save 81 million gallons of oil in one summer by setting the temperature at 82. To make the warmer workplace more bearable, employees now have the okay to wear short sleeves and go sans tie.

However, one possible unintended consequence of this move is that shirt sales are up. I'm guessing that they are not organic.

Wired reports on the new power generation

We Americans sure do like labels don't we? (And I'm not talking about food labels.) That's right, in addition to soccer moms cruising around town in hybrids and flexitarians buying their food stuffs at Whole Foods and the like, we now have "hygridders."

What's a hygridder? According to a Wired article:

... people who are both middle of the road and off the grid. Across the US some 185,000 households have switched from the local power company to their own homegrown, renewable energy. The fastest-growing segment of this population - their ranks are doubling each year - isn't doing a full Kaczynski. Sure, these folks are slapping solar panels on the roof and erecting the occasional wind turbine, but they're staying connected to the grid, just to be safe. And in many cases, they're operating as mini-utilities, selling excess electricity back to the power company. Just as their cars aren't kludgy and their food isn't flavorless, their homes aren't drafty or dimly lit. Call them hygridders. And look for them soon in a neighborhood near you. Because - trendmeisters, take note - hygrid is the new Prius.

Learn about this new breed by reading the article. And if you feel so inclined, let us know what you think or tell us about your foray into hygridding.
