On-demand water heaters rock

It's totally goofy, but I love my water heater. It's an "on demand" (also called tankless) unit, so it only turns on when I need to do the dishes or wash some clothes, or do both at the same time, even. I like that it doesn't heat a big tank of water 24/7 on the off chance that I'll need it at any moment. Thus it's small, and when it does turn on it's efficient. When not in use, it's completely off. Even though it runs on gas, it has no eternally burning pilot light, and I like that, too. It's three years old now and I've never had any issues with it.

Ubiquitous in Europe and elsewhere, tankless water heaters are gaining popularity in the U.S. too. So if you're in the market for a new water heater and don't have the resources for a solar domestic hot water system, have a look: Rinnai seems to be the best manufacturer. These units save space and resources -- and over time, money.

Environmental Defense’s climate ads go negative, miss the mark

There's no shortage of messaging on climate change these days, but the latest ad I came across concerned me in the same way that Greenpeace's pissy kid ad did. I just heard the radio version of Environmental Defense's two TV ads (which this hard-rock station was repeating back-to-back, for extra negative impact), which tear a page from the same playbook: "The Gift" features kids reading off a list of lousy things that adults are giving them, like droughts, stronger hurricanes, etc. And then there's the one about time running out alongside a long list of bad things to come called "Tick," and one of a girl about to be hit by train thrown in for fun.

Sure, it's the kids whose future will be most impacted, but messaging with fear and guilt is not the way to win the hearts and minds of adults, as Gristmillers discussed here and in many other threads recently. The big green groups really need to get on the positive bus as much as possible, or we're going to see the public ignoring the "threats" of climate change and risk missing the opportunities inherent in getting off of fossil fuels.

Creative use of wind saves cargo vessels fuel

While sailing ships are unlikely to make a comeback anytime soon for oceanic shipping, adding sails to fossil-powered cargo vessels is definitely "on the horizon." This not-new idea is now compatible with the needs of shipping companies, and the savings make both climatic and economic sense:

Coal industry insider tapped to kill Cape Wind

Those trying to stop what would be the nation's first offshore wind farm, Cape Wind, have just hired (another!) coal industry insider to lead the charge. Glenn Wattley is the new director of the Alliance to Protect Nantucket Sound, and as Wendy Williams details in her blog, he's a longtime coal and coal-gasification proponent. She says that this fits with her past reporting: Big Coal is behind many anti-wind efforts.

In a news report on Wattley's new role (rich reading), a spokesman for Cape Wind said that "Wattley is another example of an Alliance CEO connected to coal and oil interests ... Is this really the Alliance to Protect Nantucket Sound or the alliance to protect coal and oil?" I wonder.
