Video: Saving Energy around the Water Cooler

Looking for ways to save energy in the workplace? Water coolers/heaters are ubiquitous in offices around the world. Nearly all of them are left on all night long when there’s no point in keeping the hot water hot and the cold water cold. Until recently, your humble Chelsea Green was guilty of this wasteful practice. Well, you know us—we just couldn’t pass up an opportunity to quickly and cheaply green the place up even further. In this video, Jonathan Teller-Elsberg explains how he installed an automatic power timer to save energy and reduce cost. After we’d filmed this segment, a fellow grasshopper pointed out that plug-in automatic timers consume a small amount of electricity themselves—suggesting that we might actually end up with a net loss of energy savings. Well, we wouldn’t want to suggest to our readers they take one step forward and two steps back in the race to reduce carbon emissions. With this in mind, Jonathan used his handy-dandy Kill-A-Watt electricity usage monitor and found that, even with the timer sipping electricity constantly, we still end up with a net energy savings. Here’s Jonathan:
The cooler uses roughly 0.58 kWh of electricity per night (see “Thoughts inspired by the release of our other co-latest Green Guide: Greening Your Office”). So our gross savings using the automatic on/off timer are 0.58 kWh per day. Meanwhile, the timer uses roughly 0.024 kWh per day. That gives us a net savings each day of roughly 0.556 kWh. The financial payback time for the timer is probably something like 4 months. After that, it’s all savings, all the time.
Of course, Jonathan tells me, the financial payback time depends on how much energy the timer is saving you—the bigger the energy hog, the faster the payback time.

Why Modern Wheat Is Making Us Sick

Why is modern wheat making us sick?  That’s the question posed by author Eli Rogosa in her new book Restoring Heritage Grains.Wheat is the most widely grown crop on our planet, yet industrial breeders have transformed this ancient staff of life into a commodity of yield and profit—witness the increase in gluten intolerance and ‘wheat […] Read More

A Dictionary to Survive the Future

When British economist David Fleming died unexpectedly in 2010, he left behind his great unpublished work, a masterpiece more than thirty years in the making—an intellectually evocative and inspiring dictionary, Lean Logic: A Dictionary for the Future and How to Survive It. In it, Fleming examined the consequences of an economy that destroys the very foundations—ecological, […] Read More

Overshoot, Collapse, and Creating a Better Future

In 2016, Earth Overshoot Day happened on August 8—the day when we’ve exhausted the planet’s resources for the year, and are essentially borrowing from future years to maintain our existence today.Perhaps you celebrated this day with a counter-solution: a vegetarian meal, telecommuted, or turned off the air conditioning. There’s a lot more you could be […] Read More

Plants & Pests: Will Bonsall’s Advice on “Wee Beasties” in the Garden

“From a plant’s point of view there is little difference between a cutworm, a woodchuck, a blight spore, and, for that matter, us.”“These are all things that in one way or another prey upon it. It is an inevitable constraint of all living things: We escape one peril only to ultimately succumb to another,” so […] Read More

To Create Climate-Secure Foodscapes, Think Like a Plant

The techniques and prophetic vision for achieving food security in the face of climate change contained in Gary Paul Nabhan’s Growing Food in a Hotter, Drier Land may well need to be implemented across most of North America over the next half-century, and are already applicable in most of the semiarid West, Great Plains, and […] Read More
