Riverside Lightbulb Exchange saves 66 tons of CO2 emissions!

Riverside Bulb Exchange Volunteers This past Sunday, August 9th, 24 Community members traveled door to door in the Riverside neighborhood of Cambridge distributing free energy efficient compact fluorescent light (CFL) bulbs and efficiency resources to hundreds of homes. These volunteers exchanged a total of Four hundred and forty-two CFL bulbs over the course of four hours, the equivalent of saving 132,000 pounds of carbon dioxide emissions from being emitted into the atmosphere per year. A great Success!

This community event, organized by the Cambridge Energy Alliance (CEA) and the Home Energy Efficiency Team (HEET) , was held in order to help residents lower their home energy consumption and cut carbon emissions in Cambridge. The HEET organization regularly participates in community barn raising events to help Cambridge residents lower their carbon footprint by implementing efficiency measures in homes with support from volunteers and this Riverside light bulb exchange is a continuation of CEA’s summer canvass program, connecting Cambridge residents to efficiency programs and services. The benefits of this light bulb exchange will stretch further than helping to save the earth- it will help residents save money on their energy bills as well! If a resident were to exchange 20 light bulbs in their home it would save approximately $1,200 dollars over the life span of the bulbs.

The event would not have been possible without the generous donation of the CFL bulbs by TCP, Inc. Metro Pedal Power , a local company that provides delivery services using human powered vehicles, provided for the carbon-free delivery for the CFLs to the Cambridge Community Center, making the light bulb exchange a completely carbon free event! And of course, the event’s success is owed to all of the Cambridge volunteers as well, who donated their time on an extremely hot Sunday to help their neighbors. Volunteers ranged all different ages and canvassing experience levels, and after the canvass, a community party was held at the Cambridge Community Center where they celebrated their outreach efforts together. Among the volunteers were Leland Cheung , and Minka vanBeuzekom , both of whom will be running for Cambridge City Council this coming Fall.

Retrofitting Halogen Track Lighting with LEDs? Someday soon, we hope.

With energy savings of up to 80% over Halogen, retrofitting your MR16 track lighting with LEDs would seem to be a no-brainer. The problem is, well, it’s complicated. The prices on this type of lighting are falling fast, and the bottom line is; making a big investment now might not make sense.

LED tracklight

According to Wikipedia, there are few standards for MR16 and MR11 compatible LED lamps, and with a large variety of designs varying significantly in beam control, light quality, efficiency and luminous power, getting the right light for your model of track lighting may be difficult. Or impossible. Most LEDs run on DC current; halogens most often run on 12 volt AC current. So your bulb will need to have an integrated rectifier.

If this is all greek to you, it’s probably not the greatest idea to tackle this solo.

Think twice before placing a huge wholesale order from the Pacific Rim. With reputable sources selling dimmable LED halogen replacements for 30-70 dollars a bulb, you have to wonder about the longevity of a 10 or 15 dollar generic knock-off.

In the pioneering spirit of Warm Home Cool Planet, we appointed ourselves guinea pig and ordered fifty bucks worth of the, ah… affordable bulbs to test in one of our living rooms. We’ll keep you posted on the results.

We’re looking forward to these bulbs hitting the mainstream residential market in the next few years. Stay tuned to this channel.

Wireless Electricity is Green

Wireless Electricity (or the concept) has been around since 1890 when Nicholas Tesla built a 200 ft, 100,000 watt tower that sent 130 ft bolts into the sky and turned the grass blue. Now, thanks to MIT Asst. Professor and 2008 MacArthur Genius Grant Winner, Marin Soljacic, wireless electricity is close to reality. And it’s greener than you think:

But wireless technology is not only neater (say good-bye to the power-strip Medusa under your office desk), it’s cleaner. The EPA says Americans purchase a total of 3 billion disposable dry-cell batteries every year (part of a worldwide market of about 15 billion) and then throw 2.8 billion of them into landfills. Wireless systems are designed for rechargeable batteries that can be reused hundreds of times before they become trash. Continue reading
