Reminder: Light Bulb Swap on Saturday!

this-and-this

If you are a Cambridge resident, this is a reminder to come swap up to three of your incandescent or CFL light bulbs* for free LED replacements this Saturday, Dec. 10, at the Cambridge Winter Farmer’s Market at 5 Callender St, from 10am-2pm! We will also have a pop-up store with heavily discounted LEDs for all of your other lighting needs.

*The swap is limited to A19 and BR30 bulbs.

This event is part of the City’s 100% LED Campaign that encourages residents to change over their lighting to LEDs, which use six times less energy. Please note that the bulb swap is limited to Cambridge residents and while supplies last.

City Offers Limited-Time Incentives to Go 100% LED!

It’s about to get a whole lot easier to upgrade your lights and save money and energy! The City’s Cambridge Energy Alliance is partnering with Eversource to launch the “100% LED Cambridge” campaign, which offers limited-time specials on LED light bulbs for Cambridge residents. The campaign encourages residents to upgrade 100% of their home lighting to LEDs, which use six times less energy than older bulbs.

Money Saving Light Bulbs

During the summer of 2014 several high school students interned at the Cambridge Energy Alliance helping with canvassing and outreach across Cambridge. The interns also wrote a few blogs on topics they were interested in related to energy efficiency and solar power. The following is one of their blogs.  

 

Today, unfortunately, money is on the minds of many people. This blog offers a simple and straightforward strategy to save money, and energy, by using different types of light bulbs. Currently in the US most people use incandescent light bulbs in their households. However, slowly the tide has turned to Compact Fluorescent Lamps (CFLs) bulbs, which offer greater service and economic satisfaction. But what is it that makes these light bulbs so different? Of course they all have differences in their structure, … [view entry]

Japan and Cambridge Target Renewable Energy

During the summer of 2014 several high school students interned at the Cambridge Energy Alliance helping with canvassing and outreach across Cambridge. The interns also wrote a few blogs on topics they were interested in related to energy efficiency and solar power. The following is one of their blogs.  

 

Renewable energy and energy efficiency may be a common topic in Cambridge, but there is still much we can learn from around the world.

In Japan, energy efficiency policies have been administered under the Energy Conservation Law since 1979, which forces manufacturers to increase the energy efficiency of their products. However, energy efficiency and renewable energy has become more essential in Japan today.

After the Tohoku earthquake and tsunami, which took place in Fukushima Daiichi in March 2011, Japan reconsidered its energy … [view entry]

Solar Panels in Cold Climates

During the summer of 2014 several high school students interned at the Cambridge Energy Alliance helping with canvassing and outreach across Cambridge. The interns also wrote a few blogs on topics they were interested in related to energy efficiency and solar power. The following is one of their blogs.  

 

Think about this: as of now, Germany is the world leader in solar energy. It uses more solar power than any other country in the world. Now think about this: Germany is equal to Alaska in solar resources. If Germany is a good place for solar paneling, then Cambridge must be too! But can cold climate places really sustain solar paneling?

What most people don’t know is that solar panels run off of light, not heat. Many panels have the ability … [view entry]

Solar Co-ops: Another Way to Go Solar

On Earth Day, the Rocky Mountain Insitute  reminded us of an effective tool for solar development: the solar co-operative. Like any co-operative, solar co-ops pool the resources of many in order to increase purchasing power, increase access to benefits, and create other efficiencies. Businesses and/or individual consumers band together to collectively purchase solar photovoltaic (PV) panels and share knowledge about best practices. Here are a few kinds of solar co-operatives that are relevant to Cambridge residents.

Community Solar

One type of co-operative concept called community solar can help bring solar to those who typically wouldn’t have access to it, such as renters or any households without enough rooftop sun exposure. Community solar allows customers to buy into an off-site system and receive credits on their utility bills. Customers can purchase as … [view entry]

Energy Efficient Lighting Upgrades for City Buildings

The City has taken another exciting step toward reducing energy use by performing lighting upgrades at the Coffon Building, Engine 8 (Taylor Square), Fire Headquarters and three buildings at the Cambridge Cemetery. Existing lights within these facilities have been replaced with high-efficiency lamps and fixtures, and occupancy sensors have been installed in many locations throughout the buildings in order to reduce energy use and costs even further. Projected energy savings from these lighting efficiency upgrades is an estimated 130,000 kilowatt hours/year, resulting in avoided costs of approximately $18,000/year for the City. These energy savings represent averting close to 200,000 pounds of carbon dioxide emissions into the atmosphere annually, the equivalent of removing 18 cars from the road!

The electric use of these buildings will continue to be monitored as part of the … [view entry]

2011 Intern Dana Rubin to Travel the U.S. in Search of Practical Environmentalism

2011 summer intern Dana Rubin will be traveling around the country starting on September 1st, 2012 to seek out the practical and economical environmental projects that are occurring all across the nation.

Dana, and her partner-in-crime Hannah Blackmer, want to take the fear out of climate change and make it a more positive transition. There are so many projects that individuals and small businesses can conveniently do to build up a better resilience to save money and help the environment.  Their voyage is The Search for Convenient Resilience and they will be seeking out projects that range from homesteading, rooftop gardens, personal alternative energies and upcycling projects.

Dana and Hannah, recent graduates of Mount Holyoke College, really need your help to raise enough funding to make the endeavor possible. The … [view entry]

Search for the Solar Grail

This is a guest post from Eric Grunebaum from the great blog, EnergySage.

Search for the Solar Grail

Hello to new EnergySagers –

I’m located in Massachusetts and I thought my recent experiences looking into solar PV for my house might be helpful for folks.

First off, I should say that I’m pretty lucky to have an unobstructed south-facing roof. I’ve been thinking about solar for a while, and watching prices go down, so a couple of months ago I started asking people who had installed solar PV panels if they could recommend companies. I found two through word of mouth and then I found three more via EnergySage.com.

I was definitely interested in the “social” benefits of cutting back on fossil-fuel generated electricity, but what really … [view entry]

Cities Lead the Way

Last night, I attended a meeting hosted by SF Environment, a department of the city and county of San Francisco.  I was in awe and inspired by how much one city can accomplish when it comes to educating the public about energy efficiency and environmental consciousness.  Not only is San Francisco leading the domestic urban composting charge with a city-wide composting program, whereby the city mandates composting in addition to recycling, but the city is making the process of being an ecoconsumer easier and easier.

When I relocated here two months ago, I was astounded at how commonplace composting was – the city simply places compost bins throughout the city and provides them to each city resident.  In addition, SF Environment provides free compost containers for your kitchen so you can … [view entry]
