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]

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]
