Time is Running Out: Get Up To $2,000 from Cambridge for Installing Solar Hot Water

Through November, Cambridge Energy Alliance is offering Cambridge businesses and residents up to $2000 to install solar hot water heaters. The CEA Solar Hot Water Grant combined with the state and federal incentives, will allow you to install a new 20-year hot water heating system for up to 75% off. Average systems that are normally about $8,000 will cost less than $2000 in out-of-pocket costs.

Cambridge resident Ken Bader installed a solar hot water system a few weeks ago, saying “the grants and tax credits made this deal a no-brainer! I’m looking forward to paying (almost) nothing to heat my water.” Since his solar system allowed him to eliminate his hot water heating tank entirely he’s looking forward to the added benefit of “not having to buy a new water heater … [view entry]

NSTAR has approved an extension to the Early Boiler Replacement Rebate Pilot

Have you been thinking of replacing your 30+ year old boiler?

Now, only through the end of September 2012, the Mass Save® Home Energy Services Program is providing a temporary increased rebate for replacing 30+ year old boilers.  The rebate ranges from $1,750 to $4,000 for new efficient boilers using the same fuel and installed by October 31, 2012.  This is a large increase from the normal $400 to $1,500 in existing rebates.  A no-cost Mass Save home energy assessment is required by September 30, 2012 to determine if your boiler qualifies.

Not sure what a boiler is or if you have one?

Schedule your no-cost Mass Save home energy assessment and your home energy advisor will let you know if you have a boiler and he/she will also collect the information … [view entry]

Search for the Solar Grail

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


Part 1

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

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

Whitehouse Goes Solar!

Under mounting pressure from 10-10-10 groups,’s Bill McKibben, and various other environmental activists, the Obama Administration announced today that it will re-install solar panels on the White House roof. After weeks of rallying support for the Solar Road Trip including over 40,000 signatures by citizens who urged the President to retrofit the White House, Bill McKibben,, Unity College students, and the 40,000+ who were following the event were ultimately disappointed; previous coverage. The White House refused to take the Carter-era solar panel which was removed when Regan took office, and has since been living in Maine. however, the administration promised that they would “continue deliberative processes” surrounding solar on their roof. Since that day, not much has been mentioned on this topic by McKibben, other than that … [view entry]

Solar-powered sailboat on display in Shanghai

Suntech boatAs the World Expo in Shanghai enters its second month, the company Suntech Power delivered an extra attraction at the Chinese display: a solar-powered sailboat. The 10o foot long catamaran was unveiled on the Huangpu River yesterday, in a ceremony attended by Communist Central Committee Secretary of Shanghai, Mr. Mr. Zhengsheng Yu, as well as representatives from Suntech. Both the party leader and the CEO of Suntech voiced the need for continued expansion of solar energy as an indispensable part of the Chinese energy production.  “To meet the soaring global demand for Suntech’s solar products, we plan to add 1,000MW of crystalline silicon cell and module production capacity at our Shanghai facility within the next three years,” said Dr. Zhengrong Shi, Suntech’s Founder, Chairman, and CEO.” In addition to the boat, known … [view entry]

Cambridge Solar Power, by the Numbers

solar homeThe city of Cambridge is home to 33 solar electric (PV) systems that provide 267 kilowatts of clean, renewable energy generating capacity. Assuming ideal conditions of 12 hours of cloudless bright sunlight per day, they could generate 1.2 megawatt-hours (MWh) of electricity per year. A little less than what a typical wind turbine is capable of producing in an hour. Of course, this is a hypothetical maximum.

There’s no way that Cambridge’s 267 KW of PV could generate 1.2 MWh/yr of electricity because the sun don’t always shine! Especially here in New England… but if we assume the sun shines for an average of 3 hours each day, the existing PV installations would produce 292 MkWh of electricity per year. This is still a substantial amount of power. The Energy [view entry]

Can the solar power-assist prototype for buses be a sustainable solution?

The Californian Sunpods Inc manufacturing company produces innovative, modular and tested solar power stations. One of their latest projects, is to build the first solar power-assist for buses. This system will help Bauer Intelligent Transportation meet strict anti-pollution standards laid down by the State of California. Diesel vehicles are not allowed to remain idle for more than five minutes after the passage of  the California Anti-Idling law in 2008. California joined 17 other states in passing anti-idling legislation.

Sunpods Inc ‘s solar power-assist system is made up of four solar panels which are fixed on the roof of the bus. They can charge an on-board battery bank to power the air-conditioning and wireless connectivity equipment when the bus is inactive. Tested on a Bauer Intelligent Transportation bus since January 2010, this solar … [view entry]

China Leads U.S. in clean energy investment

Rape Flowers & Wind Power Plant ,  Jeju Island, KOREA by daejeonThe recent report of The Pew Charitable Trust shows that for the first time China is spending nearly doubled in clean energy  investments compared to the United States. In 2009, China invested $34.6 billion in wind power, solar energy and other forms of renewable energy, whereas United States only invested $18.6 billion dollars. The United States lagged behind 10 G20 members in percentage of gross domestic products. The report explains that Spain invested five times more than the United States last year, and China and the United Kingdom three times more.

Phyllis Cuttino, who directs the Pew Environment Group’s Global Warming Campaign explained that, “Having built a strong manufacturing base and export markets, China is working now to meet domestic demand by installing substantial new clean energy-generating capacity to meet ambitious renewable … [view entry]
