Solar Co-ops: Another Way to Go Solar

Posted on by

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 much or as little solar energy as they want, and they don’t have to worry about installation or maintenance.  The Clean Energy Collective  was one of the first organizations to establish this model and they now operate multiple solar gardens throughout the US.

Residential Solar Co-op

The Mt. Pleasant Solar Cooperative offers another model for co-operative solar, as the Washington, D.C. area neighborhood group has organized over 300 households in order to purchase solar PV panels in bulk. This has reduced installation costs for households getting PV panels and has ultimately brought more solar power into the community than would have otherwise been the case. In addition to increasing the affordability of solar, the co-op network fostered a supportive atmosphere that diminished other barriers to solar energy. Says Mt. Pleasant solar system owner Louise Meyer: “I felt like I was part of a team, it made much more sense, you could compare notes and not feel so stranded. It was such a new area for many people, and the paperwork is such a hassle, being part of the cooperative made it so much easier.”

The Mt. Pleasant model has spurred the creation of other neighborhood solar co-ops in the region as well. Several of the neighborhood groups are further organized under the umbrella organization DC SUN, which advocates for solar energy and serves as a regional resource for anyone interested in solar.

Conclusion

The solar co-op model is a promising tool to increase solar energy development in a range of contexts. With its variety of housing types and large multifamily housing stock, we see co-operative solar as a viable solution for Cambridge. What do you think? Would one of these models work for you?

Across the country, the demand for energy is rising rapidly.  Yet, despite known negative implications for our environment, we still allow more than half of the total energy produced in the U.S. to go wasted due to inefficiencies. [1]

The City of Cambridge wants to help change this, and as part of our commitment to environmental sustainability, energy efficiency, and climate change action, we have pledged our intent to compete in the $5 million Georgetown University Energy Prize.

The Prize kicked off at a two-day conference in Washington, D.C. on April 23, 2014. At the event—which officially opened the competition’s Application Phase— The City of Cambridge was announced as one of more than 50 communities who have signed letters of intent to compete for the Prize. Meghan Shaw, the Community Outreach Director for the Cambridge Energy Alliance, attended the launch of the competition—there she is in the Indian Treaty Room of the White House, fifth from left in the middle row, with other competitors:

GEUPlarger

As a competing community, we join other small- to medium-size towns, cities, and counties that will develop and implement creative, sustainable, and replicable strategies to save energy. Here’s a map of the other communities that have also pledged to compete:

guep map

During the current Application Phase, we will work collaboratively with local stakeholders to develop an energy-saving plan that will not only deliver financial benefits to residents, but will also help ensure the long-term sustainability of our community. Most importantly, we aim to design a plan that other communities can replicate—so that we can all do our part to increase our nation’s energy independence.

The Application Phase—which ends on June 30, 2014—will be followed by Quarterfinals, and Semifinals, and will conclude in 2017 when one winning community is awarded a $5 million prize purse for use on energy efficiency programs. More information about each of the competition’s four stages is available at www.guep.org/rules-timeline.

Stay tuned for more details on the Prize, the City of Cambridge’s energy-saving plan, and to learn how you can support our efforts. In the meantime, please stay connected with us through this blog, our Facebook page, and Twitter @CambEnergy.

We are excited to get underway in the competition and we look forward to elevating the City of Cambridge as a national leader of energy efficiency efforts in America.

Help us get there! For questions about the Prize or if you would like to get involved in the effort, please contact Meghan Shaw at outreach@cambridgeenergyalliance.org.

 

[1] According to the Lawrence Livermore National Laboratory, using Department of Energy/Energy Information Administration data from August 2010, out of all energy produced, the U.S. has an energy efficiency rate of 42 percent, which means 58 percent of all the energy we produce is wasted: www.llnl.gov/news/newsreleases/2010/images/energy-flow-annotated.pdf.

Prepare for Winter in your Rented or Multi-Family Home

Posted on by

As the weather gets chillier, we all start looking forward to—or dreading—winter. In order to be comfortable while still being energy smart, there are some easy but important steps you can take. There is plenty of information out there on how to weatherize your entire home to keep heating costs down, but many of those actions don’t apply to people who are renting or living in a multi-family condo. Here are some tips that will still insulate your home and lower your heating bill even if you aren’t able to do bigger things like replace your boiler or add insulation in your walls:

  • Place 3M window insulator film on the inside of all of your windows to restrict drafts. It goes on and comes off easily without leaving a mark, and it’s a very cheap solution.
  • Programmable thermostats are inexpensive and need only a screw driver to install, so depending on your heating system type you can install it and then uninstall it when you move out.
  • Open your curtains during the day to take advantage of solar heating and close them at night to keep the heat in.  Some curtains also have insulating properties.
  • If you rent, ask your landlord to take advantage of the free Mass Save Energy Assessments and mention that CEA can help landlords with energy projects.
  • Use draft stoppers underneath doors that lead outside or to an unheated hallway or staircase. They are usually cloth tube-shaped objects filled with foam or pellets (like a bean bag). You can even put them underneath doors for rooms you plan on heating with a space heater to fully block cold drafts coming in from the rest of your space.
  • If you heat with oil, which is notoriously expensive, you can save on your bill by investing in a floor-standing electric space heater to more cheaply heat the room you are currently occupying, while keeping the thermostat low. You can save 3% on your heating bill for every degree that you turn it down.
  • Keep your thermostat very low (but above 50 degrees so your pipes don’t freeze) while no one is home, and put it as low as is comfortable when you are home and awake. Before you go to bed, turn it back down a few degrees. If you have warm blankets and a space heater, you won’t need to heat your whole space any more than that.
  • If your home has radiators, place an insulating panel between it and the wall. Insulating radiator panels reflect heat away from the wall and out into your home, improving radiator efficiency by 10-20%.

With these quick fixes, and perhaps a hot cup of tea each night, you will stay comfortable all winter long without using too much fuel or electricity.

Cambridge Unveils Solar Map

Posted on by

In collaboration with MIT and Modern Development Studio, the City of Cambridge has put together an incredible online tool that will help spur solar development throughout the city.

In this “solar map,” to be launched on October 3rd, Cambridge has been overlaid with a layer of highly specific solar data. Any resident or business owner interested in installing solar on their roof can use the map to access information about their property’s potential without having to scour the Internet. You can click and drag your mouse, browse and choose rooftops at random. Alternatively you can search for a specific address and view information on the solar potential of the building’s rooftop, as well as financial, environmental, and installation details. Color-coding gives you an idea of the varying ability to catch decent sun rays at each point on a roof.

I was able to find out within seconds that my own building, for example, has a total roof area of 1,150 square feet and enough potential to host a 5-kilowatt system. The system would have a payback period of six years and could save the tenants approximately $2,847 per year in energy bills. That’s pretty convincing math. Now, if only my landlord were keen on the idea!

New York City, Boston, Los Angeles, San Fransisco, and Berkeley, CA all have solar maps up and running or in progress. Although some existing solar maps also calculate solar potential, none are quite like Cambridge’s. It is so far unique in that it uses more nuanced data to create as much accuracy as possible. For example, some solar maps assume all rooftops are flat, which can greatly alter a roof’s potential. The map’s creators also calculated solar radiation on an hourly basis, yielding more accurate and detailed information for each roof.

It is becoming more and more popular- and feasible- to power your home with solar energy. Costs have come down exponentially and they are only declining. Cambridge already has a over 110 projects installed on homes and businesses, as many residents have taken advantage of the lower electricity costs, increased property value, and reduced environmental impact that comes with generating over 1.6 MW solar power. It’s clear that there is vast solar potential in Cambridge. This map will prove to be an invaluable tool for homeowners, landlords and business owners who are interested in investing in solar but might not have the time or expertise to find all the answers themselves.

Report Shows Schools’ Environmental Progress

Posted on by

Cambridge Public Schools published its 2012 Sustainability Year-In-Review this summer and celebrated several environmental successes. The report outlines the schools’ environmental progress and accomplishments in energy reduction, recycling, eco-friendly products and other green topics.

Over the past two years, multiple energy-efficiency projects have been implemented. The result is a net projected annual savings of $295,738 for the whole school district; 618,313 kWh of electricity savings; and 29,863 therms. Projects included:

  • the installation of a high-efficiency condensing boiler at the Longfellow School Building
  • high-efficiency lighting and occupancy sensors at the Peabody School, Kennedy-Longfellow School, Baldwin School, Haggerty School, Morse School, Solomon Garage, and High School Field House
  • the installation of Direct Digital Control systems at nine schools
  • additional energy upgrades

But energy isn’t the only area of improvement. Custodians now use metered green cleaning supplies, and six schools are now composting their lunch leftovers. From March 2009 through April 2012 the King Open School alone composted nearly 20 tons of food scraps. The school’s food waste is picked up and taken to a farming facility in Massachusetts for composting as part of the “Food to Flowers” program. The Cambridge Green Schools Initiative also partners with local organizations such as “Walk-Ride Days” and the Cambridge Health Alliance to promote sustainable and healthy modes of transportation.

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

Posted on by

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 every six or seven years.”

With only three and a half months remaining the Cambridge Energy Alliance is urging any business, non-profit, or resident that is considering solar to install a solar hot water system now, while generous grant money is available.  Many people will also qualify for a 0% interest rate HEAT loan, meaning they can put in a system with no upfront cash needed.

Claudia Majetich, of Concord Avenue is pleased with the solar hot water rebate, saying “The Cambridge rebate program for solar hot water is a wonderful help to home owners who need to replace their hot water systems.  It makes our installation costs very affordable–just about the same as a new gas or oil system.  And that doesn’t even include the savings I’m anticipating from reduced oil usage.   Staff at the Cambridge Energy Alliance returned my calls right away, and provided lots of helpful information.  Great program, Cambridge!”

Residents are not the only ones who can benefit. Businesses like gyms, laundromats, restaurants, and hair salons are excellent solar hot water candidates. Solar hot water installer Eric Lorenz of S&H Construction points out that “business owners investing in solar hot water systems can realize a 20-50 percent savings in monthly fuel costs, expand their marketing opportunities to reach new audiences and simply enjoy the fact that they are harvesting the sun’s energy for use in their day-to-day operations.  Installing solar guarantees a positive return on investment and with current incentives in place today, the returns are the best they have ever been.”

To get started, contact a local solar hot water installer and apply for the Massachusetts Clean Energy Center (MassCEC) rebate. After receiving the MassCEC rebate, Cambridge residents, businesses and non-profits can apply for the non-competitive CEA Solar Hot Water Grant.  The CEA Solar Hot Water Grant will reimburse system owners up to $2,000 for out-of-pocket costs after all other rebates and incentives have been calculated.

Solar hot water systems provide an easy and low cost way to make hot water sustainably. Solar hot water systems heat water for laundry, bathing and even space heating. Anyone with heating oil can expect a short 5-year payback on the investment.  A solar hot water system generally works in conjunction with your existing hot water heater or utility incentives can be used to replace old systems with new, super efficient hot water heaters and boilers installed in combination with solar hot water systems.

Solar hot water systems generate heat from sunlight to make hot water. Roof mounted solar ‘collectors’ for hot water systems look very similar to solar photovoltaic (PV) panels, which generate electricity rather than hot water.  A solar hot water system can be connected to a building or home’s existing hot water tank to heat water. Some solar hot water systems can also connect with the heating system to provide space heating.  Because about 20 percent of the energy a consumer uses at home goes to heating hot water, solar hot water systems can generate significant savings by decreasing the amount of gas, oil or electricity used to heat the water.

To find out more about solar hot water, see the MassCEC Solar Hot Water Fact Sheet.

The Cambridge Energy Alliance grant will amount to approximately $2,000 for a typical solar hot water system for a four to five person household, in addition to the approximately $1,000 in MassCEC rebates.  Combined with other federal, state, and utility incentive programs, the total rebate can cover more than half of the cost of a system. Cambridge Energy Alliance’s Solar Hot Water grant is funded with $40,000 from the federal Energy Efficiency Conservation Block Grant.

Get started by calling a local Solar Hot Water installer to begin MassCEC’s Commonwealth Solar Hot Water rebate application.

Applications for the CEA Solar Hot Water Grant must be received by November 19, 2012. CEA Solar Hot Water Grants cannot be processed until you complete the MassCEC Commonwealth Solar Hot Water application process.

Solar rebate programs have helped spur a vibrant solar industry in Massachusetts. According to a MassCEC survey of clean energy companies, employment in solar manufacturing, installation, and services has increased nearly three times since Governor Patrick first took office, and solar manufacturing jobs alone have close to tripled from 2007 to 2010.

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 City’s Green Community commitment to reduce energy use by 20% from its FY08 baseline. Energy efficient lighting technologies have been installed in 22 municipal buildings over the past two years with a projected total savings of 1.3 megawatt hours/year.

Stay tuned for future energy efficiency upgrades!
