NON-PROFIT organization. Save on heating oil with local dealers, all year long. Our Heating Oil Service works like a buyers club or co-op for home heating oil and is available to most households in Massachusetts, Rhode Island, and southern New Hampshire. We use the group buying power of our 11,000 members to negotiate a discounted price per gallon with vetted oil dealers every day of the year. How it works: 1. Enroll in the program and pay your annual membership dues ($25 for a basic 1-year membership). 2. Once you’ve enrolled, we pair you up with one of the oil dealers in our network that meets your delivery, payment, and service preferences. 3. Every time you receive a delivery from your new Mass Energy oil dealer, you get the discounted member price per gallon instead of the price they charge their regular customers. That's it! As a bonus, we'll help you save even more on energy by helping you make smart decisions around energy efficiency and renewable energy upgrades. (Formerly doing business in Massachusetts as Mass Energy and in Rhode Island as People's Power & Light.)

"Always pleasant interactions with staff. You can tell that they are proud of what they do and are genuinely invested in the company’s causes."

SolarFlair works with businesses and homeowners that are interested to reduce their utility bills and their carbon footprint by converting to solar power. We are a licensed and certified solar engineering and design firm with over 10 years of experience in the industry. We do not use subcontractors and have over 200 satisfied clients that are happy to share their SolarFlair experience.

"The original installation process went very smoothly, however,, A few years after the panels were installed, a leak developed at one of the punctures for the panel mounts. we first called back the roofer to see if the leak was not due to the solar mounts, but he confirmed that the leak was indeed right under one of the mounts. SolarFlair came to take a look and applied a product to the interior of the roof which did nothing to stop the leak, they came back and applied roof tar on the outside which again did not stop the leak. this process has been very frustrating for the lack of communication, the slowness and incomplete response to the issue. They've closed out the work each time they've done something before veryifying that the leak has been fixed (it still has not been fixed). The company had taken over 9 months from our inital call, and we still have a leaking roof. we have very little communication from SolarFlair as to what actions they have taken, and what next they could do. it seems clear that part of the roof needs to be replaced to fix the leak."

Energy Efficiency Auditing questions, answered by experts

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

A whole-home humidifier can impact your energy bill positively. In colder months, humidified air feels warmer, allowing you to lower your thermostat without sacrificing comfort. This can lead to energy savings as your heating system works more efficiently. However, it's crucial to use the humidifier judiciously to avoid excessive humidity, which might strain your cooling system in warmer months.

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

There are several indications of an overloaded electrical panel, such as frequent circuit breaker tripping, burn marks, or flickering or dimming lights.

If you’re observing any warning signs, turn the circuit breaker off, then shift some devices from the overloaded circuit to a different one. If there are still signs of overload after turning the circuit break back on, contact a professional electrician to help you fix the issue.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.
