More tips

Heating oil members, perform regular system tune-ups to make your heating system run more smoothly, and if it's time to purchase a new heating system, we recommend choosing a system that is Energy Star rated.

We encourage those who are considering installing solar electricity or solar hot water systems to make sure they are already using energy efficient lighting and appliances, and low-flow faucets so they can get the most out of their solar energy investment.

And we encourage everyone to install energy efficient lighting and appliances so that they can invest their savings into the purchase of green electricity. Customers can offset the additional cost for New England GreenStartSM by implementing cost-saving energy efficiency measures in their homes, such as those described below.

Why make your home more energy efficient?

  • Lower Energy Bills! Much of the energy we pay for is wasted. Your energy bills can be cut by 10-50% through a few inexpensive energy-efficient measures.
  • Less Pollution! The burning of fossil fuels causes global warming and poor air quality. Furthermore, the extraction and transport of coal and oil result in harmful environmental impacts.
  • Energy Independence! Our dependence on foreign oil leads to geopolitical conflicts.
  • More Comfort! By looking at how the various components of your house work together as a system and taking a whole-house approach to energy efficiency, you can eliminate drafts, make your energy systems more responsive to your needs, and avoid unhealthy moisture problems.

Why are your energy bills so high?

Some of the biggest sources of energy inefficiency in the home are

  • Leaky windows and doors
  • Un-insulated roofs and exterior walls
  • Old, inefficient appliances, particularly heating systems, refrigerators and air conditioners
  • Incandescent and halogen lighting
  • Leaving lights, computers, and other appliances on unnecessarily
  • Heat is turned up too high or air conditioning is turned too low
