Electrify Your House

Electrify Your House


Converting all our energy use in houses, businesses, and other island buildings to electricity is key to our reaching 100% Renewable by 2040 goal. All of these ideas will help you make your house more efficient and fossil-free. Start with one idea and then keep ongoing. And tell your friends and neighbors to do it too!

Do the Easy stuff


The Cape Light Compact offers a green electricity supply program-Cape Light Compact Local Green

All the electricity for this program is from renewable sources around New England.

Sign up to make an easy switch that supports renewable energy generation in our region.


Get the free energy audit done from the Cape Light Compact and then do what they suggest.

Switch to LEDs– they give the same light at 1/4 the energy usage. A warm bulb- 2600-3000K will give off light like you are used to.

Check your temperatures  37-40 degrees fridge, 0 degrees freezer, 125 degrees- hot water.

Cut summer energy bills by using your clothesline instead of the dryer.

Go EnergyStar for appliances.


Help us reach our goal of 100% Renewable by 2040 by turning things off or down when you are away.

If you are a seasonal resident, turning your refrigerator off or at least filling it with bottles of cold water,
turning off your hot water and turning your heating system off or way down are all significant ways to help us meet our goal.

If you live here year-round, turn off lights, TVs, computers and other things that are a constant use of power when they are not in use. It makes a difference!

Make Your House Be All That It Can Be!


A blower door test tells you where your house is leaky. Fixing those gaps will make your house more comfortable and save you money.

Once your house is nice and tight, bathroom fans on timers or a recovery ventilation system will ensure you get a controlled flow of fresh air.

Have an audit done by the Cape Light Compact or a HERS rater to see where your house needs help.


An energy audit can tell you where there are gaps in your home’s insulation. The auditors can help you arrange for insulation work to be done.

Adding a layer of rigid insulation to walls when you replace windows and are re-siding or when you replace your roof shingles, adds an extra
blanket of insulation that will make your house warmer in winter and cooler in summer.

Both of these things will save you money on your energy bills.


We all use hot water and have hot water heaters already connected in our houses. Hybrid electric water heaters use heat pumps to make hot water and are the most efficient option out there today.

They draw heat from surrounding air and need at least 7 x 10 area to get that heat from. A basement, if at least 50 degrees in winter, will work

Go All Out Electrically!


Cold climate heat pumps are the most efficient way to provide heat and cool for your house. They can replace your existing system or supplement it.

Make sure your house is nice and tight and well-insulated to get the most out of this technology.

Get your electricity from renewable sources to go one step further.

Solar has come a long ways since the first system was installed here in 1998. It is cheaper and way more efficient.

If you have an unshaded, south-facing roof or ground area, read here how it works and how much it might cost. 

We have a number of solar installers here:  Bennett Electric, Cotuit Solar, Fullers Energy, Harvest Sun Solar, My Generation Energy, South Mountain and maybe others. David Smith is one possible person who offers consulting to help evaluate proposals.


We have a tremendous resource available to us by virtue of our living by the coast– offshore wind.

Solar can help us with our home energy needs and maybe even power some of our cars; offshore wind can help us to power our ferries, trucks, buses, construction equipment and our larger buildings.

It is a key player in our meeting our 100% goal.

Join Vineyard Power and support efforts to get this key resource up and running.

Go The Extra Mile


As you replace outdoor equipment — lawnmowers, trimmers and leaf blowers–go all electric.

The electric models are quieter, emit less fumes and will help us reach our goal.

If you have a landscaper, ask them to go electric as well.
