Tax credits and incentives for energy efficiencies

I’ve just started a study of the numerous incentives, grants, tax credits, and rebates that are available at the federal, state, and local level for alternative and energy efficient products. I expect with the new administration in Washington this should get even more exciting over the next few years.

To get started, you might try this website which has links to both federal and state programs. Start by choosing your state:

You do have to read some of the details to understand the type of incentive, the qualifications and the limitations. Part of my service to the Enfield, NH community when I open the Energy Emporium store will be to point people to the incentives that apply to them and help them get through the process.

As an example of what is available from the federal government as well as for residents of NH, I have listed some of the incentives below.


Residential renewable tax credit – up to 30% of the project with caps for each kind of renewable. The residence must be the primary residence of the taxpayer. This tax credit was recently extended beyond solar systems to include geo-thermal and wind. Definitely look it up!

There is a similar business energy tax credit that provides 30% for solar, fuel cells, and wind renewables, and a smaller credit (up to 10%) for microturbines and geo-thermal.

Residential energy efficient tax credit – up to $500 for certain energy efficient improvements made in 2009 to a primary residence.

Personal exemption incentive –Energy conservation subsidies are non-taxable.

Also, don’t miss the Energy Star website to get more information on the US Department of Energy’s rating systems, products, energy audits and related information.

New Hampshire:

Renewable energy rebate (solar water, voltaics, wind) – $3 per Watt up to $6000 or 50% of cost of system, available in July 2009. This is the one everyone is talking about… be sure to look it up!

Property tax exemption for the cost of a renewable energy systems (has to be voted in town by town). Property tax should not increase due to upgrades in heating systems.

Low Income Energy Assistance – Grant program up to $3600 for increasing the efficiency of home or appliances. Need to meet income guidelines.

Utility Rebate programs – these come from the specific utility company that you are using and sometimes include a free energy audit of your home. Some examples are rebates for upgrading lights, improving insulation, upgrading appliances. Use the DSIRE link to find your utility company’s links.

For the Leviston House project (retail space on the first floor, two apartments on the 2nd and 3rd floors), we will look into some of the small business incentives such as the Solar Thermal Rebate program for multi-family houses and the Small Business Energy Efficiency programs which offer both grants and 0% interest loans.

What we can build – Alternative Energy Products

Barak Obama

Barak Obama

Barak Obama:
“To those leaders around the globe who seek to sow conflict, or blame their society’s ills on the West — know that your people will judge you on what you can build, not what you destroy.”

This is my favorite quote from the inauguration speech yesterday. Obama has pledged to put emphasis on alternative energy systems. He wants to help create 3 million jobs and expects many of them to be in the field of products and services that will help save the environment.

I hope we are all judged by what we build and what we add to this world, and that America can become a leader in alternative energy products and services.

Here are some interesting links of alternative energy websites. Send me your best picks so I can start a blog roll: – Driving sustainability ideas, products, information – Environmental news and information – Environmental news and humor – What sustainability means to you – Green auto industry – Alternative Energy solutions – Retail stores for alternative energy and sustainable products – Carbon footprint – Carbon footprint – Promoting sustainable lifestyles – Save energy, money and the environment – Green building – Diminishing fossil fuels; increase sustainability

Alternative energy watches … back in style



Clocks and watches have been around for hundreds of years now and they didn’t originally depend on electricity to run! So it makes sense that there quite a few ways to run one without plugging it into a wall or using batteries. The first time pieces were powered by the sun, sand or by water.

I love the mechanism of the grandfather clock using gravity and weights to keep time moving forward.

Mechanical springs have been a good way to power watches for centuries.

I inherited a clock from my grandfather that runs on change in barometric pressure. It sits under glass and should not be moved at all in order to keep its accuracy.

And then there’s the potato clock.

As a kid I was very excited to receive an ‘automatic’ watch with no battery. It was a self-winding watch that kept running simply by wearing it. I do remember shaking my wrist from time to time just to hear it wind.

I had that watch for many, many years. Then the next 20 years I had many, many watches with batteries. For the most part, the work required to replace the battery generally wasn’t worth keeping the watch running.

About 2 years ago my father, who is always looking for alternative energy products, found a new series of watches that are run on solar power using photovoltaics on the surface of the face. Between this technology and the self-winding watches, which have now become popular again, you can get a watch that doesn’t need batteries! I highly recommend it!

Search for ‘eco-drive’, ‘solar watches’, or ‘self-winding watch’ to find them. Here is a link to my watch:

Environmentally friendly roadside assistance

Since I started blogging I’ve gotten quite a few interesting links forwarded to me from readers. One of them was particularly timely — a roadside assistance program. Both my car and my husband’s car have gone past that 70,000 mile mark, and we’ve paid off the loans, and there is more of a chance that they will need a tow or will break down for some reason. We were members of AAA years ago but at one point in our lives we had two brand new cars and decided we didn’t expect to use it enough to justify the cost.

As of the beginning of this year my husband works in Boston, I work in Enfield, New Hampshire and one of us will be driving many miles in older vehicles each weekend to visit the other. So I thought I would look into restarting my AAA membership.

Then I got this timely email from a friend about the Better World Club. I didn’t even know there were options for roadside assistance!

As opposed to being partners with car companies that want to sell us gas guzzlers, the Better World Club is an environmentally friendly roadside assistance program. They have bicycle assistance programs and they provide discounts for people with hybrids, electric or biofuel cars!

They have competitive rates with AAA and encourage eco-travel destinations and renting hybrids when traveling. Sounds great to me. Check them out!

I’ll report back in a few months when I’ve had a chance to use their services.

Case Study – basement insulation

My father-in-law has recently added significant insulation to his basement windows and bulkhead. He created some great ways to plug the holes using bubble wrap and insulation in ways that also make it easy to install for the winter and store them away for the warm months.

He provided me with data from his oil bill, as well as the degree day information from his oil company for the years before and the year after this improvement.

One of the first problems I thought about in reviewing his data was that oil fill-ups don’t correspond well to the days that the oil was burned. I can see that there were 100 gallons put into the tank in March, for instance, but I can’t say how many of those gallons were used in the next week or the next month. The oil that goes into a tank in May may not get used until September.

The second problem to consider was that the oil company provided 9 months  of degree data — from September to April. So, to try to match this up to the months when oil was added to tank required a little guesswork. I ended up throwing out some gallons of oil, hoping that I was making good guesses.

In the end, I did the calculations and spreadsheets three different ways, each a little more precise than the first. Below is the summary of the first (simplest) and third (most complex). The middle one provided data closer to the third, but basically in the middle.

Simple Analysis:

In the simple case, I used the oil company degree data AND the oil fill up data for only the months of September through April. After looking up a couple of estimates of kWatt-hours per gallon of heating oil, I used 1 gal=41KWh (which doesn’t take into account the efficiencies of the oil burner). I found an average number of degree days from the 5 years given by the oil company, 6245, and used that to ‘normalize’ the kWh and gallons of oil.

Year Gal of Oil kWh Deg Days kWh/DD Norm kWh Norm Gal Savings
2004-2005 1169 47929 6487 7.4 46141 1125 -$33
2005-2006 1036 42476 6020 7.1 44064 1075 $93
2006-2007 1089 44649 6116 7.3 45591 1112 $ 0
2007-2008 972 39852 6042 6.6 41191 1005 $268

The first few columns are the numbers provided by the oil bills and the degree days provide by the oil company. The normalized kWh and normalized gallons are the amount of energy or gallons of gas your heating system would have used if there was the exact same number of degree days in each of these years. Now we can compare 2007-2008 against 2006-2007 and there is a savings of about 10%, which would be $268.28.

After going through these numbers I felt it would be much better if I could get a full year of data and more detailed degree days and see if the result was better. I used the degree day data from this website:, where I can set the base temperature and get monthly, weekly or even daily data. That way I can use the entire years worth of oil information as well. The only drawback is that for the zip code near this house, the degree data only goes back 2.5 years. So the monthly detailed analysis is only useful for the last two years.

Complex Analysis:

Year Gal of Oil kWh Deg Days kWh/DD Norm kWh Norm Gal Savings
2006-2007 1225 50221 6075 8.3 51626 1259 $ 0
2007-2008 1011 41467 5913 7.0 43796 1068 $477

These numbers indicate a 15% increase in efficiency (savings in gallons of oil) between 2007 and 2008, which translates into a savings of $477 in a ‘typical’ year. That’s pretty nice.

There is a big difference between the first ‘simple’ estimate and the final one. The differences in the calculations that lead me to believe the final savings number is a better estimate of the savings than the simple one are: 1) I used more sophisticated degree day data, which allowed me to set the proper base temperatures and work with monthly data; and 2) I used the full year of data for both the oil fill ups and the degree data and set the calendar year to go from June to June assuming that the oil in the tank during the summer months was not used quickly.

I expect to return to this case study next year to see if the numbers are consistent. If you want the more detailed spreadsheet of numbers for this case study, please write to me at kim at
