Understanding Your Personal Energy Use

National Geographic has built a pretty interesting online resource for looking at your personal energy consumption compared to your friends and neighbors. The tools are all part of The Great Energy Challenge designed to help you understand your current energy situation.

The tools range from easy-to-digest mini-calculators to the more comprehensive personal energy meter. I found all of the tools educational, but learned the most from the mini-calculators. Personal note: I need to take care of the energy vampires that lurk in my house!

Let’s Talk Home Energy

Have you ever wondered what uses more energy in your home — heating, cooling, lighting, or powering electronics like TVs, computers, and refrigerators?

No surprise it is heating. I bet you are not too surprised, after all, Greenwood is a renewable heating company. However, what may surprise you is to what extent it outpaces other energy use in your home.  As a homeowner, the U.S. Energy Information Administration presents a rather compelling picture for home improvement.

Two-thirds of the energy used in your home is for heating. Time to upgrade the windows, add insulation, pull out the caulk gun and (here it comes) look at cheaper forms of heat like a high-efficiency wood boiler. Sales pitch aside, the biggest dent you can make in your monthly energy bill is take a bite out of the heating gremlin.

Happy caulking!

Time Running Out on 30% Tax Credit

December 31st, 2010.

That is the date that federal tax credit is scheduled to expire for the purchase of new energy efficient products, including high-efficiency wood boilers. With the purchase of a qualifying product, the government will credit you 30 percent of the cost (and installation), up to $1,500.

So, why is this a big deal? Well, a tax credit is much more valuable than a tax deduction.

A deduction is an amount you can subtract from your taxable income. However, a tax credit lowers your actual tax bill dollar-for-dollar, in this case by up to $1,500. So a tax credit has a bigger impact on the money left in your pocket at the end of the day.

So, whether you are considering a wood gasification boiler, air conditioner, water heater or windows time is running out.

For more information, BuffaloNews.com has a great article.

Department of Energy: Green heat is often most cost-effective option

US Federal agencies purchased or produced 2.3 TWh of electricity from renewable sources in FY09, representing 4.2% of the Government’s electricity and surpassing the goal of 3% set by EPAct 2005. This represents a 2x increase over 2003. The goal increases this year to 5% of total electricity from renewable sources, and increases again in 2013 to 7.5%.

Perhaps what is most fascinating is that this figure does not include non-electric renewable energy purchased or consumed by the Federal government — sources like bio-thermal space heating or solar thermal hot water. However, according to a Kathleen Hogan, Deputy Assistant Secretary of the Department of Energy’s Office of Energy Efficiency & Renewable Energy (EERE) testimony, “The renewable sources of non-electric energy are often the most cost-effective means to displace fossil energy,” she explains.

With that acknowledgment, what steps can be taken to insure the adoption of these cost effective sources?

One way is increase subsidies to promote adoption, much like those in H.R. 5805: Thermal Renewable Energy and Efficiency Act of 2010. Unfortunately these are only focused on large scale applications. An alternative would be to look to other countries where these alternative technologies have been employed and implement their approach — incentives targeted at residential heating.

The State of New Hampshire’s Wood Pellet Boiler Rebate program is an example of such a program. It is narrowly focused on wood pellets, but removes much of the upfront cost of implementing a system that makes a homeowner energy self-sufficient.

The Rise of the Urban Forest

If you thought that forests were a rural phenomena, you will find the data compiled by a Dovetail Partners report eye-opening. In their report, Urban Wood Utilization and Industrial Clusters, they describe the growth of the urban forest in the lower 48 states from an area the size of Vermont and New Hampshire in 2000 to the size of Montana in 2050.

Equally interesting is the discussion about the volume of wood, removed annually from urban forests. The amount is significant — from 16 to 38 million green tons per year. This is more than the total annual harvests from America’s National Forests. Yes, you read that correctly.

This report focuses on an emerging urban wood-based industrial (business) cluster in the Minneapolis-St. Paul (Twin Cities) metropolitan area. Examples of Twin Cities’ cluster-based wood utilization activities and corresponding cluster-building techniques are highlighted. Recommendations for advancing wood utilization activities on a community-wide basis are offered.

The complete report may be found here.

The Rise of Eco-Pragmatism

We are setting up a show-down among three recently hot topics – energy, economy and environment.

Looking back over the past year is quite interesting. We have had oil (and its derived products) reach historic price levels. We have seen unprecedented awareness in schools and on main street regarding greenhouse gases and environmental issues. Finally, we have the economic events of the past few months that have cast a dark shadow of uncertainty over it all.

The average person can wrap their arms around one issue or decide between two competing objectives, but it gets more complicated when you need to choose among three competing interests.

People are increasingly looking at their pocketbook and asking themselves – “I like the idea of being environmentally friendly, but how much is it worth to me?” Of course, this is being driven by increasing economic uncertainty. Good environmental ideas from last month are still good ideas, but I would submit that we begin to see a shift toward more practical ideas from consumer attitudes and behaviors.

This eco-pragmatism (evaluation of an action or purchase based on the practicality of the good or service as part of its environmental impact) can be contrasted with greenwashing  (application of an eco-friendly label or classification to a product (often inappropriately) so that it appears to be eco-friendly) that you have undoubtedly been subjected to as you walk down the aisle at your favorite store.

In the coming year, I think we will see a more products that offer a positive economic impact while improving an environmental concern. Costly items like solar panels and wind turbines will still have their buyers, but clean-tech pellet and wood boilers will share the spotlight. While the latter does not provide the air quality improvement of the first two, it is a significant improvement over a conventional fossil fuel.

Vermont Outdoor Wood Boiler Event

The U.S. Environmental Protection Agency (EPA) and the State of Vermont have been leading the charge to reduce the emissions on outdoor wood boilers, so it makes good sense that they chose Waterbury, VT to announce the EPA Phase II voluntary program. We were on the grounds of the Vermont Department of Environmental Conservation with a number of other manufacturers (including Hardy and Northwest Manufacturing) to support the EPA announcement on cleaner outdoor wood heaters.

We were able to chat with many of the people responsible for the program including Phil Etter (VTDEC) and Gil Wood (EPA).
Our local dealer (Johnson Hardware) did a yeoman’s job getting a unit up and running so we could demonstrate the operation and performance to government officials. There is nothing like opening up the secondary firebox door and watching the wood gasification process taking place in the Greenwood Carbon Reactor to leave an impression.

There was also a lot of press at the event – take a listen to what Vermont Public Radio has to say about the event.

EPA Phase II Announcement

This past week we were in Vermont for the EPA’s announcement of the Phase II Hydronic Heater Program. After you get past the name (which is a general term that refers to pellet, corn and wood boilers) you might ask  yourself what is so significant about this program?

First, as a consumer it means that there will be able to identify cleaner wood and biomass products from other dirtier products. The cleaner products carry a White Tag rather than the Orange Tag (from the Phase I program). These new units are 90% cleaner than traditional wood boilers rather than 70% cleaner than those that complied with the Phase I standards. Some products (like the Greenwood Aspen Series) qualified for both Phase I and Phase II. 

The second distinction is that it places all residential biomass heating appliances in the same category. This is similar to a fuel mileage rating system for automobiles where SUVs and hybrids gas mileage can be compared. In the case of wood boilers, the rating provides you an understanding of what type of output you get based on your fuel preference or installation location. Indoor and outdoor products as well as pellet, corn and log wood fuels are all on the same scale. As a consumer you have more information in which to make your decision.

Expect to hear a lot more about the White Tag or for more information head to the EPA site.

Understanding Biofuels

With fuel prices where they are these days, there is a lot of talk about domestically available options. One type of fuel that is central to the debate is biofuel. You may recognize them by their other names – ethanol, biodiesel, biocrude, methanol and methane to name a few.

Don’t freak out on me, this is not your high school chemistry class, but there are some big questions that arise that are still under debate and as consumers of the product/byproduct it is important that we understand what is being discussed.

Central to the biofuel discussion are two fundamental debates:

  1. Energy and Food Supply. Early biofuel supplies were built using a corn and other food supply feedstocks. Should energy products compete with the food supply?
  2. Energy Conversion. Biofuels are created from organic material (e.g. corn, switchgrass & crop residues). What amount of energy is required to create the fuel from these feedstocks? If the amount of energy required to produce the fuel is less than the output from the resulting fuel, is it worthwhile? The conversation is a bit heated.

These are not simple questions. However, their answers are arguably simple – each resource should be used to provide its greatest return. In the questions we ask above — I would argue that food supply should remain as food supply. We can use the crop residue for energy. As far as energy conversion, I don’t need to look any further than modern biomass heating options with efficiencies greater than 70% (per US standards). Until the economics or science indicate otherwise perhaps we should be selective in our choice of the feedstocks for biofuels.

As someone who has made it this far, implies some level of interest, so I encourage you to take a look at this resource from Farm Credit of Canada that provides an overview on the biofuel discussion.
