The Future: Energy-Producing Diapers

Thursday, November 19th, 2009

As I was listening to the radio the other day, I heard a very interesting report on diaper recycling/fuel production. Yes, you read correctly. This company in the UK is recycling soiled diapers and producing green fuel. As part of the recycling process, the materials are sterilized, separated into individual components which include organic residue, plastic and super absorbent polymers. These components are then recycled into plastic wood, plastic roofing tiles, absorption materials, recycled paper products, among others. What really caught my attention was the production of green energy! If I heard correctly, six megawatts of green energy were produced in the recycling process. One was used by the company to operate the plant and the other five megawatts were sold to the local grid. Go green! That’s a great way to reduce even further the amount and toxicity of our garbage.

Personally, when my children were babies, I didn’t consider which was the most environmentally friendly option when choosing diapers.  I just selected the most convenient method for our family: disposable diapers. It’s interesting that several months ago, in one of our Questions of the Week on diaper selection, we had a very interesting green conversation going with well over 170 people weighing in on which is the best option for the environment, disposable or cloth diapers. There are many articulate arguments in favor of both options.  At least, companies like this one are finding creative ways to reduce waste while having the added bonus of producing green energy.

As I was reading up on the issue for this blog, I learned that it can take 450 years for a disposable diaper to disintegrate in the ocean, and over 500 years in landfills. While we all should make an effort to adopt more environmentally practices to reduce waste, it gives me hope that at least in the case of disposable diapers there is some hope to go green. So, will we be talking about baby power at a recycling center near you? That might be the way of the future.

1 Million ENERGY STAR Homes And Counting

Tuesday, November 10th, 2009

I have worked with the ENERGY STAR for New Homes program for nearly 10 years - first as the program’s Partner Support Coordinator and now as its Communications Coordinator. When I first came aboard in 2000, less than 14,000 ENERGY STAR homes had been built since the program first kicked-off in 1995. Today, I am truly amazed that we have reached the milestone of 1 million ENERGY STAR Homes built. I could not be more proud!

Consider some of these numbers:

  • This year, families living in the 1 million ENERGY STAR homes will save more than $270 million on their utility bills, while avoiding greenhouse gas emissions equivalent to those from 370,000 vehicles.
  • There are more than 6,500 builders across the nation currently building homes that earn the ENERGY STAR label. These range from the largest national homebuilders to small custom builders to builders of manufactured and affordable homes.
  • Nearly 17 percent of all single-family homes built nationally last year earned the ENERGY STAR label, up from 12 percent in 2007. And market share for ENERGY STAR is 20 percent or greater in 15 states.

To earn the ENERGY STAR label, a home must meet strict guidelines for energy efficiency set by EPA. ENERGY STAR homes are at least 15% more efficient than those built to the 2004 Energy Code, and include additional energy-saving features that make them 20-30% more energy efficient than typical new homes. They achieve these energy savings through established, reliable building technologies and a whole home approach to home building, including: effective insulation systems, high-performance windows, tight construction and ducts, efficient heating and cooling equipment, and high-efficiency lighting and appliances. An independent Home Energy Rater conducts onsite testing and inspections to verify that the home’s performance meets ENERGY STAR requirements.

Our success would not have been possible without the tremendous level of support that our program has received from the organizations that have partnered with ENERGY STAR. From the homebuilders who put our label on their homes, to the Home Energy Raters who do the verification needed for homes to earn the label, to the utilities and other organizations that have sponsored ENERGY STAR in their markets through incentives, training, and consumer education and outreach.

It is truly gratifying to know that by looking for the ENERGY STAR, home buyers can get a home that provides greater comfort, saves energy and money, and helps them join in the fight against global warming.

I wonder how long it will take us to reach the 2 million mark?

Where Does My Electricity Come From?

Friday, September 11th, 2009

One of the marvels of the modern age is the availability of reliable electricity. You do not have to go back many generations to find individuals who grew up on farms or communities without electricity. Ask your parents, grandparents or great-grandparents if they remember life before the Rural Electrification Act of 1935 when only 10% of rural residents had electricity. Or maybe you have experienced being without power for a few hours after a thunderstorm or even for days and weeks following a hurricane.

On most days and nights, if you need electricity to read by or use your computer all you have to do is flip a switch or push a button. But do you know where your electricity comes from? What is the fuel source to your power company?

image of electricity transformer towerOf course, almost all power companies rely on a combination of fuel sources: coal, natural gas, nuclear, hydroelectric, other renewables, or petroleum. In that way, they can shield the consumers and stockholders from large shifts in the prices of commodities and construction for facilities. But a great deal of information on electricity production (residential and industrial) is available from the Department of Energy’s Energy Information Administration .

Twenty states (WV, IN, KY, WY, ND, UT, OH, MO, NM, KS, IO, NE, MI, CO, WI, GA, MN, MD, NC, and TN) generate more than 50% of their electricity from coal. In fact, more than 90% of the power in West Virginia, Indiana, Kentucky and Wyoming is from coal. Only 5 states (RI, NV, FL, MA, and AK) use natural gas for over 50% of their electrical generation. And of those states, only Alaska is a natural gas production state. The others must depend on natural gas transmission pipelines or liquefied natural gas import terminals.

Nuclear power is generated in the fewest number of states and only 5 states (VT, CT, NJ, SC, and IL) generate over 50% of their electricity from this source. Hydroelectric power generates electricity to some extent in a number of states. Over 50% of the power in WA, ID, OR, SD, and MT is from hydroelectric and it is over 85% in Washington, Idaho and Oregon.

Almost all states have some level of electricity generation from renewable fuels other than hydroelectric, including wind, solar, geothermal, and biomass. While the use of other renewables is not at 50% in any state yet, over 10% of the electricity in Maine, Iowa, Minnesota and California is generated from this fuel source category.

Petroleum-fired power plants produce the smallest amount of America’s electricity. And the only state with greater than 50% of generation in this manner is Hawaii, where over 82% of the electricity comes from petroleum-fired sources.

Depending on where you live and the manner in which electricity in your state is regulated, you may have a choice of electricity provider or fuel source. Contact your state’s Public Service Commission or State Energy Conservation Office to learn more about your power options.

Where Has All The Summer Gone?

Tuesday, August 25th, 2009

Gosh, where did the summer go? It’s hard to believe that the kids are back in school and summer is almost gone. The warm weather and trips to the shore will soon be a thing of the past. I guess that’s one side of the coin. The other side is that cooler weather and snow could be just around the corner. There has been a lot of discussion about protecting ourselves from the sun, water quality, and other summer time subjects, but let’s not forget to prepare ourselves for the winter time too!

Sun protection should still be a priority (especially in areas with lots of snow to reflect the sun’s rays), but the next several weeks would be a great time to focus on making some changes around your home to prepare for “Old Man Winter”. Do you have a drafty window or two, maybe water pipes in a crawl space that could use some extra insulation, or how about that maintenance to the furnace or heat pump to get ready for those cold winter nights? These are just a couple of the things I’ve had to do to make my home more comfortable in the past year or two. The weeks between the end of summer and the beginning of winter are a perfect time to make these changes.

Being proactive to prevent problems from arising instead of having to react when a problem occurs could save you not only time and money, but energy too! If you are a do-it-yourselfer, the climate is much more cooperative for doing this kind of work. If you rely on others for taking care of these kind of repairs, I’d venture to say you could probably get a better price and a scheduled appointment rather than having to wait for someone to “squeeze you in” and then pay premium prices to get that warm air flowing through your home again.

Check out some of EPA’s Energy Star resources to learn about sealing and insulating and get some answers to questions you might have about other Energy Star topics to prepare your home for the winter months. What improvements have you made that have really made a difference in your home?  Oh, and by the way, button up, this may be a cold one!!
