Join EPA, BGCA, and Spider-Man in Celebrating Earth Hour this Saturday, March 29th

2014 March 28

Earth Hour

By: Jill Vohr

This Saturday, March 29th, is the 8th annual Earth Hour, a global movement that brings together millions of people across the world to switch off their lights for one hour as a symbol of their commitment to the planet. Are you up for the challenge? As a member of the team at ENERGY STAR, I am excited to participate for pretty obvious reasons.  Turning off lights is a great and easy way to save energy and prevent climate change.  Plus, using ENERGY STAR certified lighting saves energy even when our lights are on.

This year, Earth Hour has partnered with the new Sony Pictures movie The Amazing Spider-Man 2 to make Earth Hour that much more thrilling to people across the globe.  Check out this video to see how the movie stars are playing a part in protecting the environment this Earth Hour.

The Boys and Girls Clubs of America (BGCA), a dedicated ENERGY STAR partner, is also working with the makers of The Amazing Spider-Man 2. BGCA uses the movie’s energy theme to help young people learn about saving energy. The movie villain is called Electro and he attacks by shooting bolts of electricity!

The connection between the movie and the work of the BGCA is a great one, and one that I think works for young people across the country. What better way to get your kids to use less energy than by telling them to “Be Your Own Amazing” by joining Spider-Man to stop Electro and save energy, right?  Even without the movie connection, Earth Hour is its own amazing.  It is a way for individuals across the globe to come together to make a difference for the planet through local activities.  And that speaks to us at ENERGY STAR, because we are passionate about using energy efficiently.

Did you know that the average home spends about 12% of its electricity bill on lighting? Lighting accounts for more of the energy that you use than your laundry equipment, refrigerator and dishwasher combined. That fact alone should be a good reason to switch off the lights (non-essential ones) and give Earth Hour a try this weekend. We know that our kids want to be heroes like the Amazing Spider-Man.  So by turning off the lights this weekend, we adults can certainly be our own amazing, too.

Earth Hour will take place on Saturday, March 29th between 8:30pm and 9:30pm in your local time zone.

About the Author: Jill Vohr is the Director of Marketing for the ENERGY STAR Labeling Branch.  When she is not pursuing strategies that encourage individuals to use less energy – she is using up a lot of her own energy with her 7-year old daughter, Ingrid, who thinks spiders are icky.

The ENERGY STAR LED Bulb Challenge

2014 March 13

LED bulb challenge

By: Brittney Gordon-Williams

Did you know that nearly 70 percent of sockets in the U.S. still contain an inefficient light bulb? It may be hard to believe, but that stat proves that for the majority of consumers across the country, the message about using energy efficient lighting has yet to sink in. The upside is that there is a huge potential for energy savings that has yet to be tapped. The U.S. EPA is working to tap that potential and is hopeful that ENERGY STAR certified LEDs will be the centerpiece of a dramatic change in the lighting market.

Last Earth Day, EPA issued a bold challenge to its partners: Sell 20 million ENERGY STAR certified LEDs by Earth Day 2014, and help show your customers how to save energy, save money and prevent climate change with their lighting choices. Retailers from across the country joined in, including Ace Hardware, Best Buy, Costco, Lowe’s and The Home Depot.

They took the charge and have made educating their customers about the benefits of ENERGY STAR certified LEDs a priority in their stores across the nation. And these retailers are stocking and promoting ENERGY STAR certified LED bulbs for a reason–only bulbs with the ENERGY STAR are independently certified, undergoing extensive testing to assure they perform as promised, overcoming the traditional challenges associated with LED lighting.

The combination of high quality and rapidly declining prices (as low as $5 a bulb in some stores) has led to over 10 million bulbs being sold so far in the challenge, and momentum is gaining as we approach the Earth Day 2014 culmination.

So, have you tried an ENERGY STAR certified LED in your home yet? Here are the top seven reasons now is the time.

1.)    Energy Savings: ENERGY STAR certified LED bulbs use 70-90% less energy than a standard incandescent bulb.

2.)    Money Savings: A single ENERGY STAR certified LED can save more than $135 in electricity costs over its lifetime.

3.)    Affordability: The prices for ENERGY STAR certified LEDs are dropping big time—as low as $5 per bulb with in-store rebates.

4.)    Long Lasting: ENERGY STAR certified LED bulbs now look and light more like traditional bulbs, but can last 25 times longer—over 20 years total with typical use.

5.)    Quality and Performance: An ENERGY STAR certified bulb will give you the best LED experience. Only bulbs with the ENERGY STAR are independently certified, undergoing extensive testing to assure that they perform as promised.  To earn the ENERGY STAR, these bulbs must demonstrate that they will meet consumer expectations by delivering on brightness and producing light in all directions.

6.)    Peace of Mind: ENERGY STAR certified LED bulbs carry a three-year warranty.

7.)    Environmental Protection: By replacing 20 million traditional incandescent bulbs with ENERGY STAR certified LEDs, this country would save more than $118 million each year in energy costs, and prevent greenhouse gas emissions equivalent to that of more than 150,000 vehicles.

Believe it or not, most people spend more to light their home than to operate their refrigerator, dishwasher, and laundry equipment combined! That little fact should make it pretty clear why your lighting choices matter. Try an ENERGY STAR certified LED today, and tell us about your experience on our website. We will showcase your stories on ENERGY STAR’s Facebook and Twitter pages this spring.

How Does Data Center Energy Efficiency Affect Me?

2014 February 12

Data center pic

 

By: RJ Meyers

Before I started working  with EPA’s ENERGY STAR program, I honestly had very little idea how much internet connected devices like laptops, smart phones, tablets, and smart TVs used data centers.  Most web services, such as banking, online gaming, movie streaming, corporate websites, and social networking, are hosted in data centers that range in size from a small side room/closet to sprawling multi-million square foot complexes.  These facilities all contain varying amounts and types of IT equipment, as well as the power and cooling infrastructure needed to keep it all running.  They form a sort of “behind-the-scenes” infrastructure for your computer, performing work at some remote location in response to what you’re doing at home, in the office, or on your phone.

When combined, the electricity consumption of all the data centers in the U.S. amounts to somewhere between 2 and 3% of the total grid.  While that may sound small, it helps to remember that the U.S. grid is huge and 2 or 3% of a huge number is still very large—this works out to nearly 300 kWh of energy per person per year, or approximately six times the annual energy consumption of the average laptop1.

Inefficient data centers cost more in their day-to-day operations, since they are consuming and paying for extra energy to perform their services.  Less efficient equipment will also tend to run hotter and require more energy from cooling systems to keep from overheating.   Inefficient data centers also require more physical space between components to keep temperatures down.  All of these extra operating costs may be passed on to clients and ultimately on to everyone who uses their services (i.e., you and me!).

Higher efficiency simply means that you get more for less.  And “less” doesn’t just involve money.  Since the U.S. electrical grid depends heavily on fossil fuels, it also means fewer emissions of greenhouse gases and other harmful pollutants such as mercury.  Power plant emissions lower air and water quality and can affect your health; plus they contribute to the acceleration of climate change.  Reducing emissions through efficiency measures will lead to cleaner air and water, better health, and reduce future damage from climate change.

Please note that while data centers consume lots of energy without your knowledge, they can also be used to avoid other even more consumptive and inefficient activities.  Holding a video conference at work or talking to someone across the country through an internet video chat service consumes far less energy and far fewer pollutants are emitted than flying there to meet in person.  It’s also more efficient to bank online than to drive to the bank in person, or to download a computer game or stream a movie than to go buy/rent a physical copy at the store.

There have been some great strides in IT energy efficiency in recent years, much of it pushed by increasing demand for services and the need to put more and more computing power into smaller and smaller spaces.  ENERGY STAR is proud to recognize and promote high efficiency IT products for data centers and to provide accurate information to data center operators as they look for ways to keep cooling and electricity costs to a minimum.  Doing so helps everyone reduce the impact of their IT infrastructure while improving the online services that we’ve all come to appreciate.

If you would like to learn more about ENERGY STAR certified Data Centers, please head to our website for more information.

ENERGY STAR’s Top Tips to Save Energy This Winter

2014 January 8

Girl in Winter Hat

By: Brittney Gordon-Williams

Did you know that the average family spends $2000 on utility bills each year, and nearly half of that amount goes to heating and cooling your home? With the temperature dipping to dangerously low levels in many parts of the country, this is prime time to make sure that your home is ready for the cold temperatures ahead. Check out these energy saving tips from the experts at the U.S. EPA’s ENERGY STAR program, and get ready to enjoy winter in energy efficient comfort. 

ENERGY STAR’s Top Eight Tips to Save Energy this Winter 

1.)    Use a programmable thermostat: Program your thermostat to match your schedule. To maximize savings without sacrificing comfort, program the thermostat to lower the heat by 8 degrees Fahrenheit or more when you’re away from home or asleep, and you can save about $180 per year.

2.)    Seal leaks and insulate: Hidden gaps and cracks in a home can add up to as much airflow as an open window and cause your heating system to work harder and use more energy. Sealing and insulating can improve your home “envelope”—the outer walls, ceiling, windows and floors—which will make your home more comfortable and improve the efficiency of your heating system by as much as 20 percent. You can save up to $200 a year by sealing and insulating with ENERGY STAR.

3.)    Keep your air filters clean: Check your heating and cooling system’s air filter every month. If the filter looks dirty, change it. At minimum, change the filter every three months. This simple change will help your system work at maximum efficiency—lowering your energy bills and helping your family maintain better indoor air quality.

4.)    Tune up your HVAC equipment yearly: Just as a tune-up for your car can improve your gas mileage, a yearly tune-up of your heating and cooling system can improve efficiency and comfort. Learn more here.

5.)    Install a door sweep: Door sweeps–or weather stops for garage doors–seal the gap between the bottom of the door and threshold, preventing cold air from coming in and warm air from escaping.

6.)    Close your fireplace damper: Fireplace dampers eliminate drafts by sealing your fireplace shut when you’re not using it. Consider using a fireplace “balloon” to make the seal even tighter.

7.)    Change a Light: With shorter days and longer nights, many families will turn on more lighting at this time of year. Select ENERGY STAR certified lighting for bulbs that use 75 percent less energy than a standard incandescent and last 10 times longer.

8.)    Look for the ENERGY STAR: If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC contractor. If it is not performing efficiently or needs upgrading, consider replacing it with a unit that has earned the ENERGY STAR. Depending on where you live, replacing your old heating and cooling system with ENERGY STAR certified equipment can cut your annual energy bill by nearly $200.

Big News about Small Devices

2013 December 16

small network equipment

By: Una Song

Way back when I used to get a newspaper delivered to my door every morning, and would read it with my morning coffee.  Now, instead of opening up the paper, I open up my computer and read the news online. But, have you ever paused to think about what it takes to bring you the paragraphs you are currently reading?  In this age of constant connectedness, many people (including me), take access to the internet for granted. But there is a whole network of devices working together to bring you the words you are reading at this very moment. And now, those devices can earn the ENERGY STAR and help save you money, save energy and protect the climate.

When surfing the web, people usually don’t think about the cable and DSL modems, integrated access devices, routers, switches, wireless access points – collectively known as small network equipment (SNE) — needed to connect us the internet and to other devices in our homes. That is, unless they stop working.  According to market research firm Infonetics, close to 57 million SNE products were shipped in North America in 2013.  Most SNE devices are left on all the time and tend to use the same amount of energy, regardless of network activity level.  If that sounds like a lot of wasted energy, you are right—it’s like having your oven constantly set at 350 degrees.

The good news is that the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR program has recently completed a set of performance requirements that will allow these products to earn the ENERGY STAR, and help consumers identify models that are more energy efficient than the rest.  The next time you need a new modem or router, look for the ENERGY STAR.  If your networking equipment is supplied by your internet service provider, ask them if they will supply you with an ENERGY STAR certified one.  That one move will keep you connected and help prevent climate change. Just think–if all small network equipment sold in the United States were ENERGY STAR certified, the energy cost savings would grow to more than $590 million each year and more than 7 billion pounds of annual greenhouse gas emissions would be prevented, equivalent to the emissions from nearly 730,000 vehicles. These devices may be small, but they can make a big difference for the future of our environment.

Do 1 Thing ENERGY STAR: Find the Savings Under Your Feet by Sealing and Insulating Your Basement or Crawlspace

2013 November 25

 

Basement and Crawl Space

By: Doug Anderson

This week EPA invites you to “Do 1 Thing ENERGY STAR,” by sealing and insulating your home. This blog post is the fifth in a five part series from ENERGY STAR’s home envelope expert Doug Anderson about the benefits of sealing and insulating your home, and how you can get started this fall.

In the last two blogs, I talked about taking steps to seal and insulate your attic to get your home ready for the winter. Second to the attic, the next best way to prepare for chilly winter weather and start saving energy is by sealing and insulating your basement or crawlspace.

Deciding whether to do it yourself or hire a contractor

If your basement or crawlspace is accessible and not too difficult to move around in, this may be a good do-it-yourself (DIY) project. However, it is probably best to call in a professional if your basement or crawlspace has any of these issues:

–       Is wet or damp

–       Has pest infestations (bugs/rodents/snakes)

–       Is very moldy

–       Has strong smells or odors

–       There are loose or dangling ducts/pipes/wires

–       There are foundation problems (such as cracks)

The good news is that there are many qualified contractors that can help you address these issues.

Sealing your basement or crawlspace

If you have decided to make this a DIY project, the first thing to do is inspect your basement or crawlspace for air leaks in common locations. Start sealing any gaps or cracks in exterior walls using long lasting, flexible, indoor/outdoor caulk for any gaps or cracks ¼ inch or less. Larger holes (more than 1/4 inch) in masonry that lead outside can be filled with spray foam-in-a-can and sealed outdoors with masonry caulk or a small amount of cement so the hole is covered and the foam is not exposed to the outdoors.  Chimneys, furnace flues, water heater flues, or dryer flues can all get very hot and require metal flashing and high temperature caulk to properly seal.

Next, seal the rim joist (the wood that sits on top of the foundation wall) as described here, and finish by sealing any remaining holes and cracks to make an airtight space.

Safe Sealing

As mentioned in Blog Post#3, before and after sealing your home, have a heating and cooling technician check your combustion appliances (gas- or oil-fired furnace, water heater, and dryer) for proper venting.  This is called combustion safety testing.  The testing is easy, but should be done by a professional contractor who can sign-off that the systems are working properly.

Also, in certain parts of the country, sealing may trap dangerous indoor air pollutants (like radon) in your home.  Visit the EPA website on radon here for more information.  You can do radon testing yourself for a low cost or hire a professional contractor to conduct tests and discuss solutions if they find problems.  The tests are easy and can give you peace-of-mind.

Additional information on achieving good indoor air quality and proper ventilation in your home can be found here.

Insulating your basement or crawlspace

Insulating basement walls yourself needs to be done carefully and with products that are designed to handle some moisture.  Rigid foam boards and spray foam have been shown to work well for this application because they are less susceptible to moisture issues.  For details on insulating basement walls, visit this technical document for guidance.

Before adding insulation to crawlspaces yourself, you will need to decide whether to insulate the crawlspace ceiling or the crawlspace walls.  Again, in this application it is recommended that you use products that are designed to handle some moisture.  For details on sealing and insulating crawlspace walls check out this technical document  or this technical document for guidance.

Visit the newly updated Seal and Insulate with ENERGY STAR website for more detailed information on how to seal and insulate your basement or crawlspace.

We hope you have enjoyed EPA’s five part series on how to improve your home envelope for the winter. Do 1 Thing ENERGY STAR this week! Start sealing and insulating your home and enjoy comfort and energy savings for years to come!

Do 1 Thing ENERGY STAR: Find More Comfort and Savings by Adding Insulation to Your Attic

2013 November 22

Attic Insulation

By: Doug Anderson

This week EPA invites you to “Do 1 Thing ENERGY STAR,” by sealing and insulating your home. This blog post is the fourth in a five part series from ENERGY STAR’s home envelope expert Doug Anderson about the benefits of sealing and insulating your home, and how you can get started this fall.

In yesterday’s blog, I covered how the attic is typically where the largest energy savings opportunity exists and how to seal air leaks in this area. To complete your attic energy-efficiency improvements, you then need to install additional insulation. By increasing your attic insulation levels, you can save energy and greatly improve the overall comfort of your home.

Attic Insulation: Deciding whether to do it yourself or hire a contractor

If your attic is accessible and not too difficult to move around in, and you enjoy tackling bigger home improvement projects, adding attic insulation may be a good do-it-yourself (DIY) project for you. EPA’s Seal and Insulate with ENERGY STAR program provides great DIY resources to guide you through the process. Even if you are not comfortable taking on this project yourself, there are many qualified contractors who can help you get the work done.

Also, consider consulting a contractor if your attic has wet or damp insulation, moldy or rotted rafters or floor joists, little or no ventilation, or pre-1930 knob and tube wiring. These may require repairs before starting.

Check the Level

Whether you are planning to do the project yourself or hire a contractor, start by checking your attic insulation levels or depth.  All you need is a tape measure or yardstick.  Taking a few pictures of the existing insulation in each direction inside your attic can provide a good record of where you are starting from, so bring a cell phone camera or digital camera with you.

Use the tape measure or yardstick to measure the depth of your existing insulation.  Insulation often varies in depth so check in a few places.  Knowing your current insulation depth will help you determine whether you should add more and how much more you should to add.

Choosing your insulation

Next, choose the right insulation for the job. Rolls of insulation can cover large areas of the attic and are great for wide open rectangular attics. They are available in fiber glass, mineral wool, plastic fibers, and natural fibers, such as cotton.   Loose fill insulation is another common attic insulation made up of loose fibers of cellulose, fiberglass, or mineral wool that can conform to any space, making it ideal for odd shaped or hard to reach locations.

Installing attic insulation

When installing additional insulation, you do not have to use the same type of insulation that currently exists in your attic. You can add loose fill on top of rolls, and vice versa. If you use roll insulation over loose fill, make sure the roll has no paper or foil backing; it needs to be “unfaced.” Rolls installed over existing rolls should be placed side-by-side perpendicularly to the joists to cover the entire space.  Think carefully before you choose this option.  The many rolls you will need can be large to carry back from the store in a small car, and can be difficult to squeeze through small attic hatch openings.

If you choose to add loose fill, it may be wise to hire a professional, as the application requires the use of a blowing machine.  Some home improvement stores offer rentals of this machine for the motivated DIYer.  The machines are heavy and usually require an SUV or pickup to get home.

Keep in mind that insulation can create a fire hazard if it comes into direct contact with places that can get hot, like light fixtures, chimneys or flues, so you should take the proper precautions. Use sheet metal or wire mesh to help create a barrier around them.  Some home improvement stores now sell insulation covers for insulating around recessed lights.
