An Assessment of Television’s Environmental Impact: Common Sense Considerations to Reduce Energy Consumption

My life recently shifted—away from friends and family, career, a splendid city, and the life I had built for nearly a decade to the unknown of a new country, city, and job.  With this transition came a new perspective and radical changes that are mostly welcome, sometimes challenging, and always unexpected.  These changes will soon be reflected in my postings.  However, before my departure I finished research on a topic I long avoided due to my lifelong addiction—television.

While my new life means that a television is no longer my low maintenance companion, offering entertainment and the constant hum of background noise, it does not mean that its presence is no longer felt.  Many homes in Thailand have at least one television.  In the country I left, the numbers are staggering.  The U.S. is home to almost as many televisions as people—approximately 275 million televisions live in our homes and offices.  

We are a culture that loves its TV.  I am no exception.  But what are the costs of our devotion to small screen entertainment?  What are the ecological impacts of our televisions and viewing habits?

The Creation, Life, and Disposal of Televisions

There are three stages in the "life" of a TV that create environmental impacts. These are (1) manufacturing and transport; (2) use; and (3) disposal

(1) Manufacturing and transport

Making a television is an energy intensive industrial process. This process requires fossil fuels to provide the considerable amounts of energy necessary to manufacture the highly refined glass and semiconductor components that make up modern television sets.  These components are comprised of non-renewable materials that contribute to the increasing problem of electronic waste

Once a television is manufactured, it must then be packaged and transported to its point of sale.  Some large retailers have made efforts to reduce their ecological footprint vis-a-vie transport (Sony, for example, now has a policy of shipping its goods by rail or sea rather than truck or air to reduce its energy costs).  Others have incorporated transport concerns into the CSR or corporate social responsibility programs.  However, while some CSR programs are effective, others should be viewed with skepticism and employ more rhetoric than actual corporate accountability. 

(2) Use

The environmental impact of your television will vary based on the type of television you own and how often you watch it.  Old-fashioned televisions use cathode ray tubes (CRT), which require more electricity than televisions based on newer technologies.  Yet new technology does not necessarily mean smaller carbon footprint.  Plasma televisions ionize gas to create the colors needed for its pixel cells, and this process requires significant amounts of energy to brighten the screen. 

Currently, the best choice for energy consumption is a flat-panel liquid crystal display, or LCD.  LCDs use fluorescent backlighting, which draws less energy than traditional technologies.  LCD technology has also advanced so that the backlighting is only on for certain areas of the screen or as needed, an improvement on earlier models that required backlighting to be constantly on full. 

An emerging technology that offers further energy reductions are sets using organic light emitting diodes or OLEDs.  OLEDs use an array of small LED lights in a very thin screen, promising to double energy efficiency from the best available current technologies. 

Size also matters.  Larger screens and longer duration of use increase energy use.  Standby or vampire power further increases energy drawn from TVs (see previous livingneutral post on how to reduce standby power usage).  Even when a television is off, it is not completely shutdown and still requires power to remain on standby.  There are ways to reduce our standby power consumption, or eliminate it entirely, which are discussed in a previous entry. 

Manufacturers are also mindful of this issue, working to improve efficiency to stay in line with energy star ratings in countries like the US and Japan.  Choosing a certified energy efficiency model will ensure that these kinds of considerations went into the design of your television.  If possible, try to find a manufacturer that complies with ROHS, or the European Reduction of Hazardous Substances directive. The ROHS requires the elimination of hazardous substances like lead and mercury in electronics imported into EU member states.  Because the US does not have similar restrictions, many available electronics still contain lead-based solder, mercury, cadmium, and brominated fire retardants.  Manufacturing with these chemicals creates toxic waste and emissions and pollutes disposal sites.

Broadcast power further contributes to TV’s broader environmental impact.  Transmission of broadcasts signals requires large amounts of power.  Alternatively, programs downloaded via the internet require much less energy on the front end to reach your screen.

(3) Disposal

Even at the end of its life cycle, a television continues to impact the environment.  According to the EPA, approximately 20 million televisions are disposed of in the US annually, with more than 80 percent going to landfills.  Toxic chemicals from these TVs can leach into soil and groundwater, creating environmental and health hazards.  Recycling offers a promising alternative.  However, it is important to understand where the television goes when recycled.  Often, they are resold in developing countries.  CRT tubes can also be melted down to make products like car batteries.  This often occurs in countries where environmental regulations are non-existent or go unenforced. 

In summary—if you are in the market for a television, consider an energy efficient model that complies with international standards.  Letting go of your need for a massive screen will also lower your energy bill and ecological impact.  Finally, try to use a television for its full life cycle, and do not simply discard it into a landfill once its reached expiration date. 

With recent news that we’ve passed the 400 parts per million carbon dioxide milestone, it is important that we begin to make changes in our lives.  These might be radical—giving up the use of a television entirely as I have—or small—using energy efficient models for the duration of their lifespan.  We owe our future selves and generations the foresight to make better decisions today.  Indeed, our choices should be obligations—to reduce our ecological impacts and encourage businesses through our behavior.

Green Holiday Habits: Tips for an Eco-Friendly Holiday Season

An inundation of Christmas music and gift advertisements, a series of food comas, and invitations to ugly sweater parties can only mean one thing—it’s holiday season again.  It’s a time to celebrate with family and friends, to show gratitude, and make plans for the coming year.  The holidays also mean gifts, cards, wrapping paper, lights, Christmas trees, parties and travel. These material things impact our environment.  At the risk of sounding like Scrooge, here are a few suggestions to cut down on your holiday eco-footprint.   

Reduce Your Paper Use

1.  Holiday Greeting Cards

A staggering 1.5-1.9 billion holiday greeting cards are sent in the U.S. each year.  The impact of this volume of paper, combined with packaging and the transportation costs to deliver these cards, adds up quickly.  Paper waste accounts for 40% of the contents of our landfills. The paper products industry is the third largest source of green house gases, behind petrochemical and cement manufacturing.

The alternative to paper cards is simple, cheaper, and more environmentally sound: email.  For those concerned with etiquette, Huffington Post's Ms. Eco Etiquette and the Post family agree that e-cards are the greener, logical alternative to paper holiday cards.  E-cards, once a bit garish and obnoxious, now come in a number of attractive and witty forms.  Paperless post is an excellent example.  Another email option that I always enjoy receiving are holiday email updates from family and friends. This can come in the form of a recap of the year and often includes photos and other personal flourishes. 

Emails do have an eco-footprint, albeit much smaller than paper.  An email has 1/60th the carbon footprint of a traditional letter.  Still, our virtual impacts add up: internet use accounts for 3% of U.S. energy consumption

For those who just can't let go of the tangible card option, consider purchasing recycled cards or buy form local card makers.  Miss Eco Etiquette also suggests Botanical PaperWorks, cards made of 100% post-consumer waste that include plantable wildflower seeds.  A recycled card that grows into a beautiful plant—what could be greener?!  If you receive greeting cards, try to reuse them.  Recycled cards make excellent gift tags, postcards, and bookmarks. 

2.  Wrapping Paper

In addition to the large amount of paper consumed through holiday cards, wrapping papers' near ubiquitous use—an estimated 98% of consumers claim that they will wrap presents for the holidays—contributes to the large volume of holiday paper waste.  Nearly half of the timber harvested makes its way into paper products, and paper requires more water than any other industrial activity in developed countries.  Between Thanksgiving and New Years, Americans dispose of a million extra tons of trash a week.  That’s 25% more waste than the rest of the year.  Half of the paper products we consume goes towards packaging, wrapping and decorating products (with wrapping paper and shopping bags accounting for 4 million tons of trash annually). 

Instead of wrapping gifts in new paper, try to reuse other gift bags or paper and recycle or reuse any paper from gifts you unwrap.  Note, however that most conventional giftwrap is not recyclable.  Tape also complicates the process: it isn’t biodegradable or recyclable.  By wrapping three gifts in recycled paper, we could save a collective 4.5 million yards of paper Boxes can also be reused, and look for “tree-free” giftwrap made from bamboo, hemp, or cotton.  Newspaper, fabrics, shopping bags, and even cereal boxes can also be repurposed as giftwrap.

3.     Gift tags and invitations

The same suggestions apply to gift tags and party invitations. Try a DIY option, think about reusing household items (file folders, old cards, etc), send e-invites, and be creative!

Lessen Your Electricity Load

If you must decorate your house with lights, upgrade to LED lights, which use 90% less energy than conventional lights.  This can also save you $50 a month on your energy bills.  The U.S. Department of Energy estimates that if everyone replaced their conventional holiday lights with LED lights, we could save 2 billion kilowatt hours of electricity each month.  Switching to smaller bulbs also reduces energy consumption. 

Another simple energy-saving solution is to simply turn lights off.  When you are not home or asleep, there is no need to illuminate an unseen room or space. 

Be Tree Friendly

Christmas trees are a must in many households. Of course, there are fir-free alternatives.  These, however, require energy and materials to manufacture and supply, although the one-time purchase of a fake tree can save energy.

If you, like many, want a live tree and the pine smell it brings, then at a minimum recycle your tree as soon as possible.  Fresh trees can be ground into woodchips rather than taking up space in a landfill.  Earth 911 provides further info for tree recycling in your area.  

And . . . a few miscellaneous things.

Consider donations in lieu of gifts or buy local.  Look for organic, sustainable foods and try to keep your portions and leftovers minimal.  Making a few changes can ensure happy holidays for generations to come.  Be well and enjoy!

Greening Your Laundry Habits Part II: Natural Alternatives and Efficient Products

photo credit Jefferson Sisters blog

The environmental impact of laundry is considerable.  In fact, between 75 to 80 percent of the lifecycle of our clothing comes from its washing and drying.  Fortunately, there are a number of alternatives to conventional laundry habits that can significantly reduce your laundry’s eco-footprint.  In addition to reducing the temperature of the water used while washing, as discussed in my last post, ecological impact can be reduced by line drying, purchasing concentrated and eco-friendly laundry detergents, and being smart about the kind of appliances we purchase and use.

Reduce Dryer Use, or Better Yet Line Dry

The dryer uses enormous amounts of energy.  It ranks second in energy use for household appliances, right after the fridge, and accounts for approximately 6% of home energy consumption In the U.S. alone, there are an estimated 88 million dryers, each emitting more than a ton of carbon dioxide a year.  On average, this also adds over $70 to your annual energy bill. 

You can save energy, lower your utility bills, and improve your ecological footprint by simply reducing your use of the dryer.  Try line drying all or part of your laundry.  Like washing with cold water, line drying is better for your clothes and increases their longevity.  There are excellent resources that provide tips for line drying, including how to avoid clothes becoming too stiff and products that make line drying easy.

Eco-Friendly Laundry Detergent

Conventional household cleaning products, including laundry detergents, often contain ingredients that are toxic to the environment and human health.  Phosphates—found in some laundry detergents—can wreak havoc downstream on marine life and aquatic habitats.  Fortunately, there are a number of alternatives that are phosphate free and biodegradable.  Look for a detergent that has plant or vegetable derivates rather than being petroleum based. 

In addition to being eco-friendly, your detergent should also be super concentrated.  These detergents come in smaller bottles, which means less packaging and reduced transportation costs (fuel, air impacts, etc).  I use method’s Lighthouse, which is eight times more concentrated than traditional detergents.  There are other concentrated detergents, and the trend towards soaps that contain less liquid is on the rise.  Most of these detergents can be used in cold water cycles, which as we have learned dramatically reduces energy use. 

For the do-it-yourself crowd, making your own laundry detergent is an option—and several sources provide recipes and instructions.  Fabric softeners also should be avoided.  Instead, trying adding a cup of white vinegar during the rinse cycle, which naturally balances the pH of the soap and leaves clothes feeling soft. 

Maximize the Efficiency of Your Appliances

The kind of washer and dryer you use is also a factor in the environmental impact of your laundry.  For example, switching to an Energy Star washer reduces energy use by 50% and can save up to 7,000 gallons of water each year.  Treehugger estimates that over an 11-year lifecycle, that is enough water to provide a lifetime supply of drinking water for six people.

Your dryer choice also matters.  If you can’t live without a dryer, use one with a moisture sensor to optimize efficiency.  Clean out the lint filter after every use, which will improve the performance of the dryer.  Like fabric softeners, avoid dryer sheets if possible.  They contain toxic chemicals and actually wear out fabrics

The proper load size is also important for a machine’s efficiency.  Small loads waste water and fail to maximize a washer or dryer’s space.  Conversely, large loads are hard on the machine’s motors, which lead to energy inefficiencies.

Finally, the carbon neutral fanatic can always use a handcrank clothing washer, which reduces energy use—aside from your own—to virtually nothing.

Greening Your Laundry Habits: Tips to Reduce the Impact of Washing Machines

Laundry is one of those household tasks I try not to think too much about.  Often tedious, never inspiring, laundry is relegated to my must do but actively avoid checklists.   Yet this single task accounts for about 14% of our household water use and has a heavy impact on our carbon footprint.  What accounts for the large energy and environmental costs of washing our clothes?  How can we reduce the impacts of the estimated 400 loads of laundry the average American household does each year?

There are several simple solutions that can dramatically cut your water and energy use, and reduce your laundry’s footprint.  These include adjusting the temperature of your wash, reducing dryer use, maximizing your appliances, and using more concentrated green laundry detergents.  This post will tackle the first of these issues, with follow-up on the remaining laundry strategies to come.

Turn the Temperature Down: Wash in Cold Water

Nearly 90% of the energy used to wash clothing goes to heating the water.  This energy use has monetary and environmental implications: a single load of laundry washed in hot water is equivalent to driving nine miles in an automobile.  It also adds over $100 annually to your utility bill.

The simplest solution to this energy problem: reduce the temperature of your wash cycle.  Switching to warm water will cut a load’s energy use in half.  Washing in cold water is even better—it is estimated that if Americans switched to washing in cold water rather than hot, we could reduce our national carbon emissions by 1% and save over $3 billion dollars in energy costs.  Cold water is also better for your clothes.  Hot water reduces fabric longevity and speeds up color fading. 

Furthermore, washing with hot water is often unnecessary.  Washing machines are more advanced and efficient than years past when hot water washing was the default.  There are also many effective, ecologically sound laundry detergents that are formulated for cold water washing (including for whites and stains).  In light of these product advancements, there is simply no reason not to wash your clothes in cold water.  Unless there is a particular reason, such as allergy prevention or oil stains, each load of laundry done in hot water wastes energy.

Finally, be sure to set your hot water heater to no higher than 120 degrees and try to minimize water use.  This may mean wearing clothes more than once before washing or shortening your wash cycle.  For example, the UN Environment Programme estimates that if you wear a pair of jeans at least three times and wash in cold water, you consume five times less energy than washing after each use.  These changes are crucial.  Water is and will continue to become a valuable resource, with demands for clean, reliable sources increasing.

The Carbon Pawprint of Pets: 3 Considerations for Green Pet Care 

Are you a dog or cat person?  Perhaps, like me, you consider yourself both.  Regardless of your preference, it is likely that you—like the majority of Americans—are an animal lover in one form or another.  According to a recent survey, more than 71 percent of U.S. homes include a pet.  Dogs are more popular than cats—with over 45 percent of households owning at least one dog, and roughly 38 percent owning at least one cat. 

Our pet culture is evident everywhere—in neighborhoods and parks, in advertisements, even in fashion and pop-culture.  However, the environmental impact of our furry friends is something given little attention.  Frankly, it was something I hadn’t even considered when beginning this journey to reduce my ecological footprint.  The impact, according to two New Zealand scientists, is large and startling.  Robert and Brenda Vale’s book, “Time to Eat Dog?  The Real Guide to Sustainable Living”, claims that dogs are worse for the environment than SUVs.  According to the Vales’ research, a medium-sized dog has double the impact (and carbon footprint) of driving an SUV 10,000 miles.  Cats fare a bit better, with the impact of a Smart Car, and gold fish have impacts equivalent to two cell phones.  This hierarchy makes sense—the smaller the animal, the smaller its environmental impact.

Why are dogs and cats so bad for the environment?  These animals are carnivores, and it takes a lot of carbon-producing land and energy to make their food.  However, this does not mean that we should do away with domesticated animals.  Pets provide many other benefits—including companionship—and like other environmental impacts can be improved by making a few simple changes.

Greening Your Pet Care:

1.     Reduce Your Pets’ Food Impact

Because our pets’ biggest impacts come from their food, this should be the focus of any meaningful change.  Dogs—unlike humans—typically eat food made mainly of beef or beef by-products.  Beef has the worst environmental impact of all meats.  Fortunately, there are alternatives—the best being to make your own pet food from other proteins and vegetable sources.  This solution has the benefit of cutting down on processing and transportation impacts and allows you to make the same kind of food choices for your pet as you make for yourself (local sources, healthier options, etc).

If you are unable or unmotivated to make your own pet food, consider how pet food is produced.  Select smaller, locally made pet food brands or buy in bulk.  Look for foods with non-beef ingredients, like chicken, fish, and duck.  Organic food and treats are also readily available and often a better option.  Our pets, like us, need to have a balanced healthy diet to ensure a long life a lower risk of chronic health issues.

2.     Use Environmentally Friendly Products

As with other products we purchase, look for options that decompose and at a minimum don’t pollute.  Opt for compostable bags for your dogs waste.  Replace traditional cat litter—which is bad for your cat’s health—with ones made out of recycled newspaper or corn.  Select animal shampoos that are free of unnatural chemicals including sodium lauryl sulfate.  Most of these products are available at local health food stores or online. 

Flea and tick treatment often contains chemicals that are dangerous to both human and animal health.  For safer alternatives, check out NRDC’s list or consider making your own natural solution.  One vet suggests a flea treatment made with a base of castile soap and additions of 10 drops of lavender, five drops of eucalyptus, five drops of rosemary, and five drops of cajuput oil.  Feeding your dog garlic rosemary treats is also a preventative flea treatment.  

3.     Invest in Recycled and Reusable Products

Like accessories and toys for people, there is a wide-range of products available for your pet.  Instead of repeatedly buying cheaper, lower-quality pet toys that end up more frequently in the landfill, invest in higher quality, durable products.  There are many products made from natural materials—like hemp, soy, and organic cotton—that don’t contain chemicals and are built to last.  Hemp leashes and collars are also more comfortable for dogs than their nylon counterparts and can be washed and reused with ease. 

As with food and flea remedies, consider making your own toys and accessories by reusing materials or products you have at home (used tennis balls, fabric or old blankets for bedding, etc).  An old suitcase and some fabric can be turned into a small bed for your dog or cat. 

Making a few of these changes can make a big difference in your pet’s environmental impact and their overall health.  You can also consider changing some of your own habits to offset the impact of your pet.  These changes can ensure that the benefits your pet provides will far outweigh their ecological impact.
