Rechargeable BatteriesThinking of making the switch to rechargeable batteries? Like other energy efficiency tweaks, rechargeable batteries have an upfront cost, but the long-term benefits are very worth the investment and pay for themselves in just two years. One set of rechargeables can replace hundreds of single-use (disposable) batteries, billions of which are used each year in the US alone. Most of these disposable batteries are not recycled and there is no way to reuse them, making batteries quite the climate mess!

The good news is that rechargeable batteries work great, outperforming regular batteries in most situations (except when used in cameras). Rechargeables also consume up to 23 times fewer natural resources than disposable batteries. Upgrades in technology have allowed rechargeables to become slightly more affordable and better functioning over the years, too. There are now batteries that can be charged using a USB port, eliminating the need for a separate battery recharging station.

Here are some tips to make the switch to rechargeables:

  • Choose high quality batteries to power your life: Here’s a list of the best rechargeable batteries for 2015. Many of the same battery brands you are accustomed to using also offer rechargeables, and there are lots of new companies making great options. Stock up on a few sets, get a charger, and get started with the savings!
  • Don’t forget to charge ‘em up: One of the hassles with rechargeable batteries is that they need to charge, sometimes for a few hours each. Having backup batteries charged and ready to go can help alleviate the stress of an important toy or game that suddenly stops working (doubly important if you have kids who want to play NOW). Many rechargeables also come pre-charged for last-minute needs.
  • Be aware of the power slide: As batteries age, they may not store energy for as long as newer batteries. Rechargables also tend to lose juice as they sit, so charge a batch of batteries every few weeks if you find that you’re running out of power often. If you use a lot of batteries, perhaps keep a few regular batteries around as you get accustomed to regularly charging up your rechargeable stash.

energy-star-logoEnergy efficiency for electronics is a big action that can make a big difference. Natural Resources Defense Council (NRDC) says that the average house has about 25 different electronic gadgets, including televisions, phones, video game consoles, cable boxes, computers, and probably many more if you have little kids! All these gadgets and electronic items consume lots of energy throughout their short lifetimes — including when they are powered off, leading to several billions of dollars of wasted energy yearly.

Here are some actionable tips to help you make your gadgets as efficient as possible:

    • Do your research: Energy Star is a starting place for more efficient gadgets, but it can also be helpful to do some research to find which item is truly the best for your needs.
    • Choose second-hand carefully: Electronic technology evolves so quickly that an item only a few years old could be light-years behind technologically. Compare the energy needs of secondhand televisions, blenders, toys or other gadgets with their newer versions before making the purchase.
    • Be vigilant with the vampires: Even efficient and Energy Star electronics will use juice when they are turned off, so squash the vampire power by using a power strip, a smart strip or simply unplugging all your electronic items when not in use. 
    • Check the charge: Use a watt meter to determine how much energy your item is using, then make adjustments to reduce the flow. Learn about stand-by modes for gaming consoles and other gadgets. Some gadgets (like cell phones) will have built-in energy meters so you can see what’s using the most power. Take advantage of the energy-saving settings, and find hacks to continually reduce your usage.
    • Don’t forget to recycle the goods: At the end of their useful life, gadgets can give back by being recycled. Check out the EPA guidelines for e-waste recycling and read more about why electronics recycling is so important in our blog post.

Here are some more great resources for getting the best bang for your electronics buck:

Keep cozy without your energy $s leaking out the window.

The average American family spends about $1,900 per year on home energy bills. Much of that goes out the window, quite literally. According to the Department of Energy, over half of home energy is wasted in inefficient appliance and under-insulated abodes. On the bright side, most efficiency improvements will pay for themselves quickly, and save you loads of cash in the long run. And there are plenty of free home energy assessment tools out there for owners and renters alike, as well as billions of dollars worth of state and federal incentives.

Heating & cooling make up the largest slices of the home energy pie.

A great place to start is the Home Energy Saver site, which will help you do a detailed home energy audit, then connect up with tax credits, rebates, and financing for efficiency upgrades. There’s also EnergySavers.gov, which has handy tips for greening both your home and your ride. Suggestions range from big investments (replacing windows and adding insulation), to quick fixes that pay for themselves in less than a year (or immediately), like weatherstripping, turning down your water heater, and slashing ~$200 per year off the vampiric tendencies of undead electronics with a power strip diet. If you prefer to be in the hands of a startup instead of government researchers, take a look at WattzOn, which hooks you up with personalized home efficiency and cash incentive suggestions.

Dear Not-So-White House, what’s the R-value of bulletproof glass?

If you want to go the high tech route, you can also take a thermal image of your personal palace with an infrared camera, which will give a stark visual of where heat leaks out while Jack Frost is nipping at your nose (which happen to be the same spots where heat sneaks in during the summertime). As a bonus, renting a thermographic camera will help you investigate paranormal activity, as well as spy on Obama’s R-values.

A vampire lurks in your DVR! (and cable/satellite box too!)

Which appliance consumes the most power in your home? The refrigerator? The washer, dryer, or TV? A quick energy audit will tell you that the culprit may be a much less imposing energy beast, if you (like over 80% of Americans) have a DVR and set-top cable or satellite box. That’s right, those seemingly innocuous glowing little boxes can combine to suck more electricity than an Energy Star refrigerator, according to a study by NRDC.

There are approximately 160 million DVRs and set-top boxes in the US now draining about $3 billion worth of electricity per year, the equivalent of nine 500 MW coal-fired power plants. That’s more power than used by the entire state of Maryland! And the real kicker is that 2/3 of that energy is consumed when these devices are supposedly “off.” Unfortunately, these little buggers never really die: the lights may go off, but they’re still sucking over 90% what they would while on. And that power drain happens 24/7, 365 days a year. Thus, an HD DVR typically consumes more power than the TV it’s connected to.


So the trick-or-treaters may be long gone from your doorstep, but you’ve still got some big energy vampires lurking in the darkness. The good news is that Buffy [the vampire slayer] is now on the way via a new EPA Energy Star 3.0 standard that mandates substantial improvements over the 2.0 version, and the cable industry (which owns most boxes) recently announced voluntary efficiency measures after all the bad press. But the only way to truly curb your boxy vampires’ appetite is to put them on a power strip that you switch off when you’re not watching TV or recording Buffy reruns. Or join the hipster kids and just stream it all online.

LED lighting is getting cheaper, “warmer”, and more efficient. Time to switch?

An offshoot of the semiconductor industry, LED lighting technology is already abundant in our lives, from traffic lights to flat screen TVs and computer displays. That’s because LEDs produce are about 10 times more efficient than conventional incandescent lighting, and they can last up to 100 times longer, equating to substantial energy, cost and eco-impact savings over time.

So is it time to re-illuminate your home sweet home? The downside is that LEDs still aren’t cheap, with standard socket LED bulbs costing anywhere from $5 to over $50. LEDs have also struggled a bit matching the “warm” light put off by incandescents, the same problem faced by compact florescent lamps (CFLs) when they first hit the market. But LED prices are coming down quickly, while both efficiency and light quality are improving. The typical LED is now twice as efficient as a CFL, and takes roughly the same amount of energy to manufacture. LEDs also last 2 to 3 times longer, and they’re better than CFLs at dimming (“dimmable” CFLs still tend to flicker, while LEDs are better at maintaining smooth illumination and color temperature, though some brands still have kinks to work out). LEDs also have a leg up on CFLs in that they don’t contain mercury, a toxic component of all CFLs that subjects users to special recycling and breakage clean-up recommendations.

If you’re ready to dive into the future of light, sites like Amazon are of course awash with LED options. Beyond price, pay close attention to customer ratings, “dimmable” claims (if you need dimming), and color temperature (2,700-3,300 K will match standard incandescent lighting, while higher numbers mean a “cooler” color). The EPA award-winning Light Bulb Finder app is a great way to quickly see how options stack up, and there are a number of fabulous online calculators out there that estimate how LED when investments will payback and start turning a profit (vs. both CFLs and incandescents). When both energy savings and longer bulb life are factored in, replacing an incandescent with a $25 LED should save you at least $150 over the 25-year life of a frequently used LED bulb, and if you’re willing to get a bit more creative with your lighting you can save even more.

A few tips to ensure our world doesn’t come to an end this year.

We’re not really the gloom and doom types, so despite what some apocalypse-happy interpreters of the Maya calendar may say, we’re pretty sure our wonderful world didn’t come to an end in 2012. More likely this 3rd rock from the Sun is sticking around for at least the next 7 billion years, all the more reason to make it a more pleasant place to reside. Resolutions in 2013? We’ve got too many, but (keeping in theme) here are 13 to kick off the new year and round out a baker’s dozen. Unless noted otherwise, numbers below are based on calculations from UC Berkeley.

1) Eat What You Buy, Buy Only What You’ll Eat (or Compost)

The average American family throws away $2,100 worth of (what was once) perfectly delicious food each year, according to NRDC. All that wasted food annually sums to a tremendous amount of wasted resources: 25% of all freshwater, 4% of US oil consumption, $90 billion in economic losses, and 31 million tons of landfill waste (which releases the potent greenhouse gas methane as it degrades). If that moldy can of cranberry sauce has truly transcended the bounds of edibility, toss it in the compost bin instead of the trash (which won’t revive the wasted resources, but will significantly reduce methane emissions).

2) Become a “Weekday Vegetarian”

We’ve written before about how meat makes up the largest part of food’s footprint for most of us. So the less (red) meat (and dairy) you eat, the better your dinner looks for the planet. If you don’t already have vegan tendencies, start with meatless Mondays and work your way up to become a weekday vegetarian, which allows you to eat as omnivorously as you please over the weekend. Besides cutting support for inhumane factory farms, weekday vegetarianism should save you over $1,000 and ~2 tons of CO2 per year.

3) Live Close to Work (&/or Telecommute)

The closer you live to your place of employment the better it is for all of us: you waste less time commuting, save energy, save money, and contribute less to congestion. So live within walking or biking distance of the office, if possible, or scheme up ways to telecommute. If you can’t cut out your fuel-fueled commute entirely, carpooling and public transportation are the next best things. Here are some tips to help you calculate how your options stack up.

4) Bike for Buns of Steel (& a Better Tomorrow)

That’s right, biking is not only the greenest way to roll around town, it’s also great for your gluteus maximus (and pretty much all your other parts, assuming you can avoid agro taxis, rail ruts, and car doors). Who knows, pushing pedals may even inspire you to become the next Danny MacAskill. If not, you’ll at least look less ridiculous than these guys.

5) Take the Pedal Off the Metal

When you do have to drive, try to resist the hot inner Indycar driver. Cutting down on speeding, excess cargo weight, sudden acceleration and deceleration will save both gas money and break pads (and perhaps your life as well). Just reducing highway cruising speeds from 75 to 65 MPH will save the average driver about $500 and 2 tons of CO2 per year. Properly inflating tires and changing air filters can lop off an additional annual savings of $200 and 0.75 tons of CO2.

6) Cash-in That Clunker (for a Fuel-Sipper)

Upgrading from a car that gets 20 MPG to 35 MPG will save the average driver about $750 and nearly 3 tons of CO2 per year. Really want to blow your neighbors’ minds in a cacophony of cognitive dissonance? Try an electric Hummer HX-T. Euro pop techno music apparently comes standard!

7) Cool Water + Warm Sun = Lasting Laundry

Your clothes really don’t need hot (or even warm) water to clean, thanks to the miracles of modern laundry detergent chemistry (including the best biodegradable brands). That’s good, since washing hot means 90% of the energy in a load of laundry goes to heating water. Then there’s the dryer, another major energy hog. Line drying (either outside, or indoors on a rack) saves not only energy and emissions, it also extends the life of your clothing, avoiding up to $70,000 over 30 years (if you believe estimates from The Daily Green).

8) Reduce, Reuse, Recycle

It’s cliche to say, but the less stuff you buy the less of a footprint you leave behind. When you do buy, try to buy reused (Goodwill and Craigslist being great places to start). If you’re not motivated by things like climate change, resource scarcity, and habitat loss for cuddly critters, consider the human cost of making cheap stuff via the Slavery Footprint calculator. Recycling is great too, though many products can only be recycled into lower value materials, so even better to have less to recycle to begin with.

9) Slay Your Energy Vampires

We’ve already warned you that your DVR and satellite/cable box may be sucking more energy than any other appliance in your home (refrigerator included!), even when you think they’re switched off. You may also have plenty of other appliances out there sucking electrons in stand-by mode, adding up to hundreds of dollars of wasted energy. The only real way to stop the energy vampires is by putting everything you can on switchable power strips, which you turn off whenever you’re not putting gizmos to use. There are now even smart strips that cut phantom power to other plugged-in electronics once a controlling device (like a TV or computer) is turned off.

10) Don’t Procrastinate, Insulate (& Go Solar!)

A well-insulated home is a happy home, since over half of home energy use leaks out the cracks. If you really want to upgrade your crib into the green stratosphere, ask your utility about buying green power or put some solar panels on your roof. With prices below $1 per watt, solar PV has never been cheaper, and you can virtually eliminate your home’s carbon footprint with the right set-up. Group buying services like 1BOG can help you get the best deals out there.

11) Put Your Money Where Your Heart Is

If you’re a lucky ducky with a nest egg to hatch, make sure it’s incubating in companies you believe in. We’ve compiled a few tips to help you green your 401(k) portfolio. Give ’em a gander (or a goose, if you prefer).

12) Take a “Staycation”

The more scientists look at aviation impacts, the less friendly flying looks for the planet. It’s not just CO2 emissions from jet engines that are a problem; high altitude NOx, soot and water vapor also directly contribute to global warming, potentially doubling to quadrupling the impacts from CO2 alone. So a roundtrip flight across the US is at least akin to driving a 15 MPG Chevy Suburban all by your lonesome, or worse. Perhaps a staycation is in order instead? Just kick back, relax, catch up on your blog reading, and enjoy the fruits of your post(poned)-apocalyptic resolutions!

13) Kill Your Catalogs

Each year about 19 billion catalogs are mailed in the US, chopping down 53 million trees and guzzeling 56 billion gallons of wastewater to produce piles of paper that mostly go straight to a recycling bin. Go to catalogchoice.org to stop the madness in your mailbox.
