Light Bulb 101

Energy Efficient Light Bulbs 101 – At Home

Confused by which light bulb to buy? We’ve put together a short primer to (ahem!) “shine some light” on the topic for you.

Here’s the key thing to know about light bulbs. If you buy junk, you’ll get junk. 

Quick facts:

  • It used to be that wattage of the bulb determined what you needed to buy. Not so much anymore. Lumens is what you should look for. The higher the lumens, the more light is output by the bulb.
  • Be wary of really cheap LEDs. More than likely they don’t last very long. LEDs are supposed to last well around 20 years. Cheap ones typically last for less than 10 years.
  • Only buy bulbs with an ENERGY STAR logo on them. This is the only way to know if a light bulb is truly a good purchase. In order to receive the ENERGY STAR logo, they can’t just save energy. They must be up to 90% more efficient than standard bulbs, last at least 15 times longer and save about $55 in electricity costs over their lifetime, meet strict quality and efficiency standards that are tested by accredited labs and certified by a third party, and produce about 70-90% less heat (safer to operate and can cut energy costs associated with home cooling). This is why cheap LEDs, which save energy, cannot get the ENERGY STAR logo.

So let’s get started!

Incandescent Bulbs:  These are what I call the “old-fashioned” bulbs though they are becoming less standard all the time.


Pros: They create warm light. They are also inexpensive to purchase.

Cons: They wear out quickly, use more energy, and create more heat. That means more frequent replacement (may outweigh the low sticker price) and more energy use.

Life: 800 – 1,000 hours

Cost per bulb: ~ $1 per bulb

Dimmable: Yes

Energy used: ~.06 Kilowatts (kW)

CFL (Compact Fluorescent Lights) Bulbs: The second generation to the humming tubes hanging in your dad’s basement workshop, these are the curly-shaped little darlings.

When we first moved away from incandescent bulbs, critics of the CFL cried ugly because they produced a cool, harsh, light with blue undertones. As technology has advanced, CFLs can be found in warmer color spectrums that are closer to the traditional incandescents.

Pros: CFLs use 75% less energy than incandescent bulbs. They also produce less heat than their incandescent counterparts (approximately half, depending on the bulb).

Cons: CFLs contain mercury. They are more expensive than standard incandescent bulbs and are arguably less attractive. Designers will not select this bulb.

Life: 6,000 – 15,000 hours

Cost per bulb: ~ $2 per bulb

Dimmable: No (dimmable options may be available for purchase)

Energy Used: ~.014 Kilowatts (kW)


LED (Light Emitting Diode): The energy superstars of the group. Depending on the brand and variety, they can last from 2 – 25 years. Put them in your teenagers’ bedrooms. You know they’re not switching them off.

Pros: LED bulbs produce less heat and last a long time. New LED bulbs can cast that warm-colored light we love. LEDs don’t break when jostled, a huge factor in busy manufacturing sites and industrial areas. Best of all, they don’t contain mercury.

Cons: LED technology is moving quickly.  Some of these bulbs still create directional light, but most newer versions disperse light better.  Lastly, LEDs do have a slightly higher upfront cost.

Life: 50,000 hours

Cost per bulb: ~$1.25 – ~$20

Dimmable: Yes (non dimmable options are available)

Energy used: ~.008 Kilowatts (kW)

Sustainable Efforts for Light Bulbs:

  • Place your lights on a dimmer. It can save up to 50% in energy costs. Remember, most CFLs and even some LEDs aren’t dimmable. You’ll need to look for and specifically buy dimmable bulbs.
  • Turn out the lights: One incandescent bulb left on 8 hours costs ~ 6 cents. 5 incandescents burning 8 hours cost ~ 30 cents which equates to $110/year. 2 porch lights, 1 kitchen light, 1 family room light, and 1 bathroom light burning. These costs can start to add up quickly.
  • Recycle:  CFLs contain mercury and all bulbs take up space in landfills. The good news is it’s easy to recycle your old bulbs. You can even bring them to your neighborhood hardware stores. Visit this site http://search.earth911.com/ and type in your zip code for recyclers near you

Conclusion:

  • Try to buy LEDs everywhere you can, but if you can’t, target your high use areas first! If you have incandescents, go ahead and replace them. If you have CFLs, wait until they die, and then upgrade.
  • LEDs have gotten extremely cheap! Off brand is perfectly fine to buy, as long as they have the ENERGY STAR logo.
  • Make sure to match lumens, not watts. Take your old bulbs with you to the store and look for the LEDs that have close to the same lumens, not watts. You may have a 60 watt incandescent only to find a 40 watt ‘equivalent’ LED is actually what you need.

Energy Efficiency: Georgia Power vs. Alabama Power

You might think that there isn’t much difference between the utilities within each state’s borders (I know I didn’t). We give them money, and in return they make sure we have working electricity. Seems simple enough, right? How much more could there be?

As you may have guessed since this is an article and not a single paragraph, there’s a lot more to it than that. But, rather than compare every single utility within each state, we’ll focus on the differences between Georgia Power and Alabama Power which are both owned by Southern Company.

Specifically, we want to examine the differences in terms of how much money each company spent on energy efficiency compared to how much energy they are saving through those programs. But first, a little background information.

Each year, most utilities spend money that is supposed to go towards incentive programs that help customers save energy.¹ Most utilities channel a portion of the money that we pay them into energy efficiency programs, often being forced to do so by regulators because they don’t normally like selling less of their product. These programs exist to incentivize consumers to make upgrades on their homes and businesses, which is much cheaper than building a new power plant.

But not all utility energy efficiency is created equal and we have to take a look at the reality on the ground.

As of 2019, Georgia Power spent $16.5 million dollars, through various programs, on residential customers if they invested in cleaner energy efficiency for their homes. For commercial customers, Georgia Power spent $24.8 million dollars on energy efficiency. With that money, residential customers saved 95,124 megawatt hours (MWh), while commercial customers saved 295,968 MWh. That’s a total of 391,092 MWhs saved in 2019 alone! For comparison’s sake, the average Alabama home uses between 1 and 2 MWh per month.

Since Georgia Power and Alabama Power are owned by the same parent company, wouldn’t it make sense for Alabama Power to offer similar opportunities to their customers? Sadly, neither Alabama Power, nor Alabama regulators, seem to think so.

Unlike Georgia Power, Alabama Power only spent about $3.3 million dollars (of which just ~$5,000 were for incentives) on residential energy efficiency, and $84,000 for commercial customers. With that paltry sum, residential customers only saved 5,486 MWh and commercial customers just 192 MWh.

Why does Georgia Power spend so much more than Alabama Power? The price that consumers pay each company is fairly similar. So what’s going on here?

It comes down to monopoly control. Utilities do not want you to save energy, they want you to buy energy from them. It is the job of the regulators at the public service commission to protect consumers from monopoly abuses. Some regulators force utilities to invest in lower-cost energy efficiency since a monopoly would not do so on its own. Some regulators have even gone so far as to change the way utilities are paid in order to give the utilities a financial incentive to promote energy efficiency. Neither of those things happen in Alabama.

Part of it is that Alabama Power wants to build power plants, because they earn profit from how much new construction they do, regardless of if the construction is needed. In order to justify new construction, they need you to use more energy, not less. Don’t forget that Alabama Power customers are now on the hook for more than $1 billion in new gas plants…

I digress. The point is that we are giving utilities an arm and a leg, but we aren’t getting out what we put in. We’re already paying enough on our utilities bills to work towards the future and switch over to clean energy. Georgia, though they’ve just begun, has the right idea, and even they are behind the curve compared to many other areas of the country. So why is Alabama Power falling further behind? And why are we letting them get away with it?

Why Your Utility Bill Is So High (And What to Do About It)

It’s wintertime, and let’s face it: Your utility bill is going to be high this time of year. Even so, you might still be frustrated with your utility company when you get a bill that’s three or four times higher than normal. But before you call up your provider and give them a piece of your mind, see if this scenario sounds familiar.

OK, so you just checked the thermostat. It’s 12 degrees outside. Twelve! Meanwhile, you’re freezing inside your house because you’ve lowered your thermostat all the way to 66. You’re covered with blankets. You’re doing your best to save energy and… your bill is still crazy high.

Right, we get it. Us too. First things first: No, your utility company hasn’t raised their rates very suddenly. But yes, you should still call them and raise some hell.

We’ll get to why later. In the meantime, let’s go over a few of the many reasons your bill is so insane right now.

Baby It’s Cold Outside!

Duh. It’s cold. Very cold, even here in Alabama. But what does that mean for you?

All houses have leakage points. Some houses are worse than others. Some, especially older homes, leak LOTS of that precious warm air during the wintertime. That’s a bad thing.

If possible, try to add some insulation to your house. Here’s a handy guide from Energy.gov. While you’re at it, seal off any leaky ductwork. (Yeah, that will involve venturing into the crawl space. Yeah, it’s a bit creepy down there. The good news is, you can hire someone to do it!)

Anywhere you’re losing heated air to the outside, it’s costing you a lot of money. And the colder it is outside, the problem gets exponentially worse. So get it fixed. Fortunately, these are pretty cheap and easy jobs. You’ll make your money back quickly. (When we say quickly, we mean within 2 years.)

 

Auxiliary Heat Mode and Your Utility Bill

Pop quiz time. Do you know how your heating system works? Do you know what a heat pump is? Is it running on auxiliary mode?

If you said ‘no’ to any of those questions, we have good news and bad news. The good news is that you don’t have to know exactly how your system works. If you’re curious, there are loads of YouTube videos that can give you a crash course. The bad news is that, if your heat pump is running on auxiliary mode (or aux heat), that’s gonna cost you some serious dough.

When the temperature outside reaches a certain point (around the freezing point), your thermostat will automatically turn on auxiliary mode. This turns on electric heat strips for additional heat. It’s kinda like blasting your oven on high. All through your house.

That’s understandable when it’s really, really cold outside. You gotta stay warm. Just make sure the auxiliary heat (or emergency heat) setting isn’t always on. You also want your heat pump to keep working even while the auxiliary heat is on. To do this, have a professional come out twice a year to check that your HVAC is in working order.

If you’re not having regular maintenance completed by a certified technician, chances are your equipment may not be working as designed. And here’s the problem: You may not even know! Just because it’s warm inside your house doesn’t mean the system is really working the right way. Remember that high bill?

Unfortunately, this might be a somewhat pricey fix if something is wrong. But in the long run, fixing the problem is better than overpaying every single month.

So Can I Still Give Someone a Piece of My Mind?

Yes! It’s true that your utility company didn’t suddenly change your rates. However, their rate structure is set up in a way that penalizes you when things get rough.

Wouldn’t it be nice if your utility company offered a slightly lower rate at times when it’s especially hot or cold outside? That would obviously help lots of customers who feel the pinch this time of year. Then, when the temperature is milder, they could charge a higher rate to make up for it. We think everybody would benefit in this scenario. Your utility MAY offer budget billing and if so, you should check out that option.

Another option would be for utility companies to invest in energy efficiency programs that help real people. Wouldn’t it be nice if your provider offered a program to make your home more energy efficient so you could fix all the problems we listed above? We think so, too. Then you wouldn’t need special rates and billing processes.

They know these problems are out there. But these types of programs are few and far between in Alabama. So call your utility company, city council, the board of directors, and/or the Alabama Public Service Commission. Let them know how you feel. You might just make a difference for yourself and your community. 

So Who Exactly Do I Call?

That depends on where you live in Alabama.

North Alabama (serviced by TVA)

  • Call your local utility, who buys from TVA. This is usually a municipal utility, like Huntsville Utilities, or an electric cooperative, like Joe Wheeler EMC
  • If you have a municipal utility, call your city council and mayor. They ultimately control the utility.
  • If you have an electric cooperative, call your board of directors. This information can be found on their website.

Central Alabama (serviced by Alabama Power)

  • Call Alabama Power
    • 1-800-245-2244
  • Call the Alabama Public Service Commission
    • 1-800-392-8050

South Alabama (serviced by PowerSouth)

  • Call PowerSouth
    • 334-427-3000
  • If you have a municipal utility, call your city council and mayor. They ultimately control the utility.
  • If you have an electric cooperative, call your board of directors. This information can be found on their website.

 

 

Energy Efficient Gadgets: Recommendations from Energy Alabama

Here at Energy Alabama, we’re always on the lookout for new and innovative, energy-efficient gadgets that further progress us towards a future of 100% sustainable energy. But we also love the idea of offering ideas to help you better manage the energy and resources you have now, because, you know, we’re just cool like that. So we’ve put together a list of gadgets that we believe will be of great benefit to you.

4 New Energy Efficient Gadgets For Your Home

#1: Sense Home Energy Monitor

 

The first gadget on our list is a cool little device called the Sense Home Energy Monitor. This device is great because it monitors any and every electrical appliance in your home. Every light, every T.V., and even the hair dryer in the bathroom is able to be read by Sense.

Every appliance has its own electrical signature, kind of like its own voice. Sense is able to pick up on all of those signatures and provide specific feedback about each appliance directly to your smartphone. It can tell you how long a T.V. has been on, how much power the refrigerator is consuming. It can even tell if an appliance is running on an unusual amount of energy, which could mean that that device may be faulty.

It works by using complex algorithms to recognize the different signature of every electrical appliance, such as a toaster or a washing machine. And not only that, but it monitors how much energy each device uses and provides helpful hints on how to save on energy. And who doesn’t like saving some extra money?

So, how do you install the Sense? Well, its simpler than you might think. Simply connect the device directly to the electric panel of your house, download the sense app to any smartphone, and connect the monitor to your home Wi-Fi to start “listening” to what your house has to say!

One of the drawbacks of the Sense is that it’s really best suited for buildings with only one electrical panel. Another gadget that is much like the sense, but is better fitted for more than one electrical panel, is known as Neurio. However, the interface and installation are a bit more complicated than that of the Sense, and could be a bit confusing.

#3: Solar Powered Christmas Lights

 

Next on our list are solar-powered Christmas lights. That’s right! Gone are the days of running overbearing extension cords to Christmas lights, all while trying to find an outside outlet to run them to. These solar-powered lights provide a simple solution to the struggle of powering those beautiful lights. Simply hang up the lights like you would any other, then plant the included solar panel into the ground where lots of sunlight will hit it, and that’s it!

Since they run off of their own renewable energy source, you don’t have to worry about your bill going up around the holiday season.

#4: The Kill-A-Watt Monitor

 

The last gadget on our list is the P3 P4400 Kill A Watt Electricity Usage Monitor. This device is pretty straightforward and simple with its execution and user experience. The Kill A Watt monitor can tell you the power consumption of any appliance in your home by the kilowatt-hour, the same as the electrical company. It can also give electrical expenses by the day, week, or even year. It also tests for power quality by measuring different factors such as voltage, line frequency, and the power factor. A large LCD screen shows all of the feedback in a clear and simple fashion. Simply plug the monitor into any outlet, then plug any electrical appliance into the outlet build into the monitor, and you’ll be able to choose what you want to know about the appliance. 

The U.S Department of Energy states that 20% of our electrical bills come from appliances that are left plugged in, even if those appliances are turned off. The Kill A Watt monitor can tell you which appliances in your house are steadily consuming power, which gives you the ability to save more money and power.

SELC, partners push for open dialogue around energy efficiency in Alabama

A rate increase proposed by Huntsville Utilities, a municipally-owned utility in northern Alabama, has spurred discussions around the importance of making energy efficiency programs more widely available in a state where efficiency policies have not been widespread.

“A major first step in moving the needle and opening access to energy efficiency is to start an open dialogue with utilities and make the case for financial models that remove disincentives and encourage customers to save energy,” said Daniel Tait, CEO of Energy Alabama. “We are hopeful that the Huntsville City Council members heard the message, and we look forward to future discussions with Huntsville Utilities to establish a robust, transparent process that includes all stakeholders going forward.”
