Energy Crisis - Why Do The Stores Leave Their Lights on All Night?

We have a worldwide energy crisis and electricity rates are very high in Australia. Any energy saving will help with the current situation with added benefit of reducing global warming.

So just trying to understand why do many stores leave their lights on after they are closed? Is it for security only? At least sensor based lighting should be there.

Thoughts?

    The power consumption of LED lights in a store is beyond minuscule compared to literally anything else going on with energy consumption.

    Turning your lights off won't save the planet.

      10 watts, 300 lights at light store

      That's 3000 watts which is a lot.

      Okay it's like two aircons running. Or three heaters. They would save a lot

      • +27

        which store has 300 lights running overnight? (with nobody inside).

        Most stores have a few on for security. Also, they might be restocking, or paperwork out the back etc.

          Most stores just have the bare minimum of lighting running after hours, even for just night fillers.

        "A lot" compared to nothing, sure, but that's not even a drop in the ocean of energy consumption elsewhere.

        I used to work at a tech company where no-one came in on weekends but the air con ran both days and they didn't care.

          • +5

            @skillet: My work has the server equipment in a not purposed designed closet. So we can't close the door and we can't turn the air conditioning off as it's needed to keep the servers cool. Top it all off with the inability to only turn on sections. So the entire floor plate in the office is left on 24/7 even though people are only in the office 9/5.

            Now that's wasting a lot of electricity!

      Disagree, that attitude towards it, doesn't encourage any positive change though. Lots of things on their own have little impact but collectively those "small" things compound and make a bigger difference. Otherwise it creates a lets give up type mentality. It also promotes the improved actions to society and works to change the societal perspective. Similar to single use plastic bags or straws etc. (Not that I agreed on the straws).

      • +17

        Disagree with your disagree. Lots of little things don't really have an impact yet make people feel like they're doing something good, and so they won't pursue actual solutions.

        Like if you religiously switch off lights in rooms that aren't occupied, or turn off your standby items overnight, but you disregard the installation of solar or heat pump hot water heaters.

        Or like during covid how everyone was obsessed with hand sanitiser, and stickers on the ground telling you where to stand, and you could only drink sitting down, yet shops and restaurants had all the windows closed and air-con running, circulating contaminated air.

        • +9

          make people feel like they're doing something good

          or turn off your standby items overnight

          Using Powerpal to understand my usage for my wfh setup, and my current power bill, I calculated I can save $100/yr just turning my wfh setup off outside of 8am-7pm M-F. So now I turn them all off.

          That’s more than just feeling good.

          It actually allows me to save up for the other things that will make a bigger impact.

          Don’t shame people who are trying. It’s not all instant success, and it doesn’t have to be. Doing something is better than nothing.

            @jjjaar:

            Don’t shame people who are trying

            This forum post literally asserted that we should all be doing these miniscule and debatable "savings", and the people agreeing are doing far more "shaming" than others pointing out it barely makes a difference.

            I'm not going to give a (profanity) about a bit of plastic when we're detonating nuclear weapons underwater and littering depleted uranium shells across large swaths of the globe. Does anyone still think "getting rid" (charging for) plastic shopping bags was about the environment?

            More directly to the topic at hand - how do you even know that everyone reducing their power bill by 2% a year is even a net win, if it costs us a bunch of time and effort, or even installing new "energy saving" tech in our houses? Lets see the TCO calculations/audit, and note the lost opportunity-cost of how that effort could have been spent.

          But they're not mutually exclusive. This is presented as a false dichotomy, in that those who take effort to switch off their lights are going to neglect more substantial actions.

          In reality you'd probably find those more concerned about frivolous consumption are going to be the ones pursuing those ideas (i.e. getting solar).

            @thrillhouse: The missing step here is education.

            those who take effort to switch off their lights are going to neglect more substantial actions.

            I believe this is the case due to lack of (correct) education.

            • Earth hour teaches us to turn off our lights to save the earth.
            • I've seen people switch off empty power outlets to save power.
            • People run their oil heater instead of their AC because they think it uses less power / keeps the room warmer for longer.
            • People try to cook less to save money on their energy bill (it makes hardly any difference)

            Yet they still have 20 min warm showers.

            If people believe they are doing things to save power, despite them being potentially wrong, they won't seek out the proper education to learn how to actually save significant power.

            We should discourage the little things that are outright wrong, or do hardly anything, and instead focus on education on what the most impactful things are.

The same people then preach to others that people using straws are responsible for killing the planet.

              • @lunchbox99: There's a term for such people. The middle class. Greedy, selfish people who believe a bit of virtue signalling will atone for all of their transgressions.

              Hilarious. Clearly so dumb they don’t know that an empty outlet is an open circuit and not consuming any power at all.

            @thrillhouse: It's actually not a false dichotomy, at least not completely. Your assertion doesn't take into account we have a time and effort budget in our lives, so everyone has to make trade-offs about what to care about. Micro-optimizations in your every-day life often have a relatively high cost. There is always more you could be squeezing out, given enough time. (Basically) nobody lives even remotely like this though, the vast majority of warriors for ecology/bargains/recycling/energy/coral just have their pet optimizations (or hates) they love to promote. For some it's just "plastics" (even though they drive a novated lease car which is 90% plastic and get a new one every 4 years). For others it's not eating meat (even though they go on holidays via air, etc). etc etc. I actually have known people that attempted to "take it all the way" and they literally lived in the forest. Ironically that's still not sustainable, they still relied on (some) mass produced goods and had some energy budget, and they were excluding themselves from work on larger scale root causes, such as materials science that could improve manufacturing.

          Have you done any research to find out how much energy is saved when 8 billion people and companies turn off lights, or are you just assuming it's negligible as it would conveniently absolve you of responsibility?

          • +1

            @callum9999: Both, I assumed, and now I just looked up the research and confirmed it's negligible. Measured drop of 4% in one hour of a year (1 in 8700). That's an annual change of 0.00046%.

            That wasn't even my point anyway, it was that people thinking that they've made a difference is enough to stop them from seeking out any further, and potentially more effective, ways of having an impact.

        • Look, it is true that if you are more careful and turn off the lights when you're not using them you might only save 200kg of coal from being burnt every year. Where as, if you install solar panels, you can save a massive 5000kg of coal from being burnt every year.

          However, why not do both, waste not is an important concept and everyone's little bit helps out a lot. I try to automate as much as possible around the house that that lights & switches switch off automatically when not required. That way you can do both and not require too much effort on your part.

      • +2

        . Lots of things on their own have little impact but collectively those "small" things compound and make a bigger difference

        Nah. If you add up a million 0.1 'things' that is still nothing compared to one hundred million 'other things'. The effort/impact of the individual vs an industry is laughably small.

        Otherwise it creates a lets give up type mentality

        It's not a binary choice, either focus on the little things or give up. The effort should be in holding industry and businesses to account with their actions.

        The biggest con of climate change is big business marketing it so that the responsibility is on the individual and their actions, not the business itself and the impact on climate change.

        Hell, even look at celebrities or Prince Harry. They'll take private jets to conferences to talk about climate change, making more damaging changes in one trip than you will in your entire life of 'turning off the lights' and sweating with the fan on instead of air con.

        • Hell, even look at celebrities or Prince Harry. They'll take private jets to conferences to talk about climate change, making more damaging changes in one trip than you will in your entire life of 'turning off the lights' and sweating with the fan on instead of air con.

          This is the part which shits me. A 7 hour flight between New York and London on a private jet puts the same amount of CO2 into the air as me driving our car for 14 years at 10000km per year.

          We can turn off all our lights, sweat without air con, sort our rubbish, and industry will still blow us all out of the water with their energy usage and waste.

          • @whitey1212: As above, business is polluting on your behalf - not for fun. You choose to pay them to do so.

            Rich people invariably have a much higher impact than the rest of us, agreed. If you want to spite them for it and kill the planet in the process then go ahead, but don't try and pretend you have no choice. They are a tiny percentage of the population so their outsized impact is still a tiny percentage of the problem and if the general public did their bit then it would still significantly help.

            That being said, as this thread demonstrates, even people who profess to want to help the planet invariably can't be bothered to do so, so my personal belief is that we're already beyond the tipping point and the climate will now irreversibly change. I still do my bit because it makes me feel better to know I'm not particularly contributing to it, but it seems futile to try and convince others now. (My one exception being to assign responsibility - if you don't care then fine, if you say you care but "can't" do anything to reduce your impact, or refuse to do anything because "someone else does less" I'll definitely object!)

        • It's not remotely a con. "Big business" isn't polluting for fun, they're polluting because you and everyone else specifically asks them to by buying their products. We are the ones paying them to do this, and you can absolutely stop/reduce those payments if you actually want to.

          I think this is an incredibly lazy way of thinking that's specifically designed to justify why people can't be bothered to do your part.

      • Nah mate easier to blame the boomers. It's all their fault.

      While I do agree with you that turning lights on or off is mostly a red herring when it comes to concerns over energy 'waste', however…

      The power consumption of LED lights in a store

      There are still plenty of high-intensity discharge lamps, older halogen or even incandescent lighting fixtures to be found in commercial/retail premises, especially in older buildings.

      Most studies I could find put the uptake of LED lighting in the commercial sector around 50% or so (but there don't seem to be more recent figures since 2018 and most of these are American studies, so factor in a larger percentage of non-LED lighting in countries like Australia where we're generally speaking years behind current trends).

      Look at a larger shopping centre at night or higher-end department stores/boutiques in more upmarket shopping districts. They'll have dozens of halogen flood lights (probably in the several hundred watt range) covering outside parking/heavily-trafficked areas and the interior lighting can often feature halogen reflector globes as well, which while more efficient than older incandescent globes still use a lot more energy that LEDs or fluorescents.

      Many older display cabinets/shelves or store front displays will also have bright halogen or incandescent globes as well.

      LEDs made up 50% of lighting sales in 2019 and while I can't find any more recent statistics it stands to reason that there's still a lot of non-LED lighting in use in the commercial/retail industry.

      • Fair point, didn't know about the scale of non-LED still being used, but wouldn't that all pale in comparison to even just the aircon in a shopping centre?

        Feels like 'lighting' is the least of our worries

      • Halogen lighting for outdoor flood lighting isn't really that common. Most of the older non-LED commercial outdoor flood lighting is usually discharge lighting (typically mercury vapour for white lights and sodium vapour for orange lights). Sodium vapour lights are pretty energy efficient compared to halogens and have quite a long bulb life.

    • Switching them off would save the lights though- they'll have to pay to replace them in a few years if they don't turn them off.

      Switching them off would make that quite literally a 'never have to do thing'.

    • Lighting is up to 10% of the power usage of a commercial premises, so not as "miniscule" as all that:

      Um…. Yeah… Nah.

      Just keep believing that most retail theft is conducted by stealthy nocturnal Hamburglars.

      It's just a trope (and lazy) to say that putting up lights will fix (or even mitigate) theft issues. Like…. how has worked out for the last, what? hundred years?

      It's easy to sell exterior lights (and cameras for that matter), as people don't generally critically examine where and how most attritional loss occurs. "Oh, it's common sense" is not necessarily an ideal rationale. "Oh, maybe I should look at my supply chain, logisitics, warehouse storage, contractors, staff, and executives" is more pertinant. Nah… Just buy lights and cameras.

        Lighting is 100% a deterrent for break ins. Have seen it happen multiple times where the poorly lit stores get their windows smashed etc over ones with lights all over the place.

          I don't think we are talking about this at all.

          We are discussing the issue of internal lights and other appliances (such as air con) being left on 24/7 when there is no occupancy.

          • @DoctorCalculon: My parents used to run a large furniture store. They left the lights on in the front section (visible part) as a deterent to thieves as thieves don't like being visible. Secondly they regularly left air con running in summer despite hating the cost as the heat even at night where they were actually affected the goods, especially wooden furniture which would cause glues or joints to expand or contract, We also used to have to put out glasses/bowls of water when they wanted to leave the air con off to help provide some humidity. So yeah it is not all laziness, many goods are affected by temperature changes too.

    Fossil fuel electricity generation (which is what we mostly use) are always operating because they ramp up and down outputs very slowly. From an energy cost perspective, the shops are actually doing the right thing by using electricity when the majority of people arent. They are using "free" energy which would otherwise not be used.

      To do something productive - yes. To do something unproductive - no. Therein lies the dilemma - what real value does illuminating an empty space bring? Maybe different answers for different places at different times; surely not required for all places all the time.

    • Depends which state, but that's less and less true as time goes by, e.g. SA just ran the whole summer on 80% renewables.

      Also that power could probably be used somewhere else via interconnectors, you don't have to 'burn' it pointlessly.
