Electronics require lots of metals that are sourced through mining. Mining is an essential but dirty business that often leaves pools of toxic heavy metal water behind. These pools are damned up, but inevitably leak out into the surrounding environment.
It’s important that everyone Reduce, Reuse, Recycle properly in order to reduce our impact to the environment.
- Robotbeat 6y agoYou know what requires a lot more metals? Cars and houses and apartments and railroads and highways. When we’re trying to reduce our impact on the environment, we’ve got to not waste time on the small fry while ignoring the elephants. Problems should be attacked proportional to their impact. Don’t think that using metal straws but driving a new gasoline powered SUV is making an improvement.
- coldpie 6y agoWe are now at the point where everything matters. Industry is responsible for about 21% of GHG emissions globally (more than transportation!)[1]. Reducing that by using simpler technologies is a good thing to look into. Do you really need to replace your perfectly functional doorbell with a big pile of electronics? Probably not. Would not driving to work every day make a bigger contribution? Yes. Would not doing either be best? Yes.

- Robotbeat 6y agoUsing an incandescent light bulb is not “better” than an LED bulb, even though the latter is a “pile of electronics” while an incandescent bulb is just a little tungsten wire. So I really don’t think this is a good rule to follow. Simpler technologies are often far less efficient and often have a far larger ecological impact. LED bulbs are comically more efficient than incandescent bulbs (by a factor of 5-10), which in turn are comically more efficient (by 10-50 times) than like a candle or oil lamp. “Simple” is actually a terrible heuristic for “low ecological impact.”
- coldpie 6y agoAre you really making the claim that a simple doorbell switch has higher environmental impact than a Ring doorbell?
- Robotbeat 6y agoIt actually might. If the Ring doorbell allows you to avoid opening your door just once or twice a week, the energy savings could exceed the environmental footprint. A Ring doorbell has a 22Wh battery that lasts about a month or two per charge. Having the door open for 10 seconds on a cold winter day can easily waste that much energy. About 10kW of heat loss for 10 seconds is 100kJ, higher than that 22Wh. Likewise, the embodied energy of that 22Wh battery is about 22MJ, and might dominate the embodied energy of the Ring camera. So if it saves you from opening the door 200-300 times in its lifetime, that might be enough to pay for its own embodied emissions. Plus not having to drive home to pick up a package, etc, etc. Plus think of other smart devices like smart thermostats that might be part of the whole Ring system. Or perhaps if the Ring device prevents destruction of part of your home from theft. I don’t even own a Ring doorbell, but I can see how it could actually help. Also, traditional doorbells aren’t that efficient. Especially if they have a little light. Ring could also replace a window to see who is there, which is a big source of heat leakage.
- harpastum 6y agoThe argument is that the "simpleness" of the doorbell isn't a good heuristic for the amount of impact. According to wikipedia [1], the transformer on a standard doorbell can use 2-3 watts of power at all times. That's 1400-2100 watt hours per month — about one hundred times as much as a ring doorbell uses (Less than 20 Wh per month). The cost and impact of the Ring includes more manufacturing, and I wouldn't be surprised if the Ring ended up having a larger environmental cost, but it's not as clear cut as your incredulity makes it seem.

That's 1400-2100 watt hours per month — about one hundred times as much as a ring doorbell uses (Less than 20 Wh per month). Interesting thing to know because here in Brazil we don't route PELV (Protected Extra-low Voltage) to the doorbell. The external switch just carries the full voltage from the mains (127 Vac or 220 Vac, according to the state). Maybe it's not the safest design after all. However this constant power usage can be safely removed by using a non-rechargeable 12V battery that would power a relay that will trigger the mains-powered bell when the (purely mechanical) external switch is pressed. This removes the constant power usage and such battery should last for years with a typical usage scenario (less than one second per push or so).
- eldaisfish 6y ago>We are now at the point where everything matters You are missing the point and mischaracterising the problem. Resources are finite. Human attention spans are limited. Emissions from ships in international waters are an absolutely huge problem and addressing that will make a huge impact on future climate. Funny how no one mentions that but we are all focused on paper straws and smart doorbells.
- acka 6y agoIt is all related, so everything taken together does indeed matter. When we as consumers insist more on buying locally produced, durable, interchangeable, replaceable, repairable (!) components to build things we're actually likely to use for a long time, we can stem the flow of cargo ships and ditto planes shipping "stupid disposable junk" halfway across the world, thereby limiting all the pollution and waste of (fossil fueled) energy that goes with it. While we're at it, we should demand to put an end to the senseless hoarding of patents and IP, in particular those that hamper interoperability between components, and for information on interfaces to be made public, so no more proprietary connectors, protocols, APIs, no more artificial restrictions on consumables such as printer ink, etcetera.
- stonesweep 6y ago> You know what requires a lot more metals? I believe the argument is about the refining process and the chemical waste it creates, which is substantially higher when trying to extract 99.99% pure copper, zinc, gold, silver and other industrial elements which are converted into electronics. I'm a hobbyist fan of silver and know just the basics - refining for 99.99% pure silver looks like making crack to my eyes. :) Breaking Bad level chemicals. I'm to understand the act of creating and "washing" circuit boards also uses a large amount of caustic chemicals, as does the attempted recycling/recovery (to basically eat away the coatings to expose the reclaimable metals). Refining for purity has a high environmental cost to get it from ore -> 99.99% and to reuse/recycle it, I speculate much higher than iron ore (train tracks, etc.) require/use.
- Robotbeat 6y agoInteresting claim, but to justify a few milligrams of metals is worse than literally tons of metal and cement is going to require a quantitative argument. 99.99%, even if you’re right, only gets us to 10kg equivalent if you start with 1 gram. (And keep in mind that these processes to make bulk materials themselves use alloying agents and specialty materials in cutting heads, etc, to fabricate them.)
- stonesweep 6y agoIt requires tonnes of ore processed to produce ounces of gold (I read roughly 13 tonnes on average, but it's highly dependent on the quality of the deposit and refinement difficulty), there are metrics and studies: https://www.businessinsider.com/tons-of-rock-for-an-ounce-of-gold-2013-4 https://www.businessinsider.com/tons-of-rock-for-an-ounce-of... Edit as I'm curious myself, this study shows it's about 150 tonnes of ore input for one ton of copper output (with other minerals reclaimed during the process): https://www.princeton.edu/~ota/disk2/1988/8808/880811.PDF https://www.princeton.edu/~ota/disk2/1988/8808/880811.PDF
- Robotbeat 6y agoKeep in mind your conventional car’s catalytic converter contains grams of platinum group metals, worth about $1000 or so now ($3000 for older, larger catalytic converters). Due in large part to the spike in rhodium prices.
- midasuni 6y agoLocal odeon stopped using plastic straws in their drinks. Paper ones were awful. Bought some metal straws also awful. Ended up taking 2x500ml bottles instead - far more plastic than was used before. Yeay?
- sixstringtheory 6y agoStop using straws... completely unnecessary. Use a reusable water bottle. One can be had for the price of those 2x500ml bottles.
- midasuni 6y agoI don’t want water. Charge me for the plastic for the 6 straws a year I use, which is far far less than the plastic others “waste”. Put a price in the pollution and let the market sort it out
