Isn't 1.2g per page view huge amount? I wonder if we can have api for this.
- magnio 6y agoAccording to Website Carbon Calculator, each page view produces 2.22g of CO₂. I think it would be lower if you use an ad blocker. https://www.websitecarbon.com/website/bbc-com-future-article-20200803-the-solar-canals-revolutionising-indias-renewable-energy/ https://www.websitecarbon.com/website/bbc-com-future-article...
- walrus01 6y agoI really have no idea how they're calculating that other than a lot of hand-wavy math. It will vary greatly depending where you are. If I'm in Vancouver and I access CDN or hosting resources from a massive datacenter located in WA or OR, it's highly likely that 98% of the energy for my home, and all of the telecom/ISP sites in between, and the datacenter itself are all hydroelectric powered.
- adrianN 6y agoThat power could be used elsewhere in your power grid. It probably makes sense to look at CO2/kWh averaged over the whole grid.
- soperj 6y agoDespite our government repeating it over and over, it turns out that Hydro is actually worse than all fossil fuels in terms of GHGs (over double coal) depending on what you flood. If it's forest, it's the worst. For the W.A.C Bennett dam in BC, 350,000 acres of former forest land was flooded.
- Alupis 6y agoOK, but it's not being re-flooded constantly, it's already done and can't reasonably be undone. So, long-term, it's a fantastic renewable resource with practically zero emissions.
- soperj 6y agoSee sibling comment. Practically zero emissions is false. It results in over double the GHG emissions per year than a coal fired plant producing the same amount of energy.
- Alupis 6y agoThat is crazily misleading. For the initial construction, yes. Ongoing? No. At a point in time, the amortized emissions become zero.
- soperj 6y agoIt's not misleading. The vegetation that is flooded decomposes anaerobically and releases methane. So there's an ongoing release over the years that it decomposes. They've measured these emissions at different dams over time, and the worst (where forest is flooded) results in nearly 2.5 times the GHG emissions as the worst coal plants. For instance the Balbina hydroelectric reservoir in Brazil was responsible for 39000 tons of methane each year (https://www.researchgate.net/publication/252089237_CO2_emissions_from_a_tropical_hydroeletric_reservoir_Balbina_Brazil https://www.researchgate.net/publication/252089237_CO2_emiss...) That was a 2011 paper on a dam that was finished in 1989.
- Alupis 6y agoThat is still misleading, grossly. More happens in the water than just releases of methane - there's plant and animal life producing oxygen and consuming decomposing materials. Plus 1989 is a brand new dam. The Hoover Dam was completed in 1936[1], and is expected to have a service life of at least 10,000 Years.[2] 10,000 years at a minimum. It will have paid dividends in renewable energies so many times over by then, that it's not even worth discussing. Do you think the solar panels installed on your roof will last 10,000 years? Will they even last 10 years without needing replacement or repairs?

- renewiltord 6y agoWell, you exceeded that in 5 minutes yourself by just existing.
- Baeocystin 6y agoSome envelope math. From https://www.eia.gov/tools/faqs/faq.php?id=74&t=11 https://www.eia.gov/tools/faqs/faq.php?id=74&t=11 , I get .99 pounds of CO2 per kWh. That converts to 449 grams. Splitting the difference between 1.2g and 3.6g, we get 2.4g. 2.4/449= 0.00534 or ~0.53% of 1 kWh consumed, or 5.3 watt-hours. Which does strike me as rather high.
- adrianN 6y agoThe page took 20s to load for me. That's about 1kW to get the ~5Wh. That seems reasonable. Just my internet equipment consumes about 50W, and there are many servers involved in loading a BBC page.
- throwaway_pdp09 6y agoLoaded in well under 2 secs for me (no JS, all ads blocked, not that there will be on the bbc)
- manquer 6y agothey might have third party trackers though
- Baeocystin 6y agoMakes me wonder just how much power/carbon waste goes in to ads vs content on the modern web.
- CyberDildonics 6y agoA pi-hole dns filter will typically block 10%-30% of all domain queries (for a fast and loose estimate).
- throwaway_pdp09 6y agoTell you what, why don't you give it a try? It should take 30 secs to disable JS on firefox, then see how it feels, re-enable it afterwards. See what a snappy web can feel like (when it doesn't break, which is ~30% of the time). I keep saying it, strange that nobody has ever said that they tried it. There seems to be some weird mental block around trying something new, even if easy to do and with possible benefits. Why is this?
