 It said itself was a country that would make the sixth largest country to use electricity. It's quite high. It's known as high as the United States, which is figure number one. Maybe Russia is number two, I haven't checked through this. But yeah, it's quite high. At my description, I had a lower number of the metric tons. I found out it was number two thousand thirty. I looked for the twenty-twenty numbers and those are about seventeen hundred metric tons of carbon footprint. That's currently what you can use. If you can use, that's how much carbon footprint is, and that's quite a lot. So how come those numbers aren't big? Well, in 2008 there was a paper that suggested if you want to create and transmit one gigabyte of data, it would say about thirty kilowatt hours to do so. And this is an average for the US power plants, but yeah, some countries have higher, some countries have lower, but yeah, I think I'm going to go down to the US at this moment. So one of the problems with carbon dioxide equivalent is produced per kilowatt hour. And then carbon dioxide equivalent is not only carbon dioxide, it's consuming more gases that hurt the whole body. So that's very stable in the air. So this would result in a fifty point six pound of carbon dioxide equivalent to twenty-seven point gigabyte of data. And an average per page is a site of one point four megabytes. So one billion visitors, and that's very positive if you have that large site, but yeah, if this is your page, they would create all 10 tons of carbon dioxide equivalent. And that's quite a lot. So if that's just for one page, consider what you're diving in there. So what can we do, or can you do, to lower your carbon footprint? Well, use less streaming. Honestly, if you want less Netflix and anything, you can use streaming. Because you wouldn't be able to travel properly, because all streaming videos make up about seven percent of the carbon data currently. So that's quite a lot. But the points I'm going to talk about is how you can improve your oxygen. I think you can improve your performance, which you can do during design in the wind stage, and certain optimization in your vulnerability. Those are the four topics I will talk about, and how you can improve your carbon dioxide footprint. So let's start hosting. The obvious one, use three hosting parties. So yeah, if they use host parties that transfer electricity on renewable energy, that lower the carbon footprint, of course, pretty low. Yeah, because service around 24-7, they need electricity all the time. So yeah, if they use minimum power or solar power, that will be a lot more beneficial than coal or any other, or a few power sources. There are also renewable energy credits that some companies get, or say they use, but that's not a guarantee that they are using electricity or green power themselves. It's just that somebody sold those credits to an energy company, and the energy company says, okay, I didn't have this credit, so I agree. But that doesn't prove that they are using electricity with their own power as well. So that's not a guarantee. You can use a virtual private server or share hosting. Just think of it as carpooling. You share the emission if you would drive together. Well, here, if you share an insert together, you share electricity that's being used. So you're going footprinting if everybody has their own server. You can use a coal delivery network. Yeah, the distance, the real physical distance between your visitor and your website could be quite large. So if you have a CDN, those distances can be shorter, and in the shorter yard, the faster you work and the less energy you use. The real turn point is about having 5,000 visitors per day. If it's low in there, it's not really that beneficial. You don't see any big changes. If it's more than that, you will definitely see changes. And if you have a website that's low only, or at least mostly used low only, then this doesn't matter as well for you. And this is used for this. I want to change the use cache. But yeah, just use proper cache. Like for this or memcache or relish. If you use the cache from the memory of the server. That means that the hard drive is inside of those. Don't have to burn. It should be specifically used. And it also includes your speed of the website. The faster the site you get to the visitor, the less energy you can use. So that's about hosting. Are there any questions about hosting? Performance. And luckily, the further part of the performance is also in the cache. Like I said, the faster the site is on the device, the less energy it will take to get there. So yeah, I'm not going to repeat myself any further. Aggregator and JavaScript in CSS. For every time a page needs a JavaScript file or a CSS file, it will do a new request. And every request will ask for more energy. So if you lower the number of requests, that will be beneficial. And also minimize your files and make them as small as possible. So you get the files very fast. And also minimize your own page itself. Make it as small as possible. Proper use of images. If you have a small image from a mobile phone and you put an image there that's four or five times the size that it needs to be, that's just lowering and putting it down on your phone that it's not really necessary. So that's a waste of energy. So make sure that your images are the correct size. Maybe use a picture there to make sure that you only use images depending on the device that's being used. So what can you do from a designer user experience standpoint? Well, I'm not a UX designer myself, so it's not my area of expertise. I know there's a lot of things to take into consideration. But again, the proper use of images. Make sure you use the smaller images if necessary. Maybe even use sprites if you use a lot of items. Make sure you design mobile first. Because mobile design is usually the smallest design necessary. So that will be the fastest. And make it grow and determine on the device that's needed. Use of colors and fonts. It's true that darker colors need less energy, especially light. So yeah, everybody wants to do the right side, of course. It's something you need to consider when you are designing a website that's fit for the brand that you are. And for fonts, yeah, basic system fonts are the fastest noted because they hold many new systems. So R&L and Latin are the most commonly used, even in the artificial sciences as possible. But yeah, not everybody wants to have their own fonts. So there are two options to use web fonts or embed your fonts. But this will cause extra requests or make your page size a little bit bigger. Which of course makes sure that you have a goal more. So those are all things that you need to consider in your script. And a big part of that also is the ease of navigation. That's about how easy it's everything to find. You can make a big miss in your whole website and make sure that we stay long time. But that will require a lot of basic rest. That will make sure that they will have a lot of issues. Maybe not finding anything, it may even be, but that's hopefully not the case. But if they find anything easy, they don't do a lot of requests, which saves again a lot of energy. So yeah, also make sure that you have, if your page is quite large, you can probably search functions so that they can find things even faster. So now that we're talking about searching in general, the search engine optimization is to make sure that if Google locates your site, the site is really what they need. So make sure you have proper use of your keywords. Make sure that the keywords you use are in the title. They are in the URL. They are properly used within the content. So if somebody fights your page for searching for something, the page is useful. So it's not doing a request to your site for nothing. It's nice that you have got a visitor, but if it doesn't help them, then they wasted energy to go there. I did a presentation about search engine optimization yesterday. So furthermore information about the keywords and then we can kind of review that one. That's already the line of thought. And there's also a use of redirects. And we all know the existence of search engines. And yeah, it is nice to tell them, I cannot find anything, but it means that the person went there and did a request to talk to them or wasted energy to get there. So make sure that if something is removed, you have a proper redirect if necessary. For example, also, if you have 403 pages or somebody doesn't have access, don't link them to the login form to say, oh, you can log in here and then you can see the shuttle login form directly says another request. So I'm going to read it. Yeah, that's about it for those things. If you want to check that your site is green, you can go to www.engelcrayer.com and put the video out and it will tell you where you can score for your website or how much you score or how much you score to prove that you don't need to check if your policy provider is green. So that's nice. But of course, energy is not electricity and of course, you're welcome to read it. Make sure you bring it to the supplier and if you're going to reduce stimulus items, make sure you use less plastic, recycle as possible, don't bring it if you don't need to, that sort of stuff. And yeah, I don't want to be pushed and say, you have to do this, nobody's perfect. I know that I know and I don't want to stick with you with the environmental stuff. So, yeah, we don't need to be perfect but at least if we all do something, we will get a better plan. In a way, through my site, it's a way faster than this. So, are there any questions? Any questions from the audience? Yes? If we took a site and we did all of those things, if it had been not green to start with and then we did all of those things, how much difference can it make? Okay, I have a question for you, grab a little bit. Let me see if I can move the mic a little bit. It does. My question was, how much difference can we make in terms of CO2 equivalent? If we use all of those best practices? Yeah, it depends on how big and popular your site is. If your site has just visited a couple of times a month, the impact will be less. The biggest impact will be your hosting provider, if that's green, and that will be the biggest impact. If your site is really big, it can be very, possibly that everything you do that is green, it can be saved up to, well, like I said, the 500-page site is 1.4 megabytes, and that's there. So, if you can go with that, then you can see how much you will save. If you go back to 1 megabyte, you're still 1 million users, so you drop about 7%, then you drop 30%, so you will be 7% of CO2 equivalent that you will save. So, making everything fast and small is just the answer. Okay, thank you. Any other questions? No? Okay, thank you very much.
