Ok: not a car pic for an example, but it makes my point.

EV’s must not fall into the trap of calling themselves zero emissions as it depends on where the electricity comes from. If you know the power cane from a wind farm or solar farm: all good. Otherwise marginal grid power is gas or coal so it’s not a zero emission car.

And let’s not confuse tailpipe emissions like NOx and SOx and particulate matter with carbon dioxide equivalent or green house gas emissions.

EV’s offer zero tailpipe emissions. Let’s be clear about the difference and make sure we understand that some petrol cars running on low carbon sustainable fuels can offer lower carbon emissions than an EV!!

Does anyone know of a 3rd party tool that can be used to measure regenerative braking in an EV?

ELECTRIC CARS - REALLY? I’ve been thinking about this for a while and I just can’t see how electric cars will fix our problems. So despite the UK government saying they will ban the sale of petrol and diesel cars from 2035 and ahead of a full ban from 2050 what is the reality? ENERGY Let’s start by looking at the UK energy usage, quick look on google shows the following: - 2014 we used about 2,249 TWh (193.4 million tonnes of oil) - That equates to 34.82 MWh per capita, up from 21.54 MWh just 4 years earlier - Around 40% of our electrical energy is from fossil fuels, 30% from renewable energy sources, 20% from nuclear and 10% from imports (Drax Electric Insights) - RAC reports that around 45bn litres of petrol and diesel is used every month - With average mileage per year of 7,600 miles per car and 32.5 million cars that is 380 billion km per year - An electric car will use around 15 kWh to cover 100 km So to move away from petrol and diesel cars we will need more electric to charge these electric vehicles. Let’s review those figures, we already import 10% of our fuel and using the above distance we will need in the region of 57,000,000 MWh more electric per month than we do now to run those cars. That is 685,000,00 MWh per year! With a population of 66 million people this would mean an electricity increase consumption of 10.4 MWh per capita - with a current use of 34.82 MWh this means that to get rid of petrol and diesel cars our electric consumption will increase by 30%, even with technology advancements and that being halved it is still a massive increase when we already import 10% of our energy. So I’m somewhat skeptical about where this will come from because if every other country has the same issue, then they’ll be reducing not increasing their exports to fulfill their own needs and targets. Couple this with a desire to move away from fossil fuels which deliver 40% of our energy and you quickly start to see the problem. THE BATTERY Next let’s look at the life of an electric car battery. According to Inside EVs the lifespan is around 100,000 miles or 8 years, which means that between now and 2035 every car will need batteries replacing, twice. It is estimated by 2030 that worldwide 2 million metric tonnes of lithium ion batteries will need recycling every year, the UK would account for at least 3% of that with 60,000 tonnes. Whilst they can be recycled we currently only manage to recycle around 5% in Europe with the rest ending up in landfill. In addition, whilst 80% of the precious material can be recovered during recycling, recycling itself will of course require more energy consumption. The process is very energy intensive requiring smelting and high temperatures with only a handful of plants worldwide. Even if we get our recycling rates to 50% that’s still a lot more energy required or if we just put them to landfill we’ll soon start to run it if the precious metals and resources just like oil and other fossil fuels. POLLUTION LOCATION Air quality across the world is becoming a major issue, with some cities choked by smog and face masks needed. So the advent of the electric car sounds attractive, but let’s look a little deeper. Currently petrol or diesel is extracted, sent in pipes, refined and then sent to storage where it sits until it’s sent a petrol station, usually by tanker and you put it in your car. The majority of the pollution is at the point of use, so when you’re sat in a city traffic jam all those engines are kicking out building that smog. Compared to an electric car, where the energy comes from a power point and the pollution is somewhere else. But isn’t this just moving the problem? It smacks of “out of sight out of mind” and “not on my doorstep”. Even if the UK were to import enough energy, even if another country can recycle the batteries aren’t we just moving the pollution to that country to avoid an issue ourselves? And if we do it all on-shore we’ll need well over 25% extra energy at a time when our consumption from 2010 to 2014 already went up by 60%. We currently have 5 coal power stations and 15 nuclear reactors, however we plan to retire almost all of these by 2030, meaning any new ones will simply replace the old ones. So where is all this extra energy going to come from? CLIMATE It was reported this week that the sun is going into a low energy period over the coming decades, this is likely to result in a 1C drop in global temperatures (possibly counteracted by climate change). In turn this will mean people will use more energy to stay warm, further pushing up energy usage. UTILITIES Utilities splits into three parts: - The location and facilities to charge these cars; Unlike a petrol car where you can drive in and fill up and drive off, electric cars need to sit for a long period to charge. Therefore you either need a charging point per vehicle or you have to be able to charge super fast and go. All the roads will need digging up to install them. Either way the disruption will be immense to make this happen and where does the money come from to achieve this? You’re talking about digging up every single residential road in the country, every car park, every town and city parking area. - The resources to make them; Who will make all the charging points over this period, as far as I can see no one is considering this yet but we’ll need millions. If you have 33 million vehicles in the UK you need at least for times as many: home, work, general parking at shops, parking at other shops in the area etc. More importantly because we can probably mass produce quickly (at a lower quality) where are the resources going to come from? Think of the plastic for all the charging points, cables which are also coated in plastic, the power dig up the roads and to do the installs and manufacturing. And then of course the batteries and the mining of the resources, this becomes a vicious circle quite quickly in that you’ll need to replace batteries every say 5-10 years but you’ll be mining with battery powered vehicles and across the world we’ll quickly run out of batteries as resources run dry or we can’t maker them fast enough. Stock piling will work to start with, but this will quickly deplete. - The actual power; What happens when there’s a power cut? Everything grinds to a halt. Let me paint a picture, the year is 2050 and all petrol and diesel vehicles have been banned, the country is hit by a storm taking out two key power plants, we no longer import energy. Day one is not much bother but day two the power starts to run down, it’s two weeks before the power stations will be back online. Day three, fall out from the storm has caused more chaos but the emergency services can’t get to help people because their vehicles have no charge, residents can’t escape endangered areas for the same reason. Over the next few days things go from bad to worse, people try to drive on what juice they have but quickly the roads become blocked by people stuck with no power. No one can get to them because they are out of power themselves. Did I mention it’s winter and the storm was heavy snow, people are now stuck in their cars with no heating and either pass away in their vehicles or trying to get to safety, the elderly and frail can’t get help they need, hospitals can’t get resources to save people, shops can’t get their food supplies. Protests erupt and shops are looted for what little they do have, police and army are called in but they too are out of power. The problems spread like wildfire through the country as people become more and more desperate. Then reality hits... the power plant after a week will never come back online because we now can’t get the parts to the north of Scotland where they need to be, planes need to stop over due to the range as they too are electric. But the same thing is happening across the world, all of Europe engulfed in a snow storm bought on by climate change, the US with earth quakes on the west coast and disasters whilst the east coast is blanketed with snow too. This all means the west can no longer support and get aid to other parts of the world. The knock on effect of going electric is utterly immense, I may have exaggerated a little but it’s not a huge leap as you can see to get to this scenario. CONCLUSION We already use more energy than we generate in the UK, our demand is rising and not slowing, it is energy intensive to recycle the batteries and we seemingly have no plan for where the extra capacity will come from. In addition, the pollution problem isn’t ultimately fixed, it is just moved from the point of use to the source of power plant and recycling facility. So I’m still not clear how petrol and diesel cars will cease to be sold in just 15 years time, unless we have massive advancements in technology or massive changes in our energy usage. https://scottelliott10.wordpress.com/2020/02/06/electric-cars-really/ As the saying goes “Be careful what you wish for, you might just get it”.
