How the electric car is not always green
Electric cars Aren green t is a little overall bait against-intuitive, but it is bad in mathematics is how the argument, again and again.
Electric cars have higher manufacturing emissions than normal cars electric cars also use electricity that has its own footprint and set up these two factors are a dirty little secret that deny any climate benefit of electric cars.
One of the most annoying things on emissions of articles on the electric car is the way it's always very black and white in a corner, you have the zero emission brigade and in the other the worst crew the combustion engine.
The reality is that even after you account for the largest footprint of manufacturing an electric car, it's all about the fuel mix of the power you use, the juice if you like.
Using electrical power cut emissions cars do nothing coal-fired, electricity from natural gas, they're like a hybrid top and using a low power carbon they cause less than half of total emissions best vehicle combustion, manufacturing included.
In our recent study Shades of Green Electric cars carbon emissions around the globe grid we calculated the electric car power emissions in twenty countries, but we actually had data for some other countries, we did not want t Include.
Then s break the data and put this thing to rest.
The map below compares the carbon footprint of electric driving using electricity of the average network in 40 countries The actual carbon intensity of the electricity you use may differ from the national average for a number of reasons but it is an excellent starting point.
The results are presented in terms of grams of equivalent carbon dioxide per kilometer vehicle g CO2e km Each estimate includes emissions from the manufacture of the vehicle, the combustion power plant, upstream fuel production and losses of the grid .
The specifications are based on an all-electric vehicle, similar to a Nissan Leaf, using the 2009 average fuel mixture in each country, for each country vehicle manufacturing emissions are assumed to be 70g CO2e km, on the basis of a number of detailed studies in the report.
Of the 40 countries covered by this card issue vary 70g CO2e km hydro love Paraguay, to a 370g CO2e km heavy coal using India The US average is 202g CO2e km, China is 258g and 115g in Canada.
In Paraguay, virtually all emissions come from vehicle manufacturing, as the power is incredibly low carbon while in India, the break is 70g for making vehicles, power plants 200g, 30g for production fuel and a huge 70g for network losses.
The colors of the legend divide countries into five groups according to carbon intensity As you can see, even after production of the vehicle is included the carbon intensity of driving an electric car varies from 5 times based on the juice.
For some reference, the US average gasoline vehicle is up to about 300 g CO2e km, while a new hybrid could manage km 180g CO2e after you include vehicle manufacturing, fuel combustion and fuel production .
Because grams per kilometer is such a funny well it is nice to convert the results to something more familiar working back from the data we can estimate what type of conventional vehicle occur if any similar programs.
For lack of a better phrase Call it the emissions equivalent gasoline car.
In the heavy coal India, China, electric cars in Australia and South Africa using the network power are like a typical gasoline-powered vehicles in the range of 25-30 MPG US In the United Kingdom, Germany, Japan and Italy, they are as good as the best gasoline hybrids in the range of 45-50 US MPG But in carbon low supply places, like France, Brazil, Switzerland and Norway, they are in a different league, averaging well over 100 MPG US for equivalent emissions.
It is important to remember that the electricity you get may not match your national average for all sorts of reasons night The intensity may vary, you could have solar panels or live in a country like the States united, wherein the gate is actually a group of for example separate gates in Colorado an electric powered car gate is equivalent to about 30 MPG US while in California, it is around 70 US MPG.
For all comparisons in this vehicle manufacturing map of a gasoline car is just 40g CO2e km compared to an electric vehicle 70g CO2e km for the reason is that we have taken into account both a larger footprint manufacture and mileage of less than life in an electric car.
If you are interested in the details in the full report, it includes a breakdown of all the numbers, the sensitivity to manufacturing, vehicle performance and comparisons to diesel vehicles.
Critics of electric cars like talking about manufacturing emissions and put the horses before carriages, but they never seem to offer better solutions if they had flown lyrical about urban densification, transit electrified and the joys of bicycle criticisms would ring true, but that's not what you hear.
Electric cars are relatively new commercial scale and address cost issues, the scope and speed charge Everyone who will be helped by improved batteries Despite this, they offer great hope to reduce carbon emissions, improving air quality and reduce noise pollution.
Electric cars are far from perfect, and there are many valid ways to criticize But do not pretend that's gasoline vehicle can compete with an electric car in terms of carbon emissions is simply not a contest.
Giving an electric car right juices and crushes combustion engines.
Author's note in case you are wondering, I don t have an electric car we have an effective Skoda diesel is mostly used on weekends with 4 people in it my preferred mode of transport is my old Dutch bike, which in terms of gCO2e km trashes all comers foodprint included.
I would just like to specify some informations 1 3 million electric cars in the world in 2015, but they have the highest emissions of greenhouse gases if they were fueled by gas or diesel I analyzed data from carbon footprint and the numbers of the EV industry More than half of electric cars the world are the US and China, two countries where electricity is mainly from coal, respectively 40 and 80 thus produce electric cars there more carbon than their thermal equivalents in 2015, electric cars produced there are 250 000 tonnes of CO2e than if they were done by gas or diesel.
Someone somewhere forgot to mention the tons of lithium used in the production of batteries and thousands of liters of arsenic and Cyanide used in industry they still use petro chemicals in the production of the vehicle Nobody ' still has a strategy for the disposal of batteries as they expire so no doubt they will be buried in caves expecting somewhere to self or Combust flee the planet.
Looking at buying a specialized vehicle such as an EV metro vehicle base How can I use for normal movement and use it as an SUV or pulling a trailer or normal use of a vehicle that I have found that all electric vehicle owners who live outside a 3-4 mile daily car use more all must have a gasoline engine for backup to do normal activities that we all How using the footprint How can we afford to own what is at best a specialized vehicle such as EV to use when the work average journey is more than half the distance of the EV charging capability as ever, did it true that even the best systems charge the battery is about 80-90 effective If my batteries need a recharge of 10 kW-hr I have to put in 12 kw-hours also play on the life of the battery capacity loss is about 50 more than 5 years of driving 12,000 miles YR real data, not going out of hype production If I get only 75 miles per full charge, and the charge takes 10 hours to deliver my car is parked and supports 1600 hours 2 full months of the year charging stations are the parking space most non-green in the world and some even try to use solar panels charge with footprints and a very poor green solution to the use of coal or oil to load their vehicles to electric vehicles need much better batteries and more beach, in combination with a central power source as green energy nuclear before electric cars are ready for prime time and take more than a permanent auto market that they are far away and Bio diesel vehicles hydrogen were once thought to be the saving grace, electric vehicles are going the same way if you want convenience, low cost, low carbon, buy a gallon gas vehicle 65 mile and release the odious waste of parking spaces by owners of privileged electric vehicles that have been subsidized by taxpayers in cities is atrocious If you want to go green and buy a bike and ride to work those few miles.
CO2 production as a measure of efficiency is absolutely not what any engineer or even a physics student school would use to determine the effectiveness of a particular system a well documented system and researched like burning and electric motors.
You say its bad mathematics, but there's no mistake that the best way to determine the effectiveness, in all its complexity as it is already on a swap basis, would be to take PHYSICS AND VERY STANDARD irrefutable considering the power out, the engine load, energy loss, and you must take into account the overall production of materials and maintenance and forecasting in the accounting for future production efficiency, etc.
The physical difficulties and considering the production of power plants, the efficiency of combustion engines and reaction equations, chemical reactions and thermal dynamics, supply chain management, and many other things can and occupy a competitive market with real considerations, but CO2 emissions as a determinant would be the underdescribe effective because it didnt have anything to do with efficiency or would be astronomically by many because of chaining relationships ill effect including who would be considered in meteorology climate change.
Ultimately, it would be very easy, although perhaps a long time to find and crunch those numbers and display them on your website in an easy to digest with reference sources I suspect that you won t do that in the near future.
What happens to the price of oil, gas and coal in China at America stop use You know, China, where they donate t EPA and don t really care if they are invited to your evenings wine tasting.
I want to thank you all in these discussions to virtually eliminate my concerns for the environmental impact of EV's I was a skeptical because mainstream media has not bothered to prove or at least maintain EV comparisons to supply electricity carbon footprint must come from the same sources that some of our gas guzzlers right where skepticism the second part of my concern was towards the end of the life cycle of electrical batteries particularly lithium ion vehicles J have always been pro clean energy and will now add EV's in this equation.
I have a question it was stated that the loading of e-vehicle is more efficient than using a gas engine Figures for the load of e-vehicles are straight-forward, but do not represent the unused power that continues to generate even if you do not use it, it's there full-time for your convenience Yes, you pay more per kWh in money to cover the cost, but my question is; how wasted energy that you have not used yet been produced, is included in the actual total energy used to charge your e-vehicle.
This is a wrong item Although plant uses fossil fuels, electricity can be delivered overnight charging EVs waste power plants fossil fuel electricity even if nothing consumes power by idling , so the use of electric vehicles may possibly reduce the use of fossil fuels.
How to include the production and disposal of batteries in the overall environmental impact.
Read Lifecycle Analysis Comparison of electric vehicle battery and a conventional gasoline vehicle for yourself is the junk science Given the wildest assumptions of energy with a green thumb on the scale, this study assumes a sum exorbitant mile 180k break even point of CO2 emissions between a leaf and a Versa a guy who managed to get his 100K miles sheet says he only has a range of 36 miles and can t drive during the month winter all electric cars are a scam I want to continue Nissan for false advertising, for example zero emission versa is half the cost of a sheet, and taxpayer money to help people buy the sheet will be poured easily last 250k miles, and have more than 400 miles long range after the sheet gets 3-4 change the battery and only 75 miles away.
