ELECTRIC CARS ARE ENVIRONMENTLY FRIENDLY!! Aren't they??





Greetings,
For this weeks article we thought that we would draw your attention to ELECTRIC CARS! You may have heard both car companies and various forms of environmental governments swinging around terms such as ‘we promise that we are investing in green technology’, and these promises will be filled with key words such as ‘higher efficiency, lower emissions, reduce our carbon footprint, environmentally friendly, eco friendly, renewable energy.’ It feels as though the amount of stress put on us to turn to more eco friendly products increase each day. To clear this up we are not belittling switching of that light you don’t need on, or turning of the heating and putting on an extra layer because those efforts help A LOT!, and we do everything we can TO SAVE NATURE AND THE POLAR BEARS, but electric cars being the answer to reducing our emissions… needless to say we are a bit sceptical, so we decided to do some investigating on just how environmentally friendly these cars actually are. Enjoy!


When electric cars are not environmentally friendly:   
Whether a car is environmentally friendly or not comes down to 2 major concerns:
1. How the electric vehicle and particularly the batteries are manufactured.
2. How the electricity, which powers them, is generated.

Based on these concerns it was found that in some circumstances electric cars have a greater impact on global warming than conventional cars. A study conducted in Sweden investigated the production and operation of an electric car driven for 150,000 km through a life cycle analysis. They then compared this to the production and operation of conventional cars. When reading through the study, one of the take home findings was that the energy intensive manufacturing of electric cars meant that some of them make almost double the impact on global warming as conventional cars. This was down to the amount of raw materials and energy needed to build the lithium ion batteries.
Hang on a minute there, the challenges on how environmentally friendly these vehicles are when they have hit the road, is still dependent on how the electricity used to charge the battery is generated within the country.

 


Well our fellow Biobunchers!! Firstly it is important that you are aware of the fact that electricity generated from the burning of coal creates the MOST POLLUTION out of all the other fossil fuels!! And it just so happens that China depends on coal for not a bit but ALL of its energy needs, this drastically reduces the environmental advantage of electric cars driven in China. The life cycle analysis of electric cars  driven in China showed that, they are polluting the atmosphere far more than a conventional car! (just to remind you, this is the exact opposite of what it is meant to do L #sad WHY CHINA WHY??) Anyway… unlike China, Norway seems to be sporting the idea of electric cars, and this is all because most of their power is generated by hydroelectricity. Meaning that their life cycle analysis showed that electric cars driven in their country quickly out performed conventional cars in terms of their environmental impact!

Now, according to Majeau Betlee when the European average generation mix is met, and the your environmental car has been driven for 150,000 km there is a possible 25% improvement on the release of emissions. Sadly the UK does not abide by the European average generation mix . Our energy mix is more coal and natural gas based, so the benefits would be around 10% better over it’s life cycle than a car that has an internal combustion engine. Just to give you an idea on the numbers behind our energy mix: gas (45%), coal (28%) nuclear (17%) and renewable sources (6.6%) compared to the 70% of renewable sources of energy used by other EU countries such as Austria.

All in all, the energy used by the country and their energy mix ultimately decides whether an electric car can be classified as an environmental car. The UK must lower their dependency on non-renewable sources of energy and increase their renewable mix if we are to ever meet our target for the year 2050.
 
So… electric cars are not environmental? 
Well it is safe to say that under the current energy mix exhibited by the UK and mainly China, that green cars are not massively beneficial to our environment. However, there is still hope, by 2020 it is thought that the UK will be increasing the amount of electricity generated by nuclear power stations to 11%, that and the government are placing considerable interest and investment in clean sources of energy.



Now, when one is talking about the environmental impact of conventional combustion engines they talk about that cars tail pipe emission. Surprisingly, when the tail pipe emissions of an electric car are compared to a conventional car, the value is a very surprising big fat. ZERO. Yep you read that right, this means that an electric car emits 100% less through its tail pipe than an internal combustion engine (we here at BioBunch believe that is a pretty big advantage.) It is important to note that the manufacturing process behind the environmental car may not be the best at present, however if there was more of a demand the process would become progressively more efficient. 
It does not end there, of the energy you put into an electric car around 80-90% is converted to useful power at the wheels, compared to a minor 20-30% conversion rate in an conventional car.
CALLING TO ALL LONDONERS!! Have you ever walked through London and thought ‘Is it just me or do we live in an area of really poor air quality’… well to be honest your not far off it, and it isn’t just you. It was found that London is in breach of EU standards on dangerous particles, which are responsible for 4,300 deaths a year! Yeah... that doesn’t sound all too great, but guess what, if more people drove electric cars than the quality of air has a chance to improve all by itself. Interesting how nature has a knack for healing itself without the intervention of humans.
 
And here are a few advantages of electric cars also:
·       Better gas mileage.
·       Less dependency on foreign oils.
·       Reduced exhaust emissions.
·       Saves drivers money.
All in all, we hope to leave you Biobunchers with more knowledge on this advancing piece of technology and the part that electric cars play in both decreasing emissions and reducing climate change. Remember we focused on electric cars in general and not on other cars like hybrids, hydrogen fuel cars and so on. We believe that the effectiveness of environmental cars is based on the countries individual energy mix, however we also take note of the fact that improving a countries transport and decreasing their dependency on buying individual cars has a place in reducing carbon emissions also.

As always guys we are really interested in what you have to say! Do you think that environmental cars have a place in reducing global emissions? Maybe you can think of a solution that hasn’t been mentioned in our article this week? Make sure to leave a comment and keep a look out for more articles!!

  1. After all that glorious history I was kin to know more about Oklahoma and its drilling industry that's why I started looking for more information at online and I found a site that was telling about drilling in Oklahoma and form it I discovered that Oklahoma is paradise for drilling gas and oil because she is well known for her historical oil and gas reserve.

    1. Hi, Sathyam Shonko
      We are so happy to hear that you liked our blog and that you did even more research into the topic of fossil fuels. Thanks so much for the link we were not aware just how big a player Oklahoma was in the crude oil businesses, so thanks again! Hope you enjoy some of our other blog posts on the site.

  8. Green energy is any source of energy that is gathered through renewable ways that do not cause harm to the environment, and the accumulation of the energy can continue indefinitely. A couple of these sources of energy include wind and solar energy. אנרגיית חשמל
