In a bid to fight global warming, reduction of emissions to the atmosphere was cited to be the most impeccable solution. Many techniques and scientific innovations have been put up by some of the world’s brilliant minds, ranging from creating all sorts of electric vehicles to converting carbon dioxide to concrete through the intervention of 3-D printing. Very interesting and truly inspiring, isn’t it? Well my innovation is also in the pipeline, I saw what global warming did to the ice cover in Antarctica and how that white bear was suffering. The point is everyone has a role to play, It’s either we stand now and fight global warming or our grandchildren live amid the direful calamities of the time.
There are various ways in which companies are endeavoring to reduce the carbon footprint, as stated of particular interest in this article are the electric vehicles. What are they? Do they work when power goes off? Are they the heaven sent solution for the world’s emissions problem and hence warming of the globe? During the spring school in Germany, I and fellow energy students had an opportunity to attend a presentation by one of the electric vehicle (EV) specialists from Ford, I must say it was one of the best I have ever had about cars, one of those presentations where you feel everything has been driven home thoroughly and in the end the only question you’d ask is, “How are you?” – You know what am talking about. Some of the important points to note about EVs other than being expensive is, they’re of different types; Hybrid Electric, Plug-in Hybrid Electric, Battery Electric and Fuel Cell Electric. Those with hybrid systems use both gasoline and electricity while those without use electricity entirely and for that matter you need some charging. As I mentioned earlier these cars are quite not cheap until recently when Tesla, one of the company gurus in the EV field unveiled the Tesla Model 3 Electric car. It is said that this is the cheapest of its kind and goes for 35,000 USD. More than 200,000 customers forwarded orders, it’s cheap after all- its ok you might want to disagree with me on that. This is good news for the company (definitely they're making profits) and the world at large because at least the prices of the EVs are falling to the ones seemingly affordable.
Back ground check, according to IPCC the transportation sector (14%) is in the fourth position after industry sector (21%), agriculture and land use (24%), electricity and heat production (25%) respectively, among the contributors to the global greenhouse gas emissions. I believe by these figures you can imagine how much emissions EVs are saving this beautiful world. Well you might need to rethink meticulously through it, now one would argue it out and jump to a conclusion that they don't use oil, and hence they're clean. But remember, you have to charge them and you need electricity to do that. What are the sources of that electricity for charging? Don't EVs fortify the need for more energy to fuel them? Doesn't this have an impact on the amount of fossil fuels like coal to be burnt to support the growing industry? I mean processing and manufacturing of all the kinds of cells and the vehicle materials, how much more emissions are produced? Should we say that all these emissions are compensated by the time they spend in use after manufacture? And if so, are we not biting our tails? Yes, EVs do probably contribute to the reduction of emissions but to what extent? It's possible that a bigger carbon footprint is left by these cars in the long run than the conventional cars. Let's say that is true, aren't there ways to perhaps reduce the emissions by the conventional cars and making them more efficient? May be there is or may be there isn't but it’s challenging to know now because the focus of the world on such is being shifted and oriented towards more lucrative choices. It's not evil but if in any case it involves sacrificing the generation of our children and grandchildren for profitable choices now, then it is. I think our main focus as the world should be on how to change the energy sources and use environmentally friendly sources, along with finding efficient ways to use the available energy other than looking for more ways to consume it. It’s important that we don't jump the queue of the energy chain. “I am very little inclined on any occasion to say anything unless I hope to produce some good by it” – Abraham Lincoln, I hope this write up triggers some good thinking in you about Electric cars.
