Go Electric- A step towards Digital India






In this Modern era, every common man has a necessity of having his/her own private car or bike. Almost in Mumbai every Middle class family have their own vehicle which they use it on daily basis. Which has resulted lot of effects on our atmosphere and has led many new diseases and health issues grow on human beings. Also this has resulted the increase in usage of petrol and diesel. Today, the stakes of petrol and diesel have almost touched near hundred per litre which has made very difficult now to afford for a common man. Petrol and diesel always have a debate of who being more harmful for the environment.

Diesel engines emit less CO2 and greenhouse gases than petrol engines. This is because of the type of the fuel and the internal efficiency of the engine. More specifically, the fuel used in diesel engines has a higher compression ratio than petrol and it also performs better than petrol engines. As a result, less fuel is used to travel the same distance, which allows to save more of CO2. However, things are not that simple because the discussion of spreading the idea that diesel cars pollute less than petrol cars. There are other few reasons where petrol outperforms diesel. Indeed, diesel engines have the uniqueness of requiring large amounts of air for fuel combustion. But the major problem with this air is that it causes more chemical reactions, which release significant amounts of air pollutants. Initially, when the first diesel engines arrived on the market, they were significantly less efficient than petrol engines in terms of fine particles. They emitted much more fine particles than gasoline particles. Since then, manufacturers have installed particulate filters to deal with the adoption of new, more restrictive standards on diesel particulate matter pollution.

Despite being able to filter a huge amount of fine particles, these filters cannot retain the finest particles produced by diesel engines. The pollution issue is still a bit more complex than what we have been discussing. Firstly, because the technologies of these engines evolve fast and secondly, because petrol and diesel vehicles are often quite different, both in their structures and in their uses. Also in recent years, a system called direct injection has gradually spread over petrol engines. This system uses a pump to spray fuel into a cylinder at high pressure to reduce fuel consumption. But the problem of this system is that it increases the number of fine particulate pollutants in petrol engines.

The problems becomes more complicated with the different models, as well as different uses of petrol and diesel vehicles. It has also been proved that diesel vehicles are bigger, heavier and more efficient than petrol vehicles. They are also used more frequently to travel greater distances. But, on an average diesel engines pollute more than petrol engines in terms of CO2 emitted over their life cycle. To speak the truth, the only engine that really helps to reduce both CO2 emissions and fine particle emissions is, especially if powered by renewable energies, the electric motor.

Rather than spending tones on consumption of diesel and petrol and increasing pollutants in the atmosphere, people should rather turn their priorities towards CNG cars & Electric cars. To be honest every usage has a dark and a lighter side. But by using CNG & Electric cars there will be lesser harm to the environment than the damage which is caused by Petrol & Diesel vehicles.

Charging at home or using public charging points like the ones in malls is more convenient than enduring the long lines at petrol and diesel. Changing the gears and managing the clutch can get quite exhausting, especially in heavy traffic. Electric cars have no clutches or gears, so one can have a smooth ride while driving. Most importantly there are no vibrations and no engine noise, so the ride is super quiet. But, Today there are few variants in vehicles which don’t have gears and clutch, they are fully automatic. Talking about electric emissions they emit less CO2 than CNG, Petrol & Diesel. The electric cars are powered by grids that run on coal, which is as dirty as it comes. Also it can be an option if one is using solar power vehicle, then a vehicle can run on nearly clean energy. CNG Cars emit far lesser CO2 emissions than Petrol & Diesel vehicles whereas electric cars even though powered by a coal-powered grid, emits far fewer emissions than a CNG car.

A CNG car is an alternative fuel car which is opted by most of the people in this modern era. It uses Compressed Natural Gas (CNG). Here energy is released by combustion of essentially methane gas (CH4) fuel with oxygen (O2) from the air to carbon dioxide (CO2) and water vapour (H2O) in an internal combustion engine. As we all know methane is the cleanest burning hydrocarbon and many contaminants present in natural gas are all removed at source. Convenient and cost-effective gas storage and fuelling is a key challenge if we compare it with petrol and diesel vehicles as natural gas is pressurized and in case of LNG, the tanks need to be kept cool. The lower energy density of gases compared to liquid feels is mitigated to a large extent by a high compression of gas but results a trade-off in terms of size & weight of the storage container. Even though it occupies the space of luggage it is much more cheap than that of Diesel & Petrol vehicles considering the high stake in prices in today’s modern world.

Also a key advantage of using CNG Vehicles is that Methane today mostly comes from non-renewable sources but can be supplied or produced from renewable sources, which offers net carbon mobility. Indeed the lower operating costs and government incentives to reduce pollution from heavy vehicles in urban areas have driven the adoption of NGV for commercial and public uses i.e. trucks and buses. Despite its advantages, the use of natural gas vehicles have some disadvantages too, including fuel storage and infrastructure available for delivery and distribution at fuel stations. CNG must be stored in High pressure cylinder which is not that easy. CNG tanks are usually located in the vehicle’s trunk or pickup bed, which reduces the space available for other cargo. This problem can be solved by installing tanks under the body of a vehicle or on the roof, which leaves cargo areas free. But it increases the risk of fire getting attracted and the vehicle getting exploit if the tanks are installed under the body of the vehicle.

Today, there is a rise in usage of CNG & Electric vehicles in the world. But, in India electric vehicles are not used effectively. But Electric cars even though are costly to purchase at first but are relatively cheaper than CNG & fuel vehicles later. Electric cars make the air better for breathe. It allows one to skip the Gas stations and ‘fill up’ at home or work. This also reduces particles of pollution in the air which is really very important in India specifically as considering the amount of increase in usage of vehicles and population too. Electric cars are the future scope of transportation. Maintenance is relatively way too low than Gas & Fuel vehicles. Also considering the noise issue, electric cars are quiet inside and outside. If you live in big city like Bombay it will have a major impact if vehicles don’t create any noise. Considering the performances electric cars provide a great performance to the customers. Recent electric vehicle models are making huge gains in range performance it is possible just because of advancements in battery technology as well as electric regenerative systems in vehicle braking.

Thus, I personally feel that CNG & Electric usage of vehicles should be immensely increased and in India the variety of electric vehicles should be increased too so as to take a step forward towards making India a Digital One. Also I would suggest our Government to invent Electric two-wheeler vehicles too which will widely help to protect the environment from pollutants and much more harmful particles.
