Envision. Build. Grow


The future is here and now! We are approaching the peak of the fourth industrial revolution (4IR), where there is a fusion of advances in artificial intelligence(AI), robotics, the internet of things(IOT), genetic engineering among others .And  the fact that we have advanced from a steam powered engine to gasoline powered engine and now a Lithium ion battery powered engine is just outstanding. Indeed ‘Any sufficiently advanced technology is indistinguishable from magic’ (Arther C. Clarke, 1962)

Electric Vehicles (EVs) are powered by batteries as opposed to the normal use of diesel and petroleum. EVs convert over 77% of electrical energy from the grid to power the wheels. Conventional gasoline vehicles have an efficiency of not more than 30%.

More than two thirds of carbon emission of an EV is produced during the manufacturing period of the Lithium Ion batteries. However the technology of manufacturing the batteries keeps on improving.

EVs need to be recharged constantly, although depending on the model, most can travel up to 300 miles on a charge. There is need for charging points and charging takes an average of 30 minutes to 12 hours depending on the battery size.

EVs are consequently more than 7 times cheaper to maintain as compared to normal gasoline cars.

Advantages of electric cars on the environment

Due to the fact that they produce no carbon emissions, EVs (Electric Vehicles) greatly help in the reduction of environmental pollution. CO2 contributes majorly global warming through greenhouse effect. In over a year, just one electric car on the roads can save an average of 1.5million grams of CO2 (which is equal to four return flights from London to Barcelona). Most governments such as the US and UK are intending to ban the sale of petrol and diesel cars by 2040 and therefore fully embracing use of EVs.

What’s more, EVs can also help with noise pollution since they are far quieter than convectional vehicles. This is due to the fact that oil based vehicles operate on the principle of internal combustion engines. In fact the only noise that comes from EVs is caused by their tires or generated by wind resistance.

Some models of EVs have their own solar PV(photovoltaic cells) attached to their body making them able to utilize renewable energy.. This enables them to charge their own batteries during the day using solar energy. Thus consequently this effectively makes them cheaper to maintain. The graph below illustrates the growth in sale of electric vehicles from the past few years and the rate is expected to grow exponentially for the next 20 years.
