So...a bit late to the party.

I do not believe electric cars are the answer that people make them out to be.
Many people think they are but I'm going to put forward some thoughts/observations that will hopefully open your eyes.

The zero emissions story.
Used as a marketing tool. The reality is that they do require more carbon emissions in their production than ICE (internal combustion engines). What most won't tell you is that the carbon emissions have the potential to continue after production. It all depends on what is utilised to generate the electricity that goes into the vehicle. There are still coal powerplants in operation around the world as well as natural gas powerplants. Charging your vehicle with energy generated by fossil fuels will still have harmful emissions... It has simply moved from the vehicle to the powerplant.

Energy efficiency story. Most people believe that their electric cars are more energy efficient than there ICE counterparts. That is true but it ignores the entire picture; and if you take it into consideration it appears to be far less or at it's best on par or very close with ICE.
So locally we use natural gas for electricity generation. Combination gas turbines with exhaust heat recovery have a total thermal efficiency of about 60%. Transmission efficiency is about 80%. Charging the batteries in an electric vehicle has an efficiency of about 80%. The Conversion of energy from batteries to motive force (inclusive of Regen braking) is 80% efficient.
Total system efficiency is down to ~ 31% for electric vehicles. I will admit this calculation is a bit crude but it takes all things into consideration. This figure is even worse if it is a straight gas turbine system without heat recovery. Those have a thermal efficiency of about 30%; if this value is used instead the total system efficiency is now ~ 15%


Have more to write and will edit when I get the chance

Thak you for your post. the only one here since 2018 when i purchased my electric Car.

on the point of zero emission, i know the manufacture process creates esmissions however not all the electricity that poweres the car has to be generated by fossil fuel. As solar and wind farms can generate electricity. therefore this gives the opportunity for much less emissions. ICE cars do not present this opportunity AT ALL!

While the energy effenciency conversion is less that that od ICE cars, if we figure out how to use 100% renewable energy, will we cahre about the conversion effenciency?

Secondly

As much as I don't like nuclear... Can't turn a blind eye to the facts stated; and you need a holistic view on all factors when making a decision.

Hydro is out in Trinidad
Solar is only dependable when the sun is out. The panels are usually constructed with heavy metals and carcinogenic chemicals which aren't easily handled or disposed.
Wind needs land space and is also inconsistent.
Wave; depends on wind actually
All these are not energy dense.

My thinking is to not create more problems in coming up with solutions.

the East coast faces the Atlantic Ocean, we could utilize this, however i feel only when a private company initiates this.

Love how the tesla share reach 900us it was 190us in may 2019

It is obvious that evs are making traction

The UK plans to ban sales of all ice vehicles by 2035

I hope I will one get a chance to buy one from a local store

I will do the tesla stretch and pay extra than I would normally pay for a vehicle

Tesla make fantastic vehicles

LONDON — Britain will ban the sale of new gas, diesel and hybrid vehicles from 2035, five years earlier than planned, in an attempt to reduce air pollution and fossil fuel emissions, the government announced on Tuesday.

Britain's step amounts to a victory for electric cars that if copied globally could hit the wealth of oil producers, as well as transform the car industry and one of the icons of 20th Century capitalism: the automobile itself.

The U.K. isn't alone in its efforts. More than a dozen countries around the world have announced plans to crack down on new sales of gas and diesel vehicles in the next decade or two. France plans to ban the sale of fossil fuel-powered cars by 2040 and Norway's Parliament has set a non-binding goal that by 2025 all cars should be zero emissions.

In addition to bringing forward to the date of the ban on new sales of gas and diesel vehicles, the government also included hybrid vehicles in the ban for the first time. It said that it would bring forward the date even closer if it is possible.

Last year, the U.K. pledged to cut its greenhouse gas emissions to net-zero by 2050, one of the most ambitious targets of any leading economy. The ban on sales of new gas and diesel vehicles fits into that goal.

"We know as a country, as a society, as a planet, as a species, we must now act," said Prime Minister Boris Johnson at a launch even for a U.N. Climate Change Conference planned for November in Glasgow, Scotland, known as COP26.

According to experts, the targets of countries to ban sales of new gas and diesel vehicles won't be effective without accompanying action.

"Those targets need to be complemented by whole range of measures at the national and regional level, such as informing consumers about the vehicles on offer or building of the necessary charging infrastructure," said Peter Mock, managing director of the International Council on Clean Transportation in Europe.

In Britain, diesel and gasoline models still account for most new vehicle registrations in Britain. However, registrations of electric vehicles rose 144 percent between 2018 and 2019, according to the Society of Motor Manufacturers and Traders.

Hello everyone. What local companies currently offer electric cars (not hybrid) for sale and what models are currently registered (on the road) in TnT?
