And at a first look the numbers are indeed impressive. According to information by the authority, the six cars save 3,096 litres of liquid fuel per year, and emissions drop by 5.52 tonnes.
The engineers explained how they calculated this amount, and it makes sense. It turns out, however, that one crucial calculation is missing – how many carbon emissions it takes to produce the energy required for charging the six electric vehicles, which are powered through the main grid.
Their analysis is specific as far as it goes. The engineers didn’t just compare their new cars to any average car, but to petrol cars similar to the Nissan leaf model and Ford Fiestas, which are also new. They also took into account how many kilometres the average car belonging to the company travels per year.
This helps when calculating the savings in petrol. Comparing the electric cars to the Ford Fiesta 1.5 saloon which uses 5.16 litres per 100 kilometres, they estimated an average car in their possession travels around 10,000 kilometres, meaning the six cars have indeed a saving of 3.096 litres.
The emissions can also be calculated. The CO2 emissions of the Ford Fiesta are 92 grammes per kilometre, which are multiplied by the amount of kilometres and the number of vehicles, thus adding up to 5.52 tonnes per year.
So far, so good. But those six electric cars need charging and that takes electricity, and Cyprus’ electricity is largely powered by oil and oil means high carbon emissions.
When one considers the amount of carbon emissions for 2016, which the authority says is 0.00074 tonnes per kW/h, an engineer and expert in renewable energy sources came up with the figure of 6.669 tonnes per year for the 10,000 kilometres of travel. And that is way more than the emissions saved by the purchase of the new cars in a year.
According to the electricity authority, however, this last calculation is not that easy to make. “Every day our transmissions operator decides on a different combination of energy sources, and the amount of crude oil, renewables and gas oil varies,” spokeswoman of the EAC Christina Papadopoulou said, “how can somebody calculate the amount?”
The company also pointed out that its engineers have calculated the saving of emissions using the example of new cars. Older models emit more than the 92 grammes used for the calculations, thus the savings may well be more than 5.52 tonnes.
According to EAC engineer, Marios Papouttis, the emissions for the electricity generation will get less over time. While only 9 per cent of electricity is currently produced by renewable energy sources, this this percentage will increase considerably in the future.
Even having this in mind, electric cars are certainly not yet those wonderfully clean machines so often claimed in many countries where they tend to be hailed as the answer to all that is bad about cars.
As EAC chairman Andreas Marangos said when announcing the acquisition of the authority’s electric cars, increasing their numbers is an international trend. In Europe, he said, France and the UK have already announced timeframes concerning the exclusive use of electric cars.[…]
The Cyprus Electricity Authority (EAC) has received its first six electric cars to add to its fleet which it says will contribute to reducing the country’s carbon emissions by 5.52 tonnes per year, it was announced on Tuesday. The utility also said that it has set up another e-charge station in Limassol, bringing the total […]

Transport minister Marios Demetriades said on Monday that speed cameras should be installed as soon as possible. Speaking after a meeting with the Road Safety Council (RSC) he said that after he has consulted with the finance ministry, a meeting will take place to find a practical way to install the system, which will significantly […]
Satellite imagery – that was used during a legal proceeding – has exonerated a motorist from speeding and dangerous driving charges at a Nicosia court.
According to state prosecutors, the motorist had been clocked driving at 95km/h in a 50km area along Archbishop Makarios III Avenue in the early hours of June 2, 2013.
When he was waved down to stop, police claim that he instead continued on his way, switching lanes and entering the lane for oncoming traffic which were waiting at traffic lights for the light to change to green. Undeterred, he continued to pass them and drove through the traffic lights – which were red at the time – before finally making his escape.
A police officer had testified that he first noticed the car at 300m and clocked his speed at a distance of 271m. Following standard procedure, the speed of the vehicle was recorded by radar in a straight line from the position of the officer in relation to the position of the car.
The defence attorney, Yiannis Nearchou, produced satellite images of archbishop Makarios III Avenue and showed that the policeman’s statement were impossible as a straight line from his position at 271m, either at the side of the road or up to 2,5m into the road, from the position of the car would have placed it in the opposite lane.
At 300m, the car would have been on the pavement on the opposite side of the road.
Judge Pavlos Kyriakides went on to find the defendant not guilty saying that he could not safely accept that the policeman’s testimony as being reliable.
THE state health services presented a unique mobile phone application for ambulance calls on Wednesday, which they say is the first in Europe, which can track and locate a patient and help reduce response time. The software, which will run through the Zoom Cyprus application, was developed free of charge by private companies in cooperation […]
