A new study by Imperial College London has revealed that electric vehicles (EVs) emit on average as little as one quarter of the CO2 produced by conventional petrol and diesel cars.
If the manufacturing of batteries is taken into account this figure rises to one half. The CO2 emitted in producing batteries for the most efficient EVs would be saved after just two to three years of running.
As Britain’s electricity supply is being progressively decarbonised, the CO2 emitted by EVs could fall to one tenth of that produced by petrol cars in five years’ time. 55% of electricity demand is already being supplied by wind, solar, biomass and hydro.
The number of EVs in Britain is increasing by 30% a year and has now reached well over 200,000. One in 40 cars sold in the UK are electric with a third being pure battery models and two thirds being plug-in hybrids.
The long-awaited replacement to the Feed-in Tariff – The Smart Export Guarantee (SEG) has begun with some generous, and some less than generous offers on the table.
The 1st January deadline for energy suppliers to offer a payment for exported energy has begun with no fanfare, not even a whisper.
While the Department for Business, Energy and Industrial Strategy (BEIS) was not expecting every mandated supplier to offer “a really, really decent tariff”, the below chart shows disappointing results. In an article published on the Solar Power Portal last year BEIS said they would like to see six-eight suppliers offering a “really good” tariff.
The latest offers can be seen on The Smart Export Guarantee League Table on the Solar Trade Association website.
0% company car tax for April 2020 will drive uptake further.
Despite a stagnant new car market in the UK, electric vehicle sales numbers have soared since the beginning of 2019.
Diesel sales are down to 22.6% with the gap filled by EVs. Sales for BEVs (battery-powered EVs) year to date are 25,072 – a significant increase on 2018s figure of 15,472.
Pixie Energy analyst Tom Lusher said the increased uptake of BEVs is due to the closure of the plug-in car grant to PHEVs (plug-in hybrids) by OLEV (Office for Low-Emission Vehicles). While BEVs still receive a £3,500 grant and developments in EV manufacturing mean prices are dropping.
The introduction of a change to company car tax rates in April 2020 – 0% for zero-emission vehicles from April 2020) will no doubt drive the uptake of BEVs even further.
