They are quiet, comparatively inexpensive to run and gentle on the environment. So why don’t more people drive electric vehicles (EVs)?
These emissions-free vehicles are seen as the future of transport, yet despite their potential to help the world decarbonise, global sales have been slow to gather momentum.
That is not to say sales are not increasing. Around 4,3 million new battery-powered EVs (BEVs) and plug-in hybrid electric vehicles (PHEVs) were sold globally in the first half of 2022. BEV sales grew by 75 percent on the year and PHEVs by 37 percent. And more growth is predicted for the rest of 2022, with sales expected to rise by 57 percent on the year to 10,6 million.
Policy makers in several economies have set dates to phase out the sale of petrol and diesel cars. An EU-wide ban on sales of these cars will come into force by 2035, while the UK has brought its own phase-out date forward to 2030 from 2035. China — the world’s biggest car market — is aiming for 40 percent of vehicles sold in the country to be electric by 2030.
As the world moves towards stricter emissions targets, there are questions about whether the global switch to EVs is happening fast enough and on a big enough scale.
A recent RAC survey in the UK shows just 14 percent of drivers plan for their next car to be electric, up from 10 percent in 2021.
However, the number of drivers expecting to get an EV in the next five years dropped from 17 percent to just 15 percent over the same period.
Reluctant to make
the switch
These are the three main reasons why people are reluctant to make the switch from fossil fuel to battery power.
High upfront costs of electric vehicles
While electric cars are often much cheaper to run — as much as half the cost per mile — than similar-sized petrol or diesel vehicles, they are also generally more expensive to buy.
The cost of charging an electric vehicle depends on where, when and how it is done.
EV owners with charging facilities at home can take advantage of cheaper electricity rates, especially during off-peak hours.
Costs increase significantly when drivers use public chargers. Rapid or ultra-rapid chargers can push per-mile costs close to or above the running costs for petrol or diesel cars.
Limited access to charging infrastructure
A lack of public charging infrastructure is the main barrier to EV adoption globally, according to a recent study by professional services company EY. As the chart shows, more than a third of survey respondents cited insufficient access to city charging points as the main reason for not switching to an EV.
This supersedes concerns about the high price tag of an electric vehicle, which was the previous leading barrier to adoption.
While home-charging is an option for people living in properties with garages or parking spots, people without on-site parking have to rely on workplace or public charging facilities, which are unevenly distributed and can be a costly option. The RAC survey in the UK found around a third of UK drivers do not have any way of charging an electric vehicle at home.
Most electric vehicle owners do charge their vehicles at home or at their workplaces, but the number of available public charging points increased by 40 percent in 2021. Globally, there were around 1,8 million available in 2021, including around 600 000 fast-charging points.
Concerns about EV range
Range anxiety — worries about the distance an EV can travel on a single charge — is another main barrier to electric vehicle adoption.
Around a third of drivers from around the world say they are concerned about driving long distances in electric-powered cars, according to the EY survey.
An EV’s range largely depends on its battery capacity and motor efficiency, but it can also be influenced by factors like the weather, driving speed and whether the vehicle is operating on city roads or an open highway.
Compared to the distance a vehicle with an internal combustion engine can travel on a full tank, EVs have some way to go to close the gap — although EV ranges are increasing. Advances in battery technology have seen the average EV range more than double in the last decade, from 138 km in 2011 to 349 km in 2021. This compares to 665 km for an average fossil-fuelled car in the US.
The road ahead
Battery technology has an increasingly important role to play in efforts to decarbonise transport and in other parts of the energy transition.
The World Economic Forum has brought together 42 manufacturers, raw materials producers and other organisations as part of the Global Battery Alliance, which seeks to establish guiding principles for a sustainable battery supply chain by 2030.
Efforts to establish a sustainable battery industry could halve the greenhouse gas emissions of batteries by the end of the decade.
Success here rests on establishing concerted, targeted and bold public-private sector collaboration, according to the Alliance. — World Economic Forum
