Why Aren’t We All Driving Electric Vehicles?

eco-friendly-car-repairs

The Toyota Prius, which was released in 1997 was the catalyst for a small green consumer segment around the globe for hybrid technology, creating and spurring the hybrid vehicle niche. Hybrid-electric vehicles (HEVs) have experienced a significant rate of growth in the last 10 years. We now not only have available HEVs, but also battery powered electric vehicles (BPEV), which together represent opposite ends of an electric vehicle (EV) spectrum. The HEV uses an internal combustion engine (ICE) exclusively to power the electric motor; the BPEV uses a battery.

A series drive-train plug-in hybrid-electric vehicle (PHEV) represents a vehicle somewhere towards the middle of this spectrum. It uses a battery for short range driving, and switches to ICE-generated electricity when the battery is depleted. This transformation in technology is regarded as a considerable tipping of the technological scales in the context of an automotive sector, which is typically averse to radical change in the technology of car engines.

This inflexibility can only be highlighted by the dominance of the internal combustion engine over the last 100 years. But what are the reasons for this inflexibility and what is obstructing the revolution against petrol power and the embrace of the electric motor in its various configurations?

Below I put forward that there are three main factors affecting this shift: demand, environmental impact, and political motivation.

Demand

The first and probably the most obvious factor is that of demand. Analysts are quick to point out that market trajectories need to surpass a critical size in order for the electric engine to be economically viable. PSA Peugeot Citroën was the first carmaker to introduce BPEVs in Europe, starting in late 2010 with the Peugeot iOn and the Citroën C-ZERO, but it was unable to reach a critical size for its electric vehicle activities, despite considerable investment and support from local and national governments. The vehicles were broadly regarded as relatively expensive and impractical.

First year sales of HEVs in Europe were 10 times higher than first year sales of BPEVs (about 15,000 vehicles versus about 1,500). Hybrids were appreciated for high fuel economy, which boasted comparable practicality to their ICE counterparts whilst still benefitting from the prestige associated with owning a green vehicle. Analysts hypothesise that somewhere in between these two values may be where the critical size for a market niche on the automobile market lies.

A well-known commentator on electric vehicles, Theo Lieven, conducted a study of 1,152 German individuals, which aimed to disseminate the factors affecting a potential car-buyers’ likelihood of purchasing an EV vehicle on a range of vehicle categories. He found that of 1,152 participants, 5% represented potential EV buyers, with the main factor affecting this difference being the fact that their prioritising of price and performance range was lower than non-EV buyers, and that therefore their barriers in terms of demand were lower.

Some analysts, such as Oscar Van Vilet et. al point out that the total cost of ownership (TCO) of current full EVs are also uncompetitive compared with regular cars and series hybrid cars by more than €800 (£694) per year. At the upper end of the market the current cost of a battery per kWh is around €400 (£347), though battery packs aren’t guaranteed to last the entire lifespan of a vehicle. Even the TCO of future battery powered cars is estimated to be at least 25% higher than that of hybrid or regular cars. This cost gap remains unless the cost of batteries drops to €150 (£130) per kWh in the future. Moreover, complete EV’s require a considerable change in consumerist behaviour. Whereas you can buy an HEV such as a Toyota Prius or a Cheverolet Volt and almost completely avoid changing your driving behaviour, complete EVs require a considerable transformation.

Environmental impact

The second factor that I would like to expound is the effect of EVs on the environment and electricity demands. There seems to be a consensus amongst the academic community that a high proportion of EVs may be possible in the future, based on the capacity of today’s electricity grids. Adolfo Perujo and Biagio Ciuffo (2010) conducted a study of the potential effects of a large scale introduction of EV’s in the private car fleet on the electric supply system and the environment in the province of Milan, Italy. The study was projected for a future date of 2030 using Milan’s current electricity producing capabilities whilst a number of possible EV market trends were considered. The integration of intelligent battery software Elysia in these future trends will become an important factor in managing electricity demands and optimizing environmental impacts.

The results showed that even with a very high future market penetration (20-25% by 2030), the impact of the vehicles on annual energy consumption was negligible, although without appropriate regulation (i.e. intelligent integration, preventing overuse of electricity at a given time) there could be a serious impact on power demands. Perujo and Ciuffo also claim significant reductions in CO2 emissions deriving from a large scale introduction of EVs, though these are only significant within the higher estimates of EVs as a percentage of future fleets and are commensurate with the proportion of renewable and environmentally friendly energy used in a given grid.

Oscar van Vliet et al. (2011) examined efficiency and costs of current and future EVs, as well as the impact from charging EVs on electricity demand and infrastructure for generation and distribution, and thereby on greenhouse gas emissions in the Netherlands. The results of their study bore a number of similarities with the findings of Perujo and Ciuffo. They projected that uncoordinated charging would increase national peak load by 7% and household peak load by 54% respectively, at a 30% EV penetration rate in the vehicle market, which may exceed the capacity of existing electricity infrastructure. However, they anticipate that at a 30% penetration of EVs, off-peak charging would result in a 20% higher, more stable base load with no additional peak load at the national level and only up to a 7% higher peak load at the household level.

Therefore, they maintain that if off-peak charging is successfully introduced, electric driving need not require additional generation capacity, even in case of a 100% switch to electric vehicles. This projection is a lofty claim, and will depend highly upon a number of factors, including the efficiency of the technology available to BPEVs and PHEVs, the success of peak use regulation in the future, as well as the decarbonisation of the electric grid and movement into renewable electricity.

Political motivation

This brings me to my third and arguably most important point of enquiry: the political motivations at play regarding the adoption of EVs. The French and German car markets have seen the most movement towards EVs, though I will apply most focus on the dynamics at play in France, since investment there has been more forthcoming.

Former French president Nicolas Sarkozy in October 2008 at the “Mondial de l’automobile” announced the setting up of a major plan on “véhicules décarbonés” (decarboned vehicles), the president’s speech aimed to promote all clean technologies in automobiles – that is, BEVs, HEVs, and alternative fuel vehicles. Just after the president’s speech and in the middle of the global economic crisis in January 2009, the “Etats Généraux de l’Industrie” (a group of all French industrial actors) was organised in order to create a broad and coherent industrial policy for France.

During this process, financial assistance was decided upon and €3.5 billion was allocated to carmakers, mainly Renault and PSA who each received €1.5 billion. In return, the two manufacturers committed to invest in Research & Development and to preserve employment and production in France. The aim was to protect the French industry from delocalisation and to modernise the national sector to ensure the competitiveness and the dynamism of French factories. The low carbon vehicles plan implemented in October 2009 was designed to promote the re-localisation of production and the creation of a new sector based on electric technology in acknowledgement of Sarkozy’s support of clean automobile technology. To that end, the government agreed to finance a part of the conversion of the factory in Flins (near Paris) to produce the ZOE, Renault’s future main electric car, whose manufacture is supposed to employ new qualified workers. In addition, the plan proposed to attain the conversion of 5% of the current French motor vehicle fleet by 2020, that is about two million vehicles to EVs. It should be noted that France was already in a strong position to embrace EVs from an environmental perspective, since its grid was largely comprised of nuclear facilities, which produce no GHGs.

By comparison, Germany, the country home to some of Europe’s biggest car companies (Volkswagen, BMW, Daimler) has aimed at only half the number of EV’s by 2020 (1 million) even though it collectively produces over twice as many cars as France annually. This could reasonably be viewed as a conservative aim born out of the fact that Germany’s electric grid is still predominantly powered by coal. It should also be noted that as Hildermeier and Villareal point out, employment effects were not at the centre of the German electric car debate, which may have contributed to the more cautious and incremental investment commitment made in Germany.

In France, the plan implemented by the Departments of Industry and Environment introduced a purchasing bonus of €5,000 for the 100,000 first buyers of vehicles emitting less than 60g CO2/km. A collective purchase agreement of 100,000 BEVs by an industrial buyer group led by La Poste (the French postal service) was also promoted. The demand side of the plan focused mainly on the BEV because of its relative marginality in the market. Other levers were concerned with the normalisation and the regulation around charging standards and infrastructure, subsidies for research and development, and investments in charging infrastructures. This process involved numerous actors: civil society (associations), public and political institutions (ministries, local governments, etc.), carmakers, suppliers, mobility operators, electricity providers, and large para-governmental enterprises such as the French mail company La Poste and others like Areva and Vinci.

As we can see, there were a great range of factors which inspired a French surge of support for EVs, including a relatively competent and emissions friendly electricity supply. It can also be argued that without the combined catalysts of economic down turn and a need to bolster the automotive sector and secure jobs, the French government’s investment in EV’s may not have been so forthcoming.

It should also be noted that it was not only direct governmental intervention that mobilised the new embrace of EVs, but that of a whole range of factors which I have mentioned above. Furthermore, the success of the investment remains to be seen. Between January 2010 and December 2012, 14,600 highway capable all-electric vehicles were registered in France. This figure, though promising, would have to increase exponentially over the remaining two year increments leading up to 2020 in order to reach the goal of two million EVs in use within the French private fleet.

Why aren’t all cars electric?

The transition from gas-powered cars to electric cars is a complex issue influenced by various factors. While electric cars are gaining popularity, several reasons explain why not all cars are electric yet.

1. Infrastructure and Charging Stations:

One significant challenge is the availability of charging stations. Unlike gas stations, which are abundant and conveniently located, charging stations for electric cars are fewer and sometimes not as accessible. This leads to “range anxiety” among potential EV owners, concerned about running out of power on long trips or in areas with too few charging stations.

2. Battery Technology and Driving Range:

The current state of EV battery technology also plays a role. Although there have been significant advancements in EV batteries, they still can’t match the range provided by gas cars, especially in cold weather, which can reduce battery efficiency. This limitation affects the practicality of electric cars for some users, particularly those who frequently undertake long trips.

3. Cost Considerations:

The initial cost of electric cars (EV prices) can be higher than gas-powered vehicles, making them less accessible to a broad market. Although EV owners might end up saving money in the long run due to lower fuel and maintenance costs, the upfront investment can be a deterrent.

4. Fossil Fuel Industry and Gas Prices:

The existing infrastructure and economy are heavily reliant on fossil fuels. Gas-powered cars have been the standard for decades, supported by a vast network of gas stations and the oil industry. Fluctuations in gas prices can influence vehicle sales, but the transition to electric models requires significant changes in consumer habits and industry support.

5. Market Availability and EV Sales:

The variety of electric models available in the market is growing, but it still lags behind the diversity of gas-powered cars. This affects EV sales, as consumers often look for specific features or designs that may not yet be available in electric vehicles (EVs).

6. Environmental Concerns and Climate Change:

Despite the clear environmental benefits of electric cars in reducing tailpipe emissions and combating climate change, the transition to electric vehicles is gradual. It requires not only technological advancements in EV technology and charging infrastructure but also a shift in public perception and government policies.

In conclusion, while the future seems bright for electric cars, the transition from gas cars to electric vehicles is a gradual process influenced by technological, economic, and infrastructural factors. As battery technology improves, charging infrastructure expands, and awareness of climate change grows, we can expect a significant increase in the adoption of electric cars, making them a more common choice for the next car or new car purchase.
