There are currently around 200 million electric vehicles on roads worldwide. This number is expected to grow by more than a factor of 10 by the year 2040. With such growth, the demand for electricity will have to increase accordingly. Since it is not possible for every single house or business to store large amounts of energy, the only option would be to increase production
capacity. There are several factors that will determine how much of a supply we can expect from electric cars and how much electricity they require in the future. We will look at some potential scenarios and evaluate their impact on production capacity and grid requirements.
Production Scenario:
The scenario that we will be exploring above is based on the assumption that the production of electric cars will rise rapidly, particularly in emerging economies such as China. In fact, forecast data from Bloomberg Ne
w Energy Finance predicts that the production of electric cars could increase from today’s level of more than 200 million up to 1 billion units by the year 2040. This would require an enormous expansion of production capacity, not just for battery cells, but also for charging ports, and EV ‘infrastructure’ such as power grids, roads, and public charging stations. We will examine the impact of this massive growth of electric cars on supply in two different scenarios. The first scenario assumes that the growth in production capacity is limited to the needs of current electric cars, while the growth rate is expected to increase to meet the demand of other new vehicles. The second scenario assumes that the production capacity is increased to meet the demand of all new electric cars. Growth in the demand for electricity will follow the same path in both scenarios.
Batteries Require More and More Power to Be Charged
One of the challenges that will face EV industries is the growing demand for power to charge EVs. It is not feasible to charge batteries with solar power alone, so the only other option would be to build large power grids to support this demand. This will increase the grid requirement in a significant way. According to the International Energy Agency, the demand for power can rise by an average of about 10% per year, with a high variability around this average. This demand will rise to account for the increasing EV usage and could reach 2,000 TWh by the year 2040. This huge increase can be attributed to the expected increase in EV adoption. By the year 2040, the global EV population is expected to rise to around 3 billion. EVs can be charged with a variety of power sources including solar, wind, hydroelectricity, and even coal power. However, in most places, the availability of these sources is not uniform. EVs can also be charged using high-voltage transmission lines. However, this power source is limited in the number of locations where it can be deployed.
New Vehicles Produce More Electricity than Others
All the factors discussed above lead to an interesting, yet straightforward conclusion. Electric cars themselves could become a huge contributor to the electricity grid. The production of batteries for electric cars becomes a major source of electricity. The batteries of an electric car are expected to store about 60-100 kWh of electricity, which is more than the average daily consumption of a household in many countries. With such a significant contribution, the production of batteries will not only have to meet the demand of new car owners but also other new consumers such as ride-sharing companies. In fact, the production of batteries for electric cars has already surpassed the production of wind turbine blades. As the production of batteries for cars becomes more and more competitive, it will lead to significant increase in the supply of EV batteries.
Grid Requirement Increase From New Vehicles
EVs are expected to play a significant role in the growth of electricity demand. However, the transition to electric cars will not happen overnight. As consumers get accustomed to electric cars, they will start to adopt EVs as a mode of transportation. This transition will take time, which will lead to a relatively slow adoption of EVs. In the meantime, the demand for electricity will increase with the increased number of electric cars on the road. The average driving distance will increase with the adoption of EVs. This will lead to an increase in the voltage and frequency of transmission lines, as well as an increase in the demand for transformers. The increase in the demand for transmission lines can be satisfied by an increase in the number of high-voltage cables. The increase in the demand for transformers can be satisfied by increasing their capacity.
The Bottom Line
The rise of electric cars presents a great opportunity for renewable energy technologies to transition to a more prominent place in the electrical grid. With the growing demand for power, it will be necessary to expand power grids due to the increasing demand for high-voltage transmission lines. The transition to electric cars will lead to an increase in the demand for electricity, which will require an expansion of power grids. With a projected increase in electric car production by 2040, it is possible that the demand for electricity could rise by a factor of five. It is important to prepare for this transition by expanding power grids and developing more efficient technologies for power distribution.
