Nuclear power suppliers today face a challenge that has remained unresolved for decades: nuclear waste. This waste can remain radioactive for hundreds of thousands of years and can contaminate the environment if not disposed of properly.
While fleets are concerned with the procurement of EVs, energy suppliers are concerned with ensuring the grid can even support such a large increase in demand. The US Department of Energy estimates that electricity consumption could go up by 38 percent by 2050 due to the transition to EVs. The challenge now is generating enough clean energy to support this change.
Jersey City is set to build the first self-sustainable municipal microgrid in the country that will power the city’s EV fleet and electric refuse trucks and save taxpayers over $21 million over 20 years.
Together with the transition to electric vehicles, comes the need for clean, renewable energy sources. It is projected that renewable energy will be the largest electricity source by 2050, as the world moves to completely phase out fossil fuels. With more fleets looking to take on EVs, it is essential to also consider how these EVs are being powered and whether it is a clean, sustainable practice.
There are many factors to consider when it comes to making EVs more sustainable at every life stage. When broken down from raw material extraction to vehicle disposal, is clear to see that EV’s zero-emissions claim is really only true in operation.
Solar energy has grown rapidly in the past decade, reaching 97 gigawatts of capacity by 2020 (enough to power 18 million homes). Though only 11% of the renewable energy consumed in the US is solar, this figure is expected to more than double by 2050.
As every state has varying grid capacities, and differing patterns of consumption during different times of year, grid operators will have to carefully manage energy consumption. Considerations will include seasonal changes in electricity use, peak and off-peak usage times throughout the day and whether purchasing electricity from other states could be an alternative solution.
