Yes, people usually call this "Full lifecycle analysis". It takes about as much electricity (or energy) to refine a tank of gas as to charge an EV, so there isn't necessarily an increase in load on the grid by electrifying transport. However some energy generation used by refineries that isn't electricity from the grid would have to get re-arranged.
Anyway maintaining a more robust grid should be much cheaper than maintaining thousands of gas stations and the trucking routes used to keep them filled up.
In 2019, the world seaborne trade volume reached about 11.08 billion tons. Out of this, crude oil, oil products, and gas accounted for approximately 32.5% (3.6 billion tons) of the total volume. Coal made up another 8.4% (935 million tons). In total, energy products represented around 40.9% of the global seaborne trade volume.
It's important to note that these figures are from 2019, and the percentages may have changed since then due to various factors, including evolving global energy markets, fluctuations in demand, and the transition to renewable energy sources. The percentage may also vary depending on how you define "energy products."
