We're talking about dedicated infrastructure, possibly with high-voltage connections and maybe even on-site power generation. It's a whole new ballgame compared to just filling up a diesel tank.

• Number of charging stations needed per site
• Power output requirements for fast charging
• Grid capacity upgrades

Fueling Infrastructure for Diesel

Diesel, on the other hand, has a well-established fueling infrastructure. Gas stations are everywhere, and on-site fuel storage is pretty common for larger operations. This existing network is a huge advantage for diesel. You can pretty much roll up anywhere and get fuel. The logistics are simple: order fuel, get fuel, use fuel. There are established delivery routes and storage solutions. It's a system that's been refined over decades, and that's hard to beat.

Logistical Challenges for Electric

Electric machinery faces some unique logistical hurdles. Think about it: if a machine runs out of juice in the middle of nowhere, you can't just send a fuel truck. You either need to tow it to a charging station, bring a mobile charging unit, or swap out the battery. All of these options add complexity and cost.

Planning routes and scheduling work becomes more critical with electric machines. You need to factor in charging times and distances to ensure that equipment doesn't run out of power unexpectedly. It's a different way of thinking about operations, and it requires careful planning and coordination.

Here's a quick list of challenges:

1. Limited range compared to diesel.
2. Longer refueling (charging) times.
3. Need for specialized transport for battery swaps.
