Expeditionary energy economics

Expeditionary energy economics means figuring out how to make and use energy when we're far away from home. When we go on trips or military missions to other countries, we need to find ways to make or buy the energy we need to run our equipment and buildings.

Imagine you're going on a trip to the beach with your friends. You know that you'll need snacks, drinks, sunscreen, and towels. If you forget to bring any of these things, you might have to buy them at the beach. It's the same with energy when we're away from home - we need to think ahead and figure out what we'll need to make or buy so that we're prepared.

But there are a few extra challenges when it comes to expeditionary energy. First, we might be going to a place where the local electricity grid is not reliable or doesn't exist. That means we might need to make our own electricity using generators, solar panels, or other methods.

Second, we have to think about the cost of energy. Just like how you might decide to bring your own snacks to the beach to save money, we need to figure out how to make energy in a way that's affordable.

Finally, we have to think about the environmental impact of our energy use. We know that burning fossil fuels like oil and gas can produce pollution and contribute to climate change, so we might want to find ways to use renewable energy like wind or solar power instead.

So, expeditionary energy economics is like making a shopping list before we go on a trip, but instead of snacks and sunscreen, we're thinking about how to make or buy the energy we'll need to power our equipment and buildings, while also considering cost and environmental impact.
