Answer:
The main problems with bringing electricity to the Arctic are the climate and the condition of the soil.
Step-by-step explanation:
The Arctic is one of the hardest areas in the world when it comes to bringing electricity to it. While the economic factor plays a role, it is still not the crucial one, as there can be enough investments without any particular problem to set up the infrastructure. The problems are in maintaining, preserving, and stabilizing the electrical infrastructure.
The problems come mainly because of the climate and the condition of the soil. The climate is very cold which affects the amount of electricity that is delivered, but the bigger problem is the constant powerful winds that are breaking up the installations. For most of the year, the soil is frozen, which is not a great starting point, but an even bigger problem is that it defrosts in the summer, the soil is oversaturated with water and not stable at all, so the electricity polls fall or lean.
