What factor mostly contributes to higher electricity costs in some U.S. regions?

The geographical location of a region significantly influences its electricity costs due to several interrelated factors. Certain areas have a higher propensity for energy generation from expensive sources, such as oil or natural gas, which may be necessary when local renewable resources are scarce. Additionally, regions that are far from energy supply sources or transmission lines may incur higher transportation costs, further driving up the price of electricity.

Moreover, geographical features, such as mountains or lakes, can impact the feasibility and efficiency of energy infrastructure, influencing the overall cost structure. Regions prone to extreme weather may require additional infrastructure to ensure stable power supplies, contributing to increased costs. Therefore, the characteristics of the geographical location directly affect the types of energy generation available, the investment needed for energy delivery, and the operational expenses incurred by utility companies, ultimately leading to varying electricity prices across different U.S. regions.
