The utility company evaluates the energy sources based on their land use per reliability factor. In other words, how much land each source uses for every point of reliability ( (land use)/(reliability) ). Using this evaluation, a lower value means the source is more efficient because it uses less land for the amount of reliable energy it provides. Arrange the energy sources from most efficient to least efficient. Place the most efficient resource at the top of the list.
A base-load energy source provides a constant and reliable supply of electricity all day and night. Complementary energy sources work well together by compensating for each other's weaknesses, such as producing power at different times of day or in different weather conditions. Select each renewable energy source's primary role in a broader energy system.
