given a map, describe the spatial variation in access to electricity?

As a general trend Northern regions (North of the Brandt line) have full access to electricity, such as in Western Europe and North America. Outliers to this trend South of the equator include Australia and New Zealand, however, for some neighbouring islands access to electricity falls within 50-60% of the population.Areas with particularly poor access of 0-20% include Sub-Saharan Africa, for example Niger. Moreover, some countries to the West of the map in South America also have populations with limited access, as well as to the East in Asia. An obvious anomaly is Bhutan in South Asia in which 80% of the population has access to electricity.
