The amount of insolation received varies from latitude to latitude. The Regions within the equator and 40° N and S latitudes are energy surplus regions because they receive abundant sunlight and hence more heat will be gained than lost.The Regions beyond 40° N and S latitudes are energy deficit regions because they lose more heat than that gained from sunlight.
