This map shows worldwide heating degree days. Heating degree day (HDD) is a measurement designed to reflect the demand for energy needed to heat a home or business to a human comfort level of 18 °C (65 °F).
Higher Heating Degree Day totals suggest greater heating needs (i.e., a colder national climate).
Note:
- Degree Days = per capita/national average.
- Weighted by Population = national total; It is simply the degree day average for a particular country multiplied by its population.
For more information about the concept of degree days, data source(s), and methodologies used see Data Note: Heating and Cooling Degree Days (PDF).
