Main economic revenue of Algeria is related to export of hydrocarbons such as natural gas and oil (up to 95 % of its export) and the global falling of oil prices effects national economy. Also at the country level more than 90 % of the energy used is based on fossil fuels; deployment of renewable and clean energy technologies is still not widely developed. Algeria should adopt the renewable energy for its further development taking into account the favourable climatic conditions such as abundant sunshine throughout the year. The objective of this research is to apply a Sustainable Solar Urban Planning methodology used for definition of solar potential in urban planning for the city Ibenbadis (Constantine, Algeria). Obtained results allows us to compare the solar potential calculated for three different urban sites - the city Ibenbadis (Constantine, Algeria), Alcabideche (Cascais Municipality, Portugal) and Riga (Latvia).
