The Sun is a renewable energy source, which, if used through so-called photovoltaic panels, allows you to significantly reduce the use of fossil fuels. In Italy, 2000 kWh of solar energy is collected every year for each square meter of surface, which is the equivalent of 1.5 "barrels of oil" per square meter.

Taking into account the map, which represents the solar energy available in the
capitals of southern Italy per square meter, determines:
1) how many barrels of oil could be saved in one year;
2) how many barrels of oil are saved annually with a photovoltaic panel
of 5 square meters
installed in Naples. C1
