The electricity consumed in our homes through the Grid is called "gray", because it is the mixture of electricity produced by different sources (e.g. lignite, natural gas, hydro power, wind, etc.)
By combining the GreenPass with the electricity program, we are essentially buying "sustainable features" for the "gray" electricity we consume. In this way we reduce the energy footprint of our household, i.e. carbon dioxide (CO2) emissions and at the same time we support the implementation of investments in Renewable Energy Sources in Greece.
