Electricity consumption in Portugal

Today I received a message from EDP, the only portuguese electricity company.
It's about electricity labeling, that is, knowing where the electricity offered by EDP comes from.
In 2008, electricity that was generated in Portugal came from conventional thermoelectric stations fed by coal, natural gass, fuel-oil and biomass, and hydroelectric plants and wind. The rest of it was imported from Spain.
The following figure (in portuguese) shows the electricity offered by EDP per technology.


Nuclear power is responsible for 5.3%, all of it imported from Spain. There are no nuclear power plants in Portugal and yet we consume electricity from that source.

Fossil fuel still represents the higher share in electricity production with 61.1%. Renewables represent 33.7%.

Monthly share of electricity consumption per technology (2008 data)

The figure shows the irregularity of hydroelectricity production. Fuel-oil reaches almost 10 % in December, but has lower shares throughout the year.

Air emissions in 2008

Air emissions are a consequence of that electricity mix.
