Sustainable energy – Swedish fuel use for electricity production (part 4)

In the last blog I said we had to figure out how much of the electricity produced by the cogeneration (CHP) plants came from renewable energy. Fortunately there is a graph for that too. And it says that in 2013 of 20 TWh of electricity produced 15 TWh came from biofuels. The remaining 5 TWh came from a mix of coal, coal gas, blast furnace gas, natural gas, oil and liquid petroleum gas.

Figure: Fuel use in Sweden’s electricity production, excluding nuclear fuel 1983-2013, TWh. Figure from Energiläget 2013, part of figure 14.

Considering that in 2013 Sweden produced 12% more electricity than it consumed, then we should then take the 15TWh of renewable production above and deduct the 12% which went on export. Which gives us about 13 TWh of renewable cogeneration.
This means that we now know how much of the Swedish electricity supply in 2013 was renewable:

  • Hydro power 69 TWh
  • Wind power 9 TWh
  • Cogeneration with biofuel 13 TWh

Other electricity production:

  • Nuclear power 55 TWh
  • Cogeneration with other fossil fuels 4 TWh

That comes to about 150TWh in total. There is probably about 2-5TWh of rounding errors in these calculations, through rounding errors and reading from graphs. I could of course go back to the actual numbers (the publish a spreadsheet), but for the purpose of this exercise I think that is overkill.

For the next blog I will have a look at putting together an overview graph of what is renewables in the total energy use today in Sweden and what isn’t.
