5.2.7 Total Savings by Energy Housekeeping Measures
The saved energy, costs and carbon dioxide emissions for the energy housekeeping measures
have been summarised in table 4. As can be seen in the table, approximately 750 MWh/year
of electricity and more than 500 000 SEK/year can be saved by these measures. As a
comparison, the emissions saved by the energy housekeeping measures equals 322 modern
cars in Sweden each driving 10 000 km/year. [20]
