In times of sharply increasing Swedish electricity prices, it can be interesting to study how the use of energy and natural resources has changed over time.

During the period 1970-2018, Sweden's total energy use increased by 25 percent. During the same period, the country's population increased by two million, while the real economy increased by 176 percent.

Sweden's energy mix has changed over time. Crude oil and petroleum products' share of the energy supply decreased from 76 to 19 percent. An important reason for this is the rise of nuclear power. We also see an increase in the proportion of biofuels from 10 to 26 percent.

If you look at households, energy use has decreased by 23 percent from 11 to 8.5 megawatt-hours per year. Continuous efficiency improvements in the economy are behind this change. Today's lighting consumes a fifth of energy compared to the 90s. A refrigerator consumed 1700 kWh 20 years ago, a modern refrigerator uses only 450 kWh.

Water use has also improved considerably. Since 2002, energy use for heating and hot water per square meter in houses and other premises has decreased by 25 percent. Heat pumps, improved insulation, and modern windows are some of the factors behind this change.

If we look at the use of electricity, we also see a significant improvement in efficiency over time.

As we see in Figure 4 above, electricity use has been largely unchanged since 1990. Parallel to this, GDP has increased by 85 percent.

In summary, it seems possible to get more for less, also regarding electricity use and energy. Sweden phased out fossil fuels for a long time, oil products were replaced by nuclear power, mainly during the 70s. In the next stage, the Swedish economy has gone through continuous streamlining. Electricity use has been largely unchanged for 30 years, while GDP has risen by 85 percent.

⚡ New drilling technology from the oil industry provides fossil-free electricity around the clock

The cost of drilling geothermal wells has decreased by 80%. Cold water is pumped down four kilometers into the ground through a hockey stick-shaped borehole and heated to steam by the heat down there. The steam returns through a parallel borehole and drives turbines that produce electricity.
