Coordinating hydropower and wind power satisfies hourly operation requirement. Swedish government's target is to have 100% renewable electricity production by 2040. Currently, hydropower contributes the majority of renewable electricity generation of the country. The wind power capacity has increased significantly in the past decade.
In the recent decade, wind power capacity in Sweden has increased significantly. The electricity generation from wind power in 2009 was 2.5 TWh, which was 1.87% of the total electricity generation of the year. In 2019, it increased to 19.9 TWh, which is 12.1% of the total electricity generation.
The target wind power capacity 25,000 MW is around triple of current existing wind power capacity in Sweden. In other words, if the wind power capacity can be tripled from 2019, it is possible to reach a 100% renewable electricity generation system in Sweden.
Sweden has a wave power station outside Lysekil run by Uppsala University. The wave energy research group at Uppsala University study and develop all different aspects of wave energy, ranging from power systems and generators, to hydrodynamical modelling, and environmental impact of wave energy parks.

Because it is estimated that in 5G, the base station's density is expected to exceed 40–50 BSs/ Km 2 . The energy consumption of the 5G network is driving attention and many world-leading network operators have launched alerts about the increased power consumption of the 5G mobile infrastructure .
However, the construction and operation of 5 G base stations face significant energy consumption challenges. Under full-load conditions, the power consumption of 5 G base stations is approximately 3–4 times that of 4 G base stations, which has a notable impact on energy consumption and environmental concerns (Zhang et al., 2020, Feng et al., 2012).
This restricts the potential use of the power models, as their validity and accuracy remain unclear. Future work includes the further development of the power consumption models to form a unified evaluation framework that enables the quantification and optimization of energy consumption and energy efficiency of 5G networks.
