Market TrendsMarket DriversMarket RestraintSegmentationRegional AnalysisKey Industry PlayersKey Industry DevelopmentsReport CoverageRequest a Free sampleto learn more about this report. Increasing Energy Demand Fuel Market Growth The growing population and growing rate of urbanization are likely to increase the demand for energy across the globe. According to the United Nations report in 2018, about 55% of the world’s population lives in urban areas, which is projected to increase to 68% by 2050. The extensive population shifting to cities is increasing the demand for electricity. Moreover, enormous construction activities to build commercial spaces, business parks, and housing societies are set to spike power demand. Hence, the space constraint in urban localities and growing energy demand is projected to further propel the gas insulated switchgear market growth during the forecast period.Get price
