Research from LUT University and 14 additional leading international universities suggest that the new system would be based largely on solar and wind energy, energy storage, sector coupling, and direct and indirect electrification of almost all energy demand. An energy system that is 100% based on renewables has emerged to become scientific mainstream.
The problem is that renewables cant produce baseline energy the way coal or nuclear can. Instead the energy output of renewables varies wildly between sunny, windy summer days and dark, calm winter days (as two extremes). Electricity storage is way too expensive to alleviate that. And if we stop using oil and gas, all industry would collapse completely.
