"Are current energy profiles dominated by fossils or renewables?"
Energy is a key commodity that enables socioeconomic development. Climate change and, recently, energy security issues have forced the world to ramp up the energy transitions efforts.
There has been much discussion about roadmaps for energy transition. Two aspects, however, must be considered: the new (sustainable) energy model i) should not jeopardize the energy security, and ii) should be affordable. But, one major difference between fossil power and renewables is that solar & wind are intermittent. Also, renewables (REN) are CAPEX-driven (but have low OPEX).
