7. 2 Policies and Scenarios for Renewables, Societal and Global Challenges
Summary / Abstract:
In many countries, energy transition policy aims to increase the share of variable renewable energy sources like solar and wind in the power sector. A large-scale integration of intermittent renewable energies into the existing energy system will change optimal conditions of yearly full load hours of dispatch-able capacities and power production mix. The challenge is to find a proper balance between renewable production at competitive costs and the remaining system. Therefore, policymakers need to work on trajectory of energy transitions to limit carbon emissions based on a systemic approach to consider diverse aspects of renewable integration. France decided to reduce 70% of greenhouse gas emissions from fossil fuel consumption and to reduce the share of nuclear energy in the national power production to 50% by 2035 from the current 75% as part of its energy transition strategy. This leads to strong growth in renewable energies to build a future French electricity system, the massive deployment of electric vehicles and a rapid increase in the self-consumption of electricity. This will lead to new economic features of electricity system.
