In any decarbonisation scenario, a rapid growth in renewable energy is essential. At the same time, it is highly questionable whether future greenhouse gas emissions can follow a pathway that is consistent to the objectives laid out in Paris, if renewables are supplemented by an unnecessarily high carbon intensive mix of power generation technologies. The Gas4Power scenario in this paper, based on a study commissioned by the Strategy Committee of the International Gas Union, demonstrates an alternative to the continued use of coal as a supplement to the rapid expansion of renewable energy production, in a dynamic decarbonising fashion.
