An energy vision: The transformation towards sustainability-interconnected challenges and solutions

The energy system is currently facing a number of challenges, most notably high consumption levels, lack of energy access, environmental concerns like climate change and air pollution, energy security concerns and the need for a long-term focus. Addressing these critical issues simultaneously will require a fundamental transformation of the global energy system. Recent assessments show that such transformational pathways are achievable in technological and economic terms, but constitute formidable governance challenges across scales. In this paper, we discuss a long-term vision for the energy system and elements of the transition towards this vision. This transformation would need to be based on several key components, including taking an integrated approach as basis, the focus on high levels of energy efficiency and the scale up of investments, also in RD&D.
