Meeting global energy needs represents a key challenge for climate change mitigation. This is because the energy system today is dominated by fossil fuels, which emit a significant amount of CO2 to the atmosphere. In fact, the energy sector is responsible for the majority of anthropogenic emissions, contributing more than 75 per cent of global greenhouse gas emissions.[1] In order to avoid dangerous climate change it is crucial that we transition our global energy system away from fossil fuels and towards low-carbon, sustainable energy.
