The report attempts to answer key questions related to India’s energy trajectory such as how much energy does India need to achieve the high value of Human Development Index (HDI); what are pathways to achieve this; what are the energy mix projections for this until 2070 (our declared net-zero target year); what would be the cost of electricity to the end user; what would be the carbon emissions until 2070; what would be the investments required for energy transitions towards net-zero at 2070; estimation of other challenges and opportunities (RE integration, the requirement of critical minerals, Carbon Capture Utilisation and Storage (CCUS), natural gas, ethanol, hydrogen) in energy transitions towards achieving net-zero in 2070.
