South Africa’s pursuit of energy security and the correct energy mix must be hinged on science-based policy, and government must take on a leading role, Electricity and Energy Minister Dr  Kgosientsho Ramokgopa said in a keynote address, on February 24, at the first day of the South African National Energy Development Institute’s (Sanedi)’s third yearly conference, being held this week in Ekurhuleni. He pointed out that with energy and the energy complex being the “defining moment of our time”, stakeholders like Sanedi would be pivotal in helping resolve the questions surrounding this and guiding the country’s policies.
