Ghana is gunning for nuclear energy to account for 30% of its energy mix by 2070, with renewable energy set to account for about 20%. “We see three key energy sources play a leading role in the supply of energy for the people of this country. First, we want to expand renewable energy to about 20 000 MW by 2070. That will mean that renewable energy will account for 20% of the country’s energy mix,” Energy Ministry power directorate deputy director Seth Mahu told journalists in Accra last week.
