Energy efficiency is an important component to reaching net-zero greenhouse-gas emissions, lifting people out of energy poverty and enabling development, but requires public and private investment to secure these benefits, as well as growing development and use of renewable energy sources, speakers said during the African Energy Indaba ‘Role of Energy Efficiency in Achieving Net Zero’ panel discussion on March 2. Renewable energy engineering, procurement and construction company Turnkey Solar Solutions CEO Maurits Perold said various case studies, and the company’s own experiences in implementing projects, show that phased energy efficiency initiatives contribute to offsetting about 7% to 10% of total energy costs.
