Energy Efficiency

By Dr Gunnar Hovstadius

In our national and global dialogues about energy conservation we often overlook the role that new technologies – combined with systems analysis – can play in reducing energy intensity, as well as the significant role that the combination of government and industry can play.

In December 2010, the Nedbank Ridgeside building in KwaZulu-Natal (KZN) achieved a four-star Green Star rating from the Green Building Council of South Africa (GBCSA), thereby becoming the second office development in South Africa to be fully certified, and the first in KZN.

In February 2010, Philips, together with the energy company City Power, initiated the lighting of the Nelson Mandela Bridge as City Power wanted to create a legacy for the City of Johannesburg. The brief from City Power was that Philips should to provide them with a cost-effective, energy-saving lighting solution.
South Africa is on the verge of exploring and developing its renewable energy sector. While interest and growth of this market holds huge potential for the country, it is also very risky, says Sharon Kedmi, director-general of Israel’s Ministry of Industry, Trade and Labour.
Africa Thermal Insulations (ATI) manufactures, sells, markets and distributes building insulation products throughout southern Africa. The company’s vested interest in green building materials has lead them to become a renowned manufacturer of radiant barrier reflective foil building insulation products.
In February 2011, 25º in Africa reported on the introduction of the Industrial Energy Efficiency (IEE) improvement project, a collaborative initiative between the Department of Trade and Industry (the dti), the Department of Energy, UNIDO, the Swiss Secretariat for Economic Affairs and the UK Department of International Development.
Pointing to the “inherently unsustainable development path we are on”, World Bank Vice-President Inger Anderson called on governments, international aid agencies, and other development partners to join a new global knowledge platform aimed at fostering green growth. Anderson was speaking at the University of Copenhagen on the theme of green growth.

Energy and nanotechnology

With the recent approval of the Integrated Resource Plan of 2010 (IRP2010) by Cabinet in March 2011, South Africa has committed to generating 42% of electricity from renewable energy sources over the next 20 years.
In a report published by Balancing Act, an online publishing and consultancy business covering broadcast, telecoms, Internet and computing in Africa, it was stated that the number of green mobile base stations deployed in Africa remains small, representing a mere 3.1% of the total number of deployments worldwide (9 558).

Is the IRP focusing on energy-efficiency?

South Africa continues along a carbon-intensive energy strategy, ranking us the 14th largest emitter on the planet. Our emissions are about 1/8th of the total emissions of the European Union (EU). Eskom is also the 2nd most carbon-intensive electricity utility on the planet, ranking only behind Huaneng Power in China on emissions.
