CONFERENCES

The Centre for Renewable and Sustainable Energy Studies (CRSES) annually hosts a student symposium to provide Masters and PhD students in Renewable Energy with the opportunity to present their research on a public forum. The first symposium was held on 11 and 12 November 2010 at the Sustainability Institute outside Stellenbosch. This year's symposium was held at the same venue on 17 and 18 November 2011. The papers presented by the students are listed below.
