Issue overview

Steep electricity price increases are making

technologies like rooftop photovoltaics and

solar water heaters financially attractive to

high end users

Sustainable Energy: Sustainable Tourism

• Sustainable energy:

– Energy efficiency and renewables

• Being hospitable

• Tourism in the broader context

• The diversity of the Eastern Cape

• Prioritising the options – cost and benefits (EERE)

• Getting started

• Going all the way

– Benchmarks and indices

• Finding the right partners
