We, as inhabitants of this planet, are living beyond our means. According to UNEP (United Nations Environment Programme), the world's population has reached a stage where the amount of resources needed to sustain it exceeds what is available.
The WWF (World Wildlife Fund) Living Planet Report 2012 tells us that we are using 50% more resources than the earth can provide.
To assess whether or not there is hope when discussing the 'energy and sustainability' debate, the author poses the follows questions:
- What is the current reality regarding energy and sustainability?
- What needs to happen to secure a sustainable future?
- What is the likelihood of this actually happening?
- How does this affect me and the choices I make today?
- The predictions for world energy consumption show a relentless increase despite conservation and fuel switch efforts.
- In South Africa, the IRP (Integrated Resource Plan) of November 2011, envisages a total electricity supply in 2030 of 89,5 GW.
- While the IRP shows a serious move to renewable energy, it forecasts that coal will still be 46% of that total.
