Unearthing Clean Energy: A Case Study of Advanced Biofuels in South Africa(PPT)

摘要

1.The scale of the algal and cellulosic resources are significant in terms of current global energy consumption. 2. Fuller exploitation of these resources has major implications for energy, climate and food security. 3. Conventional biofuels will have significant impacts on the global bio‐physical cycles (water, nitrogen, phosphorous, potassium); and social factors. 4. Some positive outcomes can occur by default (without substantive policy intervention e.g. energy security). Others will require enhanced policies and regulation. 5. Cellulosic biofuel technologies will enable more biomass resource to be accessed; many benefits but also # of threats.
