Dynamic life cycle assessment (LCA) of renewable energy technologies
First step: static LCA of
renewable energy technologies
Methodology, goal and scope
Data from various literature LCAs
The time reference is 2010
The results are normalized
Results
Greenhouse gas emissions and the consumption of non-renewable energy resources of renewable energy systems are significantly lower compared to those of conventional systems
There are clear advantages under the headings of greenhouse effect and consumption of finite energy resources
It is not possible to reach an objective decision
Second step: dynamic LCAs of
renewable energy systems
Methodology
Dynamic development in individual technologies
Dynamic parameters of the background system
Future orientated power plants
Aluminium
Steel
Further processes
Examples
Steam turbine power plant with timber from short rotation forestry
Central heating with forest timber
Photovoltaics
Expanding the system boundary:
effects on the consumer
Behavioral changes
off-setting certain symbolic types of environmental action against behavior in other areas
Increased expenditure available
