Many energy systems have only a small environmental impact due to their conversion processes. For example, electricity generation. The CO2 example is an example.2Commonly, emissions from fossil fuel burning are scrutinized. It is important to consider the environmental effects of decommissioning oil wells and discovering and extracting fossil fuels. It is possible to evaluate the cumulative environmental impact of both renewable and non-renewable energy systems by examining each stage of their life cycle.
