Value Chain Assessment of Technology for Climate Change Mitigation and Integrated Contribution Approach (Vol.2):
PV Power Systems, CO2 Emissions and Energy Consumption
Summary
In the LCS proposal “Value Chain Assessment of Technology for Climate Change Mitigation and Integrated Contribution Approach: PV Power Systems” which was issued in March 2017, we reported the results of value chain evaluation of manufacturing and utilization of solar power systems.
In particular, based on the research results of LCS's Quantitative Technology Scenario Research, the economic effects by regions where costs occur (in Japan, other developed countries and developing countries) were estimated, tracing back to main raw materials. The point lacking in the previous proposal was the evaluation of CO2 emissions and energy consumption from production through to installation. This proposal added indicators for CO2 emissions and energy consumption. While the economic impact on Japan was 62%, CO2 emissions and energy consumption were as low as 40% each. In Japan, it is more the manufacturing equipment, inverters and other high value-added equipment technologies that are manufactured, than the basic raw materials. Further consideration will be important in response to policy discussions, such as future development to other technologies and application to other indicators.
