With the increase of international trade, global value chains have been created for 
main renewable energy products such as solar modules and wind turbines. The industries 
of renewable energy products have decoupled from installation. In other words, a country 
with large renewable energy installation capacity does not necessarily have a large 
renewable energy industry.
Table 3 shows this decoupling of industry from installation. The share of China in 
the solar PV capacity is 19%, while the aggregated market share of the five Chinese 
module manufacturers is 28%. On the other hand, some countries with high solar PV 
capacity, most of which are European countries, do not have even one of the top 10 solar 
PV manufacturers. In the case of wind energy, the home countries of the top 10

manufacturers are not exactly the top 10 countries in terms of wind power capacity. For 
instance, Denmark has Vestas, which has 12% of market share in wind turbine market, 
but it is not one of the top 10 countries in terms of wind power capacity.
