With the continued advancements in the development of renewable energy technologies and their ever-increasing cost competitiveness, there is more and more money at stake for countries and companies alike. A number of countries have recently found themselves at odds with one another over the international impact of certain domestic financial support policies for promoting renewables. The United States, China, Japan, Canada, and the European Union, discussed here, along with many others, currently find themselves on varying sides of major international trade disputes on this topic. High-end manufacturing of renewable energy technology components, and the money and jobs this brings with it, is becoming an increasingly important component for policymakers and an increasingly contentious issue at the international level.

The dispute between the United States and China over solar photovoltaic (PV) manufacturing is probably today’s most high-profile renewable energy trade dispute. The Chinese share of global solar PV manufacturing has grown at an incredibly fast pace since the country entered the market, as Chinese manufacturers have rapidly expanded from a 15 percent market share in 2006 to provide nearly half of the world’s total solar PV manufacturing output today. As of 2008 China produced 2,500 megawatts (MW) of solar cells, up from just 4 MW a decade earlier, as reported in the Worldwatch-REEEP report Renewable Energy and Energy Efficiency in China. With an existing installed capacity of 900 MW at the end of 2010, much of this production is being slated for export.
