Solar energy not war
If you know that a sector has arrived when it makes for trade wars between countries, then solar energy clearly has. Last year, the US imposed anti-dumping duties on Chinese imports of solar panels; now the EU has proposed the same. The Chinese have in turn threatened that they will take action against European exports of poly-silicon, the material used for manufacturing solar panels. In February this year, the US filed a case against India at the World Trade Organization (WTO) for “favouring sourcing of panels from domestic manufacturers”.
