The Chinese government has helped turn the country into an alternative energy powerhouse using a slew of policies that support domestic renewable fuel industries, according to a study released Monday.

A sweeping mix of preferential financing, rebates, tax incentives and subsidies for Chinese-owned and -controlled clean-tech companies between 2002 and 2009 was implemented as the country faced rising energy consumption, according to the report from the National Foreign Trade Council.

Policies include the 2005 measure that required wind farms in China to be built using at least 70% locally produced materials, which pushed several international companies to establish manufacturing facilities in the country. Chinese utilities must buy all renewable energy generated in the country and then offer the power to consumers at a discount, according to a 2006 law.

A $586-billion stimulus package from 2008 allocated significant funds to renewable energy projects, and a 2009 program offered 50% investment subsidies for solar power systems connected to the national grid.
