China has invested $30 billion dollars in renewable energy.

China’s economy grew 7.9% in the second quarter of 2009.

Analysts said the rebound in China would offer a boost of confidence for the global economy as it struggles out of the worst economic crisis since the Great Depression of the 1930s.

Renewable energy investments have been launched by the U.S. government this year, as well as by governments in Europe and across Asia.

But China’s stimulus is by far the most sweeping, with massive investment in renewable energy, including wind, hydropower and solar development.

Asian stimulus packages could lead to new waves of demand for renewable projects in China. As a result, global demand across the supply chain could shift from Europe and the U.S. to Asia.

“Upcoming solar-power installations have the potential to surpass the original 2020 target of 1.8 GW by up to 10 times, reaching between 10 GW and 20 GW over the next 10 years,” said said Asia Pacific energy and power systems program manager Irina Sidneva.
