US targets China’s wind subsidy

Issue Date: Jan 31, 2011
AFTER scuttling talks on transfer of technology in the recently concluded climate change conference in Cancun, the US now wants China to stop its clean energy programme. The US, on December 22, filed a complaint with the World Trade Organization (WTO) that China is unfairly helping its domestic wind power equipment manufacturing industry with soft loans, cheap land and subsidies, thereby giving it a competitive edge.

The country’s new energy minister, Champika Ranawaka, wants a nuclear power plant by 2025. That’s a sure sign of change: Ranawaka started his career as an activist against coal power. He was the environment minister in the last government.

Till September 6, Gujarat’s Secretariat campus in Gandhinagar boasted the largest installation of solar panels in India. Now it has another distinction— the campus has become home to the country’s first smart grid. A smart grid transmits and distributes electricity using information and communication technology. It helps control electricity use by making consumption patterns more visible.

SOLAR cells get damaged and lose efficiency from constant exposure to sunlight. Then how is it that plants show little wear and tear though they too capture the Sun’s energy during photosynthesis?
