The first tide generated electricity project was established at Vizhinjam fishing harbour is the site of a unique demonstrations plant that converts sea wave energy to elecricity and is given to the local grid. This plant is based on the oscillating water column (OWC) principle. A caisson was constructed in December 1990 at Vizhinjam and two generations of power modules have been tested as of today. The plant was first commissioned in October 1991. The physical processes in the energy conversion are understood to a much greater extent, leading to a threefold increase in absolute power from the plant. At present, more than 80% cost of the wave energy plant is due to civil construction (concrete caissons). Considerable cost savings can be obtained using the concept of multi-functional breakwaters wherein a power module forms an incremental addition to a caisson breakwater. It is proposed to demonstrate the utility of this concept with the design and construction of a breakwater with a number of power modules.

China, the world’s top greenhouse gas polluter, has passed a milestone in the number of UN-backed clean energy projects, with the world body approving more than 500 such schemes so far. China has the highest number of such projects, which yield tradeable carbon credits for investors in wind farms, solar power, small hydro, biomass or cleaning up planet-warming industrial gases. The scheme, called the clean development mechanism (CDM), is part of the Kyoto Protocol climate pact and aims to help developing countries shift to low-carbon economies and also help rich nations offset their emissions by buying the carbon credits. Each offset, called a certified emission reduction (CER), represents a tonne of greenhouse gas pollution saved from being emitted. s of late Monday, China now has 501 such projects registered, followed by India at 411 and Brazil with 156.(as of April 2009) Globally, the United Nations has approved 1,539.Many of China’s registered projects are in hydro and wind power, with others designed to capture methane from coal mines, landfills and agricultural waste. Hundreds more Chinese projects are in the pipeline awaiting formal approval by the United Nations. To date, approved Chinese CDM projects have
been issued with 119,400,810 CERs, representing more than 40% of the total issued to date globally by the United Nations, but still a fraction of China’s overall greenhouse gas emissions.
