The largest one of tidal power stations in China, Jiangxia Experimental Tidal Power Station with the installed capacity of 3200kW was built up in winter, 1985.
The tidal power at the southeastern side of Baisha Island has a tiny increase.
One trouble with tidal power is the difficulty of servicing underwater installations.
The strengthening of the tidal power caused by the significant topographic change is responsible for the rise of the low water levels in the tidal reach.
For example, San Francisco considered installing giant turbines under the Golden Gate Bridge and harnessing tidal power to generate electricity.
While this may seem an obvious way to go after tidal power, there are some inherent problems.
And other products of the DEC include gas turbine, photovoltaic power generation units, tidal power generation units, seawater desalination equipment and pressure vessels etc.
His energy minister predicts that by 2015 Gujarat will generate 10,000 megawatts from solar, wind and tidal power, enough to power three Mumbais.
Then there are more fringe alternatives like tidal power, geothermal energy and even nuclear fusion-any of which could take off with enough luck and money.
Overall, the program does not result in tidal power variation in waters to the north of Toumen Island unfavourable to the port development.
Measures must be taken to protect the aquatic resources when building harbours and oil terminals, as well as water conservancy facilities and tidal power stations in estuaries.
In the construction of tidal power plants, the floating caisson method may reduce the cost shorten the construction period, and improve construction conditions.
A solar energy system that doesn't require sunlight is almost as bizarre as a tidal power system that doesn't use water - however that's exactly what researchers at MIT have cooked up.
And, like all Marine energy, tidal power may be easiest to produce in places where it is least needed-far away from centres of population, where connections to the national grid would be expensive.
Luke Blunden, a researcher at the Sustainable Energy research Group at the UK's University of Southampton, is optimistic about tidal power's prospects.
