Synopsis: This paper suggests the use of windfarms cannot make significant contribution to reducing the emissions and suggests the construction of tidal coffer dams instead. Windfarms for power generation provide intermittent power so they merely displace thermal power stations onto standby mode or to operate at reduced efficiency while the thermal power stations wait for the wind to change. They make no significant reduction to pollution because thermal power stations continue to use their fuel and to produce their emissions while operating in standby mode or with reduced efficiency that can increase their emissions at low output. And this need for continuously operating backup means that windfarms can only provide negligible useful electricity to electricity grid supply systems. But the large scale use of windfarms requires upgrading of an electricity grid, more complex grid management, and operation of additional thermal power stations to protect against power cuts in time of supply failure. These effects increase the cost of electricity supplied by the grid in addition to the capital, maintenance and operating costs of the windfarms themselves. And the windfarms cause significant environmental damage. Tidal coffer dams would not have these problems and could provide continuous and controllable power supply at similar cost to off-shore windfarms.
