Stephen's views on the Severn Barrage

I have recently put forward a motion to parliament urging ministers to look again at the prospect of a Severn Barrage.

The barrage would generate about 6% of the UK's electricity needs from the ebb and flow of the tides. It was last looked at almost 20 years ago, but rejected due to environmental concerns. However, given new worries over global warming and advances in technology I believe that the scheme should be looked at anew and included in the government's current energy review.

The Severn Barrage would be a green and clean way of generating 2000 Mega Watts of electricity - equivalent to 3 nuclear power stations or 10 million tonnes of coal. This would contribute enormously to meeting our targets on carbon dioxide emissions and therefore should be looked at carefully. There are possible issues surrounding cost and the effect on bird life, however these need to be considered in light of the global threats we now face.

Unlike other renewable energy like solar and wind power, tidal power is completely predictable and therefore a very reliable energy source. Even when the tide does not coincide with peak demand, because we would know when to expect it the energy could be stored in some form elsewhere.

I recall the huge local controversy when the new nuclear power station was opened at Hinkley Point. I'm fearful that Tony Blair will push for a new generation of nuclear stations, rather than investing in renewables.

This motion backs up Lib Dem lead Bristol City Council, who made a similar call for a rethink on the issue at a recent meeting and then wrote to the Government with the meetings decision to back another look at a Barrage proposal. The Welsh Assembly are also reported to be considering the idea and have had recent press coverage on the subject.
