The world's largest electricity generating tidal barrage may be built across Britain's Severn estuary by the end of the century.

在本世纪末世界上最大的发电拦潮大坝可能在横贯英国的塞文河口建立起来。

A few tidal projects, such as the 42-year-old barrage at rance in France, operate like traditional hydro schemes, in which tidal water simply rushes through turbines.

一些潮汐能设施的运作就像传统的水力发电计划一样——潮水直接在涡轮机中流过。法国兰斯的一个有42年历史的堰坝，就属于这一类。

The newspaper said plans to build a 10-mile long tidal barrage, that could generate up to 5% of Britain's electricity, are likely to be shelved under a government cost-cutting drive.

The massive Severn estuary tidal barrage scheme had been rejected by the coalition government because of its environmental impact, but ministers have indicated they are open to review the idea.

However, the SDC report concluded that it did not "consider that a large-scale tidal lagoon development in the Severn estuary would offer any environmental or economic advantage over a tidal barrage".
