Rising oil prices make tidal power a better prospect

In your report on the Severn Barrage a crucial justification for the project is not mentioned.

The key feature of so-called renewable sources of energy, such as tidal, hydro-power, pumped storage and wind, is that they are not fossil fuel emission free or even fossil efficient.

The fossil fuel emission is inherent in the initial construction stage while the fossil free operation stage comes later.

So with the scarcity price of finite fossil fuel set to rise the case for proceeding urgently seems clear. The economic and strategic case grows stronger every day. It could even be said to be a matter of national economic emergency.
