Energy spending is judged here by its contribution to a secure domestic supply. Tidal stations are criticised as expensive for the power available before adequate storage is settled. That objection makes storage part of the proposed test for whether generation spending is worthwhile. No named tidal scheme or quantified cost comparison is supplied, so the criticism remains a general policy judgment.
