Remember water power in the renewables mix | Brief letters

Your article (Why can’t Britain turn its green revolution into cheap energy? A visual analysis, 4 July) was an informative overview, yet I saw no mention of water power. If we are serious about building a resilient, low-carbon energy system, wave power, tidal power and hydroelectricity deserve to be part of the conversation alongside wind and solar.

Re your article (Mobile internet coverage in UK worse than any EU or G7 country, Which? says, 6 July), glancing at my mobile in the Square and Compass pub in Worth Matravers, a stone’s throw from Dorset cliffs, service is provided by Bouygues Telecom (France). Cherbourg is 58 nautical miles away.

Given Fifa’s amenability to technical inquiries from “good athlete” Trump, surely a quick recount to review the possibility of four overlooked US goals in the Belgium game might be in order?

Donald Trump certainly knows how to motivate a team; unfortunately for him, it was the wrong one.
