Brief letters: Solar, wind and water | French connection | Gianni Infantino | ‘Good athlete’ Trump | USA 1 Belgium 4

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.

• Now that Gianni Infantino has demonstrated that there is a role for politics in sport (Trump confirms he asked Infantino for review of Folarin Balogun red card, 6 July), can we expect regimes that fail to observe international law to be excluded from participation in international events?

• 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.
