Remember water power in the renewables mix | Renewable energy

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.

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