Researchers from the University of Warwick have produced a startling calculation that any move to replace the UK’s oil burning vehicles with greener hydrogen powered cars and trucks would require the erection of 100,000 new wind turbines or 100 new nuclear power plants. (...) They found that it would require approximately 100,000 new wind turbines. If sited off-shore, this would mean an approximately 10-kilometre-deep strip of wind turbines encircling the entire coastline of the British Isles. If sited on-shore, the area covered by wind turbines would be the size of Wales.
