In answer to Adrian Toole’s letter, (February 5th 2015.) about my comments not standing up to scientific scrutiny. The facts concerning the super containers ships and their Sulphur Oxide emission. Can be seen in the UN’s International Maritime Organization (IMO) report of 2007. This is a tiny part of it. The world’s 90,000 vessels burn approximately 370 million tons of furnace fuel oil per year emitting 20 million tons of Sulphur Oxides. That equates to 260 times more Sulphur Oxides being emitted by ships than the world’s entire car fleet. On wind turbines. The report for the Adam Smith Institute by Dr. Capell Aris who analyzed data on the wind speed and direction collected from a total of 22 sites across the UK, with 6.5m individual recordings. Found for the sake of brevity that UK wind farms top 80 per cent of their potential output for less than a week every year. Whilst most of us do not want millions of litres of toxic chemicals used in fracking leaking into the water table, and nuclear waste as a lethal shelf live of 250,000 years We are left for energy security with one source coal, which we in the UK have around 700 years give or take the odd leap year. Whilst the greens discredit this form of energy. If we had spent just 10% on clean coal as we have on inefficient wind turbines. We would have a far more secure energy source and cleaner. Why not ask Germany there going back to it. Of course what about carbon capture. An unsolvable problem perhaps, or far too expensive maybe. Not really nature had the problem cracked around 370 million years ago. They are called trees.Adrian Toole says:October 1, 2015 at 11:38 amI’m now told that the major contribution to global warming is in fact the raising of farm animals! So we should all become vegans.David the issues you raise, seem to have no solutions, at least none that we in Exmouth can influence. What can we do about international shipping?why has our government not invested in this supposedly ‘clean coal’ what is that exactly? Instead they have mortgaged every single one of us to persuade the Chinese and French to build a new generation of nuclear power stations and nobody can accuse the green movement of inaction on that front.We can however hope to influence local development to be sustainable. A report for Greenpeace concluded that we could provide 85% of electicity from renewables by 2030 including perhaps 77GW of windpower, that seems like a significant contribution from a benign technology.
