COUNTERING Bob Rush's enthusiasm for scrapping renewable targets (letters, Times, January 29), I'd like to ask how he proposes reducing the threat of manmade climate change, now acknowledged as one of the biggest we are facing, and how we're using up our energy resources at the expense of future generations? The recent reduction in gas and oil prices undermines global efforts to reduce dependence on fossil fuels. Has Mr Rush considered the vulnerable countries in Latin America, Africa and Asia where the ecosystems, communities and authorities are even less able to cope with the impacts of extraction and use of fossil fuels? Thanks to advancing technology, wind power is more efficient and affordable than it has ever been. If you go back ten years ago, the turbine was at about 25% capacity factor. Today, it's over 50% and improving, for example with the development of floating wind turbines which use floating structures instead of requiring wind towers be set into a foundation under water. His 'good old coal and gas', contributing a 'lion's share of 71%' is unsustainable, not only because supplies will eventually run out, but our world will face extinction due to pollution. Furthermore, Fukushima after Chernobyl has shown the inherent dangers of nuclear power, not mentioning the insoluble scrapping problems!  There is no one-size-fits-all perfect solution to creating energy without causing damage to the environment. Currently, wind energy has many benefits and these are set to increase with technological advancement. It may not be the answer to the world's electrical needs, but combined with other renewable energy resources, it can help us cut our dependence on coal and oil. Ishbel Askew Sampford Courtenay
