Efficiency elide

Debates on UK energy policy focus almost exclusively on energy generation/production and often neglect even to mention energy saving and energy efficiency. It’s always going to be cheaper to save energy and be efficient than it is to generate it - not only does it cut household bills and increase the profitability of businesses by reducing their outgoings, it also cuts pollution rapidly, is a very good job creator, can increase comfort, cut noise levels, and can sometimes be done using materials normally thrown away...So whilst we are so wasteful of energy why consider building large numbers of new power stations of any kind? Why is our primary focus not on creating a lower energy, energy thrifty culture? Basic, already existing technologies can be used but the challenge is to combine these with thrifty attitudes and behaviours.

The energy generation debate at present often zooms in on nuclear and wind. Nuclear power is low carbon emission in operation but we’ve had it since the 1950s and it has done nothing to stop climate change. The UK currently has nuclear 16 reactors in operation at 9 different sites - and it’s had more in the past. We've come to rely on fossil fuels and population has increased as has our level and intensity of consumption but expanding nuclear power for decades - and expanding power generation by all methods - has been part of unsustainable plans for industrial and economic expansion. This attitude still prevails. Until we change from unsustainable economic expansion to properly and fully applying sustainable development - including an energy policy with energy saving and efficiency as its primary focus - then we won’t tackle economic, social and environmental problems such as climate change.
The scale at which we waste energy is vast, so the scope for energy saving is huge. For example the Energy Saving Trust said that UK households waste £1.3 billion by just leaving TVs and other electronic devices switched on... http://www.telegraph.co.uk/finance/personalfinance/consumertips/household-bills/9355870/Energy-Saving-Trust-households-waste-1.3bn-for-leaving-gadget-switched-on.html# . In hard economic times and with energy prices rising you'd think people would be more careful with their consumption but apparently they aren't, so we’ve made little progress towards a energy thrifty culture. Research in 2006 found the UK was top of the European energy waster league. http://news.bbc.co.uk/1/hi/uk/6075794.stm

Part of the problems is the fact that my local paper can’t even write a balanced and correct piece about nuclear power, let alone cover energy issues in the round as it should do. People are often ill-informed as a result.  Here's my case against nuclear power: http://tinyurl.com/c75rvbg.Here's  a  post arguing for energy efficiency, combined heat and power and decentralised energy: http://tinyurl.com/cxagb4o.  Some thoughts on local renewable energy developments here: http://tinyurl.com/bm5m764.
