Some environmental problems can be resolved by relatively straightforward technical changes and adjustments – by what are sometimes called technical fixes. This chapter looks at some examples of attempts to make ‘green products’ available to domestic consumers, with energy saving being one of the aims. It also looks at technical fixes in the energy generation field and in transport. But as this chapter argues, while some technical fixes may be helpful as a way of reducing energy use and pollution, on its own the technical fix approach may not be sufficient to ensure environmental sustainability. More radical approaches may be needed, especially in relation to energy generation.
