I work in green technology. What we should be doing at the moment, in my opinion, is instead of producing new technology to add to what we already have, we should be making what we have a lot more efficient. The UK is very wasteful in energy terms, particularly when it comes to large scale energy production and distribution. One particular example is cooling towers; cooling towers are used to cool steam created during the process of creating electricity. We all have boilers in our homes which produce hot water using gas...why not just use the hot water to skip the boilers and just get the hot water that was being produced anyway!!! How wasteful.
