As the moves to the low carbon economy continue, many of the ideas that we believed might get there are unwinding. In recent days we have had biofuels exposed as doing more harm than good and, ergo feed in tariffs. We have had windfarms, we will have tidal power and we all know about nuclear power. Some short comings have come as no surprise, biofuels in the tropics being one, others are more complex.
Take as example feed in tariffs. Very few technologies can generate power at the same cost as existing technologies.
