Small is Beautiful in the Fast-Changing Solar Power Industry

We perhaps assume that the concept of economies of scale apply when it comes to the generation of "green" energy from solar panels. However, as this excellent video from The Economist explains, the fastest growth in solar panel generating capacity does not come from large solar farms in the desert. Instead, the utility industry is struggling to come to terms with the competitive threat from tens of thousands of small, individual installations which are able to sell their solar power into the energy grid. A great profile of a fast-growing industry and market that is making hay whilst the sun shines!
