One just can't build a new business model and a new technology relying on government subsidies. The scale of commercial introduction is the key difference between governments' involvement in early Internet development in the 1970-80s and the 2000-10 attempts to deploy green energy across the US and Europe. That is, the Internet was developed on the scale of an extended R&D proeject and did not compete with any mature large-scale existing commercial offering. In contrast, green energy had to compete with very mature, highly efficient commercial technologies. Internet was a new Betting Ground while green energy was positioned as a Better Mousetrap, prone to a failure even with huge subsidies (see the 4-Q diagram below).
