Until shale gas came along, nuclear power was the form of energy most associated with rightwing politics. This is odd when you consider just how dependent the nuclear industry is on the state for its continued existence.
Technologically and economically, nuclear is too risky for the private sector to go it alone. Though some private businesses may be involved, the industry is and always will be a project of the state (the French state in particular).
Solar power is at the opposite end of the spectrum. Indeed, it is the only significant technology that enables ordinary consumers to generate their own electricity. For that reason it shouldn’t just appeal to environmentalists, but also to those of a libertarian mindset.
In the Guardian, Giles Parkinson reports from America, where parts of the Tea Party movement are starting to see the attraction:
But isn’t solar power ridiculously expensive – costing much more than wind or nuclear, let alone gas-fired generation?
The thing to remember with energy cost comparisons is that the situation is never static, it moves with developments in the relevant technologies. In the case of solar, the pace of change is dramatic:
Furthermore, because photovoltaic panels can be installed at the point of use, solar doesn’t have to compete with the wholesale price of electricity. Rather it is the much higher retail price that is the relevant benchmark. In cool and cloudy Britain, we're still a long way from this so-called 'grid parity'. But in sunnier parts of the world – like the southern United States – solar is closer to being competitive. Needless to say, the local utility companies are less than thrilled at the prospect:
Solar, of course, has an Achilles’ heel: it only produces power when the sun is shining. Further improvements in battery technology will be required before consumers can independently compensate for the intermittent supply provided by their panels. For this reason, the utility companies are still in a position to kill off the competition.
Whether they are allowed to do so is down to the politicians:
