Renewable energy has become a topic of increasing interest in recent years, as fossil fuel prices have been volatile and the focus on climate change has sharpened. Governments in many jurisdictions have been instituting policies to increase the installation of renewable energy capacity, as the technologies involved are not generally able to compete on price with conventional generation.
The reason this is necessary, as we have pointed out before, is that the inherent fossil-fuel dependence of renewable generation leads to a case of receding horizons. We do not make wind turbines with wind power or solar panels with solar power. As the cost of fossil fuel rises, the production cost of renewable energy infrastructure also rises, so that renewables remain just out of reach.
