Abstract
During the past decade governments across Europe have set in place a series of programmes to expand investment on grid-connected solar power technology, most especially Photovoltaics (PV). Recently most of these programmes have been rolled back, in face of rapidly declining costs. Using a simple model this article shows that basic PV electricity costs are presently below 0.10 €/kWh in large swaths of the continent, entering levels where previously only nuclear and fossil fired electricity where found. Due to the scalable nature of PV, many households in Europe are now able to produce their own electricity at a cost considerably lower that the rates demanded by grid utilities. If governments proceed with the complete roll back of fixed electricity rates to PV suppliers the most likely result is a shift to off-the-grid systems. Long term this trend presents serious challenges to utilities and traditional electricity suppliers, putting at stake the traditional electricity market framework.
Highlights
The Renewable Energy Sources Act (2000) passed in Germany is regarded today as the turning point for solar power technologies in Europe
Known as feed-in tariffs (FIT), these mechanisms triggered watershed development of solar technologies, with PV emerging as a clear winner
It is possible that innovation dynamics alike those seen for other technologies are in place for PV, such as Moore’s Law for micro-processors (Schaller, 1997)
Summary
The Renewable Energy Sources Act (2000) passed in Germany is regarded today as the turning point for solar power technologies in Europe. It introduced mechanisms on which many other member states inspired their own legislation: the mandatory purchase of renewable electricity by utilities at a fixed price for a fixed period (Couture and Gagnon, 2010). It is possible that innovation dynamics alike those seen for other technologies are in place for PV, such as Moore’s Law for micro-processors (Schaller, 1997) These cost developments may deem incentives to solar technologies a success, one of the reasons why governments are largely rolling back FIT programmes.
