Generating electricity from onshore wind is cheaper than gas, coal and nuclear when externalities are stacked with the levelised cost of energy and subsidies, according to an Ecofys study ordered and endorsed by the European Commission.
Based on EWEA's analysis of the data in the report, onshore wind has an approximate cost of EUR 105 per megawatt hour (MWh) which is cheaper than gas (up to EUR 164), nuclear (EUR 133) and coal (between EUR 162-233). Offshore wind comes in at EUR 186 and solar PV has a cost of around EUR 217 per MWh.
The total cost of energy production, which factors in externalities such as air quality, climate change and human toxicity among others, shows that coal is more expensive than the highest retail electricity price in the EU. The report puts the figure of external costs of the EU's energy mix in 2012 at between EUR 150 and EUR 310 billion.
Justin Wilkes, deputy chief executive officer of the European Wind Energy Association, said: "This report highlights the true cost of Europe's dependence on fossil fuels. Renewables are regularly denigrated for being too expensive and a drain on the taxpayer. Not only does the Commission's report show the alarming cost of coal but it also presents onshore wind as both cheaper and more environmentally-friendly."
Onshore and offshore wind technologies also have room for significant cost reduction. Coal on the other hand is a fully mature technology and is unlikely to reduce costs any further.
He added: "We are heavily subsidising the dirtiest form of electricity generation while proponents use coal's supposed affordability as a justification for its continued use. The irony is that coal is the most expensive form of energy in the European Union. This report shows that we should use the 2030 climate and energy package as a foundation for increasing the use of wind energy in Europe to improve our competitiveness, security and environment."
