With 5% turnover and 7% of the working population it’s the Achilles heel of the islands economy, which is amongst the least industrialised of France. Subject to its insular limitations the region has never shown a real industrial calling and is not prepared to develop a manufacturing department.

The aeronautic line imported from the continent a bit of industrial metal works, agricultural food products and a small wood tobacco and cork industry, resume the secondary section of the island or 30 businesses with more than 20 employees, or with an individual employing more than 100 people. Construction deserves to be mentioned because it represents about 10% of the jobs in the service industry, the majority of the electricity production comes from 2 diesel powered centrals installed at Luciana by Bastia and Vazzio by Ajaccio. What's more 7 damns feed the hydraulic centrals especially around Calacuccia and Prunelli. The rest comes by under water cable from Italy. Windmills installed in 2000 should allow substantial energy cost to house holds.
