Following the Army of the Loire's defeats, Gambetta turned to General Faidherbe's Army of the North. The army had achieved several small victories at towns such as Ham, La Hallue, and Amiens and was protected by the belt of fortresses in northern France, allowing Faidherbe's men to launch quick attacks against isolated Prussian units, then retreat behind the fortresses. Despite access to the armaments factories of Lille, the Army of the North suffered from severe supply difficulties, which depressed morale. In January 1871, Gambetta forced Faidherbe to march his army beyond the fortresses and engage the Prussians in open battle. The army was severely weakened by low morale, supply problems, the terrible winter weather and low troop quality, whilst general Faidherbe was unable to command due to his poor health, the result of decades of campaigning in West Africa. At the Battle of St. Quentin, the Army of the North suffered a crushing defeat and was scattered, releasing thousands of Prussian soldiers to be relocated to the East.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The belt of fortresses were in what area of France?
Ah, so.. northern France

By the end of 2011, total renewable power capacity worldwide exceeded 1,360 GW, up 8%. Renewables producing electricity accounted for almost half of the 208 GW of capacity added globally during 2011. Wind and solar photovoltaics (PV) accounted for almost 40% and 30% . Based on REN21's 2014 report, renewables contributed 19 percent to our energy consumption and 22 percent to our electricity generation in 2012 and 2013, respectively. This energy consumption is divided as 9% coming from traditional biomass, 4.2% as heat energy (non-biomass), 3.8% hydro electricity and 2% electricity from wind, solar, geothermal, and biomass.
