A little more than 3,500 gigawatt hours exported, because Sardinia doesn't need them. Digging into the numbers, which are not secret at all, we can already find signs of energy colonialism, to which the assault of renewables is acting as a sounding board due to an electrical surplus destined to become abnormal.

The result is an Island, ours, increasingly an energy slipper of Italy. "With the risk - underlines the industrial engineer Giovanni Cossu - of paying the very high price of environmental devastation".

The starting point is precisely the difference between current gross production and consumption. The first is worth 12,563.1 gigawatt hours. Divided as follows: 8,621.6 from thermoelectric; 1,935.6 from wind; 1,520.9 from solar; 483.5 from hydroelectric; 1.5 from storage plants. But the Sardinians and industries, all together, have a requirement that stops at 7,636.9 gigawatt hours . The 3,508.3 that end up outside Sardinia are reached with a whole series of subtractions. Including the 507.8 gigawatt hours of losses. The result, however, does not change: energy exports are equal to 27.92% of the quantity produced.
