Wind

Small-scale wind - 2-10 KW - residential

• 3-4 times the energy production as PV per € for build
• ~€7 to €10/watt build (after capacity factor)
• ~€0.08/kWh generated (financed)

Mid-Scale Wind Parks - up to 1 MW

• Manageable - good size for dedicated user
• Can use reconditioned equipment
• ~€5 to €7/watt build
• ~€0.04 to €0.06/kWh generated (50% financed)

Large Wind Farms - over 1 MW

• Most economic – scale matters
• ~€2 to €3/Watt build
• ~€0.02 to €0.03/kWh generated (50% financed)
• Large offshore potential

One of the issues with wind generation is storing the electricity when the wind is blowing for use when there is little wind.  This can be achieved by generating hydrogen by electrolysis and burning it when required in a fuel cell.  This is illustrated by an island project in Norway.  The current issue is the high cost of the equipment.
