Economic Impact Analysis

The following economic projections are based on theoretical calculations using industry benchmarks and literature values:

• Potential Annual Savings: €15,000-50,000 per greenhouse*
• Yield Improvement: 8-15% through optimized control (based on literature)
• ROI: 6-18 months for GPU hardware investment
• Carbon Reduction: 20-35% through efficient operations

*Note: Savings estimate assumes:

• Medium-sized commercial greenhouse (2,000-5,000 m²)
• Energy consumption of 200-400 kWh/m²/year
• Danish energy prices of €0.30-0.40/kWh
• 10-20% energy reduction through optimization (based on literature showing 9% savings achievable)
• Energy costs representing ~50% of operational expenses

These projections are theoretical and based on optimization potential demonstrated in academic literature. Actual savings will depend on specific greenhouse characteristics, local energy prices, and successful implementation of the optimization strategies.
