Why Wind?
Wind Propulsion Technology
is Mature and Proven
- Propulsion not Energy Efficiency
- Wind-Assist & Primary Mover
- Retrofits = 5-20% Propulsive Energy
- Optimised Wind-Assist = up to 30%
- Primary Wind New Builds = 50%++
- Retractable, Automated, Certified
The Economics of
Wind Make Sense
- Energy Cost Fixed at Zero
- Technology Available Today
- Applicable Across the Fleet
- Robust Pipeline of Tech & Projects
- Operational Changes Boost Wind
- Predictable: Weather Routing/Forecast
It’s a Renewable
Energy Source
- Abundant Energy Supply
- Available Worldwide Today Zero Emissions Energy
- Delivered at No Cost
- Delivered Directly to Point-of-Use
- No New Infrastructure Required
