1. What is Wind Turbine ROI?

Return on Investment (ROI) for wind turbines measures the financial return relative to the cost of the investment. It helps determine how profitable a wind turbine installation will be over time.

2. How Does the Calculator Work?

The calculator uses the ROI formula:

Where:

• \( Energy\ Saved \) — Energy produced by the turbine (kWh)
• \( Price \) — Price per kWh of energy (currency/kWh)
• \( Cost \) — Initial investment cost (currency)

Explanation: The equation calculates the percentage return on your wind turbine investment based on energy savings and initial costs.

3. Importance of ROI Calculation

Details: Calculating ROI helps investors and homeowners determine the financial viability of wind turbine installations and compare different renewable energy options.

4. Using the Calculator

Tips: Enter energy saved in kWh, price per kWh in your local currency, and the initial cost of the wind turbine installation. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a good ROI for wind turbines?
A: Typically, ROI above 10% is considered good, but this varies by location, energy prices, and installation costs.

Q2: How long does it take to break even on a wind turbine?
A: Payback periods typically range from 5-15 years depending on turbine size, wind resources, and energy costs.

Q3: What factors affect wind turbine ROI?
A: Key factors include wind speed at your location, turbine efficiency, maintenance costs, energy prices, and government incentives.

Q4: Should I include maintenance costs in the calculation?
A: For more accurate results, subtract annual maintenance costs from your energy savings before calculating ROI.

Q5: How does turbine size affect ROI?
A: Larger turbines generally have better ROI due to economies of scale, but require higher upfront investment and suitable sites.
