1. What is the Cost of Coal per kWh?

The cost of coal per kWh represents the total expense to generate one kilowatt-hour of energy from coal, accounting for both the fuel cost and transportation expenses. This metric helps homeowners and energy consumers understand the true cost of coal-based energy.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Coal\ Price \) — Price of coal per ton ($/ton)
• \( Efficiency \) — Energy conversion efficiency (kWh/ton)
• \( Transport \) — Transportation cost per kWh ($/kWh)

Explanation: The equation divides the coal price by the conversion efficiency to get the fuel cost per kWh, then adds the transportation cost.

3. Importance of Cost Calculation

Details: Calculating the true cost per kWh helps in comparing energy sources, budgeting for home energy needs, and making informed decisions about energy consumption.

4. Using the Calculator

Tips: Enter the current coal price per ton, the system's efficiency (typically 2,500-3,500 kWh/ton for home systems), and transportation costs. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical efficiency value for home coal systems?
A: Most home coal systems have an efficiency between 2,500-3,500 kWh per ton of coal.

Q2: How do I find my local coal price?
A: Check with local coal suppliers or energy providers. Prices vary by region and coal quality.

Q3: Why include transportation costs?
A: Transportation can significantly impact the final cost, especially if coal needs to be shipped long distances.

Q4: How does this compare to electricity prices?
A: Compare your result to local electricity rates to determine if coal is cost-effective for your needs.

Q5: Are there other costs not included here?
A: This calculator doesn't include equipment maintenance, storage costs, or environmental fees which may apply in some areas.
