1. What is the Cost per kWh Calculation?

The cost per kWh calculation compares the cost of coal-generated electricity against solar power by accounting for subsidies. It helps evaluate the true cost difference between these energy sources.

2. How Does the Calculator Work?

The calculator uses the simple equation:

Where:

• \( Coal\ Cost \) — Cost of coal-generated electricity ($/kWh)
• \( Solar\ Subsidy \) — Government subsidy for solar power ($/kWh)

Explanation: The equation shows the adjusted cost of coal power when solar subsidies are considered, helping to understand the economic competitiveness of solar energy.

3. Importance of Cost Comparison

Details: Comparing energy costs is crucial for policy decisions, investment analysis, and understanding the true economics of energy transition from fossil fuels to renewables.

4. Using the Calculator

Tips: Enter both coal cost and solar subsidy in dollars per kWh. The calculator will show the adjusted cost of coal power after accounting for solar subsidies.

5. Frequently Asked Questions (FAQ)

Q1: Why compare coal cost to solar subsidies?
A: This comparison helps understand how subsidies affect the relative economics of different energy sources.

Q2: What are typical values for coal cost?
A: Coal power typically costs $0.03-$0.15 per kWh, depending on location and plant efficiency.

Q3: How do solar subsidies vary?
A: Solar subsidies range from $0.01-$0.10 per kWh, depending on government policies and programs.

Q4: Does this account for external costs?
A: No, this simple calculation doesn't include environmental or health externalities associated with coal.

Q5: Can this be used for other energy comparisons?
A: The same principle can be applied to compare other energy sources when one receives subsidies.
