Energy relationship

Formula

ΔkWh/year = (W_incandescent − W_LED) × h/day × 365 ÷ 1000

= 75.92

Note

This is a simplified model: it applies the standard equation to the numbers you entered and ignores real-world losses, weather variation, tariff structures and equipment tolerances. Wind power assumes air density 1.225 kg/m³ at ISA sea level and the power coefficient you enter (Betz limit 0.593). Verify with measured data or a professional energy audit before making purchasing decisions.
