Green product premium saving calculator

The price-premium difference values equal energy coverage without establishing equal environmental claims.

ΔC=E×(pgreen−pREC)\Delta C = E \times \left(p_{\text{green}} - p_{\text{REC}}\right)

Worked example

Given

  • EE = 300,000 kWh/yr
  • pgreenp_{\text{green}} = 0.03 $/kWh
  • pRECp_{\text{REC}} = 0.012 $/kWh
ΔC=300,000×(0.03−0.012)=5,400\Delta C = 300{,}000 \times \left(0.03 - 0.012\right) = 5{,}400
