4 Frequently Asked Questions about "Thermal hydropower and solar power generation ratio"

What are energy ratios?

The considered ratios are Energy Return on Investment (EROI) – standard and external, Energy Payback Time (EPT), Primary Energy Factor (PEF), and Resource Utilisation Factor (RUF). A common energy analysis framework, together with three energy accounting methods based on energy value, exergy, and primary energy, are described.

What is a high energy return on investment ratio?

High Energy Return on Investment ratios correspond to short Energy Payback Times and vice versa. Energy Ratio performance levels for renewable energy generation sources – hydro, wind, geothermal and solar – heavily rely on the quality of the primary natural resource available.

How does geothermal energy ratio work?

Geothermal Energy Ratio performance strongly depends on the enthalpy and accessibility of the reservoir. For locations in New Zealand and Alaska, the Energy Payback Time stretches to a maximum of 1.5 y. Hydro and wind also show good potential if the right geographic location with sufficient generation potential is identified.

What are the five energy ratios?

This review collates energy assessment data for the most common electricity generation methods and evaluates five Energy Ratios. The considered ratios are Energy Return on Investment (EROI) – standard and external, Energy Payback Time (EPT), Primary Energy Factor (PEF), and Resource Utilisation Factor (RUF).
