## Online Calculators & Illustrative Numerical Energy Tools

Below are listed a number of simple online calculators.

You are welcome to use them in a standalone manner – and hopefully find them useful – but note that most were developed in conjunction with other online content (training or articles, as indicated). So you may want to visit that content too, for further explanation of their context and/or ideas on how best to use them.

### Levelised Cost of Energy (LCOE)

A tool to calculate LCOE in two ways: a “simple” and a “leveraged” method, including a graphical illustration of the contributing factors.

Associated with online course: Essentials of Power Generation Markets (“Project Economics & Energy Costs” chapter)

### EV Energy & Emissions

How much electricity generation will electric vehicles require and how will their carbon emissions compare with conventional cars?

Associated with article: EVs and Electricity Demand

### Merit Order Illustrator

A simple graphical illustration of how a “merit order” of electricity supply meets an electricity demand curve to produce a changing wholesale market price.

Associated with online course: Essentials of Power Generation Markets (“Project Economics & Energy Costs” chapter)

### Power, Energy & Time

The relationship between power (W), energy (Wh) and time, covering different timescales (from seconds to days) and different power/energy scales (kW to TWh).

Associated with online course: Essentials of Power Generation Markets (“Power, Energy & Capacity” chapter)

### Calculations with Capacity Factor

Illustrating how variations in capacity factor between different power projects impact their economics.

Associated with online course: Essentials of Power Generation Markets (“Capacity Factor” chapter)

### Primary Energy & Efficiency

Simple calculations around primary energy and power conversion efficiency; also including capacity factor and the impacts of these various inputs on some simple economic outcomes for power projects.

Associated with online course: Essentials of Power Generation Markets (“Efficiency in Power Systems” chapter)

### Primary Energy Comparisons

Compare the primary energy consumption of any two countries included in BP’s Statistical Review of World Energy 2016.
