Electricity Data Explorer App: Background

With a wordwide focus on our electicity generation capacity and usage footprint this application aims to make it easier to visualise various electicity patterns for the world on a world map.

Electricity Data Explorer app consists out of two sub applications, a Data Explorer and a Consumption Calculator. The usage of the two apps will be detailled in the next couple of slides.

Data Explorer App

This app uses the googleVis library to visualize data from the US Energy Information Administration site. The user needs to select the year using the zyear slider and select the dataset to show using the dataset selectionbox. Once the user clicks 'submit` button a world map with the selection and a grid with the raw data will render on the right hand side. A full description of the dataset being viewed and the source of the information is also displayed at the bottom.

The first version of this app shows the following datasets from 2000 - 2012:

• Electricity Distribution Loss
• Electricity Nett Consumption
• Total Electricity Installed Capacity
• Electricity Nett Generation

Consumption Calculator App

A basic electricity comsumption calculator based on a couple of the major electricity consuming applicances in a household.

The user needs to input the average hours per day and the typical Watts that the applicance use. Once the users clicks on the submit button a grid with the usage for each item will be displayed on the right hand side.

disclamer: The total usage calculated on this app will not resemble the your monthly usage as the app deosnt take in to account all the appliances in a house.

Example Calculation

As a basic example lets calculate the monthly electricity consumption for a standard 200Watt applicance that is used for 2 hours a day.

        avgDaysMonth <- 365/12
        applianceWatt <- 200
        dayUsage <- 2
        monthKWh <- ((applianceWatt/1000)*dayUsage)*avgDaysMonth
        monthKWh        

## [1] 12.16667

Thus a 200W appliance that is switched on for 2 hours a day will use 12.17 KWh per month.
