Displaying Energy Scripts Outline

1. Java scripts harvest data directly from Modbus
2. Perl scripts collect this data and put it in the Postgress database "energy" under the table "electrical_energy"

   electrical_energy attributes:

   area - what building.

   preal - kW hours for that instant.

   date - date of harvest.

3. A final perl script accesses this data and generates a .png graph using the Google graph API
4. The images generated (day, week, month, year) are put in a html frame on a page to display the data.
