+### Energy driver in Berry
+
+Since v14.2.0, it is possible to implement an Energy driver in pure Berry. The Berry driver is enabled when an `OPTION_A 9` GPIO is configured:
+
+- by default, the energy driver has zero consumption.
+- the berry code can is `energy.driver_enabled()` to check if the virtual Berry Energy driver is active (i.e. `OPTION_A 9` is configured)
+- the following values need to be configured: `energy.phase_count` (default `1`), `energy.voltage`, `energy.current`, `energy.power_factor` (typically `1.0` or less), `energy.frequency` (default `nan`)
+- the most important value is `energy.active_power` (in Watt) which is added to the daily power consumptio
+
+Example test code in `autoexec.be`:
+
+```berry
+if energy.driver_enabled()
+  energy.phase_count = 1
+  energy.voltage = 240
+  energy.power_factor = 1.0
+  energy.current = 1.5
+  energy.frequency = 50
+  energy.active_power = 360
+end
+```

 ### `wire` object for I^2^C
 
 Berry Scripting provides 2 objects: `wire1` and `wire2` to communicate with both I^2^C buses.
