The Energy Monitor Shield is supplied with a Nokia 5110 LCD for displaying instantaneous power consumption etc. There is an excellent Netduino driver for the Nokia 5100 display by omar, and with a few modifications this works with the Energy Monitor Shield. I removed the backlight support and made a few other simple modifications.

Nokia_5110 Lcd = new Nokia_5110(Pins.GPIO_PIN_D3, Pins.GPIO_PIN_D6, Pins.GPIO_PIN_D5);

while (true)
{
   Lcd.Clear();
   Lcd.DrawString(0, 0, DateTime.Now.ToString("HH:mm:ss"), true);
   Lcd.DrawString(0, 1, DateTime.Now.ToString("HH:mm:ss"), true);
   Lcd.DrawString(0, 2, DateTime.Now.ToString("HH:mm:ss"), true);
   Lcd.Refresh();
   Thread.Sleep(500)
}
