My old PC had a 400Watt power supply.
My old Halogen downlights were 50 Watts each
My laptop had a 90Watt power supply.
My new halogen downlights are 35 Watts each
My phone has a 1 watt charger. (also my tablet.)
My LED downlights use 7 Watts.
I'll stick with my gadgets and generate 1.5 KWh on average with the solar panels on the roof thanks.
