All the bulbs in my home are low-energy: either LED or fluorescent (as the florescents burn out they usually get replaced with LEDs). My energy use is little – my monthly bill is usually about $20! But, I am always trying to do better: both for the environment and my pocket book.
My push now is to let the house ‘go dark’. More and more I am turning off lights except where needed for reading or writing. This has been harder than I thought it would be as my place is north facing and only has one small bedroom window and the patio glass doors – the place is dark, and even worse if there are any clouds covering the sun.
So, I’m trying harder to be better and use a little less light.
