Let’s look at energy waste that happens at home. How many people are still using old incandescent bulbs these days? Do you know that they waste more than 90% electricity because their energy is more heat energy than light? Instead you should be changing out your lights to GU10 LED Bulbs. These put out 100% light, and last up to five years, longer if you are smart and do things like turn off the lights in a room when you don’t need it.
