Open Your Blinds and Save on Your Heat Bill
A lot of people sit in their apartments or houses with the blinds closed for privacy and don't give it a second thought.
First of all, keep in mind, people usually can't see inside during the day. The reflection of the sun usually blocks their view inside your window.
Second, open the blinds and let the sun shine in! We shouldn't be surprised that the sun can help us heat our homes in the fall and winter. It heats the whole planet!
Opening your blinds and letting in the natural heat from the sun, can increase the temperature in your home by 2 to 4 degrees. That's gonna keep your furnace from working that much harder and also give you some natural light. Therefore, you're not only saving on your heat bill, but also your 'light bill' as everyone called it when I was a kid.
