Install a clothesline
A simple clothesline allows you to dry your clothes for free using the power of the sun instead of expensive electricity. Electric clothes dryers can really put a dent in your wallet, especially if you have a large household. While a clothesline does require a bit of manual labour to hang the clothes, you will enjoy a fresh, natural smell in your laundry as well as a reduced utility bill.
Repurpose old jars and containers for free garage storage
Back in the day, it was common for grandfathers to organise their hardware in glass jars. The simple practice entailed fastening the lid to a shelf bottom and simply screwing on the jar. Other useful containers for free storage include laundry soap bottles, shoeboxes and many more. Use your creativity and keep these items out of the landfill. Books can look beautiful as repurposed items like as a knife block, too.
Install a ductless mini split HVAC system
When it is time to replace your HVAC system, consider switching to a ductless mini-split. The super-efficient systems require less labour during installation, do not require air ducts and allow you to cool/heat your home in zones instead of the entire house. This can have a profound effect on your energy costs in a good way.
