When it comes to home improvements, windows can have a huge impact on your energy efficiency and therefore your heating and cooling costs. The quality and type of windows you have in your home significantly affects electricity usage within your home. If you’re thinking about replacing your windows, consider purchasing ENERGY STAR qualified windows, which use multiple panes and various coating technologies to decrease energy use and increase comfort inside your home. If you aren’t able to replace windows, there are a number of other techniques you can use to cut electricity costs, such as adding blinds or shades inside, or reflective film or solar screens outside.
