Skylights are one way in which we can help the environment. These may be a more expensive solution, but they will offer long term help to the environment. Skylights are essentially a window which is installed into the roof of your home.
Skylights can help the environment due to the fact they allow more natural light into your home. Therefore meaning you will not need your indoor lights on as often due to the extra natural lighting.
As well as sourcing you with more natural lighting, skylights also provide another heat source. With skylights helping to heat your home naturally, it means you will not need to use your heating as often. Which again means you will be helping the environment by using natural sources.
By using both of these natural sources of light and heat through your skylights, you will be helping the environment. It may only be small, but every little bit of help can make a huge difference overall.
