According to the U.S. Department of Energy, lighting – most of which comes from inefficient incandescent bulbs – uses about 25 percent of all electricity in the United States. Experts estimate that 47 percent of the energy used in a home is for lighting and temperature control. 

Not only does switching to natural light decrease energy usage, but research has shown that it’s effective in boosting moods and reducing stress. Natural light also provides a good dose of vitamin D, which is essential for maintaining healthy bones and teeth and lowering the risk of conditions such as multiple sclerosis, Type 1 diabetes and cancer.
