The traditional incandescent light bulb patented in the late 1800s was no doubt a civilization-changing invention, but ultimately not the most efficient producer of visible light - in fact, these bulbs can be described as little thermal space heaters with only 10% light production! Nowadays our bulb choices are much more varied, with the most efficient and energy-saving option being LED bulbs which last much longer and emit very little heat. Since most of our electricity is powered by coal, gas, and oil, we could all make an impact on reducing CO2 emissions from these sources by replacing home, business, school, and church lighting with LED bulbs - our Week #23 Way to Care for Creation. “Believers themselves must constantly feel challenged to live in a way consonant with their faith and not to contradict it by their actions. They need to be encouraged to be ever open to God’s grace and to draw constantly from their deepest convictions about love, justice and peace” [LS 200].
