An easy, one-time way to a greener 2019 and beyond is shifting all your lighting to LED. Compared with incandescent bulbs, LEDs deliver the same quality of light but use 40% less energy. They also last a lot longer, some being good for 25 years while incandescents can only survive 365 days. While LED bulbs do cost more – a pack of four goes for $20 – they ultimately save you money. When used eight hours a day, every day, incandescent bulbs cost roughly $23 a year whereas LED costs $4 a year. If you're looking for a truly easy way to green 2019, LEDs will do the trick.
