1. Why replacing incandescent lightbulb(s) with Energy Star-certified LED?
I wanted to do my part in saving the energy the world consumes every day. LED reduces energy consumption as they use 90% less energy than regular bulbs, as they work like solar panels in reverse. Although they are three times more expensive than incandescent bulbs, they last much longer. I believe the price is worth the results and the difference it makes for the environment.
"LEDs (light-emitting diodes) are the most energy-efficient bulbs available. Unlike older technologies, they transfer most of their energy use into light, rather than waste heat" (Project Drawdown Solutions).
2. Do I really need a car if I live and work in a city or can I go by bike as many times as possible?
I live in a city with many cars where drivers complain about wasting time in traffic. I am a big fan of biking in cities as I I always get to my destination first, avoiding traffic or running into public transportation issues. Moreover, the health benefits are well known, as physical activities reduce all sorts of common diseases. If infrastructures are well designed, cities can reduce many car trips by encouraging their residents to use bicycles instead. I like the commodity of biking everywhere in the city I live in, while saving money at the same time by not using a car.
"Bicycles offer an alternative to cars and fossil-fuel transport, especially in cities. Infrastructure is essential for supporting safe and abundant bicycle use, thereby curbing emissions" (Project Drawdown Solutions).
