Quick Fridge Trips Will Cut Your Energy Use
How many times have you or your kids stood staring in front of the open refrigerator door looking for something to eat?
Those food reveries can be costly: An article in Home Energy magazine says that refrigerator door openings account for 7 percent of your appliance's energy use.
The cold air that keeps your food fresh flows out the door and is replaced by warm air from the kitchen. Then the refrigerator compressor has to work to drive the warm air out and bring temperatures down. All this elevates your monthly energy bills and your environmental footprint.
Worse, the Institute of Food and Agricultural Sciences at the University of Florida says that poor open/close habits—like leaving the fridge door open while pouring milk in your cereal— waste 50 kilowatt hour (kWh) to 120 kWh a year.
In the long run, 50 kWh of energy saved could run your dishwasher 20 times and 100 kWh could run your washing machine 50 times. That's almost a free load of laundry every week for an entire year.

Earth had its second-warmest year on record in 2020, just 0.02 degrees Celsius (0.04°F) behind the record set in 2016, and 0.98 degrees Celsius (1.76°F) above the 20th-century average, NOAA reported January 14.
Figure 1. Departure of temperature from average for 2020, the second-warmest year the globe has seen since record-keeping began in 1880, according to NOAA. Record-high annual temperatures over land and ocean surfaces were measured across parts of Europe, Asia, southern North America, South America, and across parts of the Atlantic, Indian, and Pacific oceans. No land or ocean areas were record cold for the year. NOAA National Centers for Environmental Information

In December of 1924, the heads of all the major lightbulb manufacturers across the world met in Geneva to concoct a sinister plan. Their talks outlined limits on how long all of their lightbulbs would last. The idea is that if their bulbs failed quickly customers would have to buy more of their product. In this video, we're going to unpack this idea of purposefully creating inferior products to drive sales, a symptom of late-stage capitalism that has since been coined planned obsolescence. And as we'll see, this obsolescence can have drastic consequences on our wallets, waste streams, and even our climate.
