To keep your coffee beans as fresh as possible, the National Coffee Association has some simple tips to ensure the first cup is as good as the last. The biggest enemies of coffee beans are air, moisture, heat and light. Use airtight, opaque containers and store them in a cool, dark spot -- inside a cabinet away from the oven is ideal. If you buy pre-ground coffee, transfer it out of the bag and into a sealed container, and try to purchase smaller batches so it stays fresher longer. And when you're done brewing, don't toss those coffee grounds -- used grounds are great for composting and can help enrich soil while keeping waste out of landfills.

If you have access to Wi-Fi when using your smartphone, use it. Wi-Fi consumes less energy than cellular data like 4G and 5G because it requires less power to transmit data to a nearby router. Cellular networks rely on energy-intensive cell towers, which can use up to twice as much energy. Using Wi-Fi can also extend your phone's battery life, thanks to the reduced energy demand.

Have a little leftover club soda or sparkling water? Don't toss it down the drain; give it to your houseplants instead! Yes, the bubbly water is hydrating for thirsty plants, and the fizzy stuff can help them thrive. The carbon dioxide and minerals in carbonated water are beneficial to plants. When the roots of the plants drink up the water, it helps them grow and repair. Obviously, regular tap water is fine for plants, but a little leftover fizzy water is something they'll love from time to time, too.
