April 22, 2015 marks the 45th anniversary of Earth Day, a worldwide event founded to educate the public about global warming and inspire appreciation towards the environment. Environmental responsibility has been growing in popularity throughout the world, and you can take part in the conscious trend, too. Here are three ways to celebrate Earth Day:

Turn off the lights—According to Innov8Energy, “If we all turned off two lights in our homes for only one hour every day, collectively, we would save more than 5 million kilowatt hours of electricity nationwide, each year.” That’s a lot of energy we’d be saving. Remember to turn off the lights after you leave the room.

Recycle—One of the easiest actions of environmental responsibility is recycling. According to dosomething.org, “Over 75 percent of waste is recyclable, but we only recycle about 30 percent of it.” Take part in a local recycling program and recycle your paper, plastics, glass and aluminum cans.

Reduce Vampire Power—Did you realize that your T.V., your microwave, your refrigerator are all using power 24 hours a day? It’s called “Vampire Power” because these electronics are sneakily sucking energy. Unplug your computers, your phone chargers and other electronics to cut the current when you’re not using them. The environment, and your energy bill, will thank you.
