Earth Hour events

• Ontario Science Centre celebrates Earth Hour with free activities: environmentally themed storytelling; music and art; telescopic observations of Mars and Saturn; dancing to the stars with an Earth Hour DJ set and more. Mar. 29 from 8 p.m. 770 Don Mills Rd. 416-696-3127 or OntarioScienceCentre.ca.
  

Bystanders are also welcome to do the "Twist" and produce enough human-generated power to light up CFL and LED lights, and even transistor radios, using "disco-generators." Brothers Lorrie and Lloyd Matchett will be demonstrating the invention starting at 5:30 p.m. and all evening outside the Science Centre.

• Earth Hour at the Observatory features astrophysicist Tom Bolton's lecture "Light Pollution — How Richmond Hill Tamed the Light Bulb" at 7 p.m., plus a tour of the facility's Administrative Building. That's followed at 8 p.m. with some outdoor telescopic viewing and tours of the night sky, and a sacred aboriginal ceremony with David Grey Eagle and his People. David Dunlap Observatory, 123 Hillsview Dr. Richmond Hill. savetheddo.org.

• Light your house with clear Christmas LED energy-efficient lights all year long.
• Put air in your tires. Well-inflated tires save gas and stay in good shape for a longer period.
• Make fewer left turns. You'll spend less time idling in the turn lane.
• Don't limit yourself to a green bin in your kitchen. Keep one in your bathroom and recycle used tissues, toenail clippings, etc.
• Get in shape and run your electronics at the same time. Hook up a generator to your exercise bike (Google it to get instructions) and power things like computers, toasters and blenders.
• Avoid washing some of your clothing altogether – really. Do this with jeans; you'll run your washer and dryer less, and it will mean expensive jeans will mould to your body and take longer to fade.
• Buy a smaller home. They require less energy to heat and cool.
