Earth Hour is taking place tonight from 8:30 p.m. to 9:30 p.m. local time all around the world.
Here are just some of the ways you can have a clean and green Earth Hour in 2015.
1. Stop using the dryer
Instead, Anderson recommended using the "the big one up in the sky" for any necessary drying.
2. Avoid using the fridge
Anderson said it's important to carefully consider before using the fridge and open the door as little as possible.
"I put tape over the latch for the light," he said.
3. Use shade to lower cooling costs
"Plant Larch or Deciduous trees on south side of your house," Anderson said.
He explained that this allows solar gain during winter months while lowering cooling costs in the summer.
4. Smart thermostats
A programmable thermostat can save 20 to 25 per cent on your overall energy bill.
And don't forget to wear a sweater instead of raising the temperature.
5. Smart power bars
Purchase smart power bars and connect them to TVs in order to prevent ghost power loss.
"The model I have switches on the power to my TV when my remote sends out a infrared signal," Anderson said. "When it senses a reduction in current on that outlet, it will switch off power to that outlet and a few others as well."
6. Change light bulbs to LEDs
Change incandescent and fluorescent bulbs to LEDs as they burn out or as the new ones go on sale.
7. Use solar panels
Use solar panels and solar hot water panels, which preheat the water from ground temperature before it hits your hot water tank.
8. Beware of vampire power
If your charger is plugged in and not charging a device, it still draws power.
9. Use frozen water for cooling
In winter, fill a couple of milk jugs full of water, then put them outside to freeze. Bring one in and put it in the fridge. Exchange them every second day to help the fridge stay cool without having to work so hard.
10. SaskPower programs
