Several years ago, I worked with potato farmers – wise and pragmatic people. In springtime, they would bring some snow into their potato storages. Snow absorbs a lot of heat as it melts, so it kept the storage (and potatoes) cool, extending the life of the potatoes.
Just as snow keeps those potato storages cool, it can help you save a bit of energy and money at home:
- If you take snow or ice from outside and put it into your fridge, it will absorb heat as it melts, meaning your fridge comes on less. (That’s how ‘iceboxes’ worked in the days before fridges.)
- You can make ice cubes for free outside, giving your fridge’s freezer compartment a break. (When you pause to think about it, it’s a bit odd that we use energy to make ice in winter…)
Take advantage of FREE snow and ice to save a bit of energy and money!

The long awaited Copenhagen Climate Change Conference kicked off yesterday. It’s a critical moment, one that will test our global community’s ability – and desire – to work together to solve a problem that will impact every single human on Earth.
This week, a few visuals worth watching:
From 1992, “The Girl Who Silenced the World” http://www.youtube.com/watch?v=TQmz6Rbpnu0, a twelve year old’s powerful message to world leaders gathering for the Rio Earth Summit.
“The Story of Stuff” http://www.storyofstuff.com/, a frank look at where stuff comes from and where it ends up – worth thinking about during this ‘season of stuff’.
Yesterday I had the opportunity to speak to 500 young people about climate change. To me, their bright, young faces represent hope and promise for the future. For their sake and the sake of all youth everywhere, let’s hope our leaders gathering in Copenhagen get it right.
