Here's a cool idea

What if... we all bought new fridges?

Sure, it sounds expensive but you are actually saving money.

The energy use of refrigerators and freezers has improved dramatically in the past 20 years, but they are still among the largest energy consumers in the home. A typical new refrigerator today uses less than 500 kWh per year, a running cost of about $25.00 a year, again assuming $0.045/Kwh. A typical model sold in 1973 used more than three times as much 1500Kwh/year or $75.00. The typical unit today is larger, has better controls, and increased efficiency achieved through improved compressors and motors.

I got most of these figures by doing some simple research on some conservation sites, so both the research and me being simple, the math is simple. A new basic fridge cost $600...ish, you save $50 a year in hydro, fridge pays for itself in 12 years.

Sounds like a long time, but think of it this way. You have a brand new fridge, and it is paying for itself when compared to your old fridge. If you didn't get a shiney new fridge you would still have an old ugly avocado green fridge for the cost of $50 more a year... see my logic. The new fridge is cheaper... sort of???

The return will be quicker if they increase our Hydro rates... and you know that will happen. I have not included electrical delivery costs because all things being equal, you would have to pay that regardless.

CANDU 6 rant. (Cost 3 billion dollars, 700 Mwh)

Lets do a yearly average this time. If we replaced every fridge in Ontario homes with new ones, at 4.5 million households in Ontario, we could save about 4500 Mwh every year or roughly 500Kw every hour of every day.

That's a consumer cost of $22,500 every hour.

If every Ontario household got a $500 credit towards a new fridge, it would cost 2.25 billion dollars. If would be recovered in 100,000 hours, or about 12 years.

Same cost and return as if we bought it, coincidence... I think not!

I have messed with the numbers, but the return is not as great as replacing all your bulbs with CFB's. You use about the same amount of power yearly to run a fridge as you do for normal house lighting. But it cost a lot less to replace house lights ($20) than a fridge ($500).

My point is... conservation is still cheaper than building a new reactor.

BTW... I am pro Nuclear, there is no other choice except conservation.

I thought fridge was a metaphor for something else....

I agree with most of your technorants, and also agree with nuclear. But I disagree that there is no other alternative. For instance, Denmark gets about 23% of its energy from wind turbines.
