we have two types of widgets right now! http://blog.wattzon.com/200...

you can put one that shows your power print, and then one that allows you to embed an energy consumption label into your website/blog/etc. what else would you like to see?

Going with the above numbers, and looking at embodied energy, 715,500 joules are embodied in the paper cup where 20,033,899 joules are in the travel mug. That means there is 30 times more energy in the travel mug -- another way to think about it, you have to keep a travel mug for 30 times the lifespan of what you think the lifespan of a paper cup; if you think that a paper cup lasts a week, then use the mug for more than 30 weeks to do better (without using a paper cup). Looking at it the from the other end, if you think a travel mug lasts 10 years, then you have to (somehow) get the lifespan of the paper cup to be greater than 4 months. That means reusing it over and over, and only using one paper cup, those entire 4 months.

What's the foam cup you're thinking about? Let's run the numbers, and let's see if it is an acceptable choice.

i'm not going to provide any answers, but just more questions that we at wattzon are tackling with. i've been reading http://cheaplikeme.wordpres... lately as i do some more research, and trying to estimate the water use (as well as doing some experiments ourselves). there is also the questions of the energy impact of the soap, possibly heating the water, whether you use a dishwasher or not, etc.

all i can say is that i completely agree that its missing from the analysis... unfortunately, right now, the wattzon tools don't take into account water use (but we are working on improving that toolset).
