Other comments from users:

"Elegant, useful, very informative. Well done."

"I thought it was very thorough.  I am LEED AP and Green Point Rater, so I am pretty familiar with the topic.  I do my best to minimize my energy use, but somethings are not my control ... It was very useful for me."

"Great analysis. should be available to every household."

"I really like what you've done. I work in the commercial energy management software space (non-intrusive load disaggregation). Your coarse analytics with just utility data is superb. Keep up the good work--I hope it's catching on!"

“It was perfect. I love it!”

"I can't believe how helpful this has already been. $115 PG&E bill this months !! It hasn't been that low in the 15 years we've owned this house. You've convinced me to buy an energystar fridge as I can see a fairly short payback period."

“Extremely informative and a real eye-opener. I knew in our house we were wasting energy, but I had NO idea how much.”

"I found the information useful as presented."

"A really great app, this service provides useful data about my home! Thank you for putting this together!"

“Even in a household without High Energy usage there are still steps I can take. Thanks. Far more useful than I expected.”

“Great job, very easy.”

"This was highly informative and eye opening. I'm glad to know we are a low energy user. It makes sweating in the summer, and bundling up with more clothes on in the house in winter, worthwhile on many levels."

"Good job. Like where this is going."
