Hi Daniel,

Thank you for submitting your contest proposal.

I’m a Climate CoLab Impact Assessment Fellow who specializes in energy. I was hoping to conduct an  impact assessment of your proposal, but I do not have access to the EMERGE tool which you mention. Without this, I personally cannot assess the potential impact of this proposal, since it varies by country. Would you be willing or able to conduct an assessment for your proposal? If you have any questions or suggestions, you can contact me at @negah.

Congratulations on making the semi-finals!

The Energy Model for Emerging Renewable Generation with Eco-environmental analysis (EMERGE) tool looks amazing. Will it be proprietary or open-source? I would suggest open source so people can collaborate and build upon it.

How are you getting all that detailed information? Is there a standard estimate or will all that information be defined in a custom manner?

Have you seen the work of Joe Levy (@jonlevyBU) at Boston University on energy and health?

Will you leverage that kind of work?

Good luck,



Daniel Howard

Hi Negah,

So nice to hear from you.  I did not see your message until a few days ago, please excuse my delay.

EMERGE is being developed to be open source, yet I have not yet published it and am still refining it and making it easier to use.  

I would be more than happy to conduct an assessment for any country that  we can get data for.  What country/region would you like assessed?

Hi Perry,

Thank you for the great suggestions.

Yes, EMERGE will be published open source :)

There's two methodologies I'm using to get results and quantify uncertainty.  EMERGE uses reduced-form equations based on country specific LCA studies (standard estiamtes).  The other uses an integrated methodology of 3 industry standard models:  Plexos, CALPUFF and BenMAP (custom data).  Data is collected from a variety of sources, including power plant data from my colleagues at the Federal University of Rio de Janeiro, meteorological WRF data from Lakes Environmental, and I'm going to be spending this summer with the BenMAP team at the EPA.

Thank you for bringing up Joe Levy!  I've studied his work on power plants in Illinois and China, they use the CALPUFF atomospheric dispersion model, which helped me develop the integrated modeling methodology above to quantify the uncertainty of EMERGE.

Take care
