Manu: maybe we should explicitly consider reuse of M&I water and also desalination options for a richer water-energy story

TODO: Consistent estimate of land value when optimizing renewable energy land use.

let us talk about these since the question is very interesting and we need some parameters to see if it makes much of an impact on the energy system at all or not

read the document and key question that comes out is the following 1) We are still operating the model at a monthly time step, and at county, i.e. we need to develop some estimates of the potential of renewable energy and the demand at monthly steps -- which is not the scale at which the grid optimization people work -- they are trying to manage transmission + load balancing at the hour or less -- but for grid design this is not necessarily very efficient (computationally) so they are working on sophisticated math optimization algorithms 2) I think what we are doing is really a planning/screening model and not a design model, so we need to make that clear when we talk. However, David F is finding that there is a strong correlation between renewable supply + demand when wind, solar and rain are considered on the supply side and heating/cooling is considered as the major demand (and it is). At the monthly scale, this would mean that we need to (for each county) consider a standard wind turbine (e.g., 2MW) and a m^2 solar panel and work up the day/night potential production from hourly data and then have this aggregated to a month, and solve for how many of these turbines/panels are needed as a function of 2 or 3 time segments of each day that are considered, including any imports (e.g. if we only consider solar, we need a source for the night) -- we could also parameterize these as a diurnal cycle and then aggregate. Further, David shows that there is decadal (years) fluctuation in the seasonally aggregated values of the same variables = peak to peak decadal fluctuation = as much as 30% to 40% of long term mean in many cases -- well beyond what a battery could handle and this could be handled by transmission or by reformed fossil fuels (CO2--> hydrocarbon)

point being that arguing that these kind of features need to be highlighted as the issue

I expect that we may activate some but not all components of AWASH at a time to get a particular point across -- it is a learning model
