Non Technical Summary
Again, I will describe the rationale and significance separately for the three areas. In previous research, we have shown that solar energy can be economically viable without subsidy if it has a level playing field with coal based electric power in Indiana. The level playing field involves removing the solar tax credit (not available to coal power), enabling depreciation of solar investments (available to coal power), and adding a carbon tax on coal power. Thus, solar power has significant potential to develop in the US with policy and institutional arrangements in place conducive to solar development. In this research, we will evaluate and develop effective mechanisms to increase solar deployment. Having these mechanisms in place will permit greater renewable energy penetration and reduce our nation's carbon footprint. The greatest potential for future biofuels development is in the aviation sector because other options to reduce greenhouse gas emissions are not available in aviation. Both the military and civil aviation sectors have expressed great interest in aviation biofuels. In this research, we will evaluate the economic viability of different pathways and the impact of alternative government policies that could support aviation biofuels. Reducing risk for private sector investors is key, so we will evaluate the risk reduction impact of different government policy alternatives. Measuring land use change induced by biofuels has improved significantly over the past five years. However, one area that needs more work is better estimating what happens on the intensive margin (double cropping, etc.) when commodity prices increase. That is what we will accomplish in this research. With a better handle on the changes on the intensive margin, we will be able to more accurately estimate induced land use changes due to a biofuel shock. The evidence suggests that a significant fraction of the change over the past decade was on the intensive margin, so better incorporating that evidence likely will reduce total land use impacts. That is very important to estimating the total GHG impacts of biofuels

Goals / Objectives
The three objectives follow directly from the problem statement:1) Develop new contractual, institutional, and policy mechanisms that can improve deployment of solar and wind energy.2) Estimate the economics, life cycle GHG emissions, and long-run potential for aviation biofuels from a wide range of feedstocks and conversion technologies.3) Modify GTAP so that it better handles land use change at the intensive margin, and calibrate the model parameters to the actual changes that have occurred over the past decade.
Project Methods
Obj1:In prior research we have shown that the economic viability of solar energy depends critically on the tax rules applicable to the solar investment.Leasing has taken off in California partly because California electricity prices are quite high but also because solar leasing companies have been able to offer attractive options to homeowners.Leasing companies can depreciate the solar investment whereas homeowners cannot.In work on Indiana we show that solar is much more attractive for businesses that can depreciate the solar investment than for homeowners who cannot.This prior research was done using stochastic techno-economic analysis with Excel spreadsheets being used to develop the models and with the add-in @Risk to handle the uncertainty.We will use a similar approach in future work.In addition, we will bring in data on solar isolation and historic electricity prices by hour to enable us to explore the impacts of different contracting mechanisms and different approaches to net metering.For some of the future research, the simulations will need to be done on an hourly basis instead of an annual basis as was done previously.We will explore the possibility of including real options in the research plan as wellBecause non-profits cannot take advantage of any of the tax benefits,we will explore mechanisms to permit entities with tax appetite to make the initial investment and be paid by non-profits on terms similar to a lease.The term equity-swap also is sometimes used for these arrangements.Our prior research and communications with Rural Electric Cooperatives suggest that these innovative financing mechanisms will be key to obtaining more rapid solar deployment.We will also explore the impacts of alternative means of implementing net metering on the economics of solar systems.This activity also will include examination of ways to include measures of the costs solar users impose on the overall system, so as to develop net metering systems that make sense both from a systems perspective and from the perspective of a solar user.We will also examine other policy options such as a carbon tax on grid electricity.Obj2:The stochastic techno-economic analysis is an input to the ICAO/AFTF work and also part of our general assessment of aviation biofuel economics and policy options.For the stochastic techno-economic analysis, we will develop techno-economic spreadsheets for each conversion pathway.These will be done using the Palisade Systems Excel add-in called @Risk.Normally, key parameters will be identified for the risk analysis.For example, in a recent study of the corn stover to jet pathway, the key uncertain variables were feedstock cost, conversion efficiency(yield),hydrogen cost, capital cost, and future aviation biofuel prices.Sometimes the Delphi technique is used to query experts for distribution parameters.Other sources include data from experiments conducted in the field or from the literature.The output of the risk analysis is the distribution of net present value(NPV),internal rate of return(IRR),and the probability the investment will lose money.In addition, we will estimate the distribution of breakeven prices for each pathway and then conduct stochastic dominance on the breakeven price distributions.Being able to provide a distribution of financial outputs is immensely valuable to private sector investors and other players.The analysis outputs can also be used to help target future research to areas where the research outcome could be expected to have a high payoff.We also will be able to use the stochastic approach to estimate distributions of expected GHG emissions for each candidate pathway.Conversion efficiency affects the amount of products produced and associated GHG emissions.By incorporating uncertainty in conversion efficiency, we will be able to translate that into corresponding GHG emissions uncertainty.Obj3:Induced or indirect land use change due to biofuel production is often evaluated using what are called computable general equilibrium(CGE)models.One model that has been widely used is the Global Trade Analysis Project(GTAP)model developed at Purdue University[5-7,16,17,19-22].This model has been modified to trace allocation of land resources (including forest, pasture and cropland) by country and Agro-ecological Zone(AEZ)at the global scale and to model biofuel industry interaction with other economic activities.We begin discussion on induced land use changes by explaining the logic behind the land use changes induced by an increase in demand for an agricultural commodity for production of biofuels.When there is an increase in demand for a commodity(e.g.,maize,rapeseed,etc.),that demand increase causes an increase in the price of the commodity unless the commodity supply is perfectly elastic.The price increase causes some combination of five market mediated responses:With a higher price, consumption normally would fall.With a higher price for this commodity, there can be switching among crops so that more of this crop is produced and less of other crops.With a higher demand for this commodity, more cropland can be needed to meet that increased demand, and this cropland can come from pasture or forest converted to cropland.This is referred to as a change on the extensive margin.With the higher commodity demand, the existing cropland might be farmed more intensively such as via double cropping or irrigation or other investments in increased productivity.This is referred to as a change on the intensive margin.An increase in intensive margin on existing cropland reduces demand for land conversion(from either forest or pasture to cropland).With higher demand for this commodity for biofuels, there can be impacts on international trade of the commodity and of other substitution commodities.The greatest weakness in the GTAP model and other CGE models is in their handling of changes on the intensive margin.Part of the reason for this has been lack of data on things like change in irrigated area and double cropping.Recently, the distinction between irrigated and dryland crop production has been added to GTAP[15].However, double cropping is not something that has been explicitly included in GTAP or other similar models.Recent work by Babcock and Iqbal[2]has provided estimates of the extent to which the increase in global harvested area has come from double cropping(a factor which affects the intensive margin significantly)and the extent to which it has come from land conversion.This work was made possible by the substantial increase in global harvested area (about 40 million hectares) since 2006[18,24].What Babcock and Iqbal did was to try to estimate what fraction of that increase was due to double (or triple) cropping.They concluded that a substantial portion of the increase was from double cropping.What we propose to do is to add to GTAP the capacity to handle much better this part of the intensive margin, similar to previous work by Taheripour and Tyner on the ETA parameter in GTAP[19][22].We will introduce a new regionalized parameter to explicitly introduce changes at the intensive margin such as double cropping into the GTAP data base.We will call this parameter IMF (intensive margin factor), which would represent the extent of changes at the intensive margin that have been observed by region.The model will be restructured to introduce the impact of IMF on the yield price elasticity(YDEL)parameter[9].If a region has shown no increase in double cropping or other changes at the intensive margin, then the IMF would not affect YDEL, and the standard yield response would apply.If a region had shown a significant degree of intensive margin changes such as double cropping, then the IMF parameter will serve to revise the initial values of YDEL depending on the magnitude of change.Thus, we would be able to calibrate the model to the actual experience in changes in planted area over the past decade.

Target Audience:Federal and state legislators and public policy leaders in government agencies includinng EPA, USDA, and DOE. Changes/Problems:This project is being terminated due to the very untimely death of Dr. Tyner. Just prior to his death, he was elected in July 2019 a Fellow in the Agricultural and Applied Economics Association for his long, productive research and educational career in public policy. What opportunities for training and professional development has the project provided?Unfortunately, Dr. Tyner passed away very unexpectedly in September 2019. His graduate students have been reassigned to other fauclty to help them complete the research that they initiated under Dr. Tyner. His death was a tremendous loss to nationally focused research on biofuelds and related natural resource policy. How have the results been disseminated to communities of interest? Nothing Reported What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? The focus on Dr. Tyner's research waas biofuels and land use policy. He also contributed to work on the impacts of establishing rural broadband connectivity in Indiana. He reported that broadband would be especially beneficial to imporved health care in rural Indiana.
