This dissertation presents a set of analytical tools developed to investigate the energy system transition using a systems approach. The cases explored range from Kosovo, a country on the verge of new electricity supply investments, and future energy pathways to an analytical investigation of innovation in battery storage systems that could unlock the environmental and health benefits of intermittent renewable energy sources such as solar and wind technologies. The analytical tools compare existing metrics such as levelized cost of electricity with new metrics such as a two-factor learning curve of deployment and innovation and trace metal content of coal per final kWh of electricity delivered and energy return on investment of distributed energy systems.Chapter 1 investigates the case of Kosovo and introduces an analytic framework to analyze electricity costs and environmental impacts of future electricity options. The scheduled decommissioning of the Kosovo A coal-fired power plant provides an opportunity to investigate the changing cost of alternative energy options available in Kosovo for new energy infrastructure. I find that a range of investment pathways from international financial institutions and donor groups could meet the same projected electricity demand at a lower cost than building a new 600 MW coal fired power plant. The options include energy efficiency measures, combinations of solar PV, wind, hydropower, biomass, and the introduction of natural gas. The results indicate that financing a new coal plant is the most expensive pathway to meet future electricity demand in Kosovo.Chapter 2 utilizes the analytic framework developed to estimate the cost of future electricity pathways and uses green chemistry and public health risk assessment to estimate trace metal content of coal and investigate the air-pollution-related-health risks of lignite coal in Kosovo. By utilizing ICP-MS, I sample lignite coal for trace metal content and develop a risk model to

More than 6600 coal-fired power plants serve an estimated five billion people globally and contribute 46% of annual CO2 emissions. Gases and particulate matter from coal combustion are harmful to humans and often contain toxic trace metals. The decades-old Kosovo power stations, Europe's largest point source of air pollution, generate 98% of Kosovo's electricity and are due for replacement. Kosovo will rely on investment from external donors to replace these plants. Here, we examine non-CO2 emissions and health impacts by using inductively coupled plasma mass spectrometry (ICP-MS) to analyze trace metal content in lignite coal from Obilic, Kosovo. We find significant trace metal content normalized per kWh of final electricity delivered (As (22.3 ± 1.7), Cr (44.1 ± 3.5), Hg (0.08 ± 0.010), and Ni (19.7 ± 1.7) mg/kWhe). These metals pose health hazards that persist even with improved grid efficiency. We explore the air-pollution-related risk associated with several alternative energy development pathways. Our analysis estimates that Kosovo could avoid 2300 premature deaths by 2030 with investments in energy efficiency and solar PV backed up by natural gas. Energy policy decisions should account for all associated health risks, as should multilateral development banks before guaranteeing loans on new electricity projects.
