| Summary/Abstract |
Photovoltaic (PV) Levelized Cost of Energy (LCOE) estimates are widely utilized by decision makers to predict the long-term cost and benefits of solar PV installations, but fail to consider local climate, which impacts PV panel lifetime and performance. Specific types of solar PV panels are known to respond to climate factors differently. Mono-, poly-, and amorphous-silicon (Si) PV technologies are known to exhibit varying degradation rates and instantaneous power losses as a function of operating temperature, humidity, thermal cycling, and panel soiling. We formulate an extended LCOE calculation, which considers PV module performance and lifespan as a function of local climate. The LCOE is then calculated for crystalline and amorphous Si PV technologies across several climates. Finally, we assess the impact of various policy incentives on reducing the firm's cost of solar deployment when controlling for climate. This assessment is the first to quantify tradeoffs between technologies, geographies, and policies in a unified manner. Results suggest crystalline Si solar panels as the most promising candidate for commercial-scale PV systems due to their low degradation rates compared to amorphous technologies. Across technologies, we note the strong ability of investment subsidies in removing uncertainty and reducing the LCOE, compared to production incentives.

| Summary/Abstract |
This paper explores the differences in technological priorities for decarbonization of the Russian and the European power sectors up to 2040 and investigates the main drivers of such differences. We used updated cost and performance data to conduct a comparative analysis of technologies based on levelized cost of electricity. Calculation of carbon avoided costs allowed us to found the pool of cost-efficient low-carbon technologies for the Russian power industry as well as the level of carbon prices needed to support their development. Also, we have explained the reasons which cause differences in decarbonization priorities in Russia and Europe. We have also investigated the impact of system requirements (and associated costs) in terms of capacity availability and its operating modes on the competitiveness of renewable energy sources and conventional power plants. Consideration of these requirements and costs improves the quality of power system planning and policy-making processes under the strict limits on greenhouse gas emissions. Based on performed analysis we suggest economically reasonable decarbonization strategy of the Russian power industry as well as the necessary level of carbon prices/taxes for various low- and non-carbon technologies to support their development.

| Summary/Abstract |
The Fukushima disaster has lead the French government to release novel cost information relative to its nuclear electricity program allowing us to compute a levelized cost. We identify a modest escalation of capital cost and a larger than expected operational cost. Under the best scenario, the cost of French nuclear power over the last four decades is View the MathML source (at 2010 prices) while in the worst case it is View the MathML source. On the basis of these findings, we estimate the future cost of nuclear power in France to be at least View the MathML source and possibly View the MathML source. A comparison with the US confirms that French nuclear electricity nevertheless remains cheaper. Comparisons with coal, natural gas and wind power are carried out to find the advantage of these.

| Summary/Abstract |
To date, most of the existing wind farms have been built on-land but during the last few years many countries have also invested in offshore applications. The shift towards offshore wind project developments has mainly been driven by European energy policies, especially in north-west countries. In offshore sites the winds are stronger and steadier than on-land, making wind farms more productive with higher capacity factors. On the other hand, although offshore wind energy is not in its infancy period, most of the costs associated with its development are still much higher from onshore counterparts; however some recent technological progress may have the potential to narrow this gap in the years to come. In the present work, an overview of the activity noted in the field of offshore wind energy is carried out, with emphasis being given on the current status and future trends of the technology employed, examining at the same time energy production and availability issues as well as economic considerations.

| Summary/Abstract |
Enhanced Geothermal Systems (EGS) could supply a significant fraction of the low-temperature (<125 °C) thermal energy used in the United States through Geothermal District Heating (GDH). In this study we develop a regional model to evaluate the potential for EGS district heating in the states of New York and Pennsylvania by simulating an EGS district heating network at each population center within the study region and estimating the levelized cost of heat (LCOH) from GDH for each community. LCOHs were then compiled into a supply curve from which several conclusions could be drawn.
Our evaluation revealed that EGS district heating has the potential to supply cost-effective energy for space and water heating in several New York and Pennsylvania communities in the near future. To realize wider deployment, modest improvements in EGS technology, escalation of natural gas prices, and/or government incentives will likely be required to enable GDH to compete with other heating alternatives today. EGS reservoir flow rates, drilling costs, system lifetimes, and fluid return temperatures have significant effects on the LCOH of GDH and thus will provide the highest return on R&D investment, while creative implementation strategies can help EGS district heating overcome initial cost barriers that exist today.
