This paper analyzes dynamic economies in renewable energy technologies. The paper has two contributions. The first is to test the robustness of experience in solar photovoltaic, solar thermal and wind energy to the addition of an explicit time trend, which has been done in experience studies for other industries, but not for renewable energy technologies. Estimation is carried out on the assump...

This article discusses the prospects for the development of the implementation of scientific and technical cooperation. On the example of international cooperation between Ukraine and Chile, there are approaches to improving the procedure for developing cooperation priorities. The current state of these relations does not reflect real trends in the development of international economic relation...

Introduction Improvement of the energy industry in developing countries is the major basis of the process of techno-economic and socio-cultural development. This improvement requires the transfer of energy technology which is dominated by non-renewable energy systems. Natural resources which are mostly non-renewable, on the other hand, face various threats caused by such a process of developmen...

Concerns about depletion of fossil fuels and energy security have increased interest in renewable energy sources. Biogas, generated from anaerobic digestion of organic wastes, has a relatively low cost and is considered to be a renewable energy carrier. There is an increasing interest in converting biogas to “green” transportation fuels. This fact sheet discusses the technologies that are curre...

Energy technologies and innovation are considered to play a crucial role in climate change mitigation. Yet, the representation of technologies in energy-economy models, which are used extensively to analyze the economic, energy and environmental impacts of alternative energy and climate policies, is rather limited. This dissertation presents advanced techniques of including technological innova...

The electricity and potable water production sector in Kuwait depends solely on oil and gas fired generation technologies. Complete reliance on oil and gas has negative impact on the country's economy and environment, and hence, calls for exploration for alternative energy sources. This paper presents results of analysis of including renewable energy technologies within the generation inventory...

Biomass represents an abundant carbon-neutral renewable resource for the production of bioenergy and biomaterials, and its enhanced use would address several societal needs. Advances in genetics, biotechnology, process chemistry, and engineering are leading to a new manufacturing concept for converting renewable biomass to valuable fuels and products, generally referred to as the biorefinery. T...
