Jet streams are regions of sustained high wind speeds in the upper atmosphere and are seen by some as a substantial renewable energy resource. However, jet streams are nearly geostrophic flow, that is, they result from the balance between the pressure gradient and Coriolis force in the near absence of friction. Therefore, jet stream motion is associated with very small generation rates of kinet...

Greenhouse gas mitigation efforts in the electricity sector emphasize accelerated deployment of energy efficiency measures and renewable energy resources. We evaluate renewable energy (RE) and energy efficiency (EE) technologies across regional power systems in the United States in terms of carbon dioxide emissions displaced, operating costs avoided, and capacity value generated. We estimate th...

The European Union (EU) energy policy has three targets: supply security, development of a competitive energy sector and environmental sustainability. The EU countries have issued so-called National Renewable Energy Action Plans (NREAP) for increased renewable energy generation. Biomass is stipulated to account for 56% of renewable energy generation by 2020, corresponding to an increase in bioe...

emerging technologies increase the needs on self efficient mobile robotic applications that bring a new concern of sustainable and continuous power supply for the robotic platforms. this paper covers the various techniques and technologies used to design a solar powered robot, exploring the currently available products, software and limitations to this application. the main aim is to integrate ...

A model is presented in this work for simulating endogenously the evolution of the marginal costs of production of energy carriers from non-renewable resources, their consumption, depletion pathways and timescales. Such marginal costs can be used to simulate the long term average price formation of energy commodities. Drawing on previous work where a global database of energy resource economic ...

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...

Cities are increasingly challenged in sustaining their growing populations with food. As fossil energy reserves are depleted, the sustainability of food production is highly dependent on the ability to yield more food relative to resource use. In preparing cities for peak oil, urban food systems are therefore needed that make better use of local and renewable resources, as opposed to imported a...

Renewable energy now-a-days is playing vital role in energy demand market and solar and wind are most wanted renewable energy resources to support the enormous power demand across the globe. Due to insufficient wind for more than half of the year, wind turbines are not capable of meeting the power demand. Hence, solar is treated as the main energy resource among all the renewable energy resourc...
