Renewable energy can help to tackle energy poverty issues of the availability of modern energy services and the sustainability of energy supply. Based on the concept of the Energy Development Index, published by International Energy Agency, this paper builds the clean energy development index and applies the Grey incidence decision method to analyze regional energy poverty issues in China. A mo...

The next-generation energy network, the so-called smart grid (SG), promises a tremendous increase in efficiency, safety and flexibility of managing the electricity grid as compared to the legacy energy network. This is needed today more than ever as the global energy consumption is growing at an unprecedented rate, and renewable energy sources have to be seamlessly integrated into the grid to a...

We study the optimal transition from fossil fuels to renewable energy in a neoclassical growth economy with endogenous technological progress in energy production. Technological innovations maintain a fairly constant cost of fossil fuel energy even as increased exploitation raises mining costs. Nevertheless, the economy transitions to renewable energy once energy costs escalate after about 80% ...

1. introduction the concept of sustainable travel and transport is embedded in the broader concept of sustainable development, which relates to maintaining or improving the quality of human life and variety of social opportunities within the natural constraints and limits of the global ecosystem. the organization for economic cooperation and development (2004) defines an environmentally sustain...

The salinity difference between seawater and river water is a renewable source of enormous entropic energy, but extracting it efficiently as a form of useful energy remains a challenge. Here we demonstrate a device called "mixing entropy battery", which can extract and store it as useful electrochemical energy. The battery, containing a Na(2-x)Mn(5)O(10) nanorod electrode, was shown to extract ...

nowadays energy has significant role in socio economic development of counties; any decision on energy sector may affect the broad area in societies. system approach in energy modeling as an efficient method is known by many researchers in management and planning in a country particularly in energy sector. also system dynamics is one of the efficient methods, for reason unique ability at solvin...
