Energy efficiency and renewable energy are the main pillars of sustainability and environmental compatibility. This study presents an overview of sustainable and green cellular base stations (BSs), which account for most of the energy consumed in cellular networks. We review the architecture of the BS and the power consumption model, and then summarize the trends in green cellular network resea...

The ability of renewable resources to provide all of society's energy needs is shown by using the United States as an example. Various renewable systems are presented, and the issues of energy payback, carbon dioxide abatement, and energy storage are addressed. Pathways for renewable hydrogen generation are shown, and the implementation of hydrogen technologies into the energy infrastructure is...

To reduce the GHG emissions of IP over WDM networks, we introduce renewable energy usage at each network node and design the networks considering the state of renewable energy available at each node location. Results indicate that the designed network can save up to 50% or more non-renewable energy consumption in the example scenarios considered here compared with the design method which simply...

abstract i n this paper we investigated total energy consumption and its individual forms (oil, natural gas, electricity, renewable energies and coal) relationship with real gross domestic product (gdp) in iran. we employed hsiao’s (1981) methodology and annual data which cover 1967-2010 for investigation. the empirical findings indicate there is bidirectional causality effect with real gdp and...

Today, renewable energy source of power generation has become very promising. As we know that conventional or non-renewable source of energies are very limited and are depleting very rapidly. Increasing energy needs of the world and continually growing population there is a power demand gap and it needs alternate sources of energy. So, there is a view to generate more and more power from renewa...

The increasing use of high shares renewable energy sources (RESs) in the current electricity network introduces challenges to design and management due variation uncertainty nature RESs. Some existing infrastructures, such as heat, gas, transport, all have some level inbuilt storage capacity demand response (DR) potentials that can be exploited an system integration give flexibility promote eff...
