In December 2015 the nations of the world agreed, in principle, to limit global warming to no more than 2 ◦C above pre-industrial levels. In order to achieve this goal, recent publications have shown that (1) more than 50% of known fossil fuel reserves need to remain unused, and (2) the timing of the transition away from fossil fuels needs to achieve 50% renewable energy by 2028, an expansion o...

The extraction of energy from renewable sources is rapidly growing. The current pace of technological development makes it commercially viable to harness energy from sun, wind, geothermal and many other renewable sources. Because of the negative effects on the environment and the economy, conventional energy sources like natural gas, crude oil and coal are coming under political and economic pr...

An overview of research activity in the area of powering base station sites by means of renewable energy sources is given. It is shown that mobile network operators express significant interest for powering remote base stations using renewable energy sources. This is because a significant percentage of remote base station sites on the global level are still diesel powered due to lack of connect...

As people living in remote areas rely on SPS systems for their electricity and water needs, they hold a practical and non-idealistic perspective towards using renewable energy technologies. This research explores pastoral owner-operators’ personal experience and opinion of stand-alone power supply (SPS) systems over 30 years in remote pastoral regions Western Australia (WA). This research was u...

Power consumption in IP-over-WDM networks has become a major concern, more so due to rapidly evolving data intensive applications. Increasing power consumption also increases the environmental cost (carbon emission). Carbon emissions are the result of power generation using non-renewable (traditional hydrocarbons) energy resources. Usage of non-renewable energy resources (such as hydrocarbons, ...

Policies to promote renewable energy have been gaining momentum throughout the world, often justified by environmental and energy security concerns. This paper delves into the economic motivation for renewable energy policies by articulating the classes of market failures relevant to renewable energy. We describe how these market failures may vary atemporally or intertemporally, and why the tem...

China’s 2020 Renewable Portfolio Standards (RPS) target has been published by the government in early 2016. In the present study, in order to find its implementation pathways and estimate the key impacts of PRS target out to 2030, a multi-region power market model is proposed to investigate different RPS policy scenarios. Results show that RPS policy can promote the development of renewable ene...
