How big is the distributed energy opportunity for water and wastewater utilities?
Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of annual ...

Investigation of the characteristics of the reflectivity of clouds
This paper investigates some of the reflectivity characteristics that clouds (when modelled as solid bodies) must exhibit to be compatible with observations that the reflecting surface of a cloud (i) appears almost equally bright across its face, (ii) is brightest when the cloud is opposite to the Sun but decreases in brightness as the cloud moves to other positions and (iii) increases in ...

Decentralised operation of residential energy resources in the smart grid
In the future smart grid, improvement of power system economic cost effectiveness by suitable integration of distributed energy resources (DERs) is a critical challenge. An agent–based framework is proposed in this paper for developing suitable control strategies for operations of four different types of residential–level DERs, which are storage devices, photo voltaic systems, and two ...

Distributed energy will play a key role in Renewable Energy Zones. Here’s how.
With the continued stream of announcements around the early closure of coal-fired power plants across Australia, Renewable Energy Zones (REZs) are a key way forward as coal makes its exit. To date, there are 41 potential REZs flagged for potential development, each undergoing different phases of planning and consultation. According to a recent EnergyCo event, New South Wales has less than ...

Benchmarking as a strategic policy tool for energy management
In this paper, we analyse to what extent benchmarking is a valuable tool in strategic energy policy analysis. First, the theory on benchmarking is concisely presented, e.g., by discussing the benchmark wheel and the benchmark path. Next, some results of surveys among business firms are presented. To offer a more detailed analysis of the scope and potential of benchmarking, results are presented ...

China's spatial-temporal pattern of population and energy
Irregular development among regions is one of the fundamental realities of China, especially in social and economic progress. Moreover, there is no exception in the development of population and energy. In this paper, we explore the characteristics of the seven most prominent patterns of regional population?energy development distribution. Furthermore, analysis is made of problems associated with ...

A consolidated economic model based on a new concept of biased equilibrium
The fundamental theorems of welfare economics are not designed to represent the real world. Instead, they tell us about certain conditions under which general equilibrium will be efficient. This paper introduces a new concept 'biased equilibrium' based on information economics and consolidates neoclassical economics and institutional economics together. In the real world economy, the probability ...

4 Insights on Unlocking Finance for Clean Energy Access in Africa
January heralds the start of not just a new year, but a new decade: the U.N. Decade of Sustainable Energy for All. In declaring the Decade, the U.N. has urged its members to help “make universal access to sustainable modern energy services a priority.” One of the regions where universal access to clean energy remains a pressing challenge is sub-Saharan Africa, where roughly 590 ...

When Disaster Response Drives Transformational Change to Grids, Fuel Cells are the Preferred Choice of Many Energy Prosumers
The increasing frequency of weather-related disasters puts emergency disaster response in the headlines often and encourages more and more systematic solutions. In the example of wildfires in the U.S., where 30,000 fires burned over 3.5 million acres between January – August 2019, systematic solutions are crucial. Seeking to minimize fire damage, utilities in California have instilled the ...

On the probabilistic distribution of wind speeds: theoretical development and comparison with data
The probabilistic distributions of wind speed are a critical piece of information needed in the assessment of wind-energy potential, and have been conventionally described by various empirical correlations. Among the empirical correlations, the Weibull distribution has been most popular due to its ability to fit most accurately the variety of wind-speed data measured at different geographical ...

Why it is so Hard – and so Important – To increase distributed resources
If distributed resources are such a good idea, why don’t we build more of them? A report released this week by Tufts University sheds some light on the answer. Despite all of the talk about the efficiency they bring to the grid, resources like solar energy and combined heat and power still face significant regulatory and monetary hurdles. Consider the following findings from ...

Integrated framework for energy loss allocation in electric distribution systems under liberalised energy markets
This paper discusses an integrated framework for cost allocation of energy losses of electric distribution systems under liberalised energy markets. As key contribution is developed an allocation strategy based upon Locational and Uniform Incremental Prices. The locational incremental prices send efficient economical signals to distributed generators with incentives for loss minimisation and ...
