  • 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 ...

  • It’s time to invest in clean energy in Africa

    Private-sector investment in electricity is sitting on the sidelines in Africa. Here’s how we can change that. The math for Africa’s clean energy future is adding up. Solar lamps are spreading like fireflies across Ghana. A first-of-its-kind solar farm in Rwanda is providing electricity for 15,000 rural homes. Utility-scale solar and wind projects are being built in ...

  • Water distribution network robust design based on energy surplus index maximization

    The aim of this paper is to show that energy surplus indices, such as resilience index, besides providing a very good indirect measure of water distribution network reliability, also represent a valuable and effective indicator of network robustness under alternative network scenarios. It can thus be profitably used for network design under conditions of uncertain future demands. The ...

  • How do you bring electricity to 620 million people?

    Sub-Saharan Africa needs a more reliable energy supply. The way it chooses to meet that need will affect the entire planet. In South Africa, major cities are subject to regular power outages as electric utility Eskom periodically shuts down parts of its distribution system to take the pressure off the aging national grid. Whole areas of Cape Town and Johannesburg are without power ...

  • Cascade failures and distributed generation in power grids

    Power grids are nowadays experiencing a transformation due to the introduction of distributed generation based on renewable sources. At difference with classical distributed generation, where local power sources mitigate anomalous user consumption peaks, renewable sources introduce in the grid intrinsically erratic power inputs. By introducing a simple schematic (but realistic) model for power ...

  • Debbie Dooley: Making the Tea Party — and America — a little greener

    When you think of the Tea Party, the first thing that comes to mind probably isn’t renewable energy. Debbie Dooley, national coordinator of the Tea Party Patriots and founder of the Green Tea Coalition, is out ...

  • Reinvent the toilet: the NUS experience of building a decentralized toilet for energy, water and resource recovery

    In conventional activated sludge (CAS) treatment of sewage, the pollutants are mostly dissipated and hardly any reuse is present. This makes wastewater treatment very energy intensive and not sustainable in the future. Instead, sewage should be considered as a renewable resource, from which value can be extracted in the form of water, energy and nutrients (mostly nitrogen, N, phosphorus, P and ...

  • Opportunities and obstacles: integrating energy efficiency into the transmission and distribution planning process

    This paper seeks to highlight issues that warrant further evaluation associated with more precisely incorporating energy efficiency (EE) into a utility's system wide transmission and distribution (T&D) plan from a financial and load forecasting perspective while accounting for system reliability and ratepayer concerns. This paper also analyses how EE is integrated into grid operators' ...

  • Optimal location of DG for maintaining distribution system stability: a hybrid technique

    To enhance the distribution power quality and maintains the voltage stability is a challenging tasks in the complex distribution network. This can be achieved through the distributed generation (DG). In this paper, a hybrid technique has been proposed which improves the distribution stability by allocating the DG at the optimal place. This technique uses the artificial neural network (ANN) and ...

  • A comprehensive analysis of natural gas distribution pipeline incidents

    The objective of this paper is to provide a reference database for pipeline companies and/or regulators with an investigation of safety performance of US natural gas distribution pipelines. With a total of 3,679 natural gas distribution pipeline incidents between 1985 and 2010, nine safety indicators are statistically analysed in terms of the year, pipeline length, regions, pipeline diameter, ...

  • Distributed generation planning in deregulated power market - a bibliographical survey

    As a result of deregulation, increased use of dispersed generation requires revisiting in management and operation of distribution network. Selection of optimal network topology incorporated with the optimal use of dispersed generation and retail market including real and reactive power. Minimisation of related costs and satisfying technical and physical constraints is also the key issue to ...

  • Effect of distributed generation modelling on performance of distribution systems

    Due to the continuous increase of distributed generation (DG) penetration into distribution systems, load flow analysis always needs improvement to be more flexible, fast and computationally efficient especially when integrating DG with existing distribution systems. The work in this paper is divided into two parts; in the first part a new algorithm is developed to solve the power flow problem ...

  • Between field and table: environmental implications of local food distribution

    Local food has been championed as a sustainable alternative to the industrial food system for many reasons, including a perceived environmental benefit through an expected decrease in the energy needed for transport from farm to market. The environmental benefit of local food, however, has been clouded by questions surrounding the energy footprint of small–scale distribution methods that do ...

  • Environmental tax reform in Europe: implications for income distribution

    Key messages - Although ETRs tend to improve incomes across society, they can have mild regressive impacts in that richer households gain more than poorer ones. - Care is needed to design ETRs in ways that ensure that certain groups are able to benefit equally. - ETR's overall benefits for the economy, environment and society are potentially ...

  • The shifting landscape for renewable energy in the UK

    The UK Government has a commitment to reduce the UK’s greenhouse gas emissions by at least 80 percent by 2050 (from 1990 levels). As a result, the UK landscape surrounding renewable energy is shifting rapidly to help deliver a low carbon future. Recently, there have been a number of national consultations which are likely to have a significant bearing on the future viability of non-fossil ...

  • Unpacking the energy implications of distributed water infrastructure: how are rainwater systems performing?

    Drought and concern over climate change has led to the increased use of distributed water systems in Australia to supplement centralised supply systems. A literature review carried out by the Institute for Sustainable Futures (ISF) into the energy consumption of water infrastructure found that very little data on energy consumption exists, particularly for distributed systems. This paper reviews ...
