A Solar Powered Computer Lab for Malawi
Project Background
Since 2013 The Turing Trust has been delivering computers to several sub-Saharan African countries for ICT skills training in schools and colleges, initially to Ghana and then spreading to Liberia and Malawi. The Trust was established by James Turing, an Edinburgh University student and great-nephew of Alan Turing, the code breaker and computational pioneer. Donated computers are securely disk-wiped, refurbished, and reloaded with software, then transported in shipping containers along with other IT equipment. Together with partner organisations in those countries, teachers are trained and supported in maintaining and using the equipment. Because many remote areas do not have a grid electricity supply, there was a need to provide much more than computers alone: the answer was to design a solar-powered computer laboratory, the “SolarBerry”.
A Real Look at Change Management for Utility Technology Implementation
Abstract
A wealth of literature exists on the need for change management in technology implementations and how deliberate the process needs to be for electric utilities to achieve successful and sustained business and technology transformation. Yet, there is little information available on the challenges a change management team will encounter within a utility's unique organizational structure. Many legacy barriers exist that need to be overcome for technology integrations to be successful.
This article presents a case study of how change management is successfully implemented for large technology upgrades, with best practices and insights from several other similar change management programs embedded in the case study. Like most change management initiatives, the case study provides an insider’s view of how the team engages various departments in the utility, and how change management professionals increase employee knowledge of the utility’s overall technology ecosystem prior to training on any new system implementations.
The role of flywheel energy storage in decarbonised electrical power systems
Flywheel technology has the potential to be a key part of our Energy Storage needs, writes Prof. Keith Robert Pullen:
Electricity power systems are going through a major transition away from centralised fossil and nuclear based generation towards renewables, driven mainly by substantial cost reductions in solar PV and wind. This transition, accelerated by government subsidies, has reached a self-sustaining momentum which will only accelerate as markets are reformed to be more consistent with this new order. Intermittency in demand has always been present short duration events were balanced passively by virtue of the rotating inertia of steam turbines and generators of large fossil and nuclear stations. Anything more than 10s of seconds required starting or peaking stations and/or pumped hydro storage. With the replacement of large stations, the supply is now intermittent and the stabilising inherent inertia is steadily being removed.
Compressed air energy storage – A new heat-integration, liquid-compression approach
Energy storage technologies can play a significant role in the difficult task of storing electrical energy writes Professor Christos Markides and Ray Sacks:
Compression energy in CAES systems
Energy storage is an important element in the efficient utilisation of renewable energy sources and in the penetration of renewable energy into electricity grids. Compressed air energy storage (CAES), amongst the various energy storage technologies which have been proposed, can play a significant role in the difficult task of storing electrical energy affordably at large scales and over long time periods (relative, say, to most battery technologies). CAES is in many ways like pumped hydroelectric storage (PHS), which has the largest worldwide installed capacity, quoted as 130 GW by Perez-Diaz et al. (2015) . In PHS, water is pumped to an elevated storage reservoir when excess electricity is available, and then allowed to flow downwards by gravity and through turbine generators when electrical power is required. For very large power capacities, PHS requires large natural-land features to hold the water, whereas CAES requires large underground sealable caverns which can hold high-pressure air.
Optimizing Natural Gas Generation with Energy Storage: A Gamechanger for the Transition to a Cleaner and More Affordable Power Sector
Janice Lin explains that renewables capacity will continue to grow at a rapid rate, and Energy Storage along with it:
The 21st-century grid is transforming faster than anyone imagined ten years ago, when natural gas seemed to be our power source of the future. Today, with ever-dropping prices in renewables and storage, the future is being re-defined.
A decade ago, the advent of horizontal drilling made natural gas the darling of the U.S. power sector, and for many good reasons. Natural gas lends itself to providing both steady baseload and easily dispatchable peak load power. Inexpensive, domestically produced and significantly lower in emissions than coal, natural gas was lauded as an abundant, cost-effective vehicle for enabling the lengthy transition to a renewables future that the domestic power sector faced. However, it now appears that the transition is happening much sooner than anticipated. As the deployment of renewables plus energy storage accelerates exponentially across the country, utilities are recognizing the proven ability of storage resources to supplement and, in some cases, completely replace gas-fired generation.
Central America's Energy Transition
Central American economic pressure limits exposure to fossil fuel imports, writes Christian Roselund:
When considering the places that have embraced renewable energy, one typically thinks of affluent, highly developed regions, such as Denmark, Germany, or California. However, the transition from conventional power to wind, solar, biomass and other forms of renewable energy is happening around the world1.
A region that is frequently overlooked is Central America. While Costa Rica’s achievement of procuring 98-99% of its electricity from renewables on an annual basis is widely celebrated, Nicaragua and Honduras have also been among the global leaders in the use of wind and solar to satisfy their electricity demand.And while each of these three nations has its own trajectory, together they can provide lessons for other regions.
Human electricity – a solution?
Substitute diesel with humans, then the power station would need to pay the humans weekly 0.77 the price of one lt of diesel:
The ruler of a hypothetical small island faces two very serious problems. The inhabitants of the country are unemployed and at the same time, the island's power station, using diesel generators, has to import diesel at a price of £1.2 per litre. Thus, the ruler comes up with a plan. He wants the population to work as a labour force in order to produce electricity through high efficiency hand crank dynamos and stop importing diesel altogether, killing two birds with one stone. Is this a plan worth doing?
Sensing Domestic Energy Use
It's important to improve Energy Efficiency. In the UK in 2016, for example, domestic energy use was second only to energy used for transportation, writes Brian Davison:
Most countries in the world recognise the threats associated with global warming, and have committed to binding targets to reduce their greenhouse gas emissions. In very general terms, there are two parts to a solution: cleaner energy which does not produce emissions in the first place, and reductions in energy demand so that any remaining emissions are minimised. The former is more exciting in many ways since it involves the development of new technologies, stand-offs between fossil fuel companies and environmentalists and a great deal of political wrangling. The latter in contrast is much more staid, and often comes down to tightening construction regulations and improving the fabric of existing buildings. A quick look at official statistics however demonstrates the importance of improving energy efficiency. In the UK in 2016, for example, domestic energy use was second only to energy used for transportation (Figure 1).
The Age of the Electric Car?
In this article we explore what is an Electric Vehicle (EV), how owning an EV may differ from our current conventionally fuelled personal passenger cars, and what we should expect in an age of the electric car.
Introduction
In 2016, worldwide stock of electric vehicles (EV) rose over 2 million, currently with 750,000 sales in that year alone (IEA 2016). Although varying across countries, Norway by far leads the world in electrifying its fleet with a 29% share of new registrations, due to a series of political efforts. Many countries have ambitious targets for EV market penetration, with China setting a target of 10% of sales by 2019 and 20% by 2025. Various other countries have proposals plans to phase out conventional vehicle sales including UK and France by 2040 and Norway by 2025. In the EU 1.5% of all new vehicle sales were electric in 2015. This is supported by a network of around 120,000 public charging points across Europe (EAFO 2017).
Flywheels: An economic and sustainable solution meeting the growing need for the electrical energy storage
Flywheels offer an attractive solution for fast response application, says Prof. Keith Robert Pullen:
Increasing penetration of renewables is creating supply and demand balancing problems across all timescales. This penetration, initially encouraged by government subsidies, is accelerating due to substantial cost reductions in solar voltaic and wind in particular. These balancing timescales range all the way from milliseconds affecting grid stability to hourly, daily and seasonal. Large coal fired steam engines possess stored energy in their rotating equipment which helps keep the AC frequency stable plus such engines could operate according to demand. Their removal from the system and replacement by renewable sources requires storage in order to maintain grid system stability and matching of supply and demand.
Heat Pumps For Decarbonizing the Building Sector
Heat pumps are the main devices to achieve the goal to decarbonize heating and cooling by using renewable sources:
Abstract
The building sector is responsible for about 40% of the total energy demand and 33% of the CO2 emissions. Until 2050 the building sector should become CO2 free. Measures are improving the building envelope, proper architecture and advanced heating and cooling systems, based on renewable energy sources.
In the case of new buildings a lot of standards and codes exist to minimize the energy consumption, at least for heating operation.
Project Finance, Energy Efficiency and Implications for Project Managers
The European Union has enhanced the quantity of public finances offered for efficiency schemes:
Featured Project Management article from Dr Yiannis Anagnostopolous from Kingston Business School
Within the last twenty years there has been a marked increasing and destabilising trend in energy prices with such trend forecasted to continue in the long-run. As an example, in the UK, gas and electricity prices have increased by over 80 per cent on average. According to DECC’s (Department of Energy and Climate Change, 2014) energy projections, electricity prices in the services sector are forecasted to increase by 66 per cent over and above inflation compared to the base of 2013 prices, whilst over the same period, gas prices are expected to increase by 31 per cent by 2030 (see Chart 1 below).
PV Systems at the Module Level
Support for module-level power electronics (MLPE) has grown recently in the U.S. Solar market in comparison with other solutions, writes Martin E. Herzfeld:
Abstract
"The continued growth of MLPE technology in PV arrays is influencing system design an installation practices."
Support for module-level power electronics (MLPE) has grown recently in the U.S. solar market in comparison with other solutions, such as traditional string inverters. There are not only new code requirements that promote MLPE solutions, but also design, installation and support considerations, including ongoing operations and maintenance (O&M). In addition, there are performance and availability factors that support the use of MLPE systems with practical safeguarding.
90% of Domestic Solar Generation Usable with Batteries
Over 1 million people across the country are living in houses powered by Solar Energy:
Opinion piece by leading authority in Solar Energy
Professor Susan Roaf
The citizens of Britain have been building the foundations for a sustainable solar future for two decades, under the radar, and against many odds, not least the barriers placed before them by many of the interested vested in Big Energy. UK now has over 8GW of installed PV energy of which around 2.3 GW is in domestic systems. The UK has only 9.4GW of installed nuclear capacity much of which is scheduled for cripplingly expensive decommissioning over the next decade or so. Solar energy is the People’s Power of choice: Safe, Clean and increasingly affordable for all.
C02 Refrigeration and Winery Operations
CO2 refrigeration systems not only easily replace existing systems, but they also offer a short payback period:
Operating a CO2 refrigeration system in a winery offers several benefits compared to traditional refrigeration technologies that utilize chlorofluorocarbons (CFC’s), hydro-chlorofluorocarbons (HCFC’s) and hydro-fluorocarbons (HFC’s). This article analyzes how winery owners and winemakers can benefit from lower costs and more efficient operational solutions that sustainable CO2 systems offer. CO2 refrigeration systems consume 20% less energy per year than existing systems and offer a total life-cycle cost savings of 25-35%.
Intelligent Buildings and Their Role in the Future Global Energy System
Research shows that by installing smart systems into buildings there can be large annual savings, says Jonathan Allcock:
Abstract
The global energy system is undergoing a massive change due to an overwhelming amount of evidence relating to climate change; in order to continue to reduce carbon emissions and increase overall energy efficiency, it is important to look at where and how the energy is consumed. Buildings are the largest energy consumer by sector and account for over one-third of global final energy consumption [1], it is important to recognise this because it shows a need for intelligent energy management within the building sector in order to decrease carbon emissions, increase building energy efficiency and energy security.
Energy Efficiency in Homes
The ability of a building to require low energy to provide comfort is the first of the two conditions required to reach the concept of a low energy building.
Interactive investigation of building energy performance
The work presents a methodology, based on a simulation model and graphical figures, for interactive investigations of building energy performance. The investigated examples illustrate how decisions in the early stages of the building design process can have decisive importance on final building energy performance in United States' (US) climates.
The behavioural modelling and simulation of PV modules under real weather conditions in PSPICE
Model the solar cells first and then to perform simulations, writes Chandrika Ramiah
Abstract
In this article the behavior of the solar cell with respect to solar irradiance has been studied. Solar cells have been modeled, simulated and analyzed through graphical interpretations. Three types of photovoltaic modules from different companies (50Wp monocrystalline, 50Wp polycrystalline and 50Wp amorphous silicon) have been modeled based on the one-diode model and their maximum power point has been simulated in PSpice AD. The performance of the solar modules has been evaluated in terms of their response variables namely short-circuit current, open-circuit voltage, maximum power point voltage and maximum power point current with respect to real weather data.
COP21 Global Climate Summit: A Review of the Paris Agreement
Prof. Sklar is an EEC Expert Lecturer of the Solar Photovoltaic and the Renewable Energy Management & Finance courses, organised jointly by the EEC Accredited Centre and The George Washington University. Prof. Sklar recently presented an inspiring TEDx Talk on the future of personal energy use.
The 21st Council of the Parties (COP21) ended in Paris as the first time in history where most of the countries in the world actually agreed to very public and somewhat ambitious actions to significantly reduce greenhouse gas emissions.
Non-Conventional Solar Energy Technologies
Solar parabolic troughs take advantage of the ability of a parabolic mirror to focus the sun’s rays at a specific focal point, writes George Loumakis:
Whenever the public hears about solar energy technologies, their mind revolves mostly around two specific applications. One of them is solar photovoltaics, also known as solar PV, and the other is solar thermal collectors. Solar PV produces DC electricity and has been predominantly used in domestic applications in the past – both standalone and grid connected – as well as a component in portable electronic appliance chargers, pocket calculators, and so on. Solar thermal collectors produce heat, either in the form of hot water or hot air, and are used for heating applications such as hot water heating or space heating. Both forms are very well established and have been around long enough so that they are now considered to be the norm in solar energy applications.

Introduction to OPVs and comparison with traditional PV technologies
Introduction
As populations outside of Europe and North America begin to enter the global middle class, one of the most notable effects of that transition will be a skyrocketing worldwide demand for electricity. This can already be observed in the worldwide trends in electricity consumption (Figure 1 [1]). In order to build this new growth on a sustainable foundation, much of this energy must come from renewable, nonpolluting sources.

A View on Hydropower Training
A View on Hydropower Training
by Prof. David Williams on behalf of
the British Hydropower Association
The continuing acceleration of global hydropower development provides a need for much more training in the subject, writes David Williams.
Introduction
The fight against climate change has brought global incentives for renewable energy resulting in the growth of new hydropower projects and refurbishment and upgrade of existing ones over the last decade.
With this increase in activity, the hydropower sector has grown rapidly in all types and size of projects. Equipment manufacturers, consultants, civil contractors, grid companies and other related activities have had to rapidly expand especially in manpower resource.
So why has there been an absence in mainstream training in hydropower in response to the growth in the industry?

Flexible solar cells formed directly on textiles have the capability for diverse applications:
Abstract
Present day photovoltaic (PV) modules are mostly rigid panels of standardised sizes that are not readily integrated into buildings or other large structures without compromising the architect’s design. Although thin-film solar cells have been available for many years, they are often based on metal or glass sheets and do not provide any adaptability in shape. We are developing thin-film solar cells that are fabricated directly on woven polyester fabric in an effort to address these limitations of conventional PV modules. After a brief explanation of how photovoltaic cells operate, we describe how the required layers are produced with plasma enhanced chemical vapour deposition (PECVD) and other coating technologies. Finally we envisage how the performance of these innovative renewable energy devices is anticipated to improve.

Global Warming: A key issue for refrigeration and air conditioning
Didier Coulomb
Director, International Institute of Refrigeration
Introduction
Refrigeration, including air conditioning, is necessary for life and will continue to expand worldwide. Its impact on environment is huge, even if refrigeration technologies can also be part of solutions for mitigating global warming (new sources of energy, heat pumps...). Many efforts have already been made. However, reduction in CO2 emissions and fluorinated gas emissions are challenges to be addressed on an ongoing basis.
Heat Pumps
Hermann Halozan
Institute of Thermal Engineering, Graz University of Technology
The potential for reducing CO2 emissions assuming a 30% share of heat pumps in the building sector using technology presently available is about 6% of the total world-wide CO2 emission.
1. INTRODUCTION
The old aim of governments was to supply their country with sufficient low-cost energy to keep the economy growing. But in the meantime we have some more problems: the one problem is that energy becomes more and more expensive, the second problem is climate change, and all industrialised countries, which have signed or not yet signed the Kyoto Agreement, have to reduce their greenhouse gas emissions, mainly CO2 from burning fossil fuels. Heat pumps offer the possibility of reducing energy consumption significantly, mainly in the building sector, but also in industry.
