Appropriate green technologies are sometimes regarded as a second-rate solution but the series Innovations for a Sustainable World challenges this concept by presenting real-life examples of successful appropriate technological stories from Europe, Asia, Africa and Latin America. All of the studies in these two books have been produced as a result of personal experience from somewhere in the world. Subjects covered in the series include success stories from agriculture, agro-processing, enterprise, energy, building and shelter, water and sanitation and recycling. Based on the Hands On series of video films prepared by the Television Trust for the Environment and broadcast on BBC World, these books promote appropriate innovations and environmentally sound solutions which can help reduce consumption. All of the new technologies and scientific breakthroughs described in the books can be applied by individuals and entrepreneurs at a reasonable cost to themselves and to the community. Some of the initiatives can be applied in the home, while others can be used by entrepreneurs to stimulate green business and small-scale enterprise. The books offer a range of suitable solutions for development professionals, NGOs, entrepreneurs and individuals who want to improve peoples livelihoods and the environment. They give practical advice and demonstrate a wide range of how to technologies including income-generating schemes in cities like Delhi and Dhaka, transport initiatives in Kathmandu and Copenhagen, and energy-saving projects in Addis Ababe and Beijing. Hands On - Energy, Infrastructure and Recycling covers innovations in energy and power, buildings, transport and re-use of materials.

Solar energy utilisation is the most important energy resource for bridging the gap between demand and supply of various energy needs in urban and peri-urban areas. The energy consumption is basically in terms of electricity for many appliances and equipment in homes, thermal energy for heating and cooling in homes and passive solar architecture for energy efficient buildings. On the other hand, the conventional energy consumption also induces the ecological imbalance such as the generation of greenhouse gases. Therefore solar energy may be considered an environmentally friendly alternative energy source for sustainable development. In this chapter, different active and passive solar energy harnessing techniques have been discussed, analysed and recommended leading to zero energy buildings (ZEBs) in urban and peri-urban areas. Here the study of solar energy applications for all types of energy needs in a residential building for advanced, ecological and smart liveability is presented. In this Chapter, we suggest some effective ways to harvest solar energy in urban and peri-urban areas using active and passive solar techniques.

Hydropower and thermoelectric power together contribute 98% of the world’s electricity generation at present. These power-generating technologies both strongly depend on water availability, and water temperature for cooling also plays a critical role for thermoelectric power generation. Climate change and resulting changes in water resources will therefore affect power generation while energy demands continue to increase with economic development and a growing world population. Here we present a global assessment of the vulnerability of the world’s current hydropower and thermoelectric power-generation system to changing climate and water resources, and test adaptation options for sustainable water–energy security during the twenty-first century. Using a coupled hydrological–electricity modelling framework with data on 24,515 hydropower and 1,427 thermoelectric power plants, we show reductions in usable capacity for 61–74% of the hydropower plants and 81–86% of the thermoelectric power plants worldwide for 2040–2069. However, adaptation options such as increased plant efficiencies, replacement of cooling system types and fuel switches are effective alternatives to reduce the assessed vulnerability to changing climate and freshwater resources. Transitions in the electricity sector with a stronger focus on adaptation, in addition to mitigation, are thus highly recommended to sustain water–energy security in the coming decades.

Recent droughts and heatwaves showed the vulnerability of the electricity sector to surface water constraints with reduced potentials for thermoelectric power and hydropower generation in different regions. Here we use a global hydrological-electricity modelling framework to quantify the impacts of recent drought and warm years on hydropower and thermoelectric power usable capacity worldwide. Our coupled modelling framework consists of a hydrological model, stream temperature model, hydropower and thermoelectric power models, and was applied with data of a large selection of hydropower and thermoelectric power plants worldwide. Our results show that hydropower utilisation rates were on average reduced by 5.2% and thermoelectric power by 3.8% during the drought years compared to the long-term average for 1981–2010. Statistically significant (p < 0.01) impacts on both hydropower and thermoelectric power usable capacity were found during major drought years, e.g. 2003 in Europe (-6.6% in hydropower and -4.7% in thermoelectric power) and 2007 in Eastern North America (-6.1% in hydropower and -9.0% in thermoelectric power). Our hydrological-electricity modelling framework has potential for studying the linkages between water and electricity supply under climate variability and change, contributing to the quantification of the 'water-energy nexus'.

ORC based power generation is becoming popular as a way of generating electricity from low-grade heat sources such waste heat. Working fluid selection and system optimization based on heat source temperature are two critical aspects of ORC design. In this work, eleven fluids comprised of hydrocarbons and refrigerants were theoretically investigated to maximize the work output for a range of source temperatures. Results show that Heptane, Pentane and Decane show favourable results in terms of work outputs while, in terms of efficiency, Decane and Heptane are better. Further, it was found that Pentane outperforms, when source temperatures are between 45 – 190 0C, while Heptane for 190 – 260 0C. Decane is more suitable for 260 – 340 0C range. Based on the theoretical analysis, a new summarized graphical chart was developed for Pentane, Heptane and Decane, where one point on the graph can denote approximate work output, efficiency, pressure, temperature and other required data for the initial design process and fluid selection of an ORC plant. Subsequently, the economic feasibility of ORC was assessed considering WH data of all the thermal plants of in Sri Lanka. Possible electric power outputs were computed for each selected plant, for selected fluids from the above theoretical analysis. Then, maximum work out of each case was selected for further economic evaluation under seven different scenarios, which represents the future economic situation in the country. Investment cost was estimated pertaining to the maximum work output and payback time was estimated to evaluate the investment feasibility. Interestingly, results show that some of the high volume power stations are very good candidate for ORC, which has very short payback time even with the worst possible economic situations considered.

In recent decades, academia has elaborated a wide range of technological solutions to recover water, energy, fertiliser and other products from municipal wastewater treatment plants. Drivers for this work range from low resource recovery potential and cost effectiveness, to the high energy demands and large environmental footprints of current treatment-plant designs. However, only a few technologies have been implemented and a shift from wastewater treatment plants towards water resource facilities still seems far away. This critical review aims to inform decision-makers in water management utilities about the vast technical possibilities and market supply potentials, as well as the bottlenecks, related to the design or redesign of a municipal wastewater treatment process from a resource recovery perspective. Information and data have been extracted from literature to provide a holistic overview of this growing research field. First, reviewed data is used to calculate the potential of 11 resources recoverable from municipal wastewater treatment plants to supply national resource consumption. Depending on the resource, the supply potential may vary greatly. Second, resource recovery technologies investigated in academia are reviewed comprehensively and critically. The third section of the review identifies nine non-technical bottlenecks mentioned in literature that have to be overcome to successfully implement these technologies into wastewater treatment process designs. The bottlenecks are related to economics and value chain development, environment and health, and society and policy issues. Considering market potentials, technological innovations, and addressing potential bottlenecks early in the planning and process design phase, may facilitate the design and integration of water resource facilities and contribute to more circular urban water management practices.
