This paper describes the economically optimal adoption and operation of distributed energy resources (DER) by a hypothetical California microgrid (μGrid) consisting of a group of commercial buildings over an historical test year, 1999. The optimization is conducted using a customer adoption model developed at Berkeley Lab and implemented in the General Algebraic Modeling System. A μGrid is a semiautonomous grouping of electricity and heat loads interconnected with the existing utility grid (macrogrid) but able to island from it. The μGrid minimizes the cost of meeting its energy requirements (consisting of both electricity and heat loads) by optimizing the installation and operation of DER technologies while purchasing residual energy from the local combined natural gas and electricity utility. The available DER technologies are small-scale generators (<500 kW), such as reciprocating engines, microturbines, and fuel cells, with or without combined heat and power (CHP) equipment, such as water and space heating and/or absorption cooling. By introducing a tax on carbon emissions, it is shown that if the μGrid is allowed to install CHP-enabled DER technologies, its carbon emissions are mitigated more than without CHP, demonstrating the potential benefits of small-scale CHP technology for climate change mitigation. Reciprocating engines with heat recovery and/or absorption cooling tend to be attractive technologies for the mild southern California climate, but the carbon mitigation tends to be modest compared to purchasing utility electricity because of the predominance of relatively clean central station generation in California.

Distributed energy resources (DER) technologies, such as gas-fired reciprocating engines and microturbines, can be economically beneficial in meeting commercial-sector energy loads. Even with a lower electric-only efficiency than traditional central stations, combined heat and power (CHP) applications can increase overall system energy efficiency. From a policy perspective, it is useful to have good estimates of penetration rates of DER under different economic and regulatory scenarios. We model the diffusion of DER in the US commercial building sector under various technical research and technology outreach scenarios. Technology market diffusion is assumed to depend on the system's economic attractiveness and the developer's knowledge about the technology. To account for regional differences in energy markets and climates, as well as the economic potential for different building types, optimal DER systems are found for several building types and regions. Technology diffusion is predicted via a baseline and a program scenario, in which more research improves DER performance. The results depict a large and diverse market where the West region and office building may play a key role in DER adoption. With the market in an early stage, technology research and outreach programs may shift building energy consumption to a more efficient alternative.

In the last decade, many malaria-endemic countries, like Zambia, have achieved significant reductions in malaria incidence among children <5 years old but face ongoing challenges in achieving similar progress against malaria in older age groups. In parts of Zambia, changing climatic and environmental factors are among those suspectedly behind high malaria incidence. Changes and variations in these factors potentially interfere with intervention program effectiveness and alter the distribution and incidence patterns of malaria differentially between young children and the rest of the population. We used parametric and non-parametric statistics to model the effects of climatic and socio-demographic variables on age-specific malaria incidence vis-à-vis control interventions. Linear regressions, mixed models, and Mann-Kendall tests were implemented to explore trends, changes in trends, and regress malaria incidence against environmental and intervention variables. Our study shows that while climate parameters affect the whole population, their impacts are felt most by people aged ≥5 years. Climate variables influenced malaria substantially more than mosquito nets and indoor residual spraying interventions. We establish that climate parameters negatively impact malaria control efforts by exacerbating the transmission conditions via more conducive temperature and rainfall environments, which are augmented by cultural and socioeconomic exposure mechanisms. We argue that an intensified communications and education intervention strategy for behavioural change specifically targeted at ≥5 aged population where incidence rates are increasing, is urgently required and call for further malaria stratification among the ≥5 age groups in the routine collection, analysis and reporting of malaria mortality and incidence data.

An analysis was made of siting issues in the coastal zone, one of the nation's most critical natural resource areas and one which is often the target for energy development proposals. The analysis addressed the changing perceptions of citizens toward energy development in the coastal zone, emphasizing urban communities where access to the waterfront and revitalization of waterfront property are of interest to the citizen. The findings of this analysis are based on an examination of energy development along New Jersey's urban waterfront and along the Texas-Louisiana Gulf Coast, and on redevelopment efforts in Seattle, San Francisco, Boston, and elsewhere. The case studies demonstrate the significance of local attitudes and regional cooperation in the siting process. In highly urbanized areas, air quality has become a predominant concern among citizen groups and an influential factor in development of alternative energy facility siting strategies, such as consideration of inland siting connected by pipeline to a smaller coastal facility. The study addresses the economic impact of the permitting process on the desirability of energy facility investments, and the possible effects of the location selected for the facility on the permitting process and investment economics. The economic analysis demonstrates the importance of viewing energymore » facility investments in a broad perspective that includes the positive or negative impacts of various alternative siting patterns on the permitting process. Conclusions drawn from the studies regarding Federal, state, local, and corporate politics; regulatory, permitting, licensing, environmental assessment, and site selection are summarized.

The Lancet Countdown : le suivi des progrès en matière de santé et de changement climatique est une collaboration de recherche internationale et multidisciplinaire entre des établissements universitaires et des praticiens du monde entier. Il fait suite aux travaux de la Commission Lancet de 2015, qui a conclu que la réponse au changement climatique pourrait être « la plus grande opportunité de santé mondiale du XXIe siècle ». Le compte à rebours du Lancet vise à suivre les impacts sur la santé des risques climatiques ; la résilience et l'adaptation en matière de santé ; les co-bénéfices pour la santé de l'atténuation du changement climatique ; l'économie et la finance ; et l'engagement politique et plus large. Ces domaines d'intervention forment les cinq groupes de travail thématiques du Lancet Countdown et représentent différents aspects de l'association complexe entre la santé et le changement climatique. Ces groupes thématiques fourniront des indicateurs pour une vue d'ensemble mondiale de la santé et du changement climatique ; des études de cas nationales mettant en évidence les pays qui ouvrent la voie ou vont à l'encontre de la tendance ; et un engagement avec un éventail de parties prenantes. Le compte à rebours du Lancet vise finalement à rendre compte chaque année d'une série d'indicateurs dans ces cinq groupes de travail. Ce document décrit les indicateurs potentiels et les domaines d'indicateurs à suivre par la collaboration, avec des suggestions sur les méthodologies et les ensembles de données disponibles pour atteindre cet objectif. Les domaines d'indicateurs proposés doivent être affinés et marquent le début d'un processus de consultation en cours - de novembre 2016 au début de 2017 - pour développer ces domaines, identifier les domaines clés non couverts actuellement et modifier les indicateurs si nécessaire. Cette collaboration cherchera activement à s'engager dans les processus de suivi existants, tels que les objectifs de développement durable des Nations Unies et les profils de pays de l'OMS en matière de climat et de santé. Les indicateurs évolueront également au fil du temps grâce à une collaboration continue avec des experts et un éventail de parties prenantes, et dépendront de l'émergence de nouvelles preuves et connaissances. Au cours de ses travaux, le Lancet Countdown adoptera un processus collaboratif et itératif, qui vise à compléter les initiatives existantes, à accueillir l'engagement avec de nouveaux partenaires et à être ouvert au développement de nouveaux projets de recherche sur la santé et le changement climatique. The Lancet Countdown: tracking progress on health and climate change es una colaboración de investigación internacional y multidisciplinaria entre instituciones académicas y profesionales de todo el mundo. Sigue el trabajo de la Comisión Lancet de 2015, que concluyó que la respuesta al cambio climático podría ser "la mayor oportunidad de salud global del siglo XXI". The Lancet Countdown tiene como objetivo realizar un seguimiento de los impactos en la salud de los peligros climáticos; la resiliencia y la adaptación a la salud; los beneficios colaterales para la salud de la mitigación del cambio climático; la economía y las finanzas; y el compromiso político y más amplio. Estas áreas de enfoque forman los cinco grupos de trabajo temáticos de The Lancet Countdown y representan diferentes aspectos de la compleja asociación entre la salud y el cambio climático. Estos grupos temáticos proporcionarán indicadores para una visión global de la salud y el cambio climático; estudios de casos nacionales que destacan a los países que lideran el camino o van en contra de la tendencia; y el compromiso con una variedad de partes interesadas. En última instancia, The Lancet Countdown tiene como objetivo informar anualmente sobre una serie de indicadores en estos cinco grupos de trabajo. Este documento describe los posibles indicadores y dominios de indicadores a ser rastreados por la colaboración, con sugerencias sobre las metodologías y conjuntos de datos disponibles para lograr este fin. Los dominios de indicadores propuestos requieren un mayor refinamiento y marcan el comienzo de un proceso de consulta continuo, desde noviembre de 2016 hasta principios de 2017, para desarrollar estos dominios, identificar áreas clave que actualmente no están cubiertas y cambiar los indicadores cuando sea necesario. Esta colaboración buscará activamente involucrarse con los procesos de monitoreo existentes, como los Objetivos de Desarrollo Sostenible de la ONU y LOS perfiles climáticos y de salud de los países de la OMS. Los indicadores también evolucionarán con el tiempo a través de la colaboración continua con expertos y una variedad de partes interesadas, y dependerán de la aparición de nuevas pruebas y conocimientos. Durante el transcurso de su trabajo, The Lancet Countdown adoptará un proceso colaborativo e iterativo, que tiene como objetivo complementar las iniciativas existentes, dar la bienvenida al compromiso con nuevos socios y estar abierto al desarrollo de nuevos proyectos de investigación sobre salud y cambio climático. The Lancet Countdown: tracking progress on health and climate change is an international, multidisciplinary research collaboration between academic institutions and practitioners across the world. It follows on from the work of the 2015 Lancet Commission, which concluded that the response to climate change could be "the greatest global health opportunity of the 21st century". The Lancet Countdown aims to track the health impacts of climate hazards; health resilience and adaptation; health co-benefits of climate change mitigation; economics and finance; and political and broader engagement. These focus areas form the five thematic working groups of the Lancet Countdown and represent different aspects of the complex association between health and climate change. These thematic groups will provide indicators for a global overview of health and climate change; national case studies highlighting countries leading the way or going against the trend; and engagement with a range of stakeholders. The Lancet Countdown ultimately aims to report annually on a series of indicators across these five working groups. This paper outlines the potential indicators and indicator domains to be tracked by the collaboration, with suggestions on the methodologies and datasets available to achieve this end. The proposed indicator domains require further refinement, and mark the beginning of an ongoing consultation process-from November, 2016 to early 2017-to develop these domains, identify key areas not currently covered, and change indicators where necessary. This collaboration will actively seek to engage with existing monitoring processes, such as the UN Sustainable Development Goals and WHO's climate and health country profiles. The indicators will also evolve over time through ongoing collaboration with experts and a range of stakeholders, and be dependent on the emergence of new evidence and knowledge. During the course of its work, the Lancet Countdown will adopt a collaborative and iterative process, which aims to complement existing initiatives, welcome engagement with new partners, and be open to developing new research projects on health and climate change. العد التنازلي لمجلة لانسيت: تتبع التقدم المحرز في مجال الصحة وتغير المناخ هو تعاون بحثي دولي متعدد التخصصات بين المؤسسات الأكاديمية والممارسين في جميع أنحاء العالم. ويتبع ذلك عمل لجنة لانسيت لعام 2015، التي خلصت إلى أن الاستجابة لتغير المناخ يمكن أن تكون "أعظم فرصة صحية عالمية في القرن الحادي والعشرين". يهدف العد التنازلي لمجلة لانسيت إلى تتبع الآثار الصحية للمخاطر المناخية ؛ والمرونة الصحية والتكيف ؛ والفوائد الصحية المشتركة للتخفيف من آثار تغير المناخ ؛ والاقتصاد والتمويل ؛ والمشاركة السياسية والأوسع نطاقًا. تشكل مجالات التركيز هذه مجموعات العمل المواضيعية الخمسة للعد التنازلي لمجلة لانسيت وتمثل جوانب مختلفة من الارتباط المعقد بين الصحة وتغير المناخ. وستوفر هذه المجموعات المواضيعية مؤشرات لإلقاء نظرة عامة عالمية على الصحة وتغير المناخ ؛ ودراسات حالة وطنية تسلط الضوء على البلدان التي تقود الطريق أو تسير عكس الاتجاه ؛ والمشاركة مع مجموعة من أصحاب المصلحة. يهدف العد التنازلي لمجلة لانسيت في نهاية المطاف إلى تقديم تقرير سنوي عن سلسلة من المؤشرات عبر مجموعات العمل الخمس هذه. تحدد هذه الورقة المؤشرات المحتملة ومجالات المؤشرات التي سيتم تتبعها من خلال التعاون، مع اقتراحات حول المنهجيات ومجموعات البيانات المتاحة لتحقيق هذه الغاية. تتطلب مجالات المؤشرات المقترحة مزيدًا من التنقيح، وتمثل بداية عملية تشاور مستمرة - من نوفمبر 2016 إلى أوائل 2017 - لتطوير هذه المجالات، وتحديد المجالات الرئيسية غير المشمولة حاليًا، وتغيير المؤشرات عند الضرورة. سيسعى هذا التعاون بنشاط إلى المشاركة في عمليات الرصد القائمة، مثل أهداف الأمم المتحدة للتنمية المستدامة والملامح القطرية للمناخ والصحة لمنظمة الصحة العالمية. ستتطور المؤشرات أيضًا بمرور الوقت من خلال التعاون المستمر مع الخبراء ومجموعة من أصحاب المصلحة، وستعتمد على ظهور أدلة ومعارف جديدة. خلال عملها، سيعتمد العد التنازلي لمجلة لانسيت عملية تعاونية وتكرارية، تهدف إلى استكمال المبادرات الحالية، والترحيب بالمشاركة مع شركاء جدد، والانفتاح على تطوير مشاريع بحثية جديدة حول الصحة وتغير المناخ.

The findings of a literature review on the environmental concerns and associated control methods of geothermal energy utilization are presented. The document introduces the environmental problems associated with geothermal energy utilization; assesses the current status of control methods; references appropriate environmental documents; and identifies areas where additional environmental research is needed. The review attempts to consolidate current understanding of the environmental impact of geothermal energy development. Approximately 180 reports written by authors in industry, government and academia have been reviewed in the areas of air emissions, surface and subsurface liquid discharges, solid wastes, noise, subsidence, and induced seismicity.

AbstractThe role of climate change on global malaria is often highlighted in World Health Organisation reports. We modelled a Zambian socio-environmental dataset from 2000 to 2016, against malaria trends and investigated the relationship of near-term environmental change with malaria incidence using Bayesian spatio-temporal, and negative binomial mixed regression models. We introduced the diurnal temperature range (DTR) as an alternative environmental measure to the widely used mean temperature. We found substantial sub-national near-term variations and significant associations with malaria incidence-trends. Significant spatio-temporal shifts in DTR/environmental predictors influenced malaria incidence-rates, even in areas with declining trends. We highlight the impact of seasonally sensitive DTR, especially in the first two quarters of the year and demonstrate how substantial investment in intervention programmes is negatively impacted by near-term climate change, most notably since 2010. We argue for targeted seasonally-sensitive malaria chemoprevention programmes.
