Bioenergy and land use change
\"Although bioenergy is a renewable energy source, it is not without impact on the environment. Both the cultivation of crops specifically for use as biofuels and the use of agricultural byproducts to generate energy changes the landscape, affects ecosystems, and impacts the climate. Bioenergy and Land Use Change focuses on regional and global assessments of land use change related to bioenergy and the environmental impacts. This interdisciplinary volume provides both high level reviews and in-depth analyses on specific topics. Volume highlights include: land use change concepts, economics, and modeling; relationships between bioenergy and land use change; impacts on soil carbon, soil health, water quality, and the hydrologic cycle; impacts on natural capital and ecosystem services; effects of bioenergy on direct and indirect greenhouse gas emissions; biogeochemical and biogeophysical climate regulation; and uncertainties and challenges associated with land use change quantification and environmental impact assessments. Bioenergy and Land Use Change is a valuable resource for professionals, researchers, and graduate students from a wide variety of fields including energy, economics, ecology, geography, agricultural science, geoscience, and environmental science\" -- Provided by publisher.

Specific Energy Consumption/Use (SEC) in Energy Management for Improving Energy Efficiency in Industry: Meaning, Usage and Differences
Although several research studies have adopted specific energy consumption (SEC) as an indicator of the progress of improved energy efficiency, publications are scarce on critical assessments when using SEC. Given the increasing importance of monitoring improved industrial energy efficiency and the rising popularity of SEC as an energy key performance indicator (e-KPI), an in-depth analysis and problematization on the pros and cons of using SEC would appear to be needed. The aim of this article is to analyse SEC critically in relation to industrial energy efficiency. By using SEC in the pulp and paper industry as an example, the results of this exploratory study show that although SEC is often used as an e-KPI in industry, the comparison is not always straightforward. Challenges emanate from a lack of information about how SEC is calculated. It is likely that SEC is an optimal e-KPI within the same study, when all deployed SECs are calculated in the same way, and with the same underlying assumptions. However, before comparing SEC with other studies, it is recommended that the assumptions on which calculations are based should be scrutinized in order to ensure the validity of the comparisons. The paper remains an important contribution in addition to the available handbooks.

Energy Sprawl or Energy Efficiency: Climate Policy Impacts on Natural Habitat for the United States of America
Concern over climate change has led the U.S. to consider a cap-and-trade system to regulate emissions. Here we illustrate the land-use impact to U.S. habitat types of new energy development resulting from different U.S. energy policies. We estimated the total new land area needed by 2030 to produce energy, under current law and under various cap-and-trade policies, and then partitioned the area impacted among habitat types with geospatial data on the feasibility of production. The land-use intensity of different energy production techniques varies over three orders of magnitude, from 1.9-2.8 km(2)/TW hr/yr for nuclear power to 788-1000 km(2)/TW hr/yr for biodiesel from soy. In all scenarios, temperate deciduous forests and temperate grasslands will be most impacted by future energy development, although the magnitude of impact by wind, biomass, and coal to different habitat types is policy-specific. Regardless of the existence or structure of a cap-and-trade bill, at least 206,000 km(2) will be impacted without substantial increases in energy efficiency, which saves at least 7.6 km(2) per TW hr of electricity conserved annually and 27.5 km(2) per TW hr of liquid fuels conserved annually. Climate policy that reduces carbon dioxide emissions may increase the areal impact of energy, although the magnitude of this potential side effect may be substantially mitigated by increases in energy efficiency. The possibility of widespread energy sprawl increases the need for energy conservation, appropriate siting, sustainable production practices, and compensatory mitigation offsets.

Mindful exercise : metarobics, healing, and the power of tai chi /
This groundbreaking book demonstrates the link between health and metarobics, the author's term for slow, meditative exercises that enhance blood oxygen saturation, diffusion, and oxygen-based metabolism. Metarobics-- including tai chi, qigong, and yoga-- focus on movement, relaxation, and deep breathing. Dr. Gryffin's research shows that mindful exercises offer a wide range of benefits for treating chronic disease.--Publisher.

Financing energy efficiency : lessons from Brazil, China, India, and beyond
While energy efficiency projects could partly meet new energy demand more cheaply than new supplies, weak economic institutions in developing and transitional economies impede developing and financing energy efficiency retrofits. This book analyzes these difficulties, suggests a 3-part model for projectizing and financing energy efficiency retrofits, and presents thirteen case studies to illustrate the issues and principles involved.

Impact of Urban Form at the Block Scale on Renewable Energy Application and Building Energy Efficiency
Improving building energy efficiency and widespread application of renewable energy are key measures for achieving zero-emission development in the building sector in response to climate change. However, previous studies on buildings and renewable energy use have predominantly treated buildings as independent entities, overlooking the influence of urban morphology on both aspects. Conducting research on the impact of urban form on building energy consumption and renewable energy application at the block scale can contribute to more accurate predictions of renewable energy potential and building energy efficiency, thereby enhancing their synergistic relationship. In this context, this study proposes a methodology for building energy simulation and analysis of renewable energy potential in building clusters using the Grasshopper platform. Six typical residential building clusters in Beijing, selected based on the local climate zone system, are used as representative samples of urban forms at the block scale. Based on these samples, 30 building cluster prototypes have been constructed. By simulating the renewable energy potential and building energy consumption of these prototypes, the study analyzes the influence of urban form on both aspects. The results indicate that the heat island effect and obstruction effect between buildings are the main manifestations of urban form influence; in this case, the urban heat island effect can reduce the building heating energy consumption by 15.8% on average and increase the cooling energy consumption by up to 30%; the shading effect between buildings increases heating energy consumption by an average of 11.88% and reduces cooling energy consumption by 5.87%. These two factors have opposite effects on building energy efficiency and are correlated with urban form parameters, such as the sky view factor, street canyon height to street canyon width ratio, and floor area ratio. This study provides valuable insights for the application of renewable energy in buildings and the balance of energy supply and demand.
