Policy assessment of energy conservation strategies has tended to emphasize technological and economic costs, problems, and benefits. However, too narrow a focus may fail to delineate all the environmental and social impacts associated with the technology in question. In recognition of the importance of a balanced evaluation, a study was undertaken to identify local-level perceptions about environmental and social problems and opportunities associated with several energy conservation measures. These measures included building performance standards and retrofit; waste heat utilization; modifications in land use configurations and transportation modes; and electric utility demand management, and rate reform initiatives....
Long-term greenhouse gas emission reduction strategies for the Netherlands were studied, using a MARKAL energy model. The EMS study identifies longterm technological options for greenhouse gas emission reduction and assesses their cost-effectiveness, taking interactions between technologies into account. The project consisted of three parts: carbon dioxyde (CO 2) emission reduction in the energy system, integrated reduction of greenhouse gases from the energy system with consideration of upstream emissions and CO 2 reduction in the integrated energy and materials system. 500 energy technologies were assessed for their reduction potential. Significant emission reduction seems possible, but it takes an array of measures...
Energy autarky is presented as a conceptual framework for implementing sustainable regional development based on the transformation of the energy subsystem. It is conceptualized as a situation in which the energy services used for sustaining local consumption, local production and the export of goods and services are derived from locally renewable energy resources. Technically, the implementation of higher degrees of energy autarky rests on increasing energy efficiency, realizing the potential of renewable energy resources and relying on a decentralized energy system. Practically, a transition towards regional energy autarky requires administrations and civil society actors to initialize and develop projects at...
High-temporal resolution meteorological output from the Parallel Climate Model (PCM) is used to assess changes in wildland fire danger across the western United States due to climatic changes projected in the 21st century. A business-as-usual scenario incorporating changing greenhouse gas and aerosol concentrations until the year 2089 is compared to a 1975 - 1996 base period. Changes in relative humidity, especially drying over much of the West, are projected to increase the number of days of high fire danger ( based on the energy release component (ERC) index) at least through the year 2089 in comparison to the base period. The regions most affected are the northern Rockies, Great Basin and the Southwest - regions...
Energy subsidies are widespread around the world but they vary greatly in importance and type of fuel and country. The fossil fuel consumption rate is growing every year and in about 50 years we will have depleted most of our fossil fuel reserves, so it is necessary to find alternative sources of energy before that happens. However, the only solution to this challenge is through investment on energy conservation programmes and renewable energy source. In line with this challenge and confusion on fund appropriate for energy. This paper is aimed at examining the effect of energy subsidy on energy conservation and renewable energy in developing countries. The study intends to quantify and analysis a case study of Trinidad...
This paper considers the issue of whether shocks to ten commodity prices (gold, silver, platinum, copper, aluminum, iron ore, lead, nickel, tin, and zinc) are persistent or transitory. We use two recently developed unit root tests, namely the Narayan and Popp (NP) [14] test and the Liu and Narayan (LN) [26] test. Both tests allow for two structural breaks in the data series. Using the NP test, we are able to reject the unit root null for iron ore and tin. Using the GARCH-based unit root test of LN, we are able to reject the unit root null for five commodity prices (iron ore, nickel, zinc, lead, and tin). Our findings, thus, suggest that only shocks to gold, silver, platinum, aluminum, and copper are persistent.

Coal is the one fossil energy source that can play a substantial role as a transitional energy source as one moves from the petroleum and natural gas based economic system to the future economic system based on nondepletable or renewable energy systems. For coal to remain competitive with other sources of energy in the industrialized countries of the world, continuing technological improvements in all aspects of coal extraction have been necessary. Coal has many important uses, but most significantly in electricity generation, steel and cement manufacture, and industrial process heating. Despite the long-term importance of oil and gas use, coal will remain a major pillar of the world’s energy supply. Developing...

Two field studies revealed large differences among various subgroups in the population of car drivers. Private drivers, commuters, and business drivers differed strongly with respect to current decisions and behaviour which affect CO2 emissions, and with respect to their sensitivity to various policy instruments. Several promising policy targets were identified" combinations of user groups and behaviours where substantial CO2 reduction may be achieved. The sensitivity of different car user groups to various policy measures showed whether and how desired behavioral changes may be realised.
Community energy initiatives offer a potentially important means for reshaping the electrical system in a manner compatible with emissions reduction goals. Many such initiatives, however, focus upon top-down, institutionally structured approaches that understand community residents as atomistic, economically motivated, and minimally engaged. This paper examines a number of case studies that are based upon a bottom-up approach rooted in a civic culture that seeks to maximize the capacities of an active and engaged citizenry. The paper focuses upon two mutually dependent issues: first, recruiting community members, and second, sustaining their participation.
This paper empirically examines the dynamic causal relationships between carbon dioxide emissions, energy consumption, economic growth, trade openness and urbanization for the panel of newly industrialized countries (NIC) using the time series data for the period 1971–2007. Using four different panel unit root tests it is found that all panel variables are integrated of order 1. From the Johansen Fisher panel cointegration test it is found that there is a cointegration vector among the variables. The Granger causality test results support that there is no evidence of long-run causal relationship, but there is unidirectional short-run causal relationship from economic growth and trade openness to carbon dioxide emissions,...

A complete understanding of the resource consumption, embodied energy, and environmental emissions of civil projects in China is difficult due to the lack of comprehensive national statistics. To quantitatively assess the energy and environmental impacts of civil construction at a macro-level, this study developed a 24 sector environmental input-output life-cycle assessment model (I-O LCA) based on 2002 Chinese national economic and environmental data. The model generates an economy-wide inventory of energy use and environmental emissions. Estimates based on the level of economic activity related to planned future civil works in 2015 are made. Results indicate that the embodied energy of construction projects accounts...
