Due to its compatibility with the current energy infrastructures and the potential to reduce CO2 emissions significantly, CO2 capture and geological storage is recognised as one of the main options in the portfolio of greenhouse gas mitigation technologies being developed worldwide. The CO2 capture technologies offer a number of alternatives, which involve different energy consumption rates and subsequent environmental impacts While the main objective of this technology is to minimise the atmospheric greenhouse gas emissions, it is also important to ensure that CO2 capture and storage does not aggravate other environmental concerns This requires a holistic and system-wide environmental assessment rather than focusing...
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.
The article argues that the currently dominant idea of material welfare is at odds with a lifestyle that does justice to basic human values. Measurement of welfare needs to attach importance to a good environment. With regard to the subjective counterpart: social research on the experience of welfare - the quality of life - in various Western countries shows clearly that intangible values are very important in the lives of most people. In a process of globalization of economy and cultural supplies, it will be important to strengthen democratic concern with the environmental question. The legitimation of political authority in (inter)national negotiations will depend on the attention paid to welfare and quality of...

In order to promote the production and use of electricity generated from renewable energy sources, support schemes such as the Renewables Portfolio Standard and various green power programs have been implemented. When evaluating the costs and benefits associated with those schemes, people need accurate information about the characteristics of renewable generation. The objective of the present paper is to identify the kind of information to be provided to lay people in Japan in order to enhance their understanding of biomass generation. We used the two-stage "mental model" method to conduct open-ended interviews and a questionnaire survey to reveal people's beliefs about biomass generation. From the survey results,...

To investigate the potential response of soils to climatic change, measurements of soil physical and chemical properties were carried out during a year in a mountain zone in Alicante (Spain), along an altitudinal and climatological gradient. Hydrological properties (infiltration runoff and sediment concentration) were measured under winter and summer conditions. Chemical and physical soil properties were analyzed for reference soil profiles along the transect. The erosional response of the soils as well as soil properties like organic matter and CEC are found to be under the direct influence of the climate, and as a result they have to be considered as important factors in the desertification processes.
ELECTRICITY GENERATED FROM WIND POWER WILL PLAY AN IMPORTANT ROLE in the future energy supply in many countries. This implies the need to integrate this power into the existing electricity supply system, which was mainly designed for large units of fossil fuel and nuclear power stations. Wind power has different characteristics and therefore this integration leads to some important challenges from the point of view of the electricity system. The availability of the power supply generated from wind energy varies fundamentally from that generated conventionally from fossil fuels. The most important difference is that wind power generation depends on the availability of the wind; i.e., it is weather dependent. In the...
