چکیده

• Hazardous chemicals pose a substantial accident risk in deep geothermal energy system. Expected is highest during stimulation followed by drilling and plant operation. Hydrochloric acid dominates expected of the analyzed blowouts. The operational phase exhibits extreme events related risk. Deep performs better than fossil, hydropower, hydrogen biogas technologies. In this study, comparative assessment with focus on systems Organization for Economic Co-operation Development (OECD) countries presented. evaluation often focused geotechnical risks, such as induced seismicity, social acceptance rather risks. However, comprehensive analysis should include additional technical aspects, blowouts well transportation, storage use hazardous substances. This research characterizes quantifies different technological risks associated systems. Risk indicators are calculated to phases, substances drilling, stimulation, phases. A comparison between identified carried out, showing that phases exhibit respectively. Finally, technologies showed similar wind offshore (worst case scenario) or even slightly solar photovoltaic (best case), outperforms chains.

CO 2 emissions attributed to annual average electricity consumption in OECD ( the Organisation for Economic Co - operation and Development ) countries

When regulating GHG emissions at the country or product level, it is critical to determine the GHG emissions from electricity consumption. In this study, we calculated production-based and consumptionbased CO2 emission intensities of electricity for the OECD (the Organisation for Economic Co-operation and Development) countries during 1990e2008. We examined the impact of annual development, all...

Challenges for health systems in member countries of the Organisation for Economic Co-operation and Development.

For reasons of equity most OECD countries have chosen to base their funding of health care mainly on public sources. There is an almost universal problem of affordability in the health systems of these countries, arising from the tension between the willingness of populations to pay taxes and the eagerness of patients to use health services where these are free or heavily subsidized at the poin...
