“We regard the recent science –based consensual reports that climate change is, to a large extend, caused by human activities that emit green houses as tenable, Such activities range from air traffic, with a global reach over industrial belts and urban conglomerations to local small, scale energy use for heating homes and mowing lawns. This means that effective climate strategies inevitably also require action all the way from global to local levels. Since the majority of those activities originate at the local level and involve individual action, however, climate strategies must literally begin at home to hit home.”

The use of renewable energies is imperative nowadays. One of the ways to use clean technologies is installation of photovoltaic systems which convert solar energy into electricity, through solar plants. The country?s potential for usage of solar energy is determined by the analysis of climatic conditions. The research is conducted on the example of a small-scale solar plant - a pilot project installed in the city of Nis, concerning the analysis of the mounted system and giving the recommendations for their design with the aim of improving efficient energy use. Limitations in the installation of solar plants can occur in the case of an unfavorable position of the building where the installation is planned, and more often, the limitations are related to the investment costs and length of the repayment period of these kinds of technologies. This paper represents a promotion of sustainable electricity supply for our country and it is in correlation with the legal directives of using renewable energies.

Global energy use has reached unprecedented levels and increasing human population, technological integration, and improving lifestyle will further fuel this demand. Fossil fuel based energy is our primary source of energy and it will remain to be in the near future. The effects from the use of this finite resource on the fate of our planet are only now being understood and recognised in the form of climate change. Renewable energy systems may offer a credible alternative to help maintain our lifestyle sustainably and there are a range of options that can be pursued. Biofuels, especially algae based, have gained significant publicity recently. The concept of making biofuels, biochemicals, and by-products works well theoretically and at small scale, but when considering scaleup, many solutions can be dismissed on either economical or ecological grounds. Even if an (cost-) effective method for algae cultivation is developed, other input parameters, namely, fixed nitrogen and fresh water, remain to be addressed. Furthermore, current processing routes for harvesting, drying, and extraction for conversion to subsequent products are economically unattractive. The strategies employed for various algae-based fuels are identified and it is suggested that ultimately only an integrated algal biorefinery concept may be the way forward.

Abstract In recent years, energy constraints have been discussed from a historical point of view. This study aims at examining the copper industry’s energy use in Japan from the Meiji period to the time of World War I and clarifying the process of, and reasons for, the selection of energy sources. This study considered not only energy use in the large-scale mines but also energy use in the small-scale mines and miners’ homes. As a result, it was clarified that the mines changed into a space that was based on a diverse combination of energy sources, depending on differences in location (access to energy), natural conditions, financial power, the required amount and price of energy, energy use technologies, ore quality, and end product (usage).

AbstractThere is now no doubt that current global production-consumption-disposal systems are threatening the fundamental conditions of existence on this planet. In response, the pressing need for total system transformation has gained civic and political traction, feeding into long-standing debates and interventions that are aimed at recalibrating prevailing economic and social practices. One such debate and intervention is that of the circular economy (CE). Here, advocates argue that current linear resource and energy use systems must be reconfigured into loops of re-use, repair, refurbishment, and recycling, displacing primary production and lessening greenhouse gas emissions in the process. This agenda has potentially profound implications for aspects of daily social practices. Yet, to date, little attention has been paid (politically and in research) to how the CE does and will interact with everyday habits, norms, and meanings. In response, this paper explores some of the conceptual assumptions underlying the CE ‘consumer’. It argues that mainstream CE debates are underscored by an impoverished view of our relationships with complex material cultures, which in turn is creating barriers to transformation. Drawing on empirical research into responses to the CE in the UK and the Netherlands, this paper contrasts the challenges of inciting consumers to take up new, resource-efficient business models in contexts of hyper-consumerism, with a more hopeful ‘small story’ of overt, small-scale circular spaces, that nevertheless embed the CE and its underlying impetuses more clearly into the everyday.
