Demand for clean energies efficient development in building technologies

Abstract

The increased availability of reliable and efficient energyservices stimulates new development alternatives. This article discusses thepotential for such integrated systems in the stationary and portable powermarket in response to the critical need for a cleaner energy technology.Throughout the theme several issues relating to renewable energies,environment, and sustainable development are examined from both current andfuture perspectives. It is concluded that green energies like wind, solar,groundsource heat pumps, and biomass must be promoted, implemented, anddemonstrated from the economic and/or environmental point view. Biogas frombiomass appears to have potential as an alternative energy source, which ispotentially rich in biomass resources. This is an overview of some salientpoints and perspectives of biogas technology. The current literature isreviewed regarding the ecological, social, cultural and economic impacts ofbiogas technology. This article gives an overview of present and future use ofbiomass as an industrial feedstock for production of fuels, chemicals and othermaterials. However, to be truly competitive in an open market situation, highervalue products are required. Results suggest that biogas technology must beencouraged, promoted, invested, implemented, and demonstrated, but especiallyin remote rural areas. Anticipated patterns of future energy use and consequentenvironmental impacts (acid precipitation, ozone depletion and the greenhouseeffect or global warming) are comprehensively discussed in this article. NationalCentre for Research, Energy Research Institute (ERI), between January 2011 andJuly 2011. An approach is needed to integrate renewable energies in a way tomeet high building performance. However, because renewable energy sources arestochastic and geographically diffuse their ability to match demand isdetermined by adoption of one of the following two approaches: the utilisationof a capture area greater than that occupied by the community to be supplied, orthe reduction of the community’s energy demands to a level commensurate withthe locally available renewable resources. The adoption of green or sustainableapproaches to the way in which society is run is seen as an important strategyin finding a solution to the energy problem. The key factors to reducing andcontrolling CO2, which is the major contributor to global warming, are the useof alternative approaches to energy generation and the exploration of how thesealternatives are used today and may be used in the future as green energysources. This study highlights the energy problem and the possible saving thatcan be achieved through the use of renewable energy technologies. Also, thisstudy clarifies the background of the study, highlights the potential energysaving that could be achieved through use of renewable energy technologies anddescribes the objectives, approach and scope of the study. The move towards ade-carbonised world, driven partly by climate science and partly by thebusiness opportunities it offers, will need the promotion of environmentallyfriendly alternatives, if an acceptable stabilisation level of atmosphericcarbon dioxide is to be achieved. This requires the harnessing and use ofnatural resources that produce no air pollution or greenhouse gases andprovides comfortable coexistence of human, livestock, and plants. The increasedavailability of reliable and efficient energy services stimulates newdevelopment alternatives. We present and focus a comprehensive review of energysources, and the development of sustainable technologies to explore theseenergy sources. We conclude that using renewable energy technologies, efficientenergy systems, energy savings techniques and other mitigation measuresnecessary to reduce climate changes.
