"Advances in Renewable Energy Research comprises papers delivered at an international workshop by authors from Poland, Germany, Ukraine, China, Japan and Taiwan. The papers discussed the development of renewable energy technologies in certain countries, with special attention deviated to the conducted scientific research.The main focus is the use of biomass, which uses resources that are readily-available in large quantities in all countries. The experience related to the use of biomass for energy generation was presented for certain countries, i.e. Germany and Japan as representatives of the most advanced countries in the field of energy generation from renewable sources, Taiwan and Poland, which have some experience in that area as well, and China and Ukraine, which have just started the introduction of renewable energy technologies. The greatest attention was devoted to the biogas production methods, i.e. chemical, biological, and mechanical pre-treatment methods, as well as enhancement of anaerobic fermentation and purification of the biogas produced. The development of solar (photovoltaic and thermal) methods and the use of heat pumps in residential buildings are also discussed, mostly with Polish experience as an example. Special attention is paid to research methods to be used for development of renewable energy technologies. Advances in Renewable Energy Research is useful for engineers and researchers working in the renewable energy area."--Provided by publisher.
