Néhány cikk a szolár, szél- és bioenergia hasznosításáról, a vízkezelés fontosságáról és téma-javaslatok a 2012-es UNEP konferenciához
U.S. Billion-Ton Update: Biomass Supply for a Bioenergy and Bioproducts Industry. U.S. Department of Energy. August 2011.
The report examines the nation’s capacity to produce a billion dry tons of biomass resources annually for energy uses without impacting other vital U.S. farm and forest products, such as food, feed, and fiber crops. It provides industry, policymakers, and the agricultural community with county-level data and includes analyses of current U.S. feedstock capacity and the potential for growth in crops and agricultural products for clean energy applications. The biomass resources identified in the report could be used to produce clean, renewable biofuels, biopower, or bioproducts.
Solar Power. Pew Center on Global Climate. August 2011.
Solar power harnesses the sun’s energy to produce electricity. Solar energy resources are massive and widespread, and they can be harnessed anywhere that receives sunlight. The amount of solar radiation, also known as insolation, reaching the earth’s surface every hour is more than all the energy currently consumed by all human activities annually. A number of factors, including geographic location, time of day, and current weather conditions, all affect the amount of energy that can be harnessed for electricity production or heating purposes.
Wind Power. Pew Center on Global Climate Change. August 2011.
Wind power harnesses the energy generated by the movement of air in the earth’s atmosphere to drive electricity-generating turbines. Although humans have used wind power for hundreds of years, modern turbines reflect significant technological advances over early windmills and even over turbines from just ten or twenty years ago. Wind resource potential varies significantly across the United States with substantial resources found in the Midwest and along the coasts, according to the report.
Smart Grid. Pew Center on Global Climate Change. August 2011.
The smart grid refers to the application of digital technology to the electric power sector to improve reliability, reduce cost, increase efficiency, and enable new components and applications. Compared to the existing grid, the smart grid promises improvements in reliability, power quality, efficiency, information flow, and improved support for renewable and other technologies.

Making Progress on Global Water, Sanitation, and Hygiene (WASH) Challenges. Center for Strategic & International Studies. Katherine Bliss and Katryn F. Bowe. Aug 11, 2011.
This report presents conclusions and recommendations offered at a World Water Day Learning Forum, “Making Progress on Global Water, Sanitation, and Hygiene (WASH) Challenges,” held at CSIS on March 21, 2011. Sessions focused on the role of the private sector in water supply; achieving operational sustainability; the relevance of climate change adaptation programs for the WASH sector; and how to promote transparency and accountability within WASH programs. The report highlights the importance of community engagement, private sector involvement, and a commitment to the monitoring and evaluation of projects as critical factors in promoting WASH program sustainability.
Global Environmental Quality: Recommendations for Rio+20 and Beyond. Brookings Institution. William Brown. August 8, 2011.
In June 1972, the United Nations convened the UN Conference on the Human Environment in Stockholm. The conference led to the establishment of the United Nations Environment Programme (UNEP) and produced a declaration whose first principle states: “Man has the fundamental right to freedom, equality and adequate conditions of life, in an environment of a quality that permits a life of dignity and well-being, and he bears a solemn responsibility to protect and improve the environment for present and future generations.” The next conference is scheduled for June 2012, once again in Rio de Janeiro. The author presents his recommendations.
