  • "Energy for a Warming World" challenges the commonplace notion that the amount of power which mankind can potentially harness from renewable resources is more than large enough to assuage future demand levels. By examining the renewable issue from an electrical engineering perspective, and exercising due regard for the limited capability of current and future electrical generation and transmission systems, this book attempts to provide more realistic statistics for the levels of power which could be extracted from sustainable resources in the critical time frame of 30 to 40 years....

  • Wind energy is one of the most prominent renewable energy sources today. The increasing concerns with environmental issues are driving the search for more sustainable electrical sources. Wind energy along with solar energy, biomass and wave energy are possible solutions for environmentally friendly energy production. The initialization of wind power installation, which started in the beginning of 1980s, is very much related to the oil crises of the mid 1970s.

  • There is an estimated 1.4 billion km3 of water in the world but only approximately three percent (39 million km³) of it is available as fresh water. Moreover, most of this fresh water is found as ice in the arctic regions, deep groundwater or atmospheric water. Since water is the source of life and essential for all life on the planet, the use of this resource is a highly important issue. 'Water management' is the general term used to describe all the activities that manage the optimum use of the world’s water resources....

  • The decline in the economy, particularly in the second half of 2008, likely contributed to smaller gains in participants relative to previous years and a number of programs reported losses in the total number of participants. Perhaps surprisingly, nonresidential participant growth was on par with 2007; while the reason for this increase is unclear, one possible explanation could be heightened interest in renewable energy issues in an election year in which renewables and climate change were a focus.

  • As we sit at the microscope with users, waiting for data to collect, we frequently find ourselves answering the same questions, time after time. The users need to know what their data tells them about the sample, how it should be interpreted or processed, or a myriad of other details about the experiment. At other times, we find ourselves explaining why a particular experiment cannot be performed, or, at least, why it is more complex than appears at first glance. Sometimes students need help describing these issues to their advisors.

  • Energy is important for the existence and development of humankind and is a key issue in international politics, the economy, military preparedness, and diplomacy. To reduce the impact of conventional energy sources on the environment, much attention should be paid to the development of new energy and renewable energy resources. Solar energy, which is environment friendly, is renewable and can serve as a sustainable energy source. Hence, it will certainly become an important part of the future energy structure with the increasingly drying up of the terrestrial fossil fuel.
