  • Haiti Sustainable Energy Roadmap. Harnessing Domestic Energy Resources to Build a Reliable, Affordable, and Climate - Compatible Electricity System

    Haiti’s electricity sector stands at a crossroads. Haiti depends on imported petroleum for 85% of its electricity generation, diverting 7 percent of its annual gross domestic product to importing fuel. Still, only 25% of the Haitian population has regular access to electricity, bringing barriers to advances in economic opportunity, health, education, and social equality. Yet, according to ...

  • The Effectiveness of Combined heat and Power Solar Water Heating Systems

    Abstract: Solar water heating in residential and commercial buildings is often provided by integrating a large number of domestic thermosyphon solar water heaters. The economic effectiveness of solar Domestic hot water heating systems depends mainly on its types and configurations. Thereupon in this paper, simulation models have been presented for the modeling of thermal and electrical ...


  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • CPV solar power system

    There are relatively few CPV applications still pursuing Si cells. The idea was somewhat "hot", no pun intended, when there was a silicon shortage going on, but silicon prices have dropped as new capacity has come online and the only successful CPV concepts being marketed which I know of are based on triple junction Ge/GaAs/InGaP or similar cells. These are also rather heat sensitive, and the two ...

  • Water vapour permeation measurement for PV Solar Cell packaging

    With fears of carbon dioxide causing global warming and diminishing supplies of fossil fuels, a looming energy crisis is affecting all countries.  As a consequence, a great deal of world-wide effort is going into the development of alternative energy technologies.  At present, wind, hydro and geothermal are becoming well established with more niche roles for tidal and solar. The latter ...

  • Large-scale solar sludge drying in Managua/Nicaragua

    Within the framework of a programme aimed at reducing the biological contamination of Lake Managua, a central wastewater treatment plant for the city of Managua (1.1 million p. e.) was constructed and commissioned at the end of 2009. Annual sludge production amounts to 26,000 m3 and sludge disposal and/or reuse thus present a major challenge. Based on the results of extensive studies, the ...

  • Plan B 4.0 by the numbers - data highlights on solar energy

    Concerns about global warming, rising fossil fuel prices, and oil insecurity have prompted calls for a new energy economy, one that replaces fossil fuels with renewables. The sun is an enormous reservoir of energy; in fact, the sunlight reaching Earth in just one hour is enough to power the global economy for a whole year. Harnessing some of this energy is an essential component of Earth Policy ...

  • Renewable Energy a Big Employer with Solar Energy Sector in the Lead

    A new report from the International Renewable Energy Agency (Irena) has shown that the workforce in the global renewable energy industry in 2013 grew by 14% to 6.5million. Such statistics show that the sector has become a force to reckon with when it comes to employment worldwide. This report however contradicts the situation in the UK with the statistics stagnating from the most recent ...

  • Energy requirements for waste water treatment

    The actual mathematical models describing global climate closely link the detected increase in global temperature to anthropogenic activity. The only energy source we can rely on in a long perspective is solar irradiation which is in the order of 10,000 kW/inhabitant. The actual primary power consumption (mainly based on fossil resources) in the developed countries is in the range of 5 to 10 ...

  • A call to action (The need for an integrated national water policy)

    Introduction Why a National Water Policy . . . Why Now . . . Why Us?Human and economic development in this country has always been reliant on access to, and the availability of, water. Indeed, when faced with challenges to our water quantity and quality, America harnessed its technological expertise and management prowess to overcome them. Until recently, such abilities had ...

  • Case-study - Utilising waste heat for water production and climate control

    Water purification is needed to produce high quality water for consumption, agriculture and industrial needs. Conventional water treatment processes, like distillation and reverse osmosis, consume vast amounts of energy. However, there is a large potential for significant reductions in energy consumption and CO2 emissions in this sector. It can be achieved by the exploitation of waste heat for ...

    Introduction of wireless data collection and analysis improves leak detection and water supply efficiency Companies whose business is the delivery of water to consumers, do not only have a responsibility to provide high quality drinking water to both domestic and industrial users, but also to ensure that it is done so economically and reliably. The WLV association ...

  • What do oil sands and shale gas have in common? Acute need for sustainable water management solutions

    The world’s appetite for fossil fuels is not abating anytime soon, and the alternatives fall short. Nuclear energy makes people uneasy, coal is perceived as not being that clean, hydroelectric requires massive capital outlays, solar is still improving and the wind just doesn’t always blow. For the foreseeable future, North Americans have embraced the idea that expanded production of ...

  • Hotel Melia Las Dunas Cayo Santa Maria, Cuba – case study

    OVERVIEW The Hotel Melia Las Dunas has 925 rooms and suites. Fresh water arrives at the Hotel in a DN 200 steel pipe (8”). Water consumption daily average is 936 m3 (almost 250,000 US Gallons per day) with peak rates up to 190 m3/h (833 gpm). WATER SYSTEM CHALLENGES The domestic hot water for the site is produced by two sets of three boilers ...

  • Sustainable development with renewable energy resources: a review

    The most visible effects of the sustainable development movement are found in several global issues such as the greenhouse effect, stratospheric ozone depletion, and loss of biodiversity. Combustion of fossil fuels and global warming are closely associated with each other. There is an urgent need to replace fossil fuels to renewable energy sources. Renewable energy is one of the few means by ...
