  • New methods for measuring the wind

    Although computer models of wind flow over terrain have improved dramatically in the past few years, there is still no substitute for data recorded at the site. So you want to build a wind farm. Good for you. With the global drive towards a low carbon economy, it is surely the right way to go for many individuals, companies and, indeed, Governments around the world. As information from the ...


  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • Sizing the clean economy: a national and regional green jobs assessment

    The "green" or "clean" or low-carbon economy-defined as the sector of the economy that produces goods and services with an environmental benefit-remains at once a compelling aspiration and an enigma. As a matter of aspiration, no swath of the economy has been more widely celebrated as a source of economic renewal and potential job creation. Yet, the clean economy remains an enigma: hard to ...

  • Risk zoning in relation to risk of external events (application to IRIS design)

    The design basis for any plant and site is closely related to the effects of any postulated external events and the limitation of the plant capability to cope with accidents, that is to perform safety functions. As a prime example of an advanced reactor and Nuclear Power Plant (NPP) with enhanced safety, the International Reactor Innovative and Secure (IRIS) has been considered in this work. In ...

  • Massachusetts Water Resources Authority (MWRA) – Boston and suburbs - Case Study

    The MWRA is a state government agency that provides wholesale water and sewer services to 2.5 million people and more than 5,500 large industrial users. It also monitors outflows in Cape Cod Bay and Boston Harbor using a range of advanced technologies. As an industrial user of electricity, agency officials are looking to reduce economic volatility from electricity costs and to improve energy ...

  • Micro Hydro Systems A basic overview of a hydro system with components explained

    If you have a suitable site, harnessing the energy in a stream or creek can be the most cost-effective way to make renewable electricity. Compared to the sun and wind’s variability, a stream’s flow is relatively consistent, making microhydro-electric system output the most predictable of all the renewable energy (RE) electrical systems. Hydro resources are also the most site specific, ...

  • Hydro power myths Explains why various schemes such as a pool pumps or rain gutters or pumping water to a tank will not work

    Making electricity from falling water can seem like magic, and that’s led to lots of misconceptions. Here, we’ll separate fact from fiction when it comes to what microhydro systems can and cannot do. Residential-scale microhydro-electric systems have the reputation of being the holy grail of home renewableenergy (RE) systems. While they lack some of the hype, magic, and bling of ...

  • Change is the only constant

    2016 was a year of big changes for Lufft: A change in the ownership structure took place in January and in August I took the reins as the new Managing Director. After more than 100 days at the innovative measuring technology manufacturer with a long company history, I would like to share with you my experiences and impressions in the new position. What characterizes Lufft? A good mix! ...

  • TMY – typical meteorological year - What should it represent and what means P50, P70 and P90

    Technical Top Tip courtesy of Suntrace Solar Resource Assessment 1. What is a TMY? A Typical Meteorological Year (TMY) is a data set giving values in high time resolution. It shall well represent the characteristic meteorological conditions of average years at a site. Energy performance calculations to predict ...

  • 5 Ways Wisconsin Can Reduce Power Plant Emissions

    As the U.S. Environmental Protection Agency (EPA) moves forward with standards to reduce power plant emissions—which are due to be finalized in June 2015—many states are wondering how they will comply. WRI’s fact sheet series, Power Sector Opportunities for Reducing Carbon Dioxide Emissions, examines the policies and pathways various states can use to cost-effectively meet or ...

  • How to Keep Your SymphoniePRO Data Secure

    Data matters. The accuracy, consistency, and yes, safety of measurement data keep many wind developers and analysts up at night. Customers often ask about the digital and physical security of RNRG instruments, so I sat down with Michael Fisher, product manager for our wind resource assessment (WRA) line, to get answers to the most common questions. Q: Why is data security important? ...

  • Modeling Dispersion from Toxic Gas Released after a Train Collision in Graniteville, SC

    ABSTRACT The Savannah River National Laboratory (SRNL) Weather Information and Display System was used to provide meteorological and atmospheric modeling/consequence assessment support to state and local agencies after the collision of two Norfolk Southern ...

  • Can the Internet save the planet?

    Last October, environmentally conscious Netheads everywhere got some excellent news. The pervasive use of broadband Internet connections and the tools and practices they enable could reduce greenhouse gas emissions by some 1 billion tons over the next decade, according to the American Consumer Institute. Widespread adoption of broadband in the United States alone would cut energy use by the ...


  • Erosion and Sediment Control: Navigating NPDES Regulations, the SWPPP, and Techniques for Compliance

    Erosion and Sedimentation: Why Are They a Problem? The US Environmental Protection Agency lists sediment as the single most common pollutant in rivers, streams, lakes, and reservoirs. With all the potentially harmful chemicals and substances in the world, it seems odd to many people that sediment—dirt, essentially—is singled out as the major culprit. Yet these particles of ...

  • Green Careers: 400,000 environmental jobs by 2015

    The House of Commons Environmental Audit Committee (EAC) is currently conducting an inquiry into the prospects for green jobs and policies aimed at increasing employment in environmental industries. It will consider how the UK can maximise the environmentally positive opportunities arising from changes in public spending and how this might help with employment during the recession. The report ...


  • Urban greenery: Initiation to UEM

    I think that I shall never see a poem lovely as a tree. These words by American poet Joyce Kilmer capture the love most people share for trees. This sentiment may be especially appropriate in urban areas where trees are particularly noticeable and play critical roles in the quality of urban life. Trees are also major capital assets in our cities and towns as much an integral part of the scene as ...


  • Biosolids ban struck down

    In 1994, Los Angeles County Sanitation Districts (LACSD) bought a 4,700-acre farm (called Green Acres Farm) in southwest Kern County for the purpose of land applying biosolids from its 11 wastewater treatment plants. LACSD land applied 800 wet tons/day at this site for several years. In 2006, Kern County voters passed Measure E on the ballot with 83 percent approval. This measure banned ...

  • Urban sustainability issues — Resource-efficient cities: good practice

    Our current pattern of resource use is leading to the depletion and, consequently, scarcity of natural resources (1), the degradation of ecosystems and volatile and increasing prices of natural resources. On a planet with finite resources, the challenge is to find a way of delivering greater value and more services with fewer inputs (EC, 2011a). Resources are defined as raw materials, such as ...

  • Latest analytical technology ensures biogas efficiency

    Anaerobic Digestion (AD) relies on the ability of specific micro-organisms to convert organic material into a gas that can be used to generate electricity. However, these bacteria require specific conditions if they are to function effectively and instrumentation specialist company HACH LANGE has developed a range of online, portable and laboratory instruments that have enabled a large number of ...
