  • Domestic heating systems are more efficient with Scalewatcher

    In hard water areas plumbing, hot water systems and appliances quickly become encrusted with limescale resulting in increasing energy bills and the early renewal of boilers and appliances.  The award-winning, patented, Scalewatcher water-conditioner, from Scalewatcher North America, offers a simple and permanent solution to limescale thereby reducing energy bills and making heating systems ...

  • 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 ...

  • Energy efficiency: The unsung hero of our times

    As our economy continues to sputter, one little-noticed industry has been booming for a while now: energy efficiency. The sector is hiring like crazy -- a fact that speaks volumes about the close relationship between clean energy and the economic recovery that we're all waiting for. Energy efficiency could save us all. My firm works with utilities, government agencies, housing authorities, and ...

  • The natural gas revolution: Good or bad for energy efficiency?

    If there were an equivalent in the energy industry to Time Magazine’s Person of the Year, natural gas would be this year’s winner. The dramatic rise in natural gas supply, and fall in price, has reconfigured the energy scene in the United States, suddenly creating a bounty of domestic energy, driving down wholesale power prices and speeding retirement of polluting coal-fired plants. ...

  • Energy efficiency: Big deals and new ideas

    The economic premise behind energy efficiency –  that it’s cheaper to save a unit of energy than to make one – has caught on in the US.  Energy efficiency spending is up, and our energy use is declining, measured both per capita and per dollar of gross domestic product, according to government ...

  • Energy Efficient Products: the case of Latin America

    Companies manufacturing and selling appliances, equipment and lighting in Latin America (LA) face a growing demand from governments and consumers: reducing energy consumption. In a region of about 20 countries, where Spanish is the dominant language and regulatory systems are based on similar legal models, this demand wouldn’t seem to be a significant regulatory problem to energy-using ...

  • Building Energy Management Systems (BEMS) Frequently Asked Questions

    The Building Energy Management Systems (BEMS) sector is growing as organisations realise that BEMS are one of the most effective solutions for optimising efficiency in a building - providing the quick win that organisations are seeking. Energy managers and building owners might have ...

  • The Energy Revolution is Here

    We live in an exciting time. Yes, glaciers are melting, sea levels are rising, and in my new home in the Western United States, earlier snowmelts, longer summers, and hotter temperatures have made wildfires 400 percent more frequent. And yet, there are encouraging signs we are in the midst of an energy revolution that is sure to transform our climate, our economy, and our lives for the better. ...

  • Case study - Bank energy costs

    There are many pleasures of living and working in the Cayman Islands. However, paying utility bills for your business on Cayman isn’t one of them. The island territory has particularly high energy costs because Cayman has few domestic energy resources. Most electricity on Cayman is produced from imported diesel fuel, which is very expensive. As a result, businesses on Grand Cayman pay ...

  • We don’t want energy storage

    Claiming that we don’t want energy storage seems like a provocative thing to say. For example, the Energy Institute (EI)’s 2015 Energy Barometer report, a survey of professionals in the energy industry, rated storage as the area most in need of innovation. My point isn’t that energy storage isn’t ...

  • Geothermal Energy... Power from the Depths

    The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...

  • Presidents’ reflections 100 – A century of energy professionalism

    1. In May 1978, I chaired the AGM which saw  members sensibly approve the motion that the  name of the Institute of Fuel be changed to the  Institute of Energy, despite strong resistance  from the “old guard” members of Council. My  period in office coincided with the “Winter of  Discontent” and the run-up to the May 1979  election, which ...

  • CSP Today speaks with SASIA about the future of Solar Energy in the Middle East

    With the lead-up to MENASOL 2013, Browning Rockwell Founder and Director of SASIA (Saudi Arabia Solar Industries Association) shares his views on both CSP and PV in the MENA region. Now that the industry has had time to consider the 54GW renewable energy strategy in place for Saudi Arabia for 2032, what are your conclusions? I still believe its early days as it’s been ...

  • 7 Theses on Storage Systems in Commercial Applications

    Solar storage systems are now the focus of attention more than ever before. The application areas are as different as the requirements. While private PV system operators work toward optimizing self-consumption, storage systems in industry are mainly used to provide control reserve and thus ensure grid stability. In commercial storage ...

  • Toasting Pop-Tarts cheap: How electricity may solve our energy woes

    We tend to talk about electricity in terms of its problems — it degrades the environment, costs too much and messes up scenic views. But the Manhattan Institute’s Peter Huber takes a different stand in his new report “The Million-Volt Answer to Oil.”Huber says electric power may be the cheap, efficient resource we seek to give America energy independence. He divides energy into two camps: ...

  • Ocean Thermal Energy conversion and the company bringing it to market: clean water for our children

    Water is the most life sustaining resource on earth. Essential to all aspects of our human lives, it serves as the key ingredient in food and drink, helps us fabricate clothes, landscapes our favourite places, drives economic growth and feeds agricultural development. Our bodies themselves are 70% water. This liquid of life keeps us hydrated, catalyses crucial chemical reactions within our cells ...

  • Progress of the European Union and its Member States towards 2020 climate and energy targets

    The 2016 edition of the annual European Environment Agency (EEA) 'Trends and projections' report confirms that the EU is well on track to meet its targets on greenhouse gas emission, renewable energy and energy efficiency set for 2020. Progress at Member State level is more nuanced. The 2016 edition of the annual European Environment Agency (EEA)Trends and projections in Europereport confirms ...

  • How the UK could save £8 Billion per Annum

    We know that buildings use about (40)% of all energy use and we also know that the energy efficiency of buildings can be greatly improved, often just by better monitoring and controls with low capex and fast paybacks. Savings of 20% or more can often be achieved by better control strategies and recommissioning. New design techniques such as integrative design of whole building retrofits can ...

  • Get more Bang for your Buck with Solar Thermal!

    The relative efficiency of renewable energy technologies – i.e. their ability to transform solar or wind energy into electricity and heat – is a key element in calculating the likely effectiveness and expected ROI of renewable installations. Recently published research shows that solar thermal technology is more efficient than any other renewable system. According to the latest ...
