  • Power management policies and control of hybrid electric vehicle

    With increasing concern over the environment and ever-stringent emission regulations, the use of hybrid electric vehicle (HEV) is being investigated as an alternative form of transportation. A hybrid vehicle combines the advantages of an electric drive and an internal combustion engine. This paper proposes the necessary hardware and software needed for an effective control of the electrical part ...

  • Sustainable improvement of drinking water quality by nanofiltration powered by renewable energy

    Desalination membrane technology is increasingly used for water production. However, the main disadvantage of desalination is related to energy consumption and CO2 emissions, so desalination powered by renewable energy (RE) is getting interest. In this study nanofiltration (NF) membranes have been used for drinking water quality improvement in a pilot plant (50 m3/day) powered by RE ...

  • Photocatalytic hydrogen production of the CdS/TiO2-WO3 ternary hybrid under visible light irradiation

    An attractive and effective method for converting solar energy into clean and renewable hydrogen energy is photocatalytic water splitting over semiconductors. The study aimed at utilizing organic sacrificial agents in water, modeled by formic acid, in combination with visible light driven photocatalysts to produce hydrogen with high efficiencies. The photocatalytic hydrogen production of ...

  • Calcium Carbonate, a solution to the energy crisis!

    A 'chemical' solution exists to solve jointly the energy crisis and CO2 release. Thanks to the Lime, “Cycle C4” could produce liquid fuels (petrol, diesel, etc.) with no CO2 release. The cycle presents no technological uncertainty, each step is widely known and controlled. Profitable with a barrel quote at 100 dollars. In 2004, the International Energy Agency annual report predicted that oil ...


  • Legislation Note: Climate Change and Sustainable Energy Act 2006

    The Climate Change and Sustainable Energy Act 2006 is in many ways typical of the hybrid measures taken to link energy and environmental issues. Until very recently, the government’s approach to energy policy was somewhat limited, as illustrated by the 2003 White Paper and mindful of its environmental obligations under the Kyoto Protocol. The 2007 White Paper – Meeting the Energy Challenge – sees ...


  • On energy, we`re finally walking the walk

    The United States has entered a new energy era, ending a century of rising carbon emissions. As the U.S. delegation prepares for the international climate negotiations in Copenhagen in December, it does so from a surprisingly strong position, one based on a dramatic 9 percent drop in U.S. carbon emissions over the past two years and the promise of further huge reductions. Prominent among these ...


  • Energy and exergy analysis of a novel multigeneration system producing cooling, heating, power and pure water

    A novel multi–generation system producing power, pure water, cooling and heating is proposed and analysed in detail. The system comprises a hybrid generator-absorber heat exchanger (GAX), the Organic Rankine Cycle (ORC), the absorption heat transformer (AHT) and a desalination system. For comparison purposes, three working fluids, including R123, Isopentane and n–butane are considered in the ORC. ...

  • Sustainable desalination technologies for future

    This paper deals with some aspects concerning the dual objectives of cost-effectiveness and favourable environmental impact of desalination plants, resulting in a sustainable alternative source of fresh water for future needs. These include some case studies on the use of waste heat for the thermal desalination plants, replacement of conventional pre-treatments in membrane plants with cleaner ...

  • Battery Storage will have a Profound Impact on Smart Buildings

    Often the best ideas are the most simple and elegant. If electric vehicles and consumer devices can have battery storage why can’t buildings? And if buildings can pull electricity from the grid at off peak times and store it in batteries, wouldn’t that save money? Since 2009, Stem based in California, have been working on these questions and disrupting the energy storage industry. ...

  • Who gets the EE stimulus money?

    The ink is dry on President Obama’s signature to the federal stimulus bill and word is out that energy efficiency receives more than US$20 billion. How will homeowners and businesses benefit? Two sources offer an excellent break-down on the incentives: the Alliance to Save Energy and the Office of Energy Efficiency and Renewable Energy, a unit of the US Department of Energy. EERE goes so far as ...

  • Lithium Ion Battery testing for vehicles

    Introduction Lithium-ion batteries are used in many types of devices including over 60% of mobile phones and 90% of laptop computers. These batteries are inside iPods and iPads, as well as military and medical hardware. They are even powering pacemakers in the human body. However, the most significant growth in demand for Lithium-ion batteries is in the hybrid/electric vehicle market. This ...

  • Environmental Policies under Obama: Is change in the air?

    As the Democratic candidate for President, Illinois Senator Barack Obama laid out his key strategies for energy and the environment. As detailed in campaign speeches and on his official Web site Obama promised a comprehensive New Energy for America plan that would accomplish the following goals:  Provide short-term relief to American families facing pain at the pump;  Help create five ...

  • It’s the environment, stupid

    If Harry Truman were running for president today, he’d probably ‘Give ‘em Green,’ rather than ‘Give ‘em Hell.’ Bill Clinton’s campaign slogan would be, ‘It’s the environment, stupid.’ And Herbert Hoover might be promising a solar panel on every roof, rather than a chicken in every pot – and the pot would sit on a smart-metered stove, powered by a plug-in hybrid, eligible for renewable energy ...

  • Desalination plant in Egypt runs on wind & sun

    Fortis Wind Energy (NL) and Juwi Renewable (DE) install a 100kW hybrid system in Egypt. Egypt, the land of the pyramids, is known to us for its ancient culture and the last year because of the uprisings for more democracy. Egypt is less known for its large population (83 million) lives along the Nile (only 5.5% of the surface). The rest of the country is desert. The River Nile runs into Egypt ...

  • Is today`s intereste in efficiency a blip

    Political leaders push energy efficiency when electricity rates spike, then drop it like a hot potato when prices fall. So how long will the current interest last? Three reports out this week indicate power prices will not ease any time soon. Indeed, forces are in place to only push costs higher. One force is the renewable portfolio standard, according to Standard & Poor’s Ratings Services ...

  • Top ten long term trends of cleantech in the United States

    In the last decade, the United States have been continuing to decrease its dependence on fossil fuels by investing into clean technologies, including renewable energy and energy efficiency. Because of such, the United States has been able to make the country a lot healthier, decreasing fossil fuel usage, and making the environment better and healthier. The United States Military Becoming ...

  • Will the climate change landscape shift with Obama at the helm?

    Those with a vested interest in energy, the environment and climate change are probably well aware of President-elect Barack Obama’s position?. The Obama-Biden ticket campaigned with an aggressive environmental platform that includes implementation of an economy-wide cap-and-trade program to reduce greenhouse gas emissions 80 percent by 2050. The proposed cap-and-trade policy will require all ...


  • Will Obama come through on his Environmental Election pledges?

  • U.S. headed for massive decline in carbon emissions*

    For years now, many members of Congress have insisted that cutting carbon emissions was difficult, if not impossible. It is not. During the two years since 2007, carbon emissions have dropped 9 percent. While part of this drop is from the recession, part of it is also from efficiency gains and from replacing coal with natural gas, wind, solar, and geothermal energy. The United States has ended a ...
