  • Optimizing Wind and Solar Power in Africa

    Editor's Note: The following is a news release authored by Julie Chao and issued by Lawrence Berkeley National Laboratory on April 5, 2017 To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence ...

  • The effect of intermittent operation on a wind-powered membrane system for brackish water desalination

    Renewable energy powered membrane systems that are directly-connected must take account of both the inherent fluctuations and the intermittency of the energy resource. In order to determine the effect of intermittent operation, a membrane system was tested with variables of (i) amplitude from 60 to 300 W and (ii) length of time with no power from 0.5 to 3 min. This was performed over one hour ...

  • Full-energy-chain greenhouse-gas emissions: a comparison between nuclear power, hydropower, solar power and wind power

    Fair comparison of the climate impacts from different energy sources can be made only by accounting for the emissions of all relevant greenhouse gases (GHGs) from the full energy chain (FENCH) of the energy sources. FENCH-GHG emission factors of most of the non-fossil fuel energies are lower than those of the fossil fuels that are in the range of 500-1200 g CO2/kW h(e). The improvement ...

  • Integrated solar and wind energy powers oil recovery system

    Recovery of free-product petroleum at the former St. Croix Alumina (SCA) site in Kingshill on St. Croix, VI, is addressing ground-water contamination caused by past releases of fuel and refined petroleum at SCA. The oil recovery system employs wind-driven turbine compressors (WTCs), wind-driven electric generators (WEGs), and photovoltaic (PV) panels to power pneumatic and electric submersible ...

  • How will this new development in batteries make wind and solar power more completive?

    The trend is changing in obtaining energy from conventional sources to obtaining energy from solar and wind power units. The change in trend is due to this energy is considerably cheaper than the energy obtained from several other methods. Earlier an expensive metal was used over in the chargeable batteries for solar and wind units. Mostly these units contain platinum and other very expensive ...

  • Weather claims and wind safety

    Anybody working in the construction industry either here in the UK or anywhere else in the world is likely to know that the weather can present us with particular hazards. While rain, ice and snow are particularly dangerous to work in, we must always be aware that the wind is also likely to make conditions unsafe, particularly for those who work at height and those who ...

  • Wind & solar energy and nature conservation

    Climate change and the degradation of ecosystems and biodiversity cannot be solved in isolation. Land and marine ecosystems play a crucial role in the climate system, capturing roughly half of carbon dioxide emissions generated by human activities (UNEP, 2009). Protecting biodiversity preserves ecosystem services that are important for regulating the climate and helping us to adapt to the impacts ...

  • Sustainable power and innovation provide clean drinking water and energy

    In many areas in Kenya, access to clean drinking water is lacking. About 88% of the population must travel long distances to get to the nearest source of clean water or is forced to drink contaminated water. Children in particular suffer from waterborne diseases. Systems Provide Energy-Independent Water Treatment To try to provide a long-lasting solution for the drinking water needs ...

  • 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 ...

  • The flawed economics of nuclear power

    Over the last few years the nuclear industry has used concerns about climate change to argue for a nuclear revival. Although industry representatives may have convinced some political leaders that this is a good idea, there is little evidence of private capital investing in nuclear plants in competitive electricity markets. The reason is simple: nuclear power is uneconomical. In an excellent ...

  • Underwater Robots Perfect for Power Production

    Underwater exploration, fish farms, dive jobs, marine research, municipal and commercial water utilities are obvious industries for the utilization of Deep Trekker mini-ROVs and pipe crawlers. However another industry that has seen remarkable success integrating underwater inspection robots is energy production. Diverse methods of creating energy provide a number of applications which benefit ...

  • Wind-driven SVE system extracts VOCs from landfill

    An innovative soil vapor extraction (SVE) system has operated at the former Ferdula Landfill site in Frankfort, NY, for the past 10 years. The system relies on wind-driven vacuum processes rather than electrically powered air blowers to extract volatile organic compounds (VOCs) from the landfill. After a two-year trial beginning in 1998, the New York State Department of Environmental Conservation ...

  • 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 ...

  • Negative Power Generation Aspects of Adopting Renewable Sources

    Renewable energy resources are all the rage nowadays on a global scale with the biggest benefit of providing unlimited access without any fear of depletion or running out in the near future. It also provides the edge of saving the continuously decreasing fossil fuel reserves and to protect the planet against the harmful pollution caused by the burning of all non-renewable resources. Some common ...

  • Rising seas and powerful storms threaten global security

    Standing before the United Nations General Assembly in October 1987, Maumoon Abdul Gayoom, President of the Maldives, made an appeal representing “an endangered nation.” That year for the first time, “unusual high waves” in the Indian Ocean inundated a quarter of the urban area on the capital island of Male’, flooded farms, and washed away reclaimed land. Gayoom cited scientific evidence that ...

  • ANFIS and ANN models for the estimation of wind and wave-induced current velocities at Joeutsu-Ogata coast

    In this study, the adaptive network-based fuzzy inference system (ANFIS) and artificial neural network (ANN) were employed to estimate the wind- and wave-induced coastal current velocities. The collected data at the Joeutsu-Ogata coast of the Japan Sea were used to develop the models. In the models, significant wave height, wave period, wind direction, water depth, incident wave angle, and ...

  • The Power of Innovation: meeting our energy challenges through accelerated innovation

    We are facing two urgent energy challenges. We need to maintain modern energy services and expand energy access to another 1.4 billion people.1 We also need to mitigate further climate change by reducing greenhouse gas emissions, including carbon dioxide from fossil fuel burning.2 Low-carbon technologies such as wind and solar power exist and have the technical capacity to meet global energy ...

  • A small island in the Indian Ocean offers big lessons on clean power

    The Indonesian island Sumba is working to provide 100% renewable electricity to all 650,000 residents by 2025. As the sun sets on the small Indonesian island of Sumba, Danga Beru Haba begins weaving under the glow of a single incandescent lightbulb, the only one in her home. Although she is tired from working dawn to dusk in the fields surrounding her village of ...
