• 100% renewable energy sources require overcapacity

    Germany decided to go nuclear-free by 2022. A CO2-emission-free electricity supply system based on intermittent sources, such as wind and solar - or photovoltaic (PV) - power could replace nuclear power. However, these sources depend on the weather conditions.

    In a new study published in EPJ Plus, Fritz Wagner from the Max Planck Institute for Plasma Physics in Germany analysed weather conditions using 2010, 2012, 2013 and 2015 data derived from the electricity supply system itself, instead of relying on meteorological data.

  • IKEA Canada to purchase second wind farm in Alberta

    Burlington, ON – IKEA Canada has signed agreements to acquire an 88MW wind farm located near Drumheller, Alberta approximately 130km east of Calgary. Consisting of 55 turbines, the Wintering Hills wind farm will generate 275 million kWh (kilowatt hours) of energy, the equivalent to the electricity consumption of 54 IKEA stores or nearly 26,000 Canadian households.

  • Nordic countries are bringing about an energy transition worth copying

    What can we learn from the Nordic low-carbon energy transition given the new US leadership vacuum on climate change? A new study by Professor Benjamin Sovacool at the University of Sussex offers some important lessons.

    The Trump administration's "First energy plan" criticises the "burdensome" regulations on the energy industry and aims to eliminate "harmful and unnecessary policies such as the Climate Action Plan" which was introduced by President Barack Obama. It has also deleted all mentions of climate change and global warming from the White House website.

  • Decarbonising the UK economy

    This week the UK Government published its long awaited industrial strategy, marking a distinctive break from the previous Conservative regime. Gone is David Cameron's more laissez faire attitude to managing the economy.  In its place is a more proactive approach, which seeks to stimulate industry with targeted investment.  Taking advantage of the greater flexibility afforded by freedom from the EU's state aid rules the plan sees some exciting developments in the decarbonisation of the UK economy.

  • Northwestern Cuts Energy Use in the Battle of the Buildings

    From September 1 through November 30, 2016, Northwestern competed in the U.S. EPA ENERGY STAR's Battle of the Buildings, a national competition to reduce energy use in buildings. The top performer among the University’s competing buildings was the Tarry Research and Education Building. Over the course of the competition, the building saved more than 228,000 kWh of electricity. This is equivalent to the total annual energy usage of 17 average homes.

    Northwestern entered five buildings in the competition: the Tarry Research and Education Building, Catalysis Center, 1801 Maple, the Technological Institute, and Cook Hall. These buildings all contain laboratory spaces, which tend to be extremely energy intensive. During the competition, sustainNU worked with building managers, lab managers and users, and the Office of Research Safety to conserve energy while maintaining safe lab procedures.

  • Targeting Cookstove Pollution Using Supercomputers and NASA Satellites

    New air quality research is investigating a major, but often overlooked contributor to outdoor pollution and climate: burning of solid fuel for cooking and heating.

    Cookstove studies typically evaluate how they contribute to indoor air quality issues in houses where solid fuel is frequently used for cooking and heating. A new paper from the University of Colorado Boulder appearing in the Proceedings of the National Academy of Sciences, has taken a different approach, going outside the home and evaluating how cookstoves impact ambient air pollution and climate.

  • Obama's clean energy legacy - how long can it last?

    President Trump comes into office determined to discard huge swathes of his predecessor's legacy on day one, writes Mark Barteau. But he will struggle to undo Obama's clean energy regulations. It's not just that they are legally robust, it's also that energy markets in the US and the wider world have shifted firmly, and irreversibly, towards efficiency and renewables. Sorry, Mr Trump.

  • New Study Will Help Find the Best Locations for Thermal Power Stations in Iceland

    A new research article, with lead authors from the University of Gothenburg, gives indications of the best places in Iceland to build thermal power stations.

    In Iceland, heat is extracted for use in power plants directly from the ground in volcanic areas. Constructing a geothermal power station near a volcano can be beneficial, since Earth’s mantle is located relatively close to the crust in those areas, making the heat easily accessible. This means that the boreholes do not need to be very deep and the pipes to the power plant can be short.

  • Extreme Space Weather-Induced Electricity Blackouts Could Cost U.S. More Than $40 Billion Daily

    New study finds more than half the loss occurs outside the blackout zone.

    The daily U.S. economic cost from solar storm-induced electricity blackouts could be in the tens of billions of dollars, with more than half the loss from indirect costs outside the blackout zone, according to a new study.
