    Sweden: Pioneer of solar district heating

    When it comes to district heating, Sweden has made the switch from fossil fuels to biomass and waste heat (see chart). As early as 2015, biomass provided 46 % of the energy in district heating networks across the country, followed by 24 % from waste incineration and 8 % from industrial...

    Solar thermal and biomass – a winning solution for district heating

    Biomass may be cheap and carbon-neutral, but a solar upgrade of biomass-fired district heating could further improve efficiency and reduce local emissions. For example, solar heat helps avoid having to start up and shut down wood-chip boilers or operate them at partial load. It can even...

    SHC 2017 / Maria Wall: Solar Energy in Urban Planning

    In ancient Rome, urban citizens had a "right to light" that was limiting the densification of cities to get sufficient daylight and also natural ventilation. With electric lighting and mechanical ventilation, this got forgotten. Maria Wall explains why the increasing use of solar energy and...

    IEA SHC Solar Academy: Solar Planning in Times of Rapid City Growth

    Just as on Stockholm’s coastline shown in the photo, cities are seeing new neighbourhoods develop or old ones restored and expanded at a rapid pace. Urban planning is a highly complex issue, especially if it involves low-carbon living solutions and environmental regulations. The main...

    Solar Thermal Shows Highest Energy Yield Per Square Metre

    The annual energy yield per square metre is much higher for solar collectors than for other renewable technologies, as the figure on the left shows. Compared to PV, solar collectors produce, on average, three times as many kilowatt-hours. Compared to biomass or bioethanol, output is in...
