Solar Energy – trends and smart solutions in Sweden

A recently made survey by Solar Region Skåne shows that in Skåne there are 481 solar power plants on-grid which in total produce 6.0 MW Energy. The solar energy production in Sweden are low but the production is increasing. For instance, Värnamo.nu reports that the Diocese of Växjö, Sweden will investigate how many of the buildings owned by the Church of Sweden that are suitable for Solar panel installation. In April the SOM-institute in Sweden published their survey ‘Public opinion on different energy sources 1999-2013’ (available in Swedish) showing that 81 % of the respondent wish to have more solar energy production. In second and third place came wind and wave power. Solar energy is the most popular energy source amongst the respondents in another survey conducted by Svensk Fastighetsförmedling in 2014. 64 % want renewable energy from solar power followed by wind power. 50 % of the respondents wish to be self-sufficient of electricity and only 1 % want fossil-fuel as an energy source for their private homes in the future.

We must take action now if global temperatures are to be limited to a + 2°c increase. The global emissions of Greenhouse gases have to reach its peak in a near future. To achieve Vision 2050 – A vision of Sweden having a sustainable and resource effective energy production with no net-excess of greenhouse gas emissions to the atmosphere – a larger production of renewable energy is required. According to the Swedish Energy Agency and the Swedish Environmental Protection Agency, renewable energy will constitute at least half of the energy production in Sweden by 2020 (more information in Kontrollstation 2015). One of Sweden’s Climate- and Energy Objectives (2020) will therefore be accomplished.

But what about innovative solutions available on the market? Well, to minimize the climate impact it is possible to use wood instead of steal as support system for the solar panels, which is a product offered by InnoVentum. Or why not combine solar and wind power? Hybrid solutions, environmentally friendly materials and multifunctional installations, like combining green roofs with solar panels, are hopefully part of the future. At Augustenborg Botanical Roof Garden there is a small-scale installation of a BioSolar Roof by Svenska NaturTak.

Smart, don’t you think?
