It has been a dream for many to use solar energy for heating and hot tap water. So far, the only problem has been that it is expensive to install devices to catch solar energy. At individual buildings it is normally very expensive and therefore not yet a sustainable solution. Continue reading “Solar energy – a dream comes true”
At www.energymap.dk you can visit many interesting energy cases on a virtual tour. You are welcome to visit our profile http://www.energymap.dk/Profiles/Ramboll to study our urban energy solutions, cases and projects. Once you have decided what you would like to study in detail, you may consider to come to Denmark and see it real.
It is a political priority that our new buildings and our new city districts shall be sustainable. But how do we find the most sustainable energy solutions? We have an approach and an answer. Continue reading “How can we measure sustainability?”
Mother Earth is running short of fossil fuels, and climate change is a threat to human civilisation. At the same time the population grows, and people move to the cities. This is a challenge, but also an opportunity.
The Danish Government presented its “Energy Strategy 2050”, February 2011. The plan describes how Denmark can be independent from coal, oil and gas by 2050.
The strategy contains a first phase of initiatives that will reduce the use of fossil fuels by 33 percent in 2020, compared with 2009.
“Denmark is the first country to present such a specific and ambitious strategy for achieving independence from fossil fuels,” says Minister for Climate and Energy Lykke Friis.
The strategy is the first political step to implement the recommendations of “Green Energy, The road to a Danish energy system without fossil fuels“ – a comprehensive study submitted by the Danish Climate Commission, September 2010. It is available in English and Chinese.
The Energy strategy focuses on the most cost effective and sustainable energy solutions, which can be implemented right now based on the existing technology – not lease the urban energy infrastructure.
Thereby, Denmark can be the first EU country to implement the EU Energy Efficiency strategy and demonstrate the benefits of “smart cities” and “intelligent grids for electricity, district heating and district cooling”
The more difficult solutions, e.g. how to develop “green traffic”, are not yet commercial but will follow in the coming decades.
In the coming months, I will like to share my experience with you about these challenges and opportunities at this blog.
I sincerely hope many of you, dear readers, will share knowledge with me and spread the ideas.
