The Hidden Backbone of the Liveable City

  Imagine you are standing on a green roof top. You can-not see, hear or smell any sign indicating how the energy is generated and what happens to waste water and waste. Only in the distance you notice some activity in an industrial area. In the farm land there is no landfills, no poluted rivers and no power plants. Instead the farmers produce surplus

The “Triple E” container ship A few weeks ago Maersk presented the world’s largest ship to the public in Copenhagen. This very impressive container ship, which can load 18,000 containers, is of the “Triple E” class. Triple E stands for Economy of scale, Energy efficiency and Environmental improvement. According to Maersk, the CO2 emission of transporting 18,000

What makes solar energy cost effective

Marstal district heating

The sun it the most reliable renewable energy source we have, but how can we use it in a cost effective way ?? And what is solar energy ?? and is solar energy cost effective ??  When you google or read about solar energy it seems that the majority agree, that solar energy is coming from solar panels or solar PV

Aarhus and Copenhagen – Energy Efficiency Landmarks for Europe

Heat-plan-Aarhus

The EU directives for Energy Efficiency and Renewable Energy request all regional and local authorities to integrate district heating and cooling into the urban planning. Moreover the Energy Efficiency directives request that new power capacity should be located neat market, which can utilize the surplus heat and reduce cooling losses. This is a challenging “hen

2012 a remarkable year for European Energy Efficiency

IMG_5698 resized

All EU countries can benefit from 35 years of Danish experience to implement the new EU energy directive from 2012, and in 2012 Denmark started a new road map toward CO2 neutral heat and power in 2035. I can see two reasons that year 2012 was a turning point in European efficiency towards a more sustainable

Smart Energy Cities

CPH-districtheating_610

The world population is increasing and has now exceeded 7.000.000.000 people. The need for good indoor climate and hot sanitary water is increasing even more.   Unfortunately, the world will run short of fossil fuels within a few generations, and we have to reduce climate gas emissions due to the risk of climate change –

Smart Cities have Smart Backyards

A view from the city centre to Amager and Amagerforbrænding

Local politicians and urban planners know about the NIMBY (Not In MY Backyard) Syndrome: Everybody wants to benefit from efficient urban infrastructure, such as waste water treatment, waste treatment, and Combined Heat and Power production (CHP). Nobody wants to see, smell or listen to the plants, which are vital for these services. They should be

European Energy Efficiency legislation adopts 35 years of Danish experience.

Avedøre multi fuel CHP Plant

A cornerstone in the coming EU Energy Efficiency Directive is to develop the district heating based on Combined Heat and Power (CHP). Local authorities shall develop heat plans and power companies shall install new power capacity with CHP near heat markets. This is what we have been doing in Denmark with great success since 1980. Ramboll has taken part in

Off shore wind farms – an urban energy solution ?

Off shore wind farms

Can off shore wind farms be an urban energy solution ? and what has the Island Samsø and Copenhagen in common ? The Island Samsø is the first Island in Denmark to be net independent of fossil fuels (on annual basis) – and hundreds of energy experts from all over the world have travelled to
