Integrated Systems to Reduce Global Warming

A future of renewable energy as a primary source for the world’s energy society can no longer be ignored. As fossil fuel supplies diminish and the cost of atomic energy continues to rise, while there is no safe and well-documented solution to the deposition of nuclear waste, renewable energy can step in to provide feasible alternatives to energy demands. Renewables do pose significant challenges especially in addressing the fluctuating power supply that is inherent in their nature. Robust, integrated solutions using available, mature technologies have proven to be the solution to the challenges that wind and solar energy causes. Denmark has in the past and continues to be a leader in integrated renewable energy solutions. By 2014, Denmark with its 5.65 million inhabitants still was on the world top 10 list measured by accumulated wind power capacity; 39 % of the electricity came from the wind. In particular, the use of combined heat and power systems and the implementation of district heating have proven successful for Denmark and can be transferred elsewhere. This chapter seeks to explore questions surrounding the implementation of sustainable integrated solutions very concretely in relation to energy in general and renewable energy in particular.
