Renewable energy: Denmark as a case study
Efficiency altercations and power efficiency had been a very crucial part of the policy pertaining to energy since the unfortunate oil crisis in 1973
Within a period of more than a decade, Denmark has been able to sustain and retain its fuel consumption, whilst radically improving its transportation consumption.
Mtoe = 11.63 TWh. Primary energy includes energy losses.

It can be viewed clearly from the above table that the percentage of CO2level had dropped since 2004 with an increasing dependability on renewable energy as a primary source.
Employing the Energy PLAN energy system analysis model
The preliminary point for the study is the crucial assumption that sustainable development encompasses three technological changes, specifically energy savings towards demand, improvements in the competence of energy production, and replacement of fossil fuels by various sources of renewable energy. Thus, three following technological changes have been recognized for the study.
The demand of electricity, heating demand and district heating has witnessed a 10% drop
Implementation of the emerging fuel-cell technology or by improving the existing steam operated turbine technology. This is characterized by an electrical and heat output of 50% and 40% respectively.
Renewable energy sources
Introduction and increase of input form biomass fuels, solar thermal and photovoltaic to their respective supply, i.e. solar thermal to district heating and photovoltaic to electricity.
The use of flexible technology should also be considered as there has to be integration between all systems involved.
The obvious replacement of oil as a source for transportation towards electrical empowerment.
Flexible combined heat and power systems.
Addition of both wind regulations and Electrolyses
The chart below shows the tendency in fuel consumption which tends to rise rather than fall also it could be identified that electricity production substantially increases with greater combined heat and power systems less demands
It could also be seen that deceased fossil fuels brew an increased excess production which suggests a potential advantage of the use of renewable energy in the economy as a replacement for of fossil fuels
