The potential for CutPower is huge.
In Germany. And in Europe.
According to a Prognos study published in 2011, potential savings realizable by CutPower up to the year 2020 total 233 Terawatt hours (TWh) in Germany alone; one TWh is 1 million megawatt hours (MWh). The study estimates the required volume of investment at 135 billion euros; adjusted for the transportation sector this represents economic potential of almost 150 TWh. That enormous amount of energy is approximately equivalent to all electrical power generated using brown coal (lignite) plus all renewable energy generated in the first half of 2014* in Germany; it exceeds total annual electricity production using hard coal and is equivalent to the annual output of more than 12 large-scale power plants.
A Siemens study conducted in 2013 sees realizable CutPower potential of 79 TWh in the industrial sector alone, with annual savings of 4.4 billion euros; to realize those savings, investments of roughly 13 billion euros must be made.
Energy consumption in Germany showed growth in 2013 to roughly 14,000 Peta-Joules (PJ)*, which is the equivalent of approximately 3,900 TWh. At market prices, the cost of that power was approx. 1 trillion euros (= 1,000 billion euros). The building sector alone accounted for approx. 40% of consumption, or 400 billion euros per year; and with a latent existing savings reserve of at least 30% the savings which can be realized by CutPower exceed 100 billion euros annually.
