A major factor of global warming is CO2 emission, which is caused by the burning of fossil fuels. NTS has developed an energy producing system that will satisfy the requirements of 30,000 households (US market) or 70,000 people.
With the application of a 120 GWh power plant using our technology, each NTS crosswind system would avoid the emission of 102,720 tons of CO2, 108.9 tons SO2 equivalent, 68.3 tons Nox, and 3312 tons dust and fuel ash. (source: contaminant calculation by the Federal Association for Wind Energy).
With the global increase in energy demands also come growing demands and challenges made on environmental protection by the energy producers.
Yet adherence to legal provisions and commitment to environmentally conscious conduct alone does not get us there. Creating the parameters that ensure optimal consideration of environmental aspects is equally important. Hence NTS has integrated a sustainability and environmental management framework into its business concept. The Company’s credo proclaims the clear intentions of NTS to integrate climate and environmental protection as key strategic tasks into its business endeavours. Annual audits will ensure that we continually review and improve our processes.

In order to reach the 2°C target it will ultimately be required to curtail all further greenhouse emission by between 2015 and 2020 at the latest and then continue to reduce them by a further 50% to reach 1990 levels by 2050.
For a fair load distribution greenhouse emissions in industrial countries must be reduced by 80% by 2050 to reach 1990 levels in order to effectively contribute to the global reduction of CO2 and equivalents to an average of 50% of 1990 levels.
Global climate change during the last 100 years
A middle impact scenario estimates a global rise in temperatures of between 1.8°C (+/- 1.1-2.9) and 4°C (+/- 2.4-6.4).
If greenhouse emissions are not reduced and stabilized, the targeted 0.2°C rise over the next 30 years is highly unlikely.
Even with a stabilization of CO2 concentration by 2100, climate change will continue to occur throughout the 21st Century and sea levels will also continue to rise.
A low impact scenario stipulates a rise in sea levels of between 18cm and 38cm and a high impact scenarios demonstrates a rise of between 26cm and 59cm. These scenarios, however, have not yet considered polar ice dynamics and the uncertainties confronting the carbon feedback cycle. Meteorological extremes are expected to occur during the 21st Century with increasing intensity and frequency.
Environmental impact statements on regional climatic changes are more difficult to predict and remain uncertain.
According to the scenario studies the fundamental climate changes prognozed for Europe include:
A mean rise in temperature of 2 – 6.6°C from 1990 to 2100 with the highest increases expected in Southern Europe (Spain, Italy, Greece) and North Eastern Europe (Finland and Western Russia);
Increasing frequency of hot summers especially in Southern Europe;
Winter periods will continue to warm up faster than summer periods except for Southern Europe;
A broad increase in rainfall of 1-2% per decade in North Eastern Europe with a possibly simultaneous decrease in rainfall in Southern Europe by up to 1% per decade. During summer the climate differences between Northern and Southern Europe are distinctively visible (North Eastern Europe: up to 2% per decade, Southern Europe: up to –5% per decade).
For Germany, the regional climate models of the UBA (Umweltbundesamt) are used to estimate the likelihood of climate change. The following eventualities can be deduced for climate development in Germany by 2100:
A rise in temperatures is highly likely. According to calculations from the different scenarios compared to levels recorded between 1961 and 1990 temperatures will rise 2-3% by 2100.
The simulations indicate only minor changes in annual rainfall, though “rainfall during summer periods are likely to decrease significantly”
Unfortunately, many people are still convinced that “a little warmer will do no harm.” What is even more unfortunate is that people don’t understand that warmer means more intense.
It is not just a matter of arctic ice melting and vast land masses virtually “sinking”.
A much more disturbing factor is the expected fluctuation in atmospheric temperature. The higher the temperature fluctuations the more severe wind storms will be in order to equilibriate temperatures between the equator and the arctic poles. According to statistics from Proclim the intensity of turbulent storms between 1950 and 2000 has more than doubled from approximately 0.4 - >0.8 based on the PDI (Power Dissipation Index).
It is not just the intensity we should worry about but also the frequency. Statistically, the mean number storms has risen by 500% between 1970 and 2006 ( refer diagram. Source: UBA ).
All that may still leave some people unmoved but lets consider the costs. Statistics from Allianz (source: http://www.bcm-news.de/wp-content/uploads/allianz-rising-costs-of-disaster.jpg) indicate that the costs of environmental catastrophes, which we are all liable for, have risen by 1500% since 1970 from approximately 2 billion Euros to approximately 30 billion Euros in 2010 and are expected to be 40 billion Euros in 2019.
