Energy Management (EM) has become crucial and much more complicated for airports with the introduction of various energy sources, technologies and different comfort requirements.
It is produced as a direct result of choices we make, both individually and collectively, about energy sources, technologies, economic activities, and lifestyles.
This pushes forward the limits of alternative energy sources technology and, particularly, the technology of light-harvesting devices.
Last March, President Obama said that new energy sources and technologies would make America "less dependent on what's going on in the Middle East".
"Developing new energy sources and technologies is an important part of our all-of-the-above approach, but it is clear that this loan guarantee program is ineffective at best, and counterproductive at worst".
And there is a huge amount we can learn from our own past and ability to engineer rapid change, whether the uptake of new energy sources and technologies, the building of transport infrastructures and cities, or new social contracts to guarantee the health, education, freedom and rights of populations.
President Obama has made scientific innovation the cornerstone of his plans for "winning the future," requesting in his recent budget proposal large financing increases for scientific research and education and, in particular, sustained attention to developing alternative energy sources and technologies.
Evolution from fossil fuel energy to renewable energy sources and technologies is in the spotlight towards an accelerated energy transition process.
The Fukushima accident has influenced public attitudes toward energy sources and technologies, including not only nuclear energy, but also other energy sources.
Meeting these targets is a challenge that calls for innovative research to improve the use of renewable energy sources, new technologies, and holistic tools and methodologies.
Investment into clean energy systems can also be viewed as an investment into energy sources and technologies that are significantly less environmentally damaging than in the status quo case.
