The authors are moving to a new cellebrum - the era of \"E\" which belongs to computers, electronics and its energy issues. Looking back to previous years, work done was manual that involves the analytical and statistical efforts of human mind. Moving down to the 21st century, the arm of the head has changed its position to \"Technology\", reducing the mind analysis of humans and better optimal decisions and computations as its main outcomes. Energy issues will get a serious ring in the coming days, as the public debate on carbon emissions, global warming and climate change gets hotter.
