 FPGAs are extremely important to  
avoid a massive Climate Desaster

By far most CO2 emission worldwide is caused by electricity generation. A major part of electricity consumption is caused by computers: millions of huge data stations not only to run the internet, embedded computer systens everywhere, billions of PCs and zillions of all kinds of other portable devices [1]. Worldwide the electricity consumption is increasing at very high speed. More than the 40 largest powerstations would be needed just only to run the internet [ZDF, Sep. 23, 2018]. If the internet would be a country it would have the sixth largest electricity consumption on our planet. The still dominant (three quarter centuries old) ancient Computer Paradigm is extremely energy-inefficient: the von Neumann syndrome. Click here.

Already two decades ago by several orders of magnitude better energy efficienciy have been demonstrated by migrations to the Xputer Paradigm based on FPGA usage [2] [3] (or, even by several more orders of magnitude better energy efficiency on the DPLA).

More than 5000 conference series or workshop series have at least some relations to FPGAs [4]. However, FPGAs are tabooed by the media, so that politicians do not know this way to cope with the climate desaster. I am looking for talented journalists being ready to solve this problem.
