Two Self Defeating Arguments?

The Sunrush (1993-2017 when solar energy grew exponentially) coupled with the recent INDCs agreed at the COP21 in Paris (2015) have led to mainstreaming of Climate Change and the emissions problem like never before. The main emissions around the globe occur in the transport and the industrial sector, or more specifically the thermal sector using fossil fuels. The search for alternatives has led to initiatives like International Solar Alliance and the concept of Green Economy and LEED of USGBC (US Green Building Council), among others. Here I will attempt to present (and critique) my view about why Hydrogen might be an answer (and why it is important to pursue it seriously), in association with solar, wind and tidal energy. Then I shall veer off into what is perhaps a more ridiculous (and thus incorrect) source at the moment.
