good article but misleading to anyone not from the industry. Unfortunately the power required to run drawworks, pumps and a koomey system is just a tad beyond the capability of solar. So what does that leave on a rig to power.. lights, data acquisition PCs, satellite systems, camps, coffee and ice-cream machines yes no problem, but this has been in place for years!
One BIG point is well control, you need reliable ready to rock n' roll power so from a safety and environmental perspective I wouldnt be relying on anything known to man today other than the ever ready combustion engine, and this alone is the very reason majority of companies reversed their decision to use electric well cementing systems
As far as everything else is concerned around a rig, any drilling company that doesn't meet ISO 9001 & in particular 14001 standards is nothing more than a cheap ass charlie outfit trying to crack the market
I bet my bottom dollar they're not equiped to utilise recyclable drilling mud... thats been around for years too
As Donald Trump would say... fake news!
