MacOS Sierra - kernel_task taking very high cpu

Hi Folks,

Since this morning I observed extreme slowness in my MBP. I did not install any new program recently or upgraded OS. Upon checking cpu usage found that kernel_task is taking very high cpu between 200%-800%.

I restarted MBP but no luck yet. This slowness is going on since now more than 5 hours and everything is opening and responding slow in MBP. I also ran EtreCheck and below is the summary. Can Someone suggest what is the cause and how to solve this problem.

EtreCheck version: 3.4.6 (460)
