Didn’t need a researched article to figure this one out. For years, I compared my electric bill to my gas bill.
Then one day, the legendary Dr. Bill Wattenberg out of 5000 watt radio station KGO stated the obvious, that we have abundant natural gas in California and switching to natural gas powered buses would save a bundle.
Of course, that was before Donald Trump lifted the totalitarian hand of Amerika off the backs of producers of oil and America became the top producer of oil in the world! Still, abundance of any form of energy is desirable in a free country.
KGO runs 50KW (daytime) and 5KW at night.
