One source of fuel hydrocarbons in the 19th century was the whaling industry. I guess that won’t work in the 21st century.
According to industry website SaveTheWhales.org, a sperm whale could produce 2000 gallons, or 47.6 barrels, of oil. Thus a touch of long division tells us that we will need to slaughter approximately 630 million sperm whales each year in order to completely replace our petroleum production. Since there are only an estimated one million sperm whales currently living on Earth, wiping out the entire species would power the global economy for about half a day.
Too bad. I wonder how much oil we could squeeze out of puppy dogs and bunny rabbits?
