Products such as milk and cheese are not the only yield produced from cows in California. Methane is also a byproduct of cows. Since methane gas has 20 times the potential than carbon dioxide as a greenhouse gas, we must capture this gas instead of releasing it into the atmosphere. We can use this methane gas to fire up generators and produce electricity. This is being done on California dairy farms with the use of methane digesters breaking down cow manure. In the thriller novel, Green Power
, set in California this is exactly what the protagonist does. However, when an epidemic breaks out pointing to the methane digesters as the cause, the safety of this alternate source of energy is questioned. What other novels fit into the new genre of environmental thrillers?
