1. An electricity generation system wherein multiple modified spark ignition engines are used to power generators whose outputs are combined;
wherein at least one spark ignition engine is fueled with ammonia and/or methanol;
wherein exhaust from the at least one spark ignition engine passes through a three-way catalyst;
wherein the at least one spark ignition engine is a modified automotive engine;
wherein electricity is used in production of the ammonia and/or methanol;
wherein the ammonia and/or methanol that is produced with the use of electricity is stored and is later used to fuel the electricity generation system;
wherein the electricity generation system provides electricity when needed; and
wherein the power produced by electricity generation system is varied by turning engines on and off.
