The global energy demand has increased nearly exponentially in the last century and is projected to increase at a similar rate in the future. Yet the finite qualities of fossil fuels and CO2 emissions make many non-renewable energy sources (including coal, natural gas, and oil) unreliable in fulfilling the global energy demands.
