Renewable
Energy (Continued)
zFuel combustion
produces “greenhouse gases” that are believed to lead to climate change (global warming), thus combustion
of biomass is not as
desirable as other forms
zBiomass combustion is
also renewable, but emits CO2 and pollutants
yBiomass can be heated with water under pressure to create synthetic fuel gas; but burning biomass creates
pollution and CO2
zNonrenewable energy
comes from fossil fuels and nuclear radioactivity
(process of fossilization still occurring but trivial)
yNuclear energy is not
renewable, but sometimes is treated as though it were because of the long depletion period
