A recent experiment sponsored by the Germany government intends to show that a network with 61 percent of electricity from wind, 14 percent from solar photovoltaics, and 25 percent from biomass, can meet up to 100 percent of electricity demand Renewed Energy, The Guardian, February 26, 2008, But as discussed below, biomass is very problematic and could emit more greenhouse gases than fossil fuels. Thus, the experiment suggests a 75 percent limit to de-carbonization of electricity generation

Although there has been much talk of developing a hydrogen economy, hydrogen itself is not a primary energy source (i.e, there are no natural stores of hydrogen to be exploited, Hydrogen fuel is produced from water, a process which requires energy input. Thus, hydrogen is simply an energy storage mechanism much like a battery, and its environmental consequences depend on the source of energy that is used to produce it

Although there has been much talk of developing a "hydrogen economy," hydrogen itself is not a primary energy source (i.e., there are no natural stores of hydrogen to be exploited). Hydrogen fuel is produced from water, a process which requires energy input. Thus, hydrogen is simply an energy storage mechanism (much like a battery), and its environmental consequences depend on the source of energy that is used to produce it.
