Fuel Alternatives Generates More Carbon Dioxide

US scientists called for a major investment into research and development of alternative energy sources.

The scientists evaluated possible future energy sources, including wind and solar power, nuclear fission and nuclear fusion that do not produce carbon dioxide.

The energy alternatives were evaluated for the ability to supply mass amounts of carbon-emission-free energy and their potential for large-scale commercialization.

The American scientists eyed on several promising technologies, but none presently are suitable for use and need further developments and of course broad investments.

The main disadvantage of all current technologies is that replacing combustion engines with fuel cell engines may cut carbon dioxide emissions from vehicles, but producing the hydrogen required to power fuel cells actually generates more carbon dioxide emissions than the combustion engines would create.
