At the AlwaysOn GoingGreen conference in Sausalito, Calif., Tim Vail of Synthesis Energy says a mix of solutions is needed to solve our energy problems. Erik Straser of Mohr Davidow Ventures adds that although we do have natural resources still available to us, new technologies are needed to extract them in a cleaner, greener way.
Can coal be clean?

Clean coal, no it still gets my hands dirty. Not funny. The combustion of any carbon containing fuel produces among other things CO2. While it may be too late I think we should try to reduce our CO2 production from ancient storage in the ground as much as possible. No matter how we burn coal or use it to produce other hydrocarbon fuels the result is the same, more CO2 into the atmosphere. Sequestered CO2 while possible costs more than non carbon energy sources. We overlook nuclear energy because of a few accidents, not accidents but criminal action by the operators and builders of the nuclear power plant. The nuclear power plants in the U.S.A. are inefficient outmoded and often poorly built. The so called waste is recyclable usable isotopes. The design only uses about 5% of the energy in the uranium fuel. There are new designs that can use 95% of that energy. To be useful solar, wind, wave, tidal energy need a storage system to provide 24/7 energy supply. Major dam systems could be used for this storage. the generating equipment is already in place. Just add the pipe lines and pumping equipment and then solar and it's byproducts, wind etc, would become a real usable energy source.
