“…It has been pointed out that an energy system is sustainable if it complies with the following criteria [7][8]：(a) the Energy Ratio, calculated as the energy source output divided by the energy source input, is higher than one; (b) the marginal increase in the energy source input produces proportional or more than proportional marginal increase in the energy output; (c) no negative externalities are incurred by the use of such energy source, or such externalities are more than sufficiently compensated.…”

“…hydroelectric and geothermal energies, biomass, wind energy, photovoltaic and solar thermal energies. The production of hydrogen must avoid using fossil fuels or traditional nuclear energy technology in order to fulfil the third Moriarty-Honnery criterion discussed above [7][8]. Therefore, the remaining third source is the only option with the potential to construct a truly sustainable energy system.…”

Abstract. In the 21st century, ever increasing energy and environmental problems such as pollution, fossil fuel depletion and global warming are ringing the alarm bell to human society. Therefore, clean and renewable energy materials as well as their devices are urgently demanded. In this paper, we first give the definition of environmental sustainability, then the forms of energy sources and its sustainability and environmental impact are discussed. Finally, the main characteristics of hydrogen storage as well as carbon materials and solar energy materials are expounded.

“…The world economy is mainly based on the exploitation of fossil fuels (oil, coal and methane) (Moriarty 2007), according to data provided by International Energy Agency reported in Figure 13. In particular, the primary energy source is oil, but owing to the decrease of its reserves and to Gallucci, F., Basile, A. and Hai, F. I.…”

“…Moriarty and Honnery (2007) note that solar power is presently the most expensive of the renewable alternatives, although photovoltaic (PV) technology appears close to significant breakthroughs (Morton, 2006). It may be in fact that the necessary technology has already been developed in the form of a new process for large-scale production of silicon for solar panels at significantly reduced cost (PureEnergySystems, 2007).…”

“…Carbon-neutral hydrogen production might be achieved at some greater expense by sequestration of by-product carbon dioxide, or by using nuclear power to create hydrogen from electrolysis of water (Yamawaki and others, 2007). However, a sustainable hydrogen economy can only be achieved if the hydrogen is created entirely from renewable energy sources (Nowotny and Sheppard, 2007;Moriarty and Honnery, 2007).…”

A sustainable global silicon energy economy is proposed as a potential alternative to the hydrogen economy. This first visualisation of a silicon energy economy is based on largescale and carbon-neutral metallic silicon production from major smelters in North Africa and elsewhere, supplied by desert silica sand and electricity from extensive solar generating systems. The resulting "fuel silicon" is shipped around the world to emissionfree silicon power stations for either immediate electricity generation or stockpiling. The high energy density of silicon and its stable storage make it an ideal material for maintaining national economic functioning through security of base load power supply from a renewable source. This contrasts with the present situation of fossil fuel usage with its associated global warming and geopolitical supply uncertainties. Critical technological requirements for the silicon economy are carbon-neutral silicon production and the development of efficient silicon-fired power stations capable of high-temperature rapid oxidation of fuel silicon. A call is made for the development of research effort into these specific engineering issues, and also with respect to large-scale economical solar power generation.
