NOVELTY - Method (I) for recycling carbon-containing gas emissions (which has been captured and sequestered in an underground or undersea storage area), comprises: (a) withdrawing the gas from the storage area after sequestration or storage in it; and (b) converting the gas to carbon-containing compounds to provide a renewable energy source.    USE - The methods are useful for: recycling carbon-containing gas emissions; controlling, neutralizing or decreasing the human carbon footprint of an entity; producing renewed carbon-containing compounds, which are carbon-containing fuels or synthetic hydrocarbons, including methanol, dimethyl ether (which is used as a substitute for diesel fuel, natural gas or liquefied petroleum gas for household heating), or products derived from them (ethylene and propylene, which are further converted for use as feedstocks for chemicals or as transportation fuels), and ethanol, propanol or isopropanol (all claimed); and generating electricity.    ADVANTAGE - The methods: avoid any unintended escape of the gas from the storage area; captures and recycles greater amount of carbon dioxide directly from the atmosphere, thus providing a feasible, economic and safe way to mitigate the environmentally harmful effects of carbon dioxide; provide a safe, environmentally adoptable renewable energy source; provide an efficient and permanent way to control, neutralize or reduce carbon footprints without limiting or prohibiting the use of carbon-containing fuels, materials or products that leave carbon footprints; and provide a means for efficient storage of energy, including electricity on a large scale.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) method (II) for controlling, neutralizing or decreasing the human carbon footprint of an entity, comprising capturing and sequestering the carbon containing gas the an underground or undersea storage area, and the steps (a) and (b) as above per se; and    (2) method (III) for producing methanol from a feed gas of carbon dioxide, methane, natural gas or a hydrocarbon homolog of them, comprising obtaining the feed gas from a sequestered supply in the underground or undersea storage area to convert it into carbon-containing compounds to provide a renewable energy source.
