The present invention invention provides methods, apparatus, and systems for determining greenhouse gas (including carbon dioxide) emissions and energy usage, costs and savings of individuals, families, homes, buildings, businesses, or the like. User inputs specific to an end user are accepted, and one or more of the user inputs are correlated with at least one of historic data and modeled characteristics pertaining to greenhouse gas emissions and energy usage to obtain at least one of greenhouse gas emissions and energy usage corresponding to said one or more of said user inputs. An overall greenhouse gas emissions and energy usage can then be determined for the end user based on the greenhouse emissions and energy usage corresponding to the one or more of the user inputs. A specific impact of a particular user action on the end user's overall greenhouse gas emissions and energy usage may also be calculated.

Diatomic hydrogen and unsaturated hydrocarbons are produced as reactor gases in a fast quench reactor. During the fast quench, the unsaturated hydrocarbons are further decomposed by reheating the reactor gases. More diatomic hydrogen is produced, along with elemental carbon. Other gas may be added at different stages in the process to form a desired end product and prevent back reactions. The product is a substantially clean-burning hydrogen fuel that leaves no greenhouse gas emissions, and elemental carbon that may be used in powder form as a commodity for several processes.

The process and system of the invention converts carbonaceous feedstock such as coal, hydrocarbon oil, natural gas, petroleum coke, oil shale, carbonaceous-containing waste oil, carbonaceous-containing medical waste, carbonaceous-containing military waste, carbonaceous-containing industrial waste, carbonaceous-containing medical waste, carbonaceous-containing sewage sludge and municipal solid waste, carbonaceous-containing agricultural waste, carbonaceous-containing biomass, biological and biochemical waste, and mixtures thereof into electrical energy without the production of unwanted greenhouse emissions. The process and system uses a combination of a gasifier, e.g., a kiln, operating in the exit range of at least 700° to about 1600° C. (1300-2900° F.) to convert the carbonaceous feedstock and a greenhouse gas stream into a synthesis gas comprising mostly carbon monoxide and hydrogen without the need for expensive catalysts and or high pressure operations. One portion of the synthesis gas from the gasifier becomes electrochemically oxidized in an electricity-producing fuel cell into an exit gas comprising carbon dioxide and water. The latter is recycled back to the gasifier after a portion of water is condensed out. The second portion of the synthesis gas from the gasifier is converted into useful hydrocarbon products.

A carbon credit is a generic term for any tradable certificate or permit representing the right to emit one ton of carbon dioxide or the mass of another greenhouse gas with a carbon dioxide equivalent (tCO2e) equivalent to one ton of carbon dioxide.

Carbon credits and carbon markets are a component of national and international attempts to mitigate the growth in concentrations of greenhouse gases (GHGs). One carbon credit is equal to one ton of carbon dioxide, or in some markets, carbon dioxide equivalent gases. Carbon trading is an application of an emissions trading approach. Greenhouse gas emissions are capped and then markets are used to allocate the emissions among the group of regulated sources.

Carbon credits can be generated by any process that conforms to ISO 14064-66 standards. Once generated, carbon credits can be stored in a distributed, Cloud-based ledger. The ledger entries can serve as a registry for carbon credits as well as the data source for an Internet-enabled trading system or financial exchange that allows the carbon credits to be sold and bought as part of the same system. The distributed ledger can provide records that combine the details of the carbon credits' origin, transaction history, and financial instructions associated with trading of the carbon credits via a distributed ledger system.

Heating is a significant factor in residential gas-energy usage. Saving energy on heating is receiving increasing attention with rising energy prices and the Kyoto Protocol on reducing greenhouse gas emissions. Energy awareness and energy efficiency hereby become important qualifications for human behavior and residential building codes, and become a factor in the evolution of the global climate. Here, we describe a novel measurement and validation system for domestic gas-energy usage in combination with primary weather data. We disclose a gas-energy observatory which visualizes human behavior in gas-energy consumption associated with domestic facilities, and measures home energy efficiency by calorimetry. Weather-sensitivity analysis quantifies energy-usage as a function of small variations in room temperature and home energy efficiency. Weather-sensitivity data can be used to calculate changes in room-temperature settings or improvements in home insulation for a desired reduction in CO₂-output. By public dissemination of its primary weather data, it creates in dual-use at no additional cost a novel in-situ climate observational systems with unprecedented wide-area coverage and spatial resolution.

The invention discloses a comprehensive utilization method for rice hull combustion emissions and waste residue, in particular a method for preparing superfine silicon dioxide and active carbon with high specific surface area by using the emissions and waste residue generated by the pyrolysis and combustion of the rice hull, which comprises the following steps: the main raw material sodium carbonate (or potassium carbonate) is heated and hydrolyzed to be sodium bicarbonate (or potassium bicarbonate), OH<-> is released, the silicon dioxide in the rice hull ashes is dissolved, the sodium bicarbonate (or the potassium bicarbonate) is reduced to sodium carbonate (or potassium carbonate) after temperature reduction, and then the silicon dioxide precipitate is separated out. The method has the advantages that the silicon dioxide which only plays the role of catalyst in the process can be used circularly without consumption, the cost is reduced; the purified combusted tail gas can be used for preparing a precipitator of the silicon dioxide, thus avoiding the pollution brought by acid neutralization and precipitation in the traditional technology, reducing the cost, making full use of carbon dioxide and reducing green house gas emission; and the activating agent for preparing the active carbon can be recovered, which can be returned to the hydrolyzation process to be reused after adjusting the concentration of the sodium carbonate (or the potassium carbonate), thus reducing the cost.

Wallboards, as well as cement boards, are produced by methods which use significantly reduced Embodied Energy when compared with the energy used to fabricate gypsum wallboard. A novel binder, consisting in one embodiment of phosphoric acid and calcium silicate, and combined with various fillers, is used to provide a controlled exothermic reaction to create a gypsum-board-like core which can be wrapped in a selected material such as recycled paper and manufactured on a conveyor system to appear and handle like gypsum wallboard, but without the large amounts of energy required to make gypsum wallboard. The resulting product may be used in interior or exterior applications and may possess fire resistance, sound ratings and other important properties of gypsum wallboard. As energy costs increase, the novel wallboards of this invention can become less expensive to manufacture than traditional wallboard. The manufacturing process results in much lower greenhouse gas emissions than the processes used to make gypsum wallboard.
