A household energy management system uses measurements of the household electricity supply 4 to identify and to determine the energy consumption of individual household appliances. From these measurements, models can be built of the behaviour of the occupants of the house, the thermal properties of the house and the efficiency of the appliances. Using the models, the household appliances—in particular heating and cooling appliances—can be controlled to optimize energy efficiency; and maintenance programmes for the appliances and for the house itself can be recommended to the householder or arranged with a service company.

The present invention provides a way to more effectively estimate energy usage by devices such as servers, including traditional mainframes as well as other enterprise systems. One core idea surrounds the fact that when detailed power consumption information is unavailable for a specific configuration, power consumption is computed/projected/estimated by de-rating the maximum power rating by a power adjustment factor that would more closely project the true power consumption. Under this approach, the power consumption is then provided as a range specifying probable expected lower and upper limits for a given device. This range is more meaningful for planning and decision-making and shows the client a more likely best and worst case energy consumption scenario for their specific device(s), and hence is helpful for planning or server comparison decisions. Cooling, energy costs, energy efficiency, and energy expanded per MIPS are also projected and given as a range instead of a single number. This gives the IT decision maker more accurate information upon which to base IT decision-making.

Hydrogen production is provided via integrated closed-loop processing of landfill gas (LFG) and solid biomass feedstocks such as various agricultural wastes with minimal environmental impact. LFG is purified of harmful contaminants over a bed of activated charcoal (AC) and is catalytically reformed to synthesis gas, which is further processed to pure hydrogen via CO-shift and pressure-swing adsorption stages. Biomass is gasified in the presence of steam with production of a producer gas and AC. The producer gas is mixed with LFG and is processed to hydrogen as described above. High-surface area AC produced in the gasifier is used for the purification of both LFG and producer gas. An integrated processing of LFG and biomass offers a number of advantages such as a high overall energy efficiency, feedstock flexibility, substantial reduction in greenhouse gas emissions and production of value-added product-biocarbon that can be used as a soil enhancer.
