California economy. A baseline scenario in which California relies on imported electricity to meet future demand is then compared …

As part of its climate strategy, the EU aims at increasing the share of electricity from renewable energy sources (RES …-E) in overall electricity generation. Attaining this target poses a considerable challenge as the electricity sector is … “locked” into a carbon-intensive system, which hampers the adoption of RES-E technologies. Electricity generation …

The reduction of electricity use for heating and domestic hot water in cold climates can be achieved by: (1) reducing … the heating loads through the improvement of the thermal performance of house envelopes, and (2) using solar energy … a reference house for the study of long-term thermal storage. Third, the computer simulation of a solar heating system …

Earth-air heat exchange (EAHE) systems offer the possibility of reducing use of nonrenewable energy for heating … cold climates is small. Even less has been reported on their heating performance, but the available information suggests … heating with EAHE were found for cool climates. Four articles that addressed ground temperature effects with horizontal ground …

, especially for space heating and cooling, are closely linked to several weather variables, mainly air temperature. The analysis … temperature. Base temperature should be chosen to coincide with the minimum energy consumption. In this way, changes in heating …

. Calculations included pig number, slurry (manure water mixture) dilution, retention time and biogas/solar heating. Although using …:9 slurry dilution rate commonly used on pig farms. However, at a 1:3 slurry dilution, the use of solar heating to provide 90 …

The old electricity network infrastructure has proven to be inadequate, with respect to modern challenges such as … alternative energy sources, electricity demand and energy saving policies. Moreover, Information and Communication Technologies … electricity network — the smart grid. In this work, we will analyse the state-of-the-art of smart grids, in their technical …
