Biomass-energy use is not a new idea. Earlier the by-products of the production processes or naturally grown materials were mainly used for energy production. One of the answers to the contemporary problems is the deliberate as well as mass production of the biomass, furthermore the planned and...

An overview is presented on the last decade of geothermal heating by ground source heat pumps (GSHPs) in Europe. Significant growth rates can be observed and today's total number of GSHP systems is above 1 million, with an estimate of about 1.25 million mainly used for residential space heating...

In the current study the savings of CO2 emissions due to the use of ground source heat pump (GSHP) systems was investigated in comparison to conventional heating systems. Based on a subsidy program for GSHP systems in southwest Germany, the regional, average, and total CO2 savings of 1105...

In order to achieve national, European and international energy goals, energy efficiency strategies in the building sector have to be implemented. The passive house standard and low energy standards are already successfully established in single dwelling houses. These high performance standards...

This study uses high-frequency appliance-level electricity consumption data for 124 apartments over 24 months to provide a better understanding of appliance-level electricity consumption behavior. We conduct our analysis in a standardized set of apartments with similar appliances, which allows...

Using biomass to produce energy is not a new idea. In the past, the by-products of energy(?) production processes or naturally grown materials were mainly used for energy production. At the same time, during the production of biomass the conventional sources of energy are used (fuels, the...
