One of the biggest obstacles to economic profitability of solar water heating systems is the investment cost. Retrofitting existing domestic hot water heaters when a new solar hot water system is installed can reduce both the installation and material costs. In this study, retrofitting existing...

Increased demand response is essential to fully exploit the Swedish power system, which in turn is an absolute prerequisite for meeting political goals related to energy efficiency and climate change. Demand response programs are, nonetheless, still exceptional in the residential sector of the...

Encouraging consumers to use less electricity through information is essential for sustainable use of energy and demand response is indeed a key component of the smart grids concept. The aim with this study is to understand differences between consumer categories and what this could mean e.g. to...

Household energy accounts for one of the major contributors to the countries energy balances. It has been shown, that an effective way to achieve energy saving in that sector, is by providing consumers with information and feedback. This measure increases home inhabitants’ awareness that leads...

Improved means of controlling electricity consumption plays an important part in boosting energy efficiency in the Swedish power market. Developing policy instruments to that end requires more in-depth statistics on electricity use in the residential sector, among other things. The aim of the...

Despite all initiatives introduced for maximizing energy savings domestic energy consumption is in constant increase. However, very little investigation has been carried out on the integration of household’ consumption trends, the parameters influencing them and the characteristics of the...

The electric grid is changing. With the smart grid the demand response (DR) programs will hopefully make the grid more resilient and cost efficient. However, a scheme where consumers can directly participate in demand management requires new efforts for forecasting the electric loads of...

There is a potential to utilize a significant amount of renewable energy in Sweden and European union (EU). Biomass can fulfil some 8500–12,500 TW h/y in EU, while the total utilization was 16,084 TW h/y 2009. Even though there is a significant amount of wind power, hydro power and...
