Under free market conditions, there should be a correlation between price and demand. In the electricity market, it is not possible to shift all consumption to hours that are more favourable. Therefore, free market rules do not fully apply to the ele

In Estonia, wood-based heat accumulating stove heating is the traditional method of keeping houses warm during the cold period. Over time, district heating has started to replace local heating systems in urban areas. Different heating systems, based

The prices of photovoltaic panels have decreased rapidly in recent years while the prices for inverters have decreased at a slower rate. This causes a situation where the economically optimal ratio between the solar panel and inverter power for new i

The main problem of using renewable energy sources is their stochastic nature. To solve this problem, storage technologies are needed. In this study we explored a system that consists of renewable energy sources (wind and photovoltaic), non-shiftable

The power output of wind farms is directly dependent on the instantaneous wind speed. At variable weather conditions there will be an instantaneous excess of electrical power that cannot be stored by a conventional battery bank. In recent years, grea

The article is concentrated on the energy storage problems arising from microgeneration in private households. The case study involves a small-scale wind and solar electricity production set in a net zero-energy building. Both the net zero-energy bui
