Coverage of Slovakia's energy needs depends primarily on collecting energy from abroad (mostly from the Russian Federation). Therefore, the state is inclined to making substantial use of renewable energy sources, which are also environmentally less aggressive. Slovakia has a significant potential in geothermal energy. The systematic investigation of geothermal energy sources using geothermal wells started in 1971 in Slovakia. There are 120 registered geotherm al wells in Slovakia, which proved about 1787 l.s -1 of...

Some renewable energy sources, such as biomass, hydro, geothermal and tidal energy, produce reliable electricity, which can be distributed to remote locations. Other sources, like solar and wind depend on the weather, but it is predictable and so their usefulness may be suitably amended with permanent renewable energy sources. The vast majority of renewable energy in add ition to their advantages in terms of their source inexhaustibility also has significant drawbacks which significantly limit their expansion. For...

Nor green business, however, designed precisely to reduce the amount of waste that modern society and its technologies generate, is not entirely trouble-free in relation to waste. This problem also applies to photovo ltaic. The issue of life cycle and the final disposal of modules and materials is more or less long a major role for industry. Total amount of photovoltaic waste in Europe is still relatively small and moves around 3800 tons in 2020, this number will grow to 35 000 tones. Sooner or later it will be ne...
