The use of GE depends on the predisposition source, namely geothermal boreholes. The use itself is different when using the heat for heating, hot water, heating greenhouses and plastic greenhouses (agricultural), recreation facilities, but also for various technologies. The inclusion of monitoring and control system for an open geothermal energy system is achieved by taking friendly geothermal water and substantially increases the life of the whole work.

Secretary of State for Energy and Climate Change, Chris Huhne, proclaimed: "Renewable energy technologies will deliver a third industrial revolution." He criticised "faultfinders and curmudgeons who hold forth on the impossibility of renewables – the unholy alliance of climate sceptics and armchair engineers who are selling Britain’s ingenuity short."

Regular inspection is focused to the boiler, smoke flue and accessories condition, its security and regulation. In addition to the technical condition and maintenance, the documentation, operating instructions, manuals and other documents are under inspection. It quantifies the overall boiler efficiency of measurement results, sets reference respectively minimum boiler efficiency and suggests possible actions.

Oil is the energy source No. 1, and the world is in a period of peak oil. Serious paralysis of economy after peak oil is almost certain, because economic growth demanded increasing consumption of fossil fuels from the beginning of the industrial revolution.
The Czech Republic can ensure its energy security only in integrating with Europe, and especially the connection to Europe's energy (especially electricity and gas) and transport networks and participation in the transformation of post-fossil energy and transport system.

In 2010 it was delivered to the domestic market, over 80 thousand small combustion plants for solid fuels. Of these, 24 000 stove and fireplace inserts, stoves 50 000, less than 5000 kitchen ranges and over 1000 spa stoves. Around 50% of these devices are imported. Hot-water heat exchanger is fitted with 15-20% of sold heaters.
