The contribution describes the building and configuration of a newly built ground heat exchanger (GHE), realized under the grant No. 3206/2011/G1 provided by Universities Development Fund of Ministry of Education, Youth and Sports CR. This GHE is designed as an accessory of experimental low-energy dwelling of FME BUT Brno exploited for education in the area of alternative HVAC systems. All relevant operating parameters (including temperature stratification of soil) are continuously monitored. Data acquired this way will be used for validation of recently developed numerical models as well as for later design and energy assessment of GHEs.

Sewage water contains organic compounds, thermal and kinetic energy, the amount is about 9 times higher than is needed for cleaning. The biggest source of heat energy are beyond the wastewater treatment plants, hotels, schools, restaurants, hostels, administrative buildings and other public facilities. Also, a wellness center, swimming pools, spas, and hospitals.

Comparison of price developments in eight EU countries shows very interesting facts. Eg. for common Czech household with consumption 2.5-5 MWh / year electricity price increased in 2011 to 229% of the price in 2001. While the same household in Germany to only 115%. While the current price is very close (CR 3.07, Germany 3.50 CZK / kWh).

Article comments on the climate conference in Durban and generally evaluates negative results so far made climate conferences. Sad is that, the last climate conference in Doha ended with the same result - with no progress in reducing greenhouse gas emissions.

Directive 2010/31/EU of the European Parliament and of the Council on the energy performance of buildings requires that new buildings since 2018 (public buildings) and 2020 (all buildings) respectively were buildings with nearly net zero energy buildings. The requirement relates to the all technical systems of the buildings. The paper presents possible solutions in ventilation and air conditioning field in these buildings and presents considerations about possible developments with regard to the requirement of reducing energy consumption.

The article presents an extensive and detailed analytical study that explores in detail the possibility of directing the development of the European energy industry in order to achieve a significant reduction in greenhouse gas emissions and a significant decarbonisation of the energy sector. Roadmap is not to be predictions or plan for further development, its goals are more modest, to lend a hand in finding their own paths to member countries to a sustainable, economically viable and environmentally acceptable energy economy.

It is generally recommended that the wood for quality burning should not have more than 20% by weight of so-called energy moisture. The described method allows a unique determination of moisture content of firewood at home.

So far, both the feed-in-tariff (FiT) and the green bonus (GB) was paid by locally relevant electricity distributor. From January 1^st 2013 the new entity enters into the transaction - OTE (Energy Market Operator). The renewable electricity will be purchased by electricity traders instead of distributors. Newly will be introduced a new scheme - hourly green bonus. The rights of existing manufacturers are fully retained.

Miners’ protest in front of the Office of Government at 31st October 2012 against deleting the "expropriation paragraphs" in the Mining Act and reaffirm the validity of the so-called "territorial ecological limits" in the North Bohemian lignite basin by the Czech Government turned attention of the public to context of surface mining of lignite.

Proposed support for heat production from RES is set for all resources defined by law to a maximum of 50 CZK / GJ (equivalent to approx 0.16 CZK / kWh) with a regular annual increase of 2% because of the anticipated inflation. Compared to the current level of support for the production of electricity from renewable sources this is about 10 times lower.

Evaluated the effectiveness of austerity measures must take into account both external and internal temperature of the object and the value of the average heat gain at which heat consumption was measured. Article analyzes the individual components, and presents the average values.

The article is research on the thermal properties of various construction types of thermal drillings. It focuses on the impact of their installation on their efficacy, duration and cost and to their safety for underground water and water-related ecosystems.

Our Western society is in crisis. It is increasingly obvious, that the crisis is not only economic, but it is more serious - a societal crisis. The post-war (still) high prosperity of the Western civilization is due to fossil fuels and bipolar world. Unfortunately the bipolar world ended with disintegration of the Soviet Union, and the world of fossil fuels is only an episode on the timeline of humanity. Even from the perspective of only two next generations, nowadays we are not able to predict what will be the life of our children and grandchildren like. Undoubtedly, for preservation of the core values of the Western civilisation (democracy, standard of living) transformation of both the energy and transport systems, and the way of life will be crucial. For this transformation we have much less time than the development of the Western society took from the beginning of the industrial revolution, because of the energy return of the remaining fossil fuel resources is permanently decreasing.

The article presents the current state of the issue of flat hybrid photovoltaic-thermal (FVT) collectors, focused on the differences between the basic types of collectors, their advantages and disadvantages. There is also presented an overview of the current global manufacturers. The article aims to highlight the problems but also the opportunities associated with different types of the hybrid FVT collectors.
