Power industry is one of the greatest producers of waste. The character of waste products from the power industry is quite different from waste arising from the other industrial sectors as concerns its composition, methods of removal and possibilities of use. There has been revealed within the solution of the project “The Resort Research Program in the Force of the Ministry of Environment” ref. no. SP2f3/118/08, bearing the name “the research of real properties of waste considered as an acceptable source of non-standard raw-materials (particularly the secondary by-products from the energy generation) in sense of actual legal requirements for the protection of health, environment and the evaluation of the acquired information for the determination of safety processes and requirements for their use”, that products used for the landscaping, in certain events do not fulfill requirements stipulated for the utilization of waste on the ground surface. It means that construction products made from remainders after the coal burning, being sold as safe, can contaminate the environment more than waste used for the same purpose.

Capacity factor of wind power plants in the Czech Republic according to different sources varies in a huge range from pessimistic “4–14 %” to the optimistic “up to 36 %”. The problem arises when via press releases of the ČTK (Czech Press Agency) erroneous data are distributed, which then influences the public debate.
In fact, the average annual capacity factor of the whole set of wind power plants in the Czech Republic is around 20 % or slightly above this level in the last five years. In the longer term the capacity factor increases, because newer wind farms have annual capacity factor about 25 %.
Pessimistic value of the capacity factor below 15 %, are in a better case based on outdated information, or on data from inconvenient installation locations or turbines with technical problems. In the worst case this involves a focused misinformation. If they are published by not direct opponents of wind energy, suggests such values​​, if they are considered to be related to the total production of electricity from wind in the Czech Republic, the ignorance of the issue.
Optimistic values ​​around 25 % may be related to newer wind turbines in the Czech Republic. Values ​​well above 25 % could be a data of individual wind turbines, results of a shorter period, or the expected results of future installations of which the rated power of the generator is less than would correspond to the size of the rotor.

Concept Data Support Department of the Ministry of Industry and Trade has prepared this statistical report as a comprehensive national statistics on renewable energy sources. The final part of the report provides statistical data of the categories Energy use of waste and alternative fuels, Hydropower, Wind Power, Photovoltaics, Solar thermal systems, Heat pumps and Geothermal energy.

Concept Data Support Department of the Ministry of Industry and Trade has prepared this statistical report as a comprehensive national statistics on renewable energy sources. The second part of the report focuses on energetic use of biomass.

Concept Data Support Department of the Ministry of Industry and Trade has prepared this statistical report as a comprehensive national statistics on renewable energy sources. First part of the report focuses on the position of RES in the energy balance of the Czech Republic and describes in detail the development of the category of biogas and liquid biofuels.

The conference program was a series of legislative innovations in bio-energy in 2014 and specific topics such as finding the actual owners of photovoltaic power plants, stop the construction of biogas plants, description of the principal markets for pellets, the future specifically grown biomass.

Uncertainty of input parameters affected the behavior of people: internal temperature, internal heat gains, air exchange rate enter into the calculation of standardized assessments by EPB. The analysis of these parameters is accurate through operational rating.

Key messages of the publication Limits to Growth are often misinterpreted, especially in the Czech Republic. For example, the input assumptions of the model World3 are referred to as forecasts. Some of the model scenarios are selected, and then they are referred to as predictions of disaster.

The paper presents the derivation of calculating the real efficiency of gas boilers with single-stage atmospheric burner. The cause of looping are states when the minimum boiler output is several times higher than the required nominal heat output for heating. The looping of boiler reduces its operating efficiency.

New rules for cost of heat energy allocation for central heating in houses applying evaluative indicators for these purposes. The Minister for Regional Development approved a draft amendment to Decree No. 372/2001. This amendment allows to increase the share folder of running radiators up to 70 % of total heat energy cost. The distribution of this component to final consumers suffers from a significant systemic problem, and these measures will further worsen the credibility of allocation results.

For the operation of the gas boilers is necessary to ensure the supply of combustion air, and in the boiler room need to guarantee adequate ventilation. Here will be presented formulas for the design of the flow of combustion and ventilation air for the gas boilers type B and for the coal boilers.

Opinions of the professionals concerned on the issue of fire safety in the operation of chimneys, flues and fuel appliances that address the Government Regulation No. 91/2010, are very different. Since this is a very serious issue, TZB-info wants to provide space for professional discussion, which result should be the unification of opinions.

In accordance with the conclusions of the hearing on 23th July 2012 MV - GD FRS CR we propose to establish clear principles of Government Regulation application to convey its goal of fire safety in the operation of chimneys, flues and heating appliances.

Opinion No 160/2013 of the Czech Association for Technical Equipment of the Government Regulation No. 91/2010 Coll. Conditions of fire safety during the operation of chimneys, flues and gas appliances, issued pursuant to the confusion in the application of the Government Regulation.

The article is a commentary on Czech TV report about the feasibility of reducing CO₂ in the atmosphere. To eliminate carbon dioxide from the atmosphere has been proposed a number of methods, many of which are currently at the stage of mere concept. Namely, this includes the artificial trees mentioned in the report. Even if such methods work, there still remains the question of what to do with the captured CO₂. Storage in geological formations is uncertain and material recovery faces high energy demands. In some cases there is a misunderstanding resulting from the confusion of CO₂ and other emissions. Namely on the facade, which allegedly eliminate CO₂ from the air, but in fact it eliminates nitrogen oxides. The only reliable way to reduce CO₂ emissions permanently is to reduce energy consumption.

Solar radiation can be utilised in two basic ways. You can either gain heat from solar thermal collectors or electricity in photovoltaic panels. So far, heating of water by photovoltaics was too expensive to compete with conventional solar thermal collectors.
Weight , durability , and currently even the price of solar thermal collectors is comparable with commercially available photovoltaic modules.
Annual energy yield per unit area is approximately twice in the solar thermal collectors compared to the highest quality photovoltaic modules with cells made ​​of monocrystalline silicon, due to the higher efficiency.
In the summer the photovoltaic modules are better when the working fluid is heated to temperatures above 100 °C. In the winter the breaking point is about 40 °C. The advantage of photovoltaics is the absence of heat transfer fluid and easier transfer of energy produced to the point of use. Electricity can also be used more versatile than heat.
If the investment cost of a complete solution of heating water by electricity from photovoltaic panels, either directly or using a heat pump, is lower than the investment cost of the solar thermal system, the PV water heating can be considered as effective utilization of electricity from photovoltaic plants. Such a solution could then be included as an alternative to any grant support for solar water heating.
