Nuclear fusion is the energy source of the Sun and all other stars. Time is coming when nuclear fusion will produce electricity. A five-part series Mastery of sun describes the state of the art of developing a fusion power plant. The first article deals with the history of this development. Research on controlled nuclear fusion started after World War II and currently designing the first fusion power plant is ongoing. A global project of the experimental fusion reactor ITER will be followed by the demonstration fusion power plant DEMO. The European Union, the world leader in fusion research, plans to deploy DEMO to 2050.

At the TZB-info appeared article "Smart grid is like yetti, nobody has ever seen him, however we can use the CRC" (collective remote control). There is czech pride on CRC present in the headline as well as scorn towards smart platforms in the energetics. Is the problem really black and white? Can CRC offer the same as smart metering? Are the Czechs ahead of time?

The paper aims to discuss the issue of energy modelling and to introduce energy model TIMES-CZ as a new model from the TIMES model family. Internet application allowing individual analysis of impacts of prices changes and policy regulation on Czech energy system untill 2050.

Article features basic relations for determination of heat loss at warmwatter tube with thermal isolation from differences of flue watter temperature and ambient air temperature at planar and cylindric form. Calculation coming-out from coefficient of heat transmission according to coefficient of thermal conductivity and coefficents of heat transfer.

Extraction and combustion of coal have changed the world and the climate of our planet within last two hundred years, but both are declining. This fact alongside with many others belongs to key messages of a new, representative publication, the Coal Atlas. Coal has started the industrial revolution and at the same time caused environmental and social destruction of large areas. At present, coal significantly contributes to climate change by being responsible for 43 % of global carbon dioxide emissions and more than one third of all greenhouse gas emissions respectively. Progressive countries are therefore leaving coal behind. What is more, consumption of coal has recently stagnated also in China, so far the biggest consumer. While the coal business seems to be inevitably coming to the end, some investors still hope for a profit. Why some buy something that the others consider as “stranded assets”?

In December 2015, the scoping stage of the Strategic Environmental Assessment (SEA) process on the Updated Concept of Radioactive Waste and Spent Nuclear Fuel Management began in the Czech Republic. The policy has processed only one option - a geological disposal facility in the Czech Republic. Second part of this article will look into the situation with radioactive waste management in the world.

This article deals with assessment of health and environmental impacts from potential continuation of brown coal mining in the North Bohemian Coal Basin. Four defined mining variants, which are related to a possible modification of the regional ecological limits in the opencast mines Bílina and Československé armády have been reviewed. The impacts are quantified in monetary terms – external costs – using the damage cost approach that reflects site-specific conditions of the assessment and enables us to structure the external costs estimates by the type of the impact on health, agricultural production and biodiversity. In the case of mining process, health effects due to dust emissions and noise pollution on the surrounding population were evaluated. The external cost assessment of extracted coal usage in the defined mining variants for energy purposes consisted mainly in quantification of the health impacts due to primary and secondary pollutants.

The article refers to the new European subsidies for the replacement of boilers in the Czech republic. The author responds to the statement of the Minister of the Enviroment Richard Brabec who said, that the much debated permision to subsidize boilers, which were not verified by an independent authorized person, was necessary because of the requirements of the European legislation.

The article descrtibes selected Solar District Heating implementation business models. Prezented cases are based on actual projects running across Europe.

We calculate insulation thickness in accordance with the criterion of maximum heat loss and monitor unwanted warming or cooling media and maintain the required temperature.

This article reflects the author's view on the issue of emissions from the combustion of solid fuels in small combustion appliances and theirs decreasing by subsidy for boilers’ change. For maximum efficiency of subsidies, author recommends: 1) replace old boilers with modern gasification and automatic boilers, 2) subsidize only boilers certified by independent accredited laboratory, 3) optimize settings of newly installed boiler according to the measurement of flue gas composition and efficiency, directly at the new operator, 4) periodically check emission parameters in real conditions.

Article is dealing with gasification principles and gasifiers. Gasification is process for gas producing from solid fuels (coal, wastes, biomass). Producer gas can be used in cogeneration unit (piston engine or combustion turbine) for generating of heat and electricity with higher efficiency in comparison with combustion in boiler. All processes in gasifier taking place with regulated supply of gasification media (air, oxygen or steam) and reaction heat.

The article describes the transmission grid of the Czech republic and continental Europe.

The article deals with the beginning and development of the energy transmission system in the Czech republic and Slovakia and it's integration to the continental transmission grid.

Methods of cost allocation in apartment buildings have undergone significant changes in recent years. The article offers a comprehensive overview of cost allocation methods in multi-dwelling units according to applicable regulations. It is intended mainly for owners of residential units, board members of homeowners associations, managers of housing cooperatives or individuals and companies managing residential buildings.
Cost allocation in apartment buildings is currently governed by two laws: Act No. 67/2013 Coll. and the new Civil Code No. 89/2012 Coll. These laws governed cost allocation in calendar year 2014 and apply also for 2015. The heating and hot water supply costs in MDUs from 2016 onwards will be allocated pursuant to the new decree No. 269/2015 Coll. and the amended Act No. 67/2013 Coll.
