Currently in the Czech Republic we observe relatively large development of energy efficiency projects including energy production from RES, in particular electricity. This development is interconnected with the current legislative framework for such support in the Czech Republic and related support mechanism in the form of investment and operating subsidies for electricity production from RES. Current status of implementation of these projects is particularly affected by our membership in the EU and the subsequent implementation of the EU respective directives into national legislation. Furthermore, the Czech Republic has achieved a significant success in international emissions trading (IET International Emission Trading) by selling its surplus CO2 emissions under the Kyoto Protocol. In comparison with other EU countries the Czech Republic belongs to the frontrunners in terms of implementation of energy efficiency projects, mainly in the context of recent strong development of photovoltaic power installations. The article presents a basic overview of Operational Programmes financed by SCF EU, under which energy saving and RES projects in the private and public sector are supported, the Green Savings programme, designed for household sector and financed by selling CO2 emission surplus, and the system of feed in tariffs for RES electricity production. Based on currently available ex-ante evaluation of the supported projects the article quantifies the anticipated benefits of these projects in terms of savings in the final energy consumption and in terms of increase in energy production from RES.

Elementary principles of the most significant and the most perspective types of fuel cells are presented (AFC, PEFC/PEMFC, PAFC, DMFC, MCFC, SOFC). For every of the fuel cells the main operational characteristics, chemical reactions, advantages and disadvantages are presented.

The article is a translation of author´s presentation reported in January 2009. Presentation is focused on two strands: 1) Oil Peak and 2) related experience of the structural transformation during the ascent to Oil Peak. The last part is attempting to answer the question "What might the descent from Oil Peak be like?"

In the first part of the article is a brief overview of the market of collectors of solar radiation in the Czech Republic, the basic layout of different types of collectors and major part of solar systems. Following parts provide some basic connection of solar systems for various heating load (hot water, heating, swimming pool) and a simplified design absorber area. Each scheme is briefly described its function. In conclusion, it is marked possible connections of storage tanks for different performance.

This contribution summarizes utilizing of co-generation and tri-generation systems for effective electricity, heat and cool production. A co-generation and a tri-generation offer more effective utilizing of primary energy sources in comparison with separate production of different kinds of energy. This contribution describes actual state in the Czech Republic in year 2009.

More than 15 years TZB-info is focused to perspective equipment for building services with priority in heating. During this period the main question: "how to heat" shifted to question: "how to reduce heat loses". For example France is planning for new buildings only passive standard, and begining 2050 only so-called quasi-zero buildings. In Czech Republic one of significant impulses is subsidy program Zelená úsporám (Green for savings). Technical solutions are widely known in professional community, unfortunately high investment cost and long payback time are the main barriers for broader expansion of the solutions. Folowing article is the first from a serie focused to long time planing of reduction of energy consumption in the Czech Republic. From two ways - to prospect new energy sources or to reduce energy consumption - the second needs no to destroy another villages or towns.
How can heating for Czech homes be assured while at the same time get rid of the dependence on dirty coal and Russian gas? This is answered by the scholarly study by the DUHA movement – Clean Heating. The solution is based on a combination of investments on home insulation, solar collectors and biomass heating plants. Very important are the new standards for developers and provisional supply of coal from the Bílina mine. The calculations are based on those from the Pačes Commission. There are many opportunities. Increasing the energy efficiency of builings – i.e. insultaions – and the heating potential from renewable sources represent more than 300 million gigajoule. This surpasses the total current heating consumption of Czech homes. The possibilities of insulating Czech homes are also five and a half times higher than the controversial expansion of the coal mines around Most, which is linked with a further devastation of the North Bohemian landscape and the demolition of towns.

Nowadays, the support for the production is renewable energy is growing. Biomass is among the important sources of renewable energy. It can be used in biogas plants as a raw, organic material of various origins, or as a “dry” biomass with low moisture, which is suitable for the production of energy through incineration. Both electricity and heating can be produced with biomass. And that is actually the problem. Whereas the production of electricity is supported, support for the production of heat is still missing.

The current boom of photovoltaic energy installation is such that even the laboratories of the Science Academy of the Czech Republic have been asked which is the best photovoltaic panel. There is no easy answer for such question. The ideal panel should have the highest efficiency, which should be independent of either temperature or intensity of illumination. In addition, the panel should not degrade, nor should need maintenance and should be the lightest, yet strong and durable. Thus far, nobody has built such panel (and price is not even being considered). Will we see in the future more efficient panels? Not easy with the conventional silicon technology. One thing is to build complex technology by way of a record cell of 1cm2, and another, to mass produce square kilometres of low-cost photovoltaic cells. However, the advent of nanotechnology is bringing new ideas that will lead to increased efficiency of photovoltaic cells. Further research and development, together with mass production, are bound to progressively make photovoltaic panels less expensive. In 10-15 years photovoltaics will be able to directly compete with other forms of electricity production, and the installed capacity will be in the hundreds of gigawatts worldwide.

The gross production of electricity from renewable sources in 2008 was 5.2% of the national gross electricity consumption. The share of renewable energy in primary sources reached 5%. The share of renewable energy sources in the production of thermal energy is around 7%. According to the Ministry of Industry and Commerce, in 2009 the share of electricity coming from renewable sources was 6.8% of the final electricity consumption in the Czech Republic.

The calculate the balance of annual fuel requirement it is important to correctly determine the specific calorific value of the fuel and to asses the real efficiency of the boiler itself. Not always this data is consistent with what is reported by manufacturers or retailers of pellets and pellet boilers. Just to get an idea, for a 1kW heat loss the consumption would be 520kg of high quality pellets. This is of course an estimate, because it depends on the concrete weather conditions in a given year (length of the heating season, etc.), but it also depends on the chosen temperature for the heated area (for some people 22ºC is too much, others feel cold even at 26ºC. It is normally calculated that to heat water for a family of four the annual consumption is 25GJ. That, calculated for a boiler and pellets gives as an approximate of 1.7 tonnes of pellets a year.

In the last few years, the concept of sustainability has become a universal trend in the Western countries. All political programs include sustainable housing, economy or management. Although the expression “sustainable development” is in itself a fundamental paradox, it (and everything related to it) has become a victim of the market, or more specifically, of consumerism.

The paper presents the possibility of heating regulation by using of zoning regulation systems. The paper describes the main functionality of zoning wired a wireless regulating systems. Detail description of wired and wireless zone systém differences is mentioned. By using of zone regulating systems it is possible to reduce heating costs and improve comfort in our homes.
