Renewable energy has many pros and therefore it is desirable by state goverments and th e EU as well. However achiewing of renewable energy aims proceeds at local level. Wrong application can have unwelcome and long-term impacts which many local representatives know very vell.

In late 2014 Photon Energy commissioned a unique solar PV storage project in Australia. Instead of feeding energy into the grid, the 39 kWp / 215 kWh power plant powers a radio broadcast tower. This article explains in detail the set-up of the hybrid PV system, which was designed to prove that renewables can be used for on-site production even for demanding customers. Which technology was used and why? After one year the authors examine production data to evaluate the system’s performance.

In 2002 after seven years gap new wind energy projects started to appear in the Czech republic. But still further development remained as modest as the beginning.

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.

The paper analyses economic situation of heat pump’s users with the new tariff structure, including examples of an older house, new-build house and low-energy house.

Energy-efficient buildings research is one chapter of General Programme for Research and Innovation Horizont 2020 (2014 - 2020) which helps reaching the aims of european energy policy. First part of the article deals with characteristics of private-public partnership called Energy-efficient buildings (PPP EeB) that was founded for this purpose during previous General programme (2007 - 2013) and sums up projects PPP EeB supported in both programmes so far. Second part of the article deals with Czech participation in this programmes and describes topics of nearest Programme Hotizont calls for the year 2017.

The aim of the article is to provide several concrete solutions and applications of Smart Cities that are already being applied in the world and try to describe their contribution to urban residents. We focus on the first two of the six key areas of Smart City – Smart Government and Smart Transportation.

Ministry of Environment has proceeded to subsidize the simple ineffective PV systems for water heating in last call of support programme New Green for Savings. Paper analyses the final impact of this decision on the primary energy savings and associated emission production.

The paper is targeting verification of the possibilities to utilize solar systems with long-term heat storage in residential buildings. Several ways are evaluated how to connect the long-term heat storage system with hot-water storage tank (system with and without use of heat pump, different ways of charging the storage tank, variants with stand-by storage tanks). Evaluation of the system is performed by TRNSYS simulation software.

The article deals with the development of wind energy installations at the turn of the millennium. At the beginning of the 21st century wind energy has become the most dynamically evolving energy industry in Europe. In the period 2000 - 2015 it recorded highest energy growth in installed capacity among all other sources.

Calculation of electricity production by photovoltaic systems can be performed by more or less simplified approach. Monthly balance method allows to include the influence of the temperature and solar irradiance into the monthly production calculation with use of the PV module parameters available in the technical datasheet. Individual PV module technologies are compared by the balance method.

First article from the Smart city series deals with occations for new urban conceptions, defines the Smart City idea and describes it from different points of view.

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

The article describes use of Miscanthus sinensis for a manufacturing of pulp. Miscanthus sinensis is a perennial plant, its cultivating is easy and it can be used for various purposes.
In the first phase of the pulp preparation from Miscanthus, a laboratory preparation of pulp was done at the University of Pardubice in total amount of 6 individual batches. In the second phase a selected laboratory batch was prepared in a pilot production process and ca. 2000 g of pulp in total was generated for further tests.
Mechanical properties and also other properties typical for pulp were determined on prepared samples. The produced pulp was used in the next step for a preparation of fibre-cement boards. Their basic physico-mechanical parameters were also determined.
After evaluation of all data that we have, production of 500 kg of pulp was done. Then the pulp was used to produce fibre-cement boards in a mass production.

Due to high density of electricity grid and large local coal supply in the 20^th century there was no reason to look for energy alternatives in Czechoslovakia. Therefore the wind power development was narrowed to several enterpreneur projects.
