TWO FACES OF THE ENERGY
The energy is the essential factor of the economical,
social and cultural development of the mankind.
Processes connected with production, transmittion and usage of
different forms of the energy, by the virtue of its character and
scale, are for the environment the most arduous processes
carried on by human.
According to IEA, the enrgy demand will rise 54 % till 2025.

THE ENERGICAL EFFECTIVENESS
Taking actions in the range of the legislation or introducing legal rules which will regulate and
sharpen demands on designing buildings with a low heat demand.
Monitoring and propagation actions aimed to reduce the energy consumption by introducing series
of alterations improving the efficiency of the heat and energy systems, preparing warm usable water,
ventilation, air conditioning,etc. as well as using alternative sources of energy- the broadly defined
renewable energy.
Taking marketing actions in this area and promoting and supporting energy-efficient, passsive
building.
Creation of the future politics- development and plan for
the future.

UE DIRECTIVES
Furtherance of electrical energy (juice) production from the renewable sources (2001/77/WE).
The aim of this directive is to rise the share of the renewable sources of the electrical energy.
Connection of heat and electrical energy production (2004/8/WE)
This directive aimed to the improvement of the energy effectiveness and energetical safety by the promotion and
development of the congregation.
Energy effectiveness in the building (2002/91/WE) --- > 2010/31/UE
The aim of this directive is to support the energy effectiveness in the building.
Promotion of the effectiveness of power services and the effectiveness of the energy
consumption by final receivers (2006/32/WE)
The most important aim of this directive is to bring to the more effective energy consumption of the final
receivers by supporting development of an efficiently operating, economically reasoned and competitive market
of worthwhile methods of rising energy effeciveness.

THE ENERGY CONSUMPTION IN BUILDING IN POLAND
1. Twice more consumption than in UE countries
2. 80 percent of properties built in a fashion not allowing to
save energy
3. The energy consumption in communal-living system
includes approximately 45 percent of the total primary
energy carriers demand.

LEGISLATION INITIATIVES - FUTURE
Implementation directive 2010/31/UE The European
Parliament and Council of the European Union, regarding
characteristic and effectiveness of energy wear for heating
and air conditioning EPBD (the Energy Performance of
Buildings Directive).
The main instrument EPBD, which aims to need to use the
energy dissipated is the issue of the construction of buildings
with almost zero energy consumption.

NEED TO FIND A DEFINITION
The building of almost zero energy consumption?!
Near-zero or very low amount of energy required must come
to a very high degree of renewable energy sources
(produced on site or nearby).
if it is:
5? 10?15? 20?25?

POWER DISSIPATED - THE POSSIBILITY OF!
In the distributed energy sector, electricity is produced in
cogeneration with heat in mikrosiłowniach. The source of heat
for micro CHP, you may waste energy, or renewable sources.
There are a number of distributed technologies for low power
generation of electricity and heat.

RENEWABLE ENERGY IN POLAND
BIOMASS ENERGY
Calorific value of biomass two times lower than coal. Need
to baling and briquetting of biomass prior to use.
Problems include:
scattering sources sourcing,
The variety of characters, producers and consumers
WIND ENERGY
The advantage of wind turbines are: no harmful emissions,
the possibility of providing electricity without the need for
construction of transmission lines. It is required to maintain
high reserves of power plants.

RENEWABLE ENERGY IN POLAND
GEOTHERMAL
The use of geothermal resources depends on the temperature of
geothermal water. At temperatures above 120-150 ° C it pays to use
geothermal energy for electricity production. At lower temperatures,
the sources they used for heating purposes.
SOLAR ENERGY
In the area of our country differs little sunshine. Solar energy in Poland
is characterized by a large proportion of diffuse radiation, the so-called.
diffusion rate of around 50% of the total radiation. During the year the
number of sunny hours is 1600.

RENEWABLE ENERGY IN POLAND
Hydropower
Small hydro can harness the potential of small
rivers, reservoirs and farm irrigation systems.
Their task consists in supplying electricity in an
area not connected to the mains, increasing tension
in the final sections of the network and increasing
the reliability of electricity supply customers.

TASKS FOR EXECUTION
1. Conducting research and analysis.
2. Choosing the best ideas.
3. What about the waste heat?
(Technique and method of use, for example, electric
power batteries, power the heating system)
