Since
the
90s
of
the twentieth century,
the EU has encouraged
the
use
and production of
renewable
energy.
Such a
promotion
leads
to
the restriction of fossil
fuel
consumption.
It
also
results
in
the diversification
of
used
energy sources and contributes to the
protection
of energy supply,
and the development of
new industries
and
technologies. In
recent
years,
a
rapid
development of
techniques
for
collecting
energy
from
renewable
resources (wind,
solar, biomass, geothermal)
has been observed. However, the prices relating to traditional fossil
fuels are getting higher. This stems from the fact that more and more
people start paying attention to the environmental problems at the
same time increasing their environmental awareness as well. On the
other hand, the main reason for this may also be hidden in the policy
and economy crisis, which is responsible for the immediate price
rise. Luckily, the cost of devices used for renewable energy
production are becoming cheaper. Thanks to this, is it more likely to
find a group of potential buyers. Besides, there have been a lot of
legislative
changes
to
promote
the use
of renewable energy
in
many
cases
allowing one to apply
for
preferential
loans
or
grants
to
make
the
investment.
The aim of this project is to focus on the subject of the renewable energy, its definition and various types. The worksheet will also present the attitude of both EU and Poland towards the Renewable Energy Sources (RES).
According to the definition the renewable energy is energy which comes from natural resources like sunlight, wind, rain, tides, and geothermal heat. They are all renewable, which means that can naturally replenish. It is assumed that about 16% of global final energy consumption comes from renewables, with 10% out of traditional biomass, which is primarily used for heating, and 3.4% from hydroelectricity. New renewables such as small hydro, modern biomass, wind, solar, geothermal, and biofuels have been estimated to be about 3% and they are increasing very fast. The share of renewables in electricity generation is around 19%, with 16% of global electricity coming from hydroelectricity and 3% from new renewable.1
For
instance, Brazil has one of the biggest renewable energy programs in
the world, involving production of ethanol fuel from sugarcane, and
ethanol now provides 18% of
the country's automotive fuel.
Ethanol fuel is also widely available in the USA. Moreover, wind
power is increasing at the rate of 30% per each year, with a
worldwide capacity of 198 gigawatts (GW) in 2010. It is extensively
used in Europe, Asia, and the United States. Furthermore, solar
thermal power stations operate in the USA and Spain, and the largest
of these is the 354 megawatt (MW) SEGS power plant in the Mojave
Desert.
In
addition,
the world's largest geothermal power installation is
the Geysers in California, with a rated capacity of 750 MW.
“While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development. As of 2011, small solar PV systems provide electricity to a few million households, and micro-hydro configured into mini-grids serves many more. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves. United Nations' Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity.”2
All
concerns about the climate change, in connection with high oil
prices, peak oil,
and growing government support, help in a way
to increase renewable energy legislation, incentives and what is more
commercialization. No wonder that new government spending, regulation
and policies facilitated the industry weather the global financial
crisis better than many other sectors. According to a 2011 projection
by the International Energy Agency, solar power generators will
possibly generate the majority of the world’s electricity within 50
years, radically restricting the emissions of greenhouse gases that
damage the environment.
Wind
power
is the conversion of wind energy into a useful form of energy, such
as using wind turbines to make electricity, windmills for mechanical
power, windpumps
for water pumping or drainage, or sails to
propel ships. Nowadays, the long-term technical potential of wind
energy is supposed to be 40 times current electricity demand or five
times total current global energy production. This might require wind
turbines to be set up over huge areas, predominantly in regions of
higher wind resources.
Wind power usage
There
are now many thousands of wind turbines with a total nameplate
capacity
of 194,400 MW. The United States pioneered wind
farms and led the world in installed capacity in the 1980s and into
the 1990s. In 1997 German went beyond the U.S., but in 2008 the U.S.
got back its position. In addition, China rapidly expanded its wind
installations in the late 2000s and in 2010 to become the world
leader.
Europe
had 48% of the world total wind energy in 2009. In 2010, Spain
achieved 42,976 GWh becoming the Europe's leading producer of wind
energy. Nonetheless, Germany took the first place in Europe as far as
installed capacity goes, with a total of 27,215 MW
at December
31, 2010. Wind power is approximately 21% of electricity use in
Denmark,18% in Portugal, 16% in Spain, 14% in the Republic of
Ireland, and 9% in Germany
Hydropower is power that is taken from the energy of falling water, which may be used for practical goals.
It
is widely known that hydropower has found its use in irrigation and
the operation
of different mechanical devices, such as
watermills, sawmills, textile mills, dock cranes,
and domestic
lifts, since the ancient times. Furthermore, the term defines the
combination with the modern development of hydro-electric power, the
energy of which can be easily passed on great distance between where
it was produced to where it was consumed.
Hydropower usage
Energy
in water can be harnessed and used. As water is about 800 times
denser than air, even a slow flow of water, or moderate sea swell can
yield significant energy amounts.
There are quite a few forms
of water power presently in broad usage, and other forms which are
still in phases of development. The majority of hydropower is used
mainly to produce electricity, but some are simply mechanical.
Broad
categories include: riverine energy and hydropower. The first on
relates
to Conventional hydroelectric, referring to
hydroelectric dams, run-of-the-river hydroelectricity, which captures
the kinetic energy in rivers or streams, without the use
of
dams and finally, pumped-storage hydroelectricity which pump up
water, and take advantage of its head to create in times of demand.
On
the other hand, marine energy includes: marine current power, which
captures
the kinetic energy from marine currents, osmotic
power, which channels river water into
a container separated
from sea water by a semi-permeable membrane, ocean thermal energy,
which exploits the temperature difference between deep and shallow
waters. There are also: tidal power, responsible for getting energy
from the tides in horizontal direction and wave power, which uses
ocean surface waves to generate power.
Solar energy is the energy which is a result from the sun activity, known as solar radiation. In this particular mainstream solar powered electrical generation relies on heat engines and photovoltaics. Some solar appliances includes cooling and space heating through solar architecture, solar cooking solar hot water, daylighting and high temperature process heat for industrial aims.
Solar energy usage
Solar
technologies are generally described as either passive solar or
active solar.
This depends on the way they capture, change and
allocate solar energy. Active solar techniques comprise the use of
photovoltaic panels and solar thermal collectors to exploit
the
energy. On the contrary, passive solar techniques concentrate on
adjusting a building
to the sun, choosing materials with
favorable thermal mass or light dispersing properties, and designing
spaces that naturally circulate air.
The
definition of biomass states it as a plant material with the energy
it contains coming from the sun. The energy plants capture takes
place through the process
of photosynthesis, and when they are
burnt, the sun's energy they have is released. In this way, biomass
acts as a natural battery for accumulating solar energy. As long as
biomass
is created endlessly,
with only as much used as is grown, the battery will last for an
indefinite period.
On
the whole, there are two core approaches to using plants for energy
production: growing plants specifically for energy use, and using the
residues from plants that are used
for other things. However,
they can be altered in various regions depending on climate, soils
and geography.
Biomass usage
Biomass
can be used directly, or converted into other energy products such as
biofuel.
As for the first one, biomass is plant matter used to
produce electricity with steam turbines & gasifiers or generate
heat, frequently by direct combustion, for instance: forest residues
(such as dead trees, branches and tree stumps), yard clippings, wood
chips and even municipal solid waste. In the second case, biomass
includes plant or animal matter that are changed into fibers or other
industrial chemicals, as well as biofuels. Industrial biomass can be
obtained from many kinds of plants, such as miscanthus, switchgrass,
hemp, corn, poplar, willow, sorghum, sugarcane, and a diversity of
tree species, starting from eucalyptus to oil palm.
Biofuel
is a kind of fuel whose energy is a consequence of biological carbon
fixation. Biofuels are called fuels derived from biomass conversion,
as well as solid biomass, liquid fuels and a range of biogases.
Despite the fact that fossil fuels originate from ancient carbon
fixation, they are not regarded as biofuels since they contain carbon
that has been "out" of
the carbon cycle for a very
long period of time. Biofuels are becoming more popular due
to:
oil price spikes, fear of greenhouse gas emissions from fossil fuels,
and support from government subsidies and the need for increased
energy security.
Biofuel usage
In
2010 worldwide biofuel production was estimated to be about 105
billion liters (28 billion gallons US), up 17% from 2009, and
biofuels provided 2.7% of the world's fuels
for road transport,
thanks to an immensely large amount of ethanol and biodiesel. What
is more, ethanol fuel production reached 86 billion liters (23
billion gallons US) worldwide
in 2010. The leaders were the
United States and Brazil gaining 90% of global production.
On
the other hand, the world's largest biodiesel producer is the
European Union, accounting for 53% of all biodiesel production in
2010.
“As
of 2011, mandates for blending biofuels exist in 31 countries at the
national level
and in 29 states/provinces. According to the
International Energy Agency, biofuels have
the potential to
meet more than a quarter of world demand for transportation fuels by
2050.”3
Geothermal
energy is energy which is obtained by two ways. Both are a result
of
trapping the heat of the earth itself, but the first is from
kilometers deep into the Earth's crust in volcanically active regions
of the planet, and the second from shallow depths,
as in
geothermal heat pumps in most locations of the globe.
The
geothermal energy is derived thanks to three types of power plants,
namely:
dry steam, flash, and binary. As for the dry steam
plants, they take steam out of fractures
in the ground and use
it straightly to drive a turbine that spins a generator. In relation
to flash plants, they take hot water, usually at temperatures over
200 °C, out of the ground, and allows it to boil as it rises to
the surface then separates the steam phase in steam/water separators
and then runs the steam through a turbine. Finally, in binary
plants, the hot water flows through heat exchangers, boiling an
organic fluid that spins the turbine. The condensed steam and
remaining geothermal fluid from all three kinds of plants are
injected back into the hot rock to pick up more heat.
Geothermal energy usage
The
most known geothermal power sources exist in some parts of the world
such as Chile, Iceland, New Zealand, United States, the Philippines
and Italy, which are geologically unstable. The two major regions for
this in the United States are in northern California
or in the
Yellowstone basin and. As fas as Europe goes, Iceland produced 170 MW
geothermal power and heated 86% of all houses in the year 2000
through geothermal energy.
Advantages:
does not cause pollution,
does not contribute to greenhouse gas emissions,
does not involve the exploitation of depleted resources.
Disavantages:
Wind turbines:
Disfigure landscape,
Emit a noise,
A threat to birds.
Advantages:
Production of electricity from water:
does not contribute to greenhouse gas emissions,
does not cause pollution,
does not involve the generation of waste.
The advantage of hydropower is also possible to use the water for example, flood protection, fisheries and recreational purposes.
Disadvantages of hydropower:
Although hydropower is a renewable source of energy, hydroelectric power plants - especially the large ones - can have a negative impact on the environment:
construction of a large dam is associated with considerable flooding areas
under water may be found in agricultural areas, historical sites,
animals and birds can lose their natural habitat.
Advantages:
does not contribute to greenhouse gas emissions,
does not cause any pollution,
does not involve the production of waste.
Disadvantages:
daily and seasonal variability of solar radiation,
low density of the daily flux of solar radiation energy, which even in equatorial regions is only 300 W/m2, while in Poland does not exceed 100 W/m2 (ie 1000 kWh/m2 per year),
difficulties with storage - currently in use allow the hot water storage tanks store energy produced from solar thermal energy only for 1-2 days,
high prices of equipment.
Advantages:
zero balance of carbon dioxide emissions - the amount of carbon dioxide emitted during combustion is balanced by the amount of carbon absorbed by plants through photosynthesis,
less than that of fossil fuel emissions of other pollutants,
use of local energy sources,
creating new jobs, especially in rural areas,
development of wasteland and waste treatment.
Disadvantages:
relatively low density material, making it difficult its transport, storage and dispensing,
wide range of biomass moisture, impeding her preparation to use for energy purposes,
less than that of fossil fuel energy value of raw material: to produce the amount of energy that is obtained from a ton of good quality coal need about 2 tons of wood or straw,
Some wastes are only available seasonally.
Advantages:
clean pollution-free energy,
reduction of methane emissions to the atmosphere (methane increases the greenhouse effect),
decentralization of energy production,
biogas can be used in developing countries with no natural resources.
Disadvantages:
the need to comply with the strict requirements of the fermentation process,
capital expenditures.
The attractiveness of geothermal sources of evidence:
availability, sources are not subject to fluctuations of weather and climate,
sources are not undergoing depletion,
indifference to the environment - geothermal energy does not release any harmful substances,
geothermal technology devices do not occupy much space and do not affect the appearance of almost no landscaping.
Disadvantages:
side effect of the use of geothermal energy is the danger of pollution of the atmosphere, as well as surface water and deep sea by harmful gases and minerals - one of them is hydrogen sulfide (H2S), which in high concentrations can be hazardous to human health,
there is a risk of displacement of the geothermal resources, which for decades can "escape" from the place of operation,
Convenient to use geothermal conditions occur in a few places.
Since
about twenty years in discussions about environmental care, equitable
distribution of wealth and better living conditions is used, the term
"sustainable development". It includes not only ecological
aspects but also economic and social changes that should always be
considered together, taking into account the interdependence existing
between them.
One of the key factors of sustainable development
is energy. The method of obtaining
it affects virtually all
aspects of social, economic and political rights, on the environment
and the associated climatic conditions, and often also on
whether the different nations live together in peace or in conflict.
Forecasts of the use of fuel and energy for the world
and for
individual countries predict that coming decades will increase the
proportion
of energy from renewable sources in the total amount
of energy supplied. More and more
it becomes apparent that the
rapid development of renewable energy is essential for
a
sustainable energy economy.

The so-called. New Targets of the EU (3x20% +10%)
At
the European Council Summit 8-9 March 2007. adopted an Action Plan
to integrate climate and energy policy of the Community, to
limit the increase in global average temperature by more than 2 ° C
above pre-industrial levels, and reduce the threat
of rising
prices and limited availability of oil and gas.
Assumptions of the new Plan:
Reducing greenhouse gas emissions by 2020. at least 20% compared to 1990.
Rationalization of energy use and consequently reduce consumption by 20%.
Increasing the share of electricity production from RES to 20% of total energy consumption in the EU average in 2020.
Achieve at least 10% share of biofuels in transport fuel sales in 2020. in all Member States.4
In
the Act - Energy Law defines renewable energy as a source in the
processing of using wind, solar, geothermal, wave, tidal, river and
fall biomass, biogas, landfill and biogas produced in the process of
discharge or wastewater treatment or decomposition of plant
and
animal remains.
An
important factor influencing the development of renewable energy are
also regulations for acquisition of investments in renewable energy
grants and concessional loans, granted by the National Fund for
Environmental Protection and Water Management.
An important
element of support are also resources from EU funds spent on
renewable energy development under the Operational Programme
"Infrastructure and Environment"
Strategy for renewable energy development:
The "Energy Policy of Poland until 2025" was adopted by the Council of Ministers on 4th January 2005.
This policy includes focuses on the promotion of the development of renewable energy, among other areas.
It
suggests that the share of electricity from renewable sources in the
country's total gross consumption of electricity should attain 7.5%
in 2010. This is in line with the indicative quantitative objective
stipulated for Poland in Directive 2001/77/EC of 27th September 2001
on the promotion of electricity produced from renewable energy
sources. Poland's energy policy directs that this target should be
carried out in such a way as to ensure that
the utilisation of
individual kinds of renewable energy sources favours competition
through promoting the most economically-effective sources and does
not to lead to an excessive increase in energy costs for consumers.
Legal and financial instruments:
Separation of the physical characteristics of the ecological characteristics of renewable energy.
The obligation to purchase energy from renewable sources.
The
obligation to obtain and submit to the redemption of certificates of
origin of RES
for electricity retailers.
The replacement fee.
The penalty for failure of duty.
Relief of 50% in the costs for joining the RES.
Separate rules for balancing energy from wind turbines.
Exemptions
from fees for obtaining licenses and for obtaining and recording
of
certificates of origin for the sources of <5 MW.
Tax credits.
Institutions providing investment aid for renewables.
The National Fund for Environmental Protection and Water Management.
The Province Funds for Environmental Protection and Water Management.
Bank of Environmental Protection.
Foundation Ekofundusz.
Commercial Banks
Coordination of activities:
The tasks associated with RES are implemented by:
Ministry of Environment (coordination of RES, climate change, Nature 2000, EIA, hydropower, geothermal, biomass, forest).
Ministry
of Economy (the efficiency of energy used, the RES in the
electricity
and district heating, biofuels).
Ministry of Agriculture and Rural Development (production of biomass and bio fuels).
Minister of Construction (thermo, architecture, passive).
The Ministry of Maritime Economy (wind farms at sea).
Wind
energy is stochastic and uncontrollable and those features make
difficult
the development of wind power plants. The most
favourable conditions for wind energy in Poland are in the northern
and eastern parts of the country
In
Poland, the average wind speed is 2.8 m / s in summer and 3.8 m / s
in winter, only in few places exceeds the seasonally 5m/sek wind
speed, which is the absolute minimum
to power wind turbines.
The consequence of low wind is that wind turbine built in Denmark
will provide 100 kW, while the same power plant built in the region
of Szczecin will provide only 17.3 kW. Only the Baltic Sea near
Darłowo, Puck and Kolobrzeg, in the vicinity
of Suwalki and
Podkarpacie can talk about favorable conditions in terms of location
of wind farms. There are also windmills have become part of the
landscape. Experts from
the Technical University of Szczecin
even claim that the role of wind energy in the energy balance is
Polish and will continue to slow. The problem of silence, the wind
also affects many of German wind farms localized along the Polish
border. 16,000 wind turbines installed in Germany, which could
produce up to 15% of electricity demand, but problems
with the
phenomenon of silence the wind causes, production only 3%.
Polish
hydropower resources are estimated at 13.7 TWh per year, of which
45.3%
is the biggest Poland's Vistula River. 43.6% of the
Vistula and the Oder, 9.8% for the same Oder. The remaining 1.8% of
the rivers of Pomerania. This is a very large and currently unused
potential. Before Second World War hydroelectric power stations on
the rivers
of Pomerania feeding electricity to a sea port in
Gdynia, Gdansk Kartuzom and residents
and the surrounding area.
Currently, Poland is using its hydroelectric resources in only 12%, which represents 7.3% of installed capacity in the national energy system. Unsurpassed leader and benchmark in this area is Norway, obtained from the energy drop of water
Despite of big hydropower stations there exist in Poland about 400 small and very small hydropower stations, which produce 510 – 616 GW•h electricity.
Building
new big hydropower plants are not expected in the nearest future,
as
the potential of waters that is suitable for big power plants have
already been used up. Still there is a chance for small hyropower
stations development.
Poland’s
potential and reserves of geothermal energy are relatively high.
The
perspective reserves of geothermal waters occur in many regions of
Poland(almost 80%). Majority of the water is characterised by low
enthalpy and high mineralization.
Those circumstances make
utilisation of the waters as energy source difficult. Nevertheless
there are many local conditions that cause the development of
geothermal energy probable and effective. These are:
significant reserves of geothermal heat; in spite of their low temperature they are suitable for heat pumps,
facility for cogeneration of geothermal energy with energy of natural gas,
ecological constrains; use of geothermal energy decreases atmosphere pollution,
possibility
to adopt for geothermal installation the old, abandoned test well
and exploratory bore-holes,
possibility to adopt for geothermal installation boreholes being earlier the exploitation boreholes for exploitation oil and natural gas.
The barriers that restrict further development of geothermal energy use are:
lack of coherent policy of government concerning use of geothermal waters,
unfavourable and insufficient law, i.e. high fees and taxes put on geothermal installations (fee for geological information, fee for exploitation of geothermal water).
So far on Polish territory are four geothermal heating plants:
Banska Nizna (4.5 MJ / s, 70 MJ / s),
Pyrzyce (15 MJ / s, the target 50 MJ / s),
Mszczonów (7.3 MJ / s),
Uniejów (2.6 MJ / s).

1. The EU Climate Package of January 2008 is good for Poland; it is ambitious yet fully, achievable; however, it requires departure from current energy policy preserving technical, structures and building on them conservative organisational structures, which stifle innovation.
2.
The Polish national potential of renewable energy sources permits the
contribution
of renewable energy to the final energy
consumption balance in Poland at the level exceeding 21 % in 2020 and
nearly 60 % in 2050.
3. The 15% contribution of renewable energy to energy consumption in Poland in 2020 means the need for new projects at the level of (maximum) 10 GW of electricity, 30 GW of heat and 50 PJ/year production capacity in biofuels.
Problems: access to capital and limited supply of modern technology.
4.
The key issue for the contribution of renewable energy in 2020 is the
use of the potential
of wind power and energy crops, the
sources which are most severely affected
by environment al and
spatial restrictions.
5.
Local (for heat and cold production) use of solar and geothermal
energy and utilisation
of dry and solid biomass waste is the
least controversial. The related technologies will be developed in
conjunction with action aiming at increased energy efficiency at end
users’.
6. Biogas production (first from waste, then from special crops) is an exceptionally advantageous option for cogeneration from the environmental and energy point of view.
7.
Based on the development of renewable technologies by 2020,
achievable in the long-term perspective (2050) is an approximately 55
% contribution of RES to the primary energy balance and 80 % to
electricity consumption as well as the reduction of CO2 emissions
from 10 t/ca to … ?
