This document discusses solar energy in Europe. It provides information on different types of solar panels and technologies, both active and passive. Applications of solar technology include architecture, agriculture, lighting, thermal uses, and electrical generation. While solar energy has significant potential, challenges remain in developing large solar plants and retrofitting existing buildings. The document then discusses solar energy specifically in countries like Portugal, Romania, Greece, Poland, and Spain, noting the levels of solar radiation, key solar regions, and existing and planned solar energy projects in each country.

1. European Energies
Solar energy group
PORTUGAL, FEBRUARY 2010

3. World Energetic Consumption
79,5% of the energy used by humans came from
fossil fuels in 2000

Agency

4. Concepts
•Solar energy is the
energy derived from the
sun through the form of
solar radiation.
•Solar powered
electrical generation
relies on photovoltaics
and heat energies.

5. TYPES OF SOLAR PANELS
Monocrystalline Solar Polycrystalline Solar
Panels: Panels:
- Made from a large crystal - The most common, less
of silicon expensive
- Most efficient, more - it consists of multiple
expensive amounts of smaller silicon
crystals

6. SOLAR TECHNOLOGIES
ACTIVE SOLAR PASSIVE SOLAR
– use photovoltaic - Include selecting
panels, pumps & materials with thermal
solar thermal properties, designing
collectors spaces and buildings
- purpose: converting - purpose: reducing
sunlight into energy the need for
& increasing the alternative resources
supply – supply - demand
technologies technologies

7. APPLICATIONS OF SOLAR
TECHNOLOGY
Architecture and urban • Passive solar
architecture oriented
planning relative to the sun
Agriculture and • greenhouses
horticulture
• Daylighting systems
Solar lighting • Hybrid solar lighting
• Water heating
Solar thermal • Heating, cooling,
ventilation
• Photovoltaics (PV)
Electrical generation • Concentrating solar
power (CSP)

8. FUTURE TRENDS
• POSITIVE
- Experts estimate the sun’s ability
to produce 10,000 times as much
energy as the Earth produces
- preoccupation and extensive
research in this area
• NEGATIVE
- the challenge of creating solar
plants because of the restricted
sunny area
- the challenge and expenses of
the constructing new buildings and
refitting old ones
EXPECTATIONS
- ´20 20 20´ EC strategy.
- Solar thermal power industry will
grow from 1,2 GW in 2009 to 14
GW in 2014

9. What can WE do?
• In spite of all the progress, the future of
energy lies in our own hands and actions:
 installing solar panels
 donating to research organizations in the
field
 studying science or engineering
 voting for measures directed to alternative
energy development
