2. R.E.S. Importance2. R.E.S. Importance

• Solar Energy : Huge Electromagnetic Radiation

1.7x 10^17 W with a wide spectrum:• It is like the Heart in a body:

as it creates-causes Wind- Energy, Hydro cycle, Biomass……

but of low density as,

Solar Radiation Intensity = 1000 W/m2 at solar noon

in a clear sky • There is a need for Intelligent systems to convert to

other useful forms of Energy towards Sustainability

• The RES potential for every region is a MUST to be assessed

• A campaign for RES, with studies per se is imperative ( see Intelligent Energy for Europe)

• These are main areas of interest for RTD

3. Legislation

Renewable Energy Road Map:• To assess the share of RES in the energy

mix and the progress made towards the 20% of the total energy consumption from RES by 2020

• Measures to be taken to promote RES in the electricity, bio-fuels and Heating &Cooling

• COM(2006) 848 final , 10.01.2007

• Current Contribution (2005)

Energy Electricity

Biomass 66.1% 15.8%

Hydro-Power 22.2% 66.1%

Wind Power 5.5% 16.3 %

Geothermal 5.5% 1.2%

Solar Power 0.7% 0.3% ( Thermal & PV)

Notice: Heating & Cooling accounts for 50% approx. of the fuel energy consumption.

No Legislation to promote. Studies required for the impact to national economies

• For 2010 the target was:

• A 10% of the gross domestic energy consumption to come from RES. But….

• High costs and no- sensitization on the impact of fossil fuels to Health and environment

• Administrative problems, where decentralization of energy production is involved

• Special discriminatory rules are posed governing grid access.

• Inadequate info to suppliers, customers, installers

1. Directive 2001/77/EC

• To promote electricity consumption from RES.

If all m.s. met the target set, then by 2010 the share of RES in electricity would be 21%

2. Directive 2003/30/EC biofuels(5.75% by 2010)

3. Directive 98/70/EC on Fuel Quality…to be amended to include bio-fuels

4. Competitive and Innovation Framework Programme. C.I.P. 2007-2013

7. Expectations : Needs, Problems, Solutions

The rational management of renewable sources is getting more and more necessary and demanding.

Emphasis has to be given for a harmonic chain process of :

Production Consumption Offer Power Demand Source Load

•Target :

The most cost-effective type of energy in relation to the

Consumer / loads

(types and load characteristics)

widely Accessible and Available

•The last 30 years after the energy crisis, the innovations in products and applications based on R.E.S. are multiplied and developing,

mainly with the introduction and combination of new technologies

Broader and general target:•Clean environment•Abundant and Cheap Energy,•Meeting the energy loads,• where, when, the proper type.

• Quality in life, Continuous Development,• Job creation, • Competitiveness,• Less dependence… Independence,• Recognition ,• Power, • Production of Goods –Wealth-Welfare

Problems:

• Fluctuations on energy availability;

see the case of Solar and Wind Energy,

• Also, low energy density

• RES are abundant everywhere and costless;

• However, Inertia is observed

in the implementation of R.E.S. ,

in large scale plants and applications

•Need for:

1.Education and Training at any level;

• Aim of the efforts

To maximize the Useful Energy (gain)

To minimize cost/unit : installation, operation, service and maintenance

Reduction of loses Increase of Yield, kWhe/kWp High P.R. value of the system

Cost – effective Sizing of the R.E.S. units,

Reliable and competitive operation

All those are issues to be managed only inter - disciplinary
