3. Conclusion



Introduction
Since the first realization of gas in the Emirates, the economics of the country has raised significantly

Foreign people are attracted either for visiting or for living in the UAE

Result:
An exponential population growth (rise in electricity consumption)
The current UAE
renewable energy supply

The majority of UAE’s energy is consumed for
electricity
(residential) and
water distillation
The annual total global solar radiation at different surface slopes
[0, 5, 10, 15, 20, 25] deg. from the horizontal plane

Assessment of UAE Renewable Energy Resources

The wind speed for one year simulation
Plot of the ambient temperature and the temperature values at the thermal collector inlet and outlet
Solar Flat Plate Collector

Discuss the effect of different collector slopes [1, 25, and 50] deg. on the collector useful heat gain

Solar Flat Plate Collector
Discuss the effect of
doubling the mass flow rate
through the collector on the collector outlet temperature and the collector useful heat gain

Introduction
Problem:
1-
Natural gas is depleting with time "anticipated to survive until the mid of 2020"


2-
Natural gas increases GHG

Solution:
Utilize Renewable energy sources

Solar radiation vs. different slope angles
Renewable energy presents the keys of the UAE’s future for an alternative clean sustainable energy and economics diversification for power plant productions.

From TRNSYS:
1. PV cells
2. Solar collectors
3. Wind turbine
The orientation of these panels is important in gaining useful energy
High useful energy gained from 25 deg.
Due to the maxim exposure to the sun
Annual wind velocity Plot
Ambient temperature Plot
Outlet temperature Plot
Useful heat gain in flat plate collector in different slopes
Annual outlet temperature with doubled mass flow rate Plot
Annual useful heat gain in flat plat collector Plot
Only slight difference in useful heat gain
From 8.09E+06
To 8.19E+06
Gas consumption in UAE
Electricity
60%
Water
Distillation
25%
Industry
15%

Stationary
Tracking system
The direct radiation of a beam in UAE was found to be 400W\m^2 in 2007
Efficiency
PV cells
To maximize the turbine efficiency in high elevation:
Increase diameter
Increase height
In 2011 PV had the highest cost with 5800$\kW
Manufacturing Part
Transportation
Maintenance
PV cell
No GHG emissions during operation
Wind turbines
GHG emissions median is 13 g CO2eq\kW-hr
Solar collector
Solar collectors can reduce almost
200kg of GHG gases
Emission could be due to manufacturing, transportation or maintenance
Life cycle emission median is 35-40 g CO2eq\kW-hr which less than coal & natural gas
Birds are harmed and killed from the blades rotation
Negative visualization impact in modern countries like UAE
Negative impact on habitat due to large land usage
Sunny and dusty weather
So, large amount of water for cleaning and cooling
PV cells
250 W performance sheets based on thin film technology & crystalline technology comparasion
Cont.
Annual total electricity production for PV panel at diff. slopes
25 Deg. is close to Abu-Dhabi's latitude (24 deg.)
Thus more exposure to sun light throughout the year
Crystalline technology simulation
Thin Film technology simulation
Cont.
Efficiency%= Power_out\Rated Power
Wind turbines
Note
: Type used is: wind diesel\Enercon- E40 (46).par & power output is in kW
Annual wind turbine power output
Performance coefficient of wind turbine
Utilization factor= Power_out\Rated power
Rated power= 605000 W * 8760 hr
Power-out (W-hr)
U.F= 8%
