Energy Efficiency is playing an important Role in Saudi Vision 2030
A vibrant society
Kingdom’s wealth lies in its peopleand society and it takes pride inwhat makes it exceptional: Beingthe heart of Islamic faith and itsnational unity.
A thriving economy
A thriving economy for citizens tofulfill their aspirations. Creatingmomentum towards an era ofprosperity through diversification,education and training, employmentopportunities and entrepreneurialdevelopment.
An ambitious nation
Any government needs to evolveand improve to keep pace withrising expectations of its citizens,and provide them with the tools forincreasing their quality of life.
Increase the efficiency of fuelutilization in the electricity generation
and water desalination sectors
Increase HouseholdSavings from 6% to 10% of
total household income
Stimulating innovative industrial solutionsto improve energy efficiency and waste
management.

Investments are classified as“economically viable” if the paybackperiod for the up-front investment isequal to or less than the amount of timean investor might be reasonably willing towait to recover the cost, using the value ofundiscounted fuel savings as a metric. Thepayback periods used were in some caseslonger than current averages but theywere always shorter than the technicallifetime of individual assets.

Develop dedicated PV modules to beused in the Kingdom but also being soldin the world-wide sunbelt
Enable a “Saudi Blue Roof Program”based on the net-metering principle
Establish SMEs for implementation,monitoring and maintenance
Thus, let existing peak power plantscontribute to base load
Additionally, add wind power resourcesas another renewable resource

CSP PV
Dedicated PV modules could be used locally and globally
The Electricity & Cogeneration Regulatory Authority (ECRA)has already paved the way to small roof-top PV Systems

Domestic Energy Consumptionas Share of Production
Domestic energy consumption hassignificantly increased since 2000,and thus reducing share of energyproduction going to exports. Saudi Arabia has implemented
efficiency standards on key sourcesof domestic energy demandincluding vehicles and airconditioners. Air conditioner standards alone are
targeting efficiency improvementsby 35%, saving 47 million barrels ofoil and increasing export revenuesby $2.5 billion.

Your Takeaway
Energy efficiency isplayinga vital role inSaudi Vision 2030
Residential consumersare using~50 % ofelectricity in Saudi Arabia
Most of the electricity isused für air conditioning
A state-of-the-art energy management processcould significantly improve the situation
Energy efficiency measuresin industrieswouldcontribute aswell
Roof-top installed PV could easily be integrated andsupport sustainibility on the lowest level
Energy efficiency measurescould have a hugeimpact on the economy
Any commentsor questions?
