What is Renewable Energy ?
Forms of Renewable Energy

Renewable Energy: energy that comes from resources which are continually replenished on a human timescale
Why Renewable Energy ?
Environmentally Friendly
Jobs and Economy
Energy Security
Solar Energy
Wind Power
Photovoltaic Cells
Solar Farms
Solar Water-Heater
world's first commercial Solar tower
4 years
23,400 MW-h/year
US$ 360/MW-h
11 MW capacity
20 MW capacity
4 years (2006-2009)
48,000 MW-h/year
US$ 360/MW
Direct or Indirect Systems
Passive or Active Systems
First automatically wind turbine built
The first electricity-generating wind turbine was a battery charging machine installed in July 1887 by Scottish academic James Blyth to light his holiday home in Marykirk, Scotland.
The first megawatt-capacity wind turbine in Vermont, USA.
Clevland, Ohio, US
60-ft. tall, weighed 3.6 tonnes
built by Charles F. Brush
12 kW generator
Offshore wind Farms located North Sea off the coast of Belgium
Freeway Structure
Small Quietrevolution
Inside view
biological material from Organisms.
Mostly refers to Plants
As a Renewable Energy:
1) Directly used via Combustion
2) Indirectly as Biofuels
Conversion methods from Biomass to Biofuel:
i. Thermal
ii. Chemical
iii. Biochemical
Wood is most common and typical source of Biomass
how it works
The Hellisheiði Power Station
303 MW electricity
400 MW hot water
Located in Iceland
Malitbog Geothermal Power Station
Capacity of 232.5 MW
Located in Philippines
Wayang Windu Geothermal Power Station
Capacity of 227 MW
Located In Indonesia
Dams (Conventional)
Small or no reservoir (storage) capacity.
Subject to seasonal river flows.
Serves as peaking power plant.
Water coming from upstream has two options:
Tidal Power
Converts the energy of tides into useful forms of power - mainly electricity
More predictable than Wind energy and Solar power.
Classified into three generation method:
A hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods
Often form a part of Pumped Storage Hydroelectricity.
Types of Hydroelectricity
Three Gorges Dam - China
Capacity: 22,500 MW
Itaipu Dam - Brazil & Paraguay
Capacity: 14,000 MW
Grand Coulee Dam - USA
Capacity: 6,809 MW
Used during periods of high electrical demands "Peak Demand"
1) immediately used for power generation
2) Allowed to bypass the dam at once.
Chief Joseph Dam - USA
operated by the U.S. Army Corps of Engineers
1) Tidal stream generator.
2) Tidal barrage.
3) Dynamic tidal power.
Rance Tidal Power Station - France
The world's first tidal power station.
The world's second biggest tidal power station.
240 MW capacity.
Sihwa Lake Tidal Power Station - South Korea
The world's largest tidal power installation.
254 MW capacity.
Robert-Bourassa generating station - Canada
the largest underground power station in the world
Capacity: 5,616 MW

Implementing Green Power in Saudi Arabia
Thank You
The world relies HEAVILY on fossil fuel.
82.8 million barrels consumed every day.
The percentage of fossil fuel Vs. other resources is 80% and 20% respectively.
Environmental Pollution is increasing with fossil fuel consumption.
In 2006, Saudi Aramco Senior Vice President Abdullah Saif estimated that its existing fields were declining at a rate of 5% to 12% per year.
Ghawar, which is the largest oil field in the world and responsible for approximately half of Saudi Arabia's oil production over the last 50 years, will soon start to decline.
Oil Crisis
Future of Renewable Energy
Studies show that by 2030:
Wind power capacity increasing between 4-fold and 12-flod
Solar PV capacity increasing between 7-fold and 25-fold
CSP capacity increasing between 20-fold and 350-fold
Bio-Power CSP capacity increasing between 3-fold and 5-fold
Geothermal Power capacity increasing between 20-fold and 350-fold
1 wind turbine produce enough electricity to power up to 300 homes.
Enough sunlight falls on the earth for just 1 hour can meet the world energy demands for 1 year.
Renewable Energy has now exceeded Nuclear energy
The jobs in Renewable Energy will number 12 million
In 2010, US$ 243 billion was invested in Renewable Energy.
