Title: Types of Renewable Energy


1
Types of Renewable Energy
  • Wind
  • Solar
  • Bio
  • Geothermal
  • Hydro

2
Overview
  • Wind Energy found by harnessing wind
  • Solar Energy harnessed from the sun, captured as
    solar radiation
  • Bio Energy from biological sources that were
    living or recently living excluding fossil fuels
  • Geothermal thermal energy that is stored and
    generated in the Earth
  • Hydro Energy found by harnessing water

3
Case Study
4
What is the worlds most energy deprived
continent?
  • Africa

5
How much of the worlds oil is found in Africa?
  • Roughly 9.5

6
Out of 54 countries, how many export oil?
  • Only 4!

7
Africas Electricity
  • Only 3 of worlds electric consumption

Source Energy Transition in Africa
8
Falling Behind
  • Naturally endowed with many sources of renewable
    energy
  • Rely on old technologies
  • Distrust among local communities
  • Expensive

9
What types of renewable energy would be suitable
for Africa?
  • Hydropower
  • Biomass
  • Geothermal
  • Wind
  • Solar

11
Hydropower
  • From 1973-2008 increased production by 246
  • Only 5 used
  • Potential HUGE!
  • Inga River of the DRC
  • http//www.youtube.com/watch?voJxE1i06O38
  • Other potential options as well

12
Biomass
  • Largest consumer of biomass
  • Many uses in Africa
  • Process Heat
  • Gasification
  • Heat Cogeneration
  • Liquid-Fuel
  • Biogas
  • Solid-Fuel Production

13
Biomass
  • Many industries can be used to create biomass
  • Wood-Based Industries
  • Agricultural-Based Industries
  • Can be used locally
  • Excess energy can then be sold

14
Geothermal
  • Mainly used in Eastern Africa
  • Kenya uses about 17 geothermal heating
  • Many countries are building
  • Only heat not electricity

15
Wind Power
  • Best for coastal regions and some interior
    regions
  • Large-Scale wind projects
  • Egypt
  • Ethiopia
  • Morocco
  • South Africa
  • Tunisia

16
Solar
  • One of the most sun-rich regions of the world
  • Limited by costs
  • Only South Africa
  • Egypt planning
  • Small-scale projects common

17
Whats this Mean?
  • Biggest problem Money
  • Potential is there
  • Africa could be a major producer of renewable
    energy

18
Energy Conservation
  • Oil prices have quadrupled in the last four
    years
  • Because of this, policy makers are concerned
    about energy security
  • What is energy security?

19
Energy Security
  • Narrow the guarantee of sufficient energy
    supplies to permit the country to function
  • Broad the assurance of adequate energy supplies
    to maintain the national economy at normal levels
  • What is a normal economy?

20
Normal Economy
  • associated with reasonable economic growth for
    ensuring societal warfare and allowing the
    national economy to function in a politically
    acceptable manor
  • In order to maintain a normal economy state
    leaders have to devise policies that guarantee
    national energy security

21
Energy Security Policies
  • Rationing- attempts to allocate available
    supplies and limit consumption
  • Stockpiling- country sets aside national energy
    reserves to ensure security and hedge against
    abnormal price fluctuations
  • Diversification- attempts to ensure continuity of
    energy supplies by diversifying sources of energy

22
Indonesia
  • Many reasons to be concerned about national
    energy security
  • Self-sufficient in terms of energy supply except
    oil
  • Worlds largest liquid natural gas exporter,
    second largest coal exporter
  • 46 Coal
  • 26 Natural Gas
  • 20 Crude Oil

23
Indonesia
  • increasingly dependent on oil as an energy
    source, pressure on Indonesian Government to
    reduce oil dependency by switching to natural gas
    for industrial
  • Switching from oil to natural gas in the
    electricity sector
  • Government is always promoting renewable energy
    especially biofuels for transportation

24
What are They Doing?
  • 1982 Regulate Energy Consumption
  • stipulating rules on lighting in public buildings
  • use of air conditioning
  • use of electric appliances
  • use of state owned vehicles

25
What did They Do Next?
  • 1991 Save Energy Campaign
  • training sessions on energy conservation
  • invention and manufacturing of energy saving
    tools
  • initiating research devices in energy saving
    technology
  • energy audit system in order to ensure efficiency

26
And Finally?
  • 2005
  • Limit use of air conditioning, lighting,
    escalators, electric appliances in public and
    government buildings
  • requring cars with large engine capacities to use
    non-supstides fuel

27
Conclusion
  • Attempts to reduce dependency on oil and to
    develop renewable energies indicate governments
    seriousness to guarantee energy security
