The ten major questionsThinking inside the box... but mainly outside the box!

How?How

much?

Who?

Where?

When?

What?

11

12

Ways to invest in renewable energy

Local levels: new trends

National levels: growing markets

Globally: technology, costs and

markets

Let´s assume

12

13

How much renewable energy?18% of renewables8% traditional; 10%

modern

IEA (1993) = 10% RE in 2030

50% of new electricity from RE in 2011

Sustained Growth (Shell) = 50% RE in 2050

IEA (2011) = 35% RE in 2050

RE will grow at higher rates

More intense close to 2050

Conservative bet: > 35%

15

16

Is RE more expensive?

Common sense says yes, but...16

17

Should consider:

Fuel and technology subsidies

Environmental costs

Fossil fuel price risk

Or less expensive?

17

18

RE will cost less

Innovation +Externalities +

Rationalization =

Decreasing RE prices = RE costs less to the

society

18

19

What is the future of policies?

Countries with public policies supporting RE

2005 = 55

2012 = 120

19

20

Public policies supporting RE

Policies will be

paramount for RE

20

21

Will RE mitigate Climatic Changes?

Scenarios surveyed by IPCC CO2 Concentration

1 – > 600 ppm 3 – 400 - 600 ppm 1 – < 400 ppm

21

22

Will RE mitigate Climatic Changes?

Renewables share on the scenarios

50% - for 450 ppm 77% - for lower concentrations

22

23

RE will mitigate Climatic Changes!

Higher shares of RE will be compulsory for

reducing energy related GHG Emission !

23

24

Do RE need storage?

Common sense says yes, but...24

25

Does RE need storage?

Probably not soon, but breakthrough low cost and high density technologies will be

necessary after 2050

25

26Centralized / distributed grids?

Widely different visions

More local grids

Integration needed

26

27Both will be necessary

Balanced wise

combination

27

28

How much investment?2011 – US$ 290 billion

RE receives morenew power investment

28

29

How much investment?From now to 2035 – US$6.4 trillionAfter 2035 – US$ 500 billion /yr

New financing sourcesand models for the future

29

30

Oil and gas companiesBiofuels, biomass, solar

Wind offshore, hydrogen

30

31

They will play the game!At the moment oil companies start investing at the same rate of others investors, than the RE share will accelerate its growing

31

32

RE is as green as organic food

Sustainability

Green value chains

Corporation green image

Society trend

32

33

Innovation and costs are tiedInnovation, scale andpublic policy are thetripod for the futurelarger share of RE at low cost

33

34

Wind power onshoreWind power onshore grows fast

5 – 16 US cents / kWh

Best projects = < 5 cents / kWh

34

35

Wind power onshoreMultiple innovations

New materials Lower weight Concrete towers Permanent magnet Direct drives Aerodynamics Substitutes for rare earths Information technology Smarter maintenance Cheaper small scale

turbines

35

36

Wind offshore: longer way ahead

Present: 11 – 22 US cents / kWh

Trend 2035: 6 US cents / kWh

Supply chainsNew turbinesFloating foundationsNew system design

36

37

PV: The future of the future

Home: 22 - 44 US cents / kWh

Utility: 20 - 37 US cents / kWh

Best projects: 9 - 13 US cents / kWh

Future: < 10 US cents / kWh37

38

PV: Innovations are on the pipeline

Cell efficiency Thin films Dye, polymer and organic

PV Earth abundant materials Cheaper foundation Cheaper integration38

39

Concentrating Solar Power

Present: 19 – 29 US cents / kWh

Future: 6 – 10 US cents / kWh

Higher temperatureLarger storage capacitySupercriticalDesalinationAir receiversGas turbinesHVDC transmission lines

39

40

Geothermal, a mature technology

Present: 6 – 11 US cents / kWh

Trend to decline

Enhanced GeothermalLow temperature CHPDrilling

40

41

Biomass replacing fossil fuels

8 -17 US cents / kWh Fuel supplies

Technical conversion and pathways

Heating technologies

Bio-refineries

41

42

Biofuels, plenty of innovation

Biomass gasification

Sugar to biodiesel

Cellulosic fuels

Synthetic biology

New feedstocks, like microalgae

42

43

Conclusions RE came to stay It is a matter of choice It is a true green energy Public acceptance Innovation, scale and

policies will make the difference

43

44

To think upon“We can be almost certain that the future will not be a linear growth line from today. We always underestimate the future, which then produces surprises. I’m sure that some people is underestimating the growth of renewables as well.”
