4 years ago. Rogalands avis Stavanger should position itself as Norway s energy capital not only oil capital. Think long-term - the sun is here to shine for another 5 billion years, Without it the outdoor temperature would have been minus 273 C. Professor Harald N. Røstvik 4

5 years ago. 1878, 1872 and 1960 Approx 140 /55 years ago. Rogalands avis Stavanger should position itself as Norway s energy capital not only oil capital. Think long-term - the sun is here to shine for another 5 billion years, Without it the outdoor temperature would have been minus 273 C. Professor Harald N. Røstvik 5

6 years ago. 1878, 1872 and 1960 Approx 140 /55 years ago years ago. Rogalands avis Stavanger should position itself as Norway s energy capital not only oil capital. Think long-term - the sun is here to shine for another 5 billion years, Without it the outdoor temperature would have been minus 273 C. Morgenbladet Solar energy is the world s fastest growing industry. Norway s biggest stock exchange registration since Statoil is a solar company (REC). Professor Harald N. Røstvik 6

7 In 1981 a solar plane flew Paris to London. In 2015 round the world. EARLY RISERS 1988 Building of the Future Exhibition Stavanger. Chanelle Europe s first modern solar energy autonomous house First European solar Boat Championship in La Rochelle. Since then solar ferries in regular traffic connecting La Rochelle harbour Norway s largest solar heated sports building. Stavanger Squash Center. Professor Harald N. Røstvik 7

14 PERSISTENCE PAYS OFF Professor Harald N. Røstvik 14

15 PERSISTENCE PAYS OFF Solar PV prices fell to 1/100th in 33 years. Now possibly halving prices every five years ; 70USD/Wp 0,7. Professor Harald N. Røstvik 15

16 PERSISTENCE PAYS OFF In 65 years solar PV efficiencies quadrupled (4,5% to 20%). Area need per Watt delivered was reduced to 1/50th. The last three years (2012 to 2015) the reduction was to 1/4th. Professor Harald N. Røstvik 16

17 IEA: SOLAR, COAL, GAS IEA: Wind and solar beat coal and gas as power source. Five years ago solar PV was 8 times more expensive than gas for power production. While coal and gas prices for power production rise, solar prices keep falling. Below the table for power production in 2020 Typical view from a landing plane in Bavaria. Professor Harald N. Røstvik 17

18 GLOBAL SOLAR POTENTIAL A GAME CHANGER Sanyo s Genesis Global Energy Network Equippped with Solar cells and International Superconductor Grids Annula irradiation versus energy reserved and global energy consumption. Professor Harald N. Røstvik 18

19 SOLAR IN NORWAY Huge investment funds like Skagen have for decades talked down the solar potential (Fadnes). Now (2015) the same funds are talkin up solar (Søeberg): 10% of Rogaland county s land area say Jæren would be enough to harvest enough solar PV (electricity) annually to cover 10% of the world s need for electricity. Global horizontal solar radiation (kwh/m 2 ). Kristiansand is similar to North Germany. Professor Harald N. Røstvik 19

33 PERFORMING ARTS CENTER KRISTIANSAND 2004 Watermusic by Tombazis and Røstvik Professor Harald N. Røstvik 33

34 CYPRUS INTERNATIONAL UNIVERSITY Energy autonomous university. The last building to be run by solar is energy efficient using earth ducts to cool ventilation air. Natural ventilation based. In this way the energy need is lowered and the solar PV facades have a hig impact as energy supplier. Now on site being built (2015). Professor Harald N. Røstvik 34

44 AS TIME GOES BY The technological development accelerates. Do you recall the word slide-rule? 2010 This is the one my father used and taught me to use. Which tools our children will use when they get to our age, we do not yet know, because they are not yet invented. The same speed of development will be seen in the sector of energy Professor Harald N. Røstvik 44

45 STATOIL New Statoil Headquarters, Stavanger-region. All the big players tried to get involved finally five were picked including Foster + partners and Snøhetta. Gerth Wingårdh won. Professor Harald N. Røstvik 45

46 From 1991 and my first book to my latest in 2015 is a time span of almost 25. A solar revolution has taken place with solar prices now almost 1/100 of In many ways the future is bright full of hope and sunny. Professor Harald N. Røstvik 46 hnr@telnett.no
