1 Energy Security in Camps Bay Reliable and uninterrupted power to households and businesses in Camps Bay The threats Immediate and mid term to mitigate based on conservation and renewables Longer term based on renewables in the context of Camps Bay

2 Threats to Energy Security The blackouts of April 2008 will re-occur (Leon Louw of Free Market Foundation) The blackouts of April 2008 will re-occur (Leon Louw of Free Market Foundation) Demand increasing between 8% and 10% p.a. Demand increasing between 8% and 10% p.a. Margin between supply and demand shrinking from 16% (Lakmeerharan of Eskom) Margin between supply and demand shrinking from 16% (Lakmeerharan of Eskom) Eskoms new Medupi coal fired power station expected to be operational earliest 2014; probably 2016 Eskoms new Medupi coal fired power station expected to be operational earliest 2014; probably 2016 Kusile + 1 other (4,800 MW) planned coal fired power stations: insufficient funds Kusile + 1 other (4,800 MW) planned coal fired power stations: insufficient funds Shortfall of between 20,000 and 40,000 MW generating capacity by Shortfall of between 20,000 and 40,000 MW generating capacity by New Nuclear power stations, if ever, earliest 2022; Eskom considers R 250 billion too expensive compared to coal-fired.

5 Measure and Plot your own power usage Consider installing solar power water heating, LEDs, timers, energy pumps etc. Review the swim pool filter times THREE it's a magic number Yes it is, it's a magic number Because two times three is six And three times six is eighteen And the eighteenth letter in the alphabet is R We've got three R's we're going to talk about today We've got to learn to Reduce, Reuse, Recycle (Jack Johnson; the singer) Implement energy saving mechanisms. They make economic sense

6 Some Conservation Examples!! Recycle things. Recycling an aluminum can to produce a new one requires one-tenth of the energy needed to produce one from scratch. Paper factories use far less energy to make paper from old newspapers than from wood pulp. Recycle things.

Avoid foods that take a lot of water and energy to produce or transport, such as meat and processed meals. Use bottled water sparingly. For one thing, its thousands of times more expensive than water from the tap! Tap water is safe to drink, and you can fit a filter to purify it further if you want. Bottled water consumes energy in production and marketing, and in some countries many of the plastic bottles end up as litter and dont get recycled. Use bottled water sparingly.

When you make a hot drink, boil just the amount of water you need. Dont fill the kettle to the top if its not necessary! When you make a hot drink, boil just the amount of water you need.

Showering takes four times less energy than bathing Showering takes four times less energy than bathing Households are estimated to be responsible for 30% of electricity consumption. So if we all save electricity, it will make a big difference. Households are estimated to be responsible for 30% of electricity consumption. So if we all save electricity, it will make a big difference. When you need to replace a light bulb, buy an energy-saving one: though they are more expensive to buy, they last much longer and use about five times less electricity than conventional bulbs, so in the end they save you a lot of money.

Dont leave your TV, stereo and computer on standby – this is the mode when a little light remains on. On average, a TV set uses 45% of its energy in standby mode. If all Europeans avoided the standby mode, enough electricity would be saved to power a country the size of Belgium.

Also, dont leave your mobile-phone charger plugged in when you have finished charging your phone – it continues to consume electricity even if the phone is not attached!

7 Climate Change and Economics

8 Pakistan August 2010 Death Toll > 2,000 Over 20 to 25 million (15% of total population) displaced> disease etc Threat of a failed state>>terrorism, drugs, crime etc>>security costs increase Aid in USD Billions paid by taxpayers

9 Russia August 2010 Temps > 40 deg C; Hottest in 130 years

10 Wheat shortages expected, despite reserves>Bread Prices set to rise South Africa imports 1/3 rd of its wheat requirements (40% from Germany) World Barley prices rise > Higher beef and poultry prices, beer

11 South Georgia and the king Penguins Glacier Erosion >> higher sea levels (17cms since 1900) Plan for 100 cms rise in sea levels by the end of 21 st Century, (Bindschadler Emeritus Scientist NASA If so, 8 out 10 worlds largest cities will have to move!!

12 Camps Bay June 2009 Restaurant activity disrupted and business losses Repair costs to streets and infrastructure comes from our pockets via City RATES Flood threat from storm surges, spring tides; beach emasculated Will there be a next time?

13 Conclusions of the Stern Report The evidence shows that ignoring climate change will eventually damage economic growth. Our actions over the coming few decades could create risks of major disruption to economic and social activity, later in this century and in the next, on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century. And it will be difficult or impossible to reverse these changes. Tackling climate change is the pro-growth strategy for the longer term, and it can be done in a way that does not cap the aspirations for growth of rich or poor countries. The earlier effective action is taken, the less costly it will be.

14 South Africa a dirty polluter South Africa ranks 12th in carbon dioxide emissions from the consumption of fossil fuels, with million tons of CO2 in 2006 (EIA, 2008). South Africa ranks 12th in carbon dioxide emissions from the consumption of fossil fuels, with million tons of CO2 in 2006 (EIA, 2008). South Africa Ranked 29 th in GDP 2006 (Economist 2009). South Africa Ranked 29 th in GDP 2006 (Economist 2009). South Africa Ranked below 70 in GDP per capita. South Africa Ranked below 70 in GDP per capita. South Africas plans to build more low grade coal fired power stations exacerbates the CO2 emissions South Africas plans to build more low grade coal fired power stations exacerbates the CO2 emissions South Africa and its communities need to embrace with urgency renewables (sun, wind, waves etc) South Africa and its communities need to embrace with urgency renewables (sun, wind, waves etc)

15 Solar Resource Mapping in South Africa Tom Fluri March 2009

16 Average annual wind at speed 10 m above ground (m/s) Kilian Hagemann, University of Cape Town (2008) Wind can produce 35% of SAs Electricity Wind generated energy could cost 30% less than energy from Kusile

17 The Waves and Tides off Camps Bay

18 An Inclusive Solution and Objectives To support and engage with the resource conservation programs of the City of Cape Town by reducing CBs reliance on the GRID; making power more affordable to those less fortunate than us. To encourage CB residents to implement energy saving mechanisms and introduce more renewables at household and business levels. To establish advisory services for CB households and businesses for energy optimization. To determine to what extent CB as a community could embrace renewables (wind, sun, waves, tides etc); even feeding into the GRID To establish communications with CB residents via lists, meetings, projects, expert lectures, Round Tables, Podcasts etc. To foster support from and engage with other CB representative institutions (CBRRA, CBW etc)

19 Contact Details Please consider to join our group, we need additional expertise Roy Bermeister: ; Martin Diessner: ; Roger Trythall: ; Web address:
