With Yes Solar your solar geyser will pay for itself!
“Last year I installed those solar panels in my house for the geyser, that energy-efficient kind. Today, I got a call from the contractor who installed it. He complained that the work had been completed a year ago and I still hadn’t paid for them. Hellooo … just because I’m blonde doesn’t mean that I am automatically stupid. So, I told him
Subsidies vir sonkraggeisers droop op!
Die installering van laedruk-sonkraggeisers in die Baai is voorlopig gestaak omdat Eskom se subsidies daarvoor opgedroog het. Die sondraggeisers is n Eskom-projek en word deur hom gefinansier. Sowat 30 586 geisers is al by regeringshuise hier aangebring. George Ferreira, van die maatskappy wat die geisers installeer, het gesê hulle het al 120 000 huishoudings voorsien. Ferreira het op n onlangse komiteevergadering oor infrastruktuur, ingenieurswese en energie gesê die projek is gestaak weens geldnood en hy weet nie wannneer dit hervat sal word nie. Volgens Mnr. Ferreira spaar huiseienaars maandeliks sowat R30 aan krag met laedruk- sonkrag-geisers. Hulle het egter heelwat probleme ondervind tydens die installering. “Talle huiseienaars wat by hul huise laat aanbou het se dakke voldoen nie aan die standaarde nie en ons kon nie installasies doen nie. Ons het ook enkele lekke ondervind omdat vullertenks wat plaaslik vervaardig en SABS-goedgekeur is, foutief was. Ons moes 6000 van die vullertenks vervang. Sommige foutiewe krane is vervang. Van die geysers wat verkeerd geïnstalleer is, het van huiseienaars se dakke afgewaai.” Dié probleme het veroorsaak dat die maatskappy nie soveel wins gemaak het as wat hy aanvanklik bereken het nie.

Load shedding – again?
With winter not in full swung yet South Africa’s electricity shortages are so severe that Eskom is regularly cutting supply to some of its major clients to prevent the entire supply network to collapse. During peak times last month Eskom had to use it’s gas turbines, which should only be used during emergency situations. While Eskom and Ms Dipou Peters, Minister of Energy, maintains that no outages are expected, the market still reacted sharply last week to rumours of South Africa possibly facing a re-occurrence of the load shedding crisis of 2008. Me Hilary Joffe, Eskom’s head of communications, admitted that Eskom’s power reserves was so low the last year that scheduled maintenance work had to be postponed. The current load on the national power network is under severe stress. The situation was exacerbated by the explosion of the Duvha power station at the beginning of the year, resulting in a loss of 600MW in generating capabilities. The 600MW is enough to supply the city of Bloemfontein during peak hours. According to Mr Mike Rossouw, chairman of the Energy Intensive Users Group (EIUG), it happens more regularly that supply to some aluminium smelters and Eskom’s bigger industrial customers has to … Continue reading

Grahamstown: Limited Water
“Serious water shortage in Grahamstown causes some areas to have access to water only one hour per day. It is especially rural settlement Vukani that are being hit by this the worst. During a public meeting earlier this week held by The Movement for Unemployed People, it became clear that the only hour water would be available is during the middle of the night. Around 50 people, mostly woman, from the Vukani Location attended the meeting. Prof. Denis Hughes, the Director for Water Research at Rhodes University acted as chairperson for the meeting. Both the Makana Municipality’s municipal manager, Me. Ntombi Baart and Mr. Dabula Njilo, director of Technical and Infrastructural Services were expected to attend the meeting to explain to the public what the state of the situation is, but none showed up.” Die Burger, 26 Nov’10 – Anna-Karien Otto Let this not be said from your town one of these days. Try to start changing your lifestyle and think different about water and the usage thereof. Contact Water Rhapsody to give you a quote on greywater re-use, recycling your pool’s backwash water, saving the amount of toilet flushing-water, being prepared to harvest rainwater etc. Do what you can … Continue reading

Interesting Facts about Electricity
A spark of static electricity can measure up to three thousand (3,000) volts. A bolt of lightning can measure up to three million (3,000,000) volts – and it lasts less than one second! Electricity always tries to find the easiest path to the ground. Electricity can be made from wind, water, the sun and even animal manure. Burning coal is the most common way electricity is made in the United States. The first power plant – owned by Thomas Edison – opened in New York City in 1882. Thomas Edison invented more than 2,000 new products, including almost everything needed for us to use electricity in our homes: switches, fuses, sockets and meters. Benjamin Franklin didn’t discover electricity – but he did prove that lightning is a form of electrical energy. One power plant can produce enough electricity for 180,000 homes. Alternative Energy The bicycle is the most efficient form of transportation known. It uses five times less energy than walking. B.C.’s forest industry obtains 25% of its electricity from biomass — in this case, the waste material from their own industry. A system of distribution and transmission lines brings electricity to southern Manitoba through 70,000 km of lines. That’s … Continue reading

Interesting Facts about Electricity
History The first windmills were developed in Persia in about 600 B.C. About 200 years ago, Alessandro Volta discovered that when two strips of different metals were put in a sulphuric acid solution and connected with a wire, electricity began to flow. Voila! The first electric battery was developed! Think of him the next time you pick up your battery-operated CD player or Game Boy. In 1879, just over 100 years ago, Thomas Edison invented the first light bulb. (Thomas Edison didn’t invent the first light bulb – but he did invent one that stayed lit for more than a few seconds. Think of the incredible changes it has brought to our current world! The first windmill to produce electricity was in Denmark in 1890. In the past, frightened sailors voyaging at night saw ghostly phantoms of bluish light dancing on the masts of ships. Called Saint Elmo’s fire, the light is actually a form of static electricity. In 1986, an accident at Chernobyl, USSR, sent radioactive material into the atmosphere and raised concerns about the production and storage of radioactive waste. What is a kilowatt hour? When we buy petrol, we’re charged per litre. When we buy electricity, we’re … Continue reading

Ways to reduce your electricity bill Step three:
Get a geyser blanket The exact savings are hard to predict, but fitting a geyser blanket around your geyser and insulating your hot water pipes is recommended, says Palmer, as these prevent heat loss when the geyser is switched off. Geyser blankets range in price from R90 to R400 – only buy those that are SABS-approved, Eskom-endorsed and flameproof. DIY kits are available but it’s easiest to ask a plumber to install the blanket, at a cost of roughly R250–R450 per hour (it shouldn’t take longer than an hour). For more information, go to www.eskomdsm.co.za.

Ways to reduce your electricity bill – Step Two:
Switch to gas Gas is used extensively for cooking and heating in other parts of the world, but here in SA, we have no pipeline gas, says Palmer. You will need to buy a Liquid Petroleum Gas (LPG) canister which fits your appliance. A refundable deposit is required for the ongoing use of the canister and you refill it at your nearest gas outlet (see www.totalgaz.co.za; www.afrox.co.za; www.easigas.co.za). Remember, as LPG is 100% derived from oil, its price fluctuates with the oil price. Says Terence of The Gas Experts (www.gasexperts.co.za ), you can purchase a good, safe four-burner gas hob for under R2 500. For a family of four living in a basic townhouse, a 9kg bottle of gas can last up to nine months, costing R200 a year to run the hob. A medium-sized gas water heater, retailing for R3200, will use a 48kg bottle of gas (costing R790) approximately every two and a half months. Installation of a gas stove and geyser will cost around R4500 (excluding the bottles). To keep warm, gas heaters and fireplaces are cost- and energy-efficient.

Ways to reduce your electricity bill – Step One:
Opting off the grid To live off the electricity grid, says Duncan Palmer from the Centre for Renewable and Sustainable Energy Studies, you need a number of solar panels, a wind turbine (depending on where you live), an inverter and some batteries. ‘Solar energy from the sun is harvested with photovoltaic (PV) panels, which convert the solar energy directly into electrical energy. An electrician wires the inverter into your existing electrical reticulation circuit.’ ‘To sustain normal electricity habits and supply a regular house, you will need about 6kW of PV panels, which will cost around R210 000,’ says Riaan Meyer, from the Centre for Renewable and Sustainable Energy Studies at the University of Stellenbosch.‘Adding the inverter, batteries and other components will up it to R500 000 – pricey, but you’re investing in 20 years’ worth of electricity.’ But while an entire solar power system may be out of reach of most people’s budgets, there are some simple steps you can take to lighten the load. According to Eskom, a household’s largest electricity expense is water heating, which typically accounts for 40–50% of the monthly bill. Installing a solar geyser system to cater for the needs of a family of four … Continue reading
What kind of droughts does South Africa experience?
A brief synopsis of drought in South Africa since 1960 -2005 Introduction The rainfall climate of South Africa is one of great variability. Seasonal rainfall percentage deviations since 1960 demonstrate wide fluctuations about the long-term average and it is in this context that large rainfall deficits must be assessed. Between July of 1960 and June of 2004, there have been 8 summer-rainfall seasons where rainfall for the entire summer-rainfall area has been less than 80% of normal. A deficit of 25% is normally regarded as a severe meteorological drought but it can be safely assumed that a shortfall of 20% from normal rainfall will cause crop and water shortfalls in many regions accompanied by social and economic hardship. Discussion All but the south-western and southern regions of South Africa rely on summer rainfall, which normally falls between October and March, the summer season. Rainfall is heaviest in the east and decreases westward. For convenience the rainfall season is taken to run from July until June of the following year, but rainfall outside of the summer season is usually insignificant. The consequence of rainfall being confined to six months of the year is that most crops can only be grown during … Continue reading
