Fascinating Facts about Energy
Science Energy cannot be created or destroyed. It can only be converted from one form to another. Find an elastic band, and stretch it out. The stretched rubber band has potential energy. If you let it go, it moves and has kinetic energy. Have you ever wondered how you might get a hot air balloon to float up and down? How would you launch it? How would you get it back to earth? The balloon rises by warming up the air inside it. It descends by letting the air inside it cool down. It all works because of heat energy. Electricity travels at 300,000 km/sec. If you travelled that fast, you could travel around the world eight times in the time it takes to turn on a light switch. The energy produced by the atom-splitting of one kilogram of uranium is equivalent to the burning of 1.3 million kilograms of coal or 1.35 million litres of oil. People run on energy too, and food is our fuel. The unit we use to measure expended heat energy is the calorie. Calorie expenditures comparison: Lying at ease – 1.5 cal/min Tennis – 7 cal/min Playing drums – 4–6 cal/min Golfing – 6 … Continue reading

Metro faces severe restrictions – Car washes under the loop.
The necessity of saving water is still in our faces, just as we thought it might be the beginning of the end with the resent rains we had. But just the opposite is becoming a reality. At Water Rhapsody, we want to urge the public to start another thinking mode than what they were used to. Not just during or because of restrictions, but as a general way of thinking. Let us not be so narrow minded, that the availability of water are no concern to us at this stage of our lives, and we think we will be gone by the time it really becomes a problem. We have a system called the Poseidon Advantage, where the grey water from car washes are going through a cleaning process, and re-using the same used, but clean water to wash the cars again. Car washes are being targeted to invest in systems to conserve water, for their demand of washes might increase significantly during these droughts. Have a look at this article in the Port Elizabeth Express by Monique Vermeulen on the 3rd of Nov: Despite much need rain over the last three weeks, the region’s water crisis continue to worsen … Continue reading

Water Rhapsody Ecopreneur talks to World Leaders
Werner Neuhoff, Ecopreneur from Water Rhapsody- South Africa, will be joining leaders from 70 nations in Montréal, Québec during 13-15 October for a World Leadership Conference that will draw women heads of state, corporations and enterprise, as well as members of the diplomatic community, women policy-makers, decision-takers and opinion-leaders on five continents. An anticipated 800 – 1,000 leaders for this global dialogue that will focus on Water, Wealth & Power for the Eco-Century. As we confront a growing scarcity of the world’s most indispensable resource, the International Women’s Forum (IWF) will convene in Canada (13-15 October 2010) to explore and better understand what’s at stake — drawing together from our global membership, leaders of influence from outside the traditional realm of the “water community”. Hearing from the world’s leading experts, advocates and catalysts for change who will address the World Conference, their global membership will be challenged to test the boundaries of possibility for a new era of improved access to and utilization of water resources. Werner Neuhoff, a South African born entrepreneur, would be presenting to this global audience on October 15, 2010 at 8:35 am in Montréal for the Plenary Program – Ecopreneurs: The Blue Gold Rush.

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

Benefit from SWH Rebates while you can
Eskom generates about 95 percent of the electricity used in South Africa. The company has been battling with electricity shortage since January 2008, but its problems date a decade earlier and are due to lack of investment in new capacities and in updating the existing power stations. Last year, Eskom increased its tariffs by 31 percent and asked for 35 to 45 percent annual increases for three years in order to scrape together about R400 billion needed to build new power plants. However, in February 2010 the National Energy Regulator of South Africa (Nersa) approved lower increases: 24.8 percent for 2010/11 financial year, which will bring the average Eskom electricity price to 41.31c per kWh; 25.8 percent for 2011/12, bringing the average Eskom electricity price 51.68 c per kWh; and 25.9 percent in 2012/13, making the average Eskom electricity price 65.06c per kWh. Eskom will use part of the money it gets from the higher rates towards increasing its solar water geyser subsidies, from about R2,500 to about R7,000. The cost of subsidizing solar geysers is lower than the cost of building a new power station. With the new subsidy in place, almost half of the cost of a solar … Continue reading
