The biggest surprise was how much electricity my laptop used, mainly because it would often be on for up to 16 hours a day. While the fridge uses 0.425kWh in 24 hours in normal use, the laptop was using 0.720kWh over 16 hours at 45W/h!
It’s almost too outrageous to be true. But you can save 98% of your water consumption simply by adding a nozzle onto your existing taps. Or you will be able to from the end of this year when production of the Altered:Nozzle starts. The new company turned to Kickstarter to help fund the project online… […]
A LED lightbulb is supposed to last for 6 — 12 years and, being rather pricey, they probably do. But this one will need to be replaced after about a year when a single candle will achieve more light than it does. It’s taken less than two months for this bulb to attract the miggies […]
I wanted to run all lights, a power-hungry laptop (something I only discovered after I started), medium-sized fridge, wireless router, solar production & power consumption monitoring equipment, and battery charging for laptop, cellphone, camera and power drill. Could I do all this off one 150W PV panel (costing about R1700)? Be patient, this is an […]
While household dependence on power utilities like Eskom is becoming a thing of the past as more and more households turn to solar energy, the end of oil companies as we know them is also on the cards. Nothing highlighted this more than one news service in the past week: Norway Electric Car Sales Grow […]
One of the early things needed for the house was WiFi — for electricity monitoring equipment and other “smart” elements that might be included. Asking around, most people in the area use PaarlOnline — not always with great satisfaction. This seemed to be echoed in some online forums, where BreedeNet was mentioned as an alternative. […]
After being impressed by solar energy installations for poorer homes in the northern Drakensberg, I was delighted to discover that the biggest urban solar energy project for indigent families is nearby at Ekanini (population about 9,000) alongside Kayamandi in Stellenbosch. The Sustainability Institute’s iShack Project has already provided electricity to over 1,000 homes.
Hot water from the outset was an absolute necessity because I’m not good at cold showers. And seeing I hadn’t worked out all the options, I certainly didn’t have a long-term plan. So I wanted the cheapest, fastest solution which I wouldn’t have any hesitation in just throwing away or recycling after a month or […]
Household electricity for US$1.50 a month, replacing kerosene for lighting at US$10.00 a month.
In the USA, “Smart Homes” are all about convenience and consumption. In South Africa (and much of Europe) there is a far greater focus on sustainability and renewable energy… on being greener. CapeInfo set out to discover the feasibility — and economic realities — of going off the grid. Is saying goodbye to Eskom (SA’s […]
