One, Two, Three: Get to Know your Solar Power Systems

August 23rd, 2012

Every type of Solar Power system has one thing in common; they are all designed to harness clean renewable energy, effectively reducing environmental damage and lowering electricity expenses for those who invest in them. However, these systems are also diverse in their size, structure and suitability; it’s important to know which type of solar power application would be the most appropriate for your property, and why. It may sound like a complex decision, but the first step is simple; know what solar power systems are available, and how they would affect your home and office.

Essentially, solar power systems fall into three main categories, and each of these are suitable for different working and living environments.

The Next Step to Renewable Household Energy: Solar Power Systems

August 17th, 2012

solar power systemIn an effort to go green, many home owners are installing Solar Power systems in order to produce renewable household energy. Although this is a move in the right direction, many people are missing an important step in converting to green energy, and that is saving energy first.

Conserve Energy First

In previous articles we have been concentrating on how to conserve energy in the home, either by changing wasteful habits or by installing energy saving appliances such as LED Lights, gas heaters and Solar Water Heating systems. Although everyone should be practicing green habits in the home in order to conserve natural resources as well as earnings, energy conservation is the vital prerequisite to installing solar power systems. In short, only once you have conserved energy can you begin to create it. Read the rest of this entry »

Pool Pumps: Pumping Water or Pumping Up your Energy Consumption?

August 6th, 2012

So it’s the end of the month and you’re standing there scratching your head while holding the electricity bill, “Why am I paying so much?” You’ve checked the geyser, you conserve heat by way of geyser blankets and pipe insulation, you boil only as much water as you need and you have already installed LED Lights throughout your household; but did you know how much energy pool pumps use?

The sad fact is that many people don’t realise the cost of pool pumps extends long after installation and without monitoring its operation you could be spending hundreds every month on electricity that you don’t really need. Before you go and rip out your entire pool to save money, there is some good news – you can prevent these large bills from drowning your dreams for sustainable living in some very practical ways.

Out of Sight, Out of Mind:

The first problem with swimming pool pumps is out of sight means out of mind. When you leave for work, in winter or on holiday are just some of the instances where we may even forget they’re running; they could be on for as long as 12 hours a day which is simply not practical or necessary. The operating costs of pool pumps go through the roof when used in this way, so monitor their use; they can still fulfil their function at half the output. Read the rest of this entry »

Energy Saving just got Cooler with Solar-Ready Fridges

August 5th, 2012

A refrigerator is an integral part of any household, yet it can also prove to be among the least environmentally friendly of appliances. It goes without saying that fridges and freezers are among the hardest-working appliances in the home; they run all day, every day, keeping food and beverages chilled or frozen. This means they are high-consumption appliances, raising your electricity costs and your household’s carbon footprint. Pardon the pun but that’s just not cool… it’s time you turned to solar powered refrigeration.

Hot Investment with Cool Savings

We all know a solar kit can be an excellent household investment, but purchasing one simply to lower your refrigerator’s consumption can be very costly. By purchasing a solar compliant refrigerator you can save yourself a good deal of money that would otherwise be spent on solar equipment – up to R20 000 in fact – and you’ll be one step closer to running a fully energy efficient home.

The Lighter Side of Life: Why LED Lights are the Obvious Choice

August 3rd, 2012

led-lightsWe pay them very little attention until they go out. We feel cheated when we have to make a supermarket run dedicated to them and we certainly get frustrated when we buy the screwy one instead of the clippy one. These issues are basically eradicated when changing to LED Lights. Besides their clear economic benefits and longevity, LED light bulbs trump halogen lights in all departments. Here are just a few qualities that make LED’s the clear solution in sustainable lighting.

Most of us are under the impression that if we’ve changed from halogen to Compact Fluorescent Lighting (CFL), we can be secure in the knowledge that we’re living under the “greenest” light there is. That was the case some time ago, before LED lights saved the day, even though CFLs themselves have come a long way since being introduced to the market.

Use Gas Water Heaters for Energy Efficient Water Supply

August 1st, 2012

solar kitIt’s a well known fact that geysers make up a large portion of the total energy consumption of a home or office. However, efforts to implement a more efficient water heating system are often cast aside, even though water heating is considered the easiest green installation and a first step to making your home more energy efficient. Gas water heaters are an attractive and efficient alternative to high consumption electrical water heaters and can also be used in addition to your Solar Water Heating system, as a backup warm water supply. Another advantage of a gas water heater is that it reduces a building’s reliance on Eskom’s services. This article describes the technology of gas water heaters and its application in the home and office, outlining further benefits of a gas water heating installation.

Green Technology: Gas Water Heaters

Gas water heaters use liquefied petroleum gas (LPG), most commonly in the form of propane and butane, which are safe and environmentally friendly fuel sources. The greenest form of ignition is the innovative hydrogenerator ignition, which requires no batteries or manual start up. Water heating is initiated as soon as a tap is opened, offering an instantaneous hot water supply. Like battery powered gas water heaters, hydrogenerators are safe, efficient and quick to use.

Is the DEA Head Office as Green as it’s Painted?

July 20th, 2012

It was all about “walking the green talk” in Pretoria yesterday, at the ground-breaking ceremony that marked the start of construction on our country’s first-ever Government-owned sustainable building. The building, situated in Arcadia, will serve as a head office for the Department of Environmental Affairs (DEA), and it’s estimated that construction will be completed within the next two years.

The idea of a major sustainable building project, funded by the National Treasury and designed to fit Climate Change Policy specifications, is certainly an uplifting one – but after taking a closer look, one is forced to ask the uncomfortable question: is this R8-billion building really as green as it could be, or should be?

Eskom Proposes Five Year Tariff Increase Plan: How Will This Affect Households?

July 2nd, 2012

eskomEskom has initiated the application for the third multi-year price determination (MYPD 3) with the National Energy Regulator of South Africa (Nersa), which will determine nationwide electricity prices for the period starting 1st April 2013. The current MYDP 2 for the period April 2011 end March 2013 denotes a massive increase of 25% per annum; fortunately the electricity increase was reduced by 25% to 16% in 2012, approved by Nersa. The proposed MYPD 3, which will span a period of five years as opposed to three, has put forward an electricity tariff increase of 16% per annum. This rate is far above inflation and will continue to make electricity an unaffordable necessity for many South Africans. With all these figures in the pipeline, how will these electricity hikes affect our household energy bills?

Keep the Cold at Bay – 4 Sustainable Tips for Winter

July 2nd, 2012

Keeping the cold at bay remains the mandate of most South Africans now that we’ve reached winter’s peak. With electricity price hikes on the rise and Eskom’s plea that individuals cut down at least 10% of their power consumption, sustainable.co.za has put together 4 simple energy-saving tips for the conscious-minded consumer.

Top 4 Eco-Friendly Winter Tips

  1. Break Out the Hot Water Bottles: At the first signs of a cold breeze or rain, our natural inclination is to pull out our electric blankets. But did you know that there are energy-efficient alternatives to this unnecessary bed-warmer? Not a necessity, there’s no need for an electric blanket when you can snuggle up under your duvet with a hot water bottle and a warm cup of cocoa.
  2. Utilise Gas Appliances: Gas heaters, gas ovens, gas solar kits – gas is a great substitute for electricity. If you can’t afford to purchase a gas stove, our range of eco cookers are based on the principle of insulated cooking and are suitable for a wide range of recipes and ingredients. For individuals looking to fire-proof their homes this winter, our bio-powered two plate stove is a safer alternative to traditional Paraffin stoves (which are favoured by a large number of South Africans).
  3. Choose Solar Power: Geysers are usually a home-owners biggest source of energy consumption. Using power to maintain your hot water temperature throughout the day, these electricity guzzlers can easily be replaced with solar geyser systems that will drastically reduce your household’s power usage. Many South Africans are reluctant to convert to solar power in winter because of the shorter days and minimal sunshine, which is why sustainable.co.za also offers solar heating kits that come with gas water heaters. These kits ensure that your geyser will not run out of hot water at any time of the day, and are still a great substitute for geysers that solely rely on electricity.
  4. Light Up with LED: A simple way to reduce your home’s electricity bill, LED lighting is one of the most cost-effective energy saving products – using only 6 watts of electricity per bulb. Some locals have come to associate LED bulbs with a garish, stark lighting affect. Here at sustainable.co.za, we offer a range of bulbs that provide a variety of hues for every preference.

The Bottom Line?

Cutting down on your power consumption is really simple. Keep in mind that there’s always a sustainable alternative to your electrical appliances – and at minimal costs. Implementing any of the above tips will guarantee that you lower your electricity bill, keep warm, and make a valuable investment in green initiatives.
