Power behind the scenes

This gallery contains 4 photos.

Hin Wah, our Communications Programme Manager, wrote a lovely piece for the Green Times magazine about our wave turbine installation at the Two Oceans Aquarium. A continuous wave is needed to keep the kelp and other plants in the aquirium alive. Project 90 teamed up with the aquarium to design and build a wave turbine which could create this wave without using electricity. Continue reading

Help Eskom and help yourself

This gallery contains 1 photos.

It seems the whole of Cape Town was affected by the recent load shedding a few weeks ago when Eskom’s coal reserves were soaked by unusually long and heavy rains. Our office didn’t have power for most of the morning, which made me realise how reliant on electricity we all are (and the need for solar panels on our office roof!) But what other options does our country have, which is so heavily reliant on coal? And what can you as an individual do? Robert Fischer gives us some advice and looks at the short and long tem options. Continue reading

Ask An Expert: Cooking with less energy

Q: I think I use a lot of electricity for my cooking. I like to cook meals, which require long cooking times, like beans, stews and samp. What can I do to save energy?

A: Soaking your dry beans overnight before cooking is one way, but some people complain that this would affect the taste. Another way to save electricity when cooking is to make use of the fantastic Wonderbag! It’s actually a kind of donut-shaped pillow, filled with insulating material. After you’ve brought your beans or stew to boiling, put your pot into the Wonderbag, cover it and wait until food is ready! As simple as that. Read what Nontando writes about her wonderbag

The Great Heater Debate

We’re having a heater debate here at the Project 90 office, as winter slowly approaches. Our office is freezing in winter, and despite dressing warmly (hats, gloves and scarves!) we still have a need for heating. Our office has panel heaters as well as gas heaters and we have been debating which is the most carbon efficient way of heating our office. Does it make sense to use the panel heaters when it means having to leave them on overnight to keep the room warm? I remembered that Gary Fahy wrote an article comparing different types of heating, and have re-posted it here. It makes for interesting reading. Continue reading

Wonderful Wonderbags

This gallery contains 2 photos.

Nontando Bonga, our enthusiastic volunteer, tries out a Wonderbag in her home in Langa and is hooked immediately. Not only does it save her time and electricity but it also helps her to reduce her carbon footprint. With Valentines Day coming up, this could make the perfect eco-gift. (Here’s hoping that you haven’t already bought that pink heart-adorned teddy bear imported from China!) Continue reading

Project 90 by 2030 recently launched an online Household Tool to help you identify ways in which you can reduce your environmental impact and save money each month.

With April being family month using our Household Tool is a great way to start cutting carbon at home, and everyone in your family can pitch in and do their bit. Continue reading
