This year we’re celebrating Earth Hour’s 10th anniversary. A lot has happened since we first switched off in 2007!
Here are 10 big wins that have helped change climate change and 10 great Aussie ideas that could help solve climate change. To #jointhefuture, here are tips for how we can change the way we live for a cleaner and brighter future.
This year we’re celebrating Earth Hour’s 10th anniversary.
A lot has happened since we first switched off in 2007, so here are 10 big wins that have helped change climate change
Australians consume a lot more per person than in many other countries. The food, energy and water we use, the timber and plastics that we depend upon – everything we do uses natural resources and produces waste. The measure of this impact on the environment is called our ecological footprint.
Making simple changes in our daily lives – at home, in our shopping choices and even how we travel – can reduce your carbon footprint and save you money too.
See how you can reduce your ecological footprint by adopting new habits that are softer on the environment.
Keep an eye on these 10 Climate Solvers: homegrown technology that could help reduce our ecological footprint.
New ways with food
By 2050, it is estimated that global food food will increase by 50%, presenting a great challenge to develop more sustainable methods to feed the planet.
In Port Augusta, SA, a 20-ha greenhouse is growing tomatoes using hydroponics, and sunlight to produce freshwater from saltwater. No need for soil, and pesticide free.
Each year we generate over 50 million tonnes of garbage.
An Australian company EarthPower has found a way to capture methane from food waste, which can be used to produce electricity. This reduces the amount of waste going into landfill, generates green electricity, and the nutrient-rich product left behind makes high-quality fertiliser!
Did you know that about 95% of the components in your old mobile phone can be recycled?
Companies such as MobileMuster offer a free service for the recycling of old mobile phones and accessories. Since the program began in the 1990s it has helped recycle more than 10 million handsets.
Cool ways to cool
Heating, ventilation and air conditioning (HVAC) units are one of the highest consumers of energy in buildings.
One cool tech by IP Kinetic uses waste-water to cool the air before it enters existing AC units, reducing the energy needed to cool the air by half, reducing carbon emissions and extending the unit’s lifetime.
Home energy management
These days you can monitor anything with your smart phone, including your household energy consumption, using a Household Energy Management system (HEMs) app!
Many apps are available in the market, including Wattwatchers Auditors, and Eddy home energy app by CSIRO and HabiDapt, which allow people to monitor their energy usage real-time their mobile, switch on and off remotely, and potentially save money on your electricity bills..
CSIRO have also found a way to reduce the production of methane - one of the world’s most potent greenhouse gases - in cattle production. By mixing atype of seaweed t grown easily in Queensland into the cattle’s diet, they reduced methane production by 99%. That’s right, they found a way to make cows burp and fart less methane.
New types of Batteries
Batteries and storage systems are potentially the answer to help stabilise distributed solar energy generation: the key is to make them as cheap and efficient as possible.
New batteries such as aluminium-graphene batteries are poised to disrupt the traditional lithium-ion battery market. These batteries have the potential to offer more power, more storage, and lower recharging times.
Harnessing wave energy could potentially contribute 11% of Australia's energy needs by 2050.
Companies such as Carnegie Wave in WA have convert ocean energy into renewable power as well as produce freshwater through desalination.
In 2015, Perth best mates and surfers Andrew Turton and Pete Ceglinski came up with Seabin, a sustainable solution for marina docks pollution by designing an automated rubbish and oil bin with a pump. The Seabin Project is now in production and n could reach 17 markets in late 2017.
Staying ahead in solar technology
How about printing some solar power? CSIRO and the Victorian Organic Solar Cell Consortium have been developing thin, flexible and lightweight solar cells using printable ‘solar ink’. These innovative new solar cells will be able to be used in windows and even consumer packaging.
