Kerosene transition to off-grid lighting solutions – Situation Analysis

Some 1 billion people do not have access to clean and sustainable light sources because they are not connected to national grids. The only accessible option for some is kerosene lighting and cooking (Kaygusuz, 2012). The major population who have no access to light is concentrated in Sub-Saharan Africa with around 598 million people living in darkness and relying on conventional energy sources like the kerosene. Kerosene lighting has detrimental […]

Denmark’s Sustainable Energy Programs Inspiring Transitions Around the World

Denmark’s transition to renewable energy is an inspiration to countries around the world, looking to implement their own sustainable programs to decrease reliance on fossil fuels. With more than 45 per cent of Denmark’s total electricity powered by wind in 2016, and an entirely self-sustainable island off the country’s coast, the stage is set for Denmark to continue on its path to eliminate the need for other sources of energy. […]

Proposal from Tesla Encourages Discussion About Renewable Energy in Australia

Finally, the Australian government is considering the potential benefits of addressing the country’s energy crisis with solar batteries – thanks to a $33 million bet with billionaire tech entrepreneur Elon Musk. In the past, Prime Minister Malcolm Turnbill said a “rush” to increase Australia’s generation of renewable energy would result in more expensive, less reliable power. Following a proposal from Tesla’s Elon Musk, Turnbill is changing his tune, even tweeting […]

Peer-to-Peer Energy Market Emerging as a Reality for Australia

With the rise in popularity of renewable energy alternatives, more and more households are becoming energy “prosumers” – meaning they are both consuming and producing energy. Start-up companies are beginning to tap into this market, creating platforms that allow these prosumers to sell their excess energy to other consumers in the area. Peer-to-peer energy markets are popping up around the world, with start-ups in the United States, Europe, New Zealand, […]

Free Geothermal Power from Earth’s Heart

I have yet to get my mind around the idea that Earth’s inner core is dense iron and nickel, surrounded by boiling liquid like the stuff that comes out of volcanos. Nevertheless I find the potential power of it awesome, although it does remind me how transient life is on earth. The ancient Greeks were not far off when they believed everything – including you and me – is a […]

The Endlessly Renewable Power of the Tides

The water flows high up the beach when the moon is directly overhead, as happens on the far side of planet. The rhythm is predictable with a spacing of approximately 12 hours and 25 minutes. Half way between these points, the water level is at its lowest. There are subtle variations because of local factors. However, the power is always there. This knowledge is not new. In approximately 150BC the […]
