“Silver Buckshot” for Energy Transition

How do we transition to a zero carbon energy market? Simon Holmes à Court believes we have much to learn from other countries with more advanced thinking in this space – they have spent the past decade thinking not about whether they should transition, but how. The 2017 Finkel Review created a blueprint to move Australia away from its high-emissions market by ramping up renewables and energy storage uptake. Are we on track?

Light Conversations: Sustainable Solar Energy

The energy we obtain from burning coal today comes from the energy that prehistoric vegetation absorbed from the Sun millions of years ago. But it instead only takes microseconds to convert sunlight directly into electricity. Global electricity consumption continues to accelerate with economic growth and industrial demand. Around 23 trillion kilowatt hours of energy were consumed in the single year of 2018 – the equivalent power needed to turn on 1,800 billion LED bulbs for an hour. To provide our growing population with the level of energy the developed world is used to, we would need to generate 60 trillion kilowatts worldwide. Power plants as we know them cannot satisfy these demands; however, the sunlight energy striking the Earth’s surface in an area the size of Texas alone could provide up to 300 times the total power output of all the power plants in the world. “Solar energy has the greatest potential to fill this energy gap,” says Dr Wallace Wong.
