Victoria can simultaneously solve Melbourne’s future sewerage crisis whilst building a sustainable carbon credits sector. A common sight for Melbourne’s residents in the 1850’s would have been carts full of “nightsoil” trundling down Flemington Road. Melbourne subsequently built one of the world’s best municipal water systems, supporting the quality of life its residents enjoy today.

In 2020, Victoria still relied on coal for 69% of all electricity generation; however, the Victorian government has set a target of 40% renewable energy production by 2025 and 60% by 2030. If we harness our plentiful resources, we could be leading the charge in renewables. Led by the Gippsland Tech School, students are being challenged to design an entire city powered by renewables like hydrogen, solar, and wind energy.

“One of our research goals is to create transparent solar cells with a natural appearance so that they can be used as windows that generate solar power.” For solar window applications, a perovskite film with a thickness of no more than 600 nm is sufficient to achieve maximal light absorption. But reduced thickness also reduces potential power conversion efficiency.

When the Moon passes between Earth and the Sun, thereby totally or partially obscuring our view of the Sun, we witness a solar eclipse. It happens due to ‘crazy coincidence: the Moon is 400 times smaller than the Sun, but it’s also 400 times closer.’ This means that, from Earth, the Moon appears large enough to block our view of the Sun. The Moon does not cast a shadow over the entire Earth at once, but rather, is seen over a particular spot.

Australia had installed more renewable generation infrastructure in the three years leading up to 2020 than the thirty years prior. While these are positive steps, Australia also has the highest per-capita greenhouse gas emissions of any other advanced economy, and is nowhere near close to reaching its Paris Agreement goals. Victoria’s Gas Substitution Roadmap is a step in the right direction.
