Loy Yang A power station burns brown coal – an inefficient source of electricity that doesn’t stand a chance competing against renewables.
The key to reducing green hydrogen costs in the future lies mainly in technological improvements.
A study of real-world disasters shows home solar and storage could keep the lights on and the air conditioner running during many outages, but not all.
A technique called ‘energy arbitrage’ allows owners of local ‘microgrids’ to make a profit by designing the network to buy cheap power, store it and sell it back at a higher price.
By 2025, factories are on track to churn out enough silicon to produce the equivalent of all installed solar – every year.

The US is a latecomer to offshore wind development, but President Biden has set big goals for expanding it. The Gulf of Mexico has good conditions and a large offshore energy industry.
The important change sends a direct signal for more investment in renewable energy, and comes not a moment too soon.
While a US transition to renewable energy by 2030 is possible, streamlined policies with clear goals and incentives are necessary to get there, says an industrial engineering professor.
East Kalimantan province possesses enormous potential for clean energy.
No electric vehicle maker currently meets all the bill’s supply chain requirements, not even Tesla. One big reason: China.
While Congress considers new renewable energy incentives, Texas’ sprawling wind farms tell a story about renewable energy ownership in the US – and who benefits from subsidies.
