The 1909 incident may have cost the industry decades of progress – and the planet huge amounts of damaging carbon emissions.
An ambitious clean energy transition requires more of the metals and minerals used to build clean energy technologies.

The demand for the minerals needed to build clean energy technology currently exceeds the available supply. If this issue continues, governments may find it hard to reach their clean energy targets.
Placing vertical solar panels on farming land allows for energy production and higher yields.
Using agricultural land for both solar and food production presents huge opportunities for Canadian farmers, especially in Alberta.
There’s a consensus that extreme hydrological events will increase throughout the continent. This will lead to growing issues with power system reliability.

China is a major investor in Latin America’s renewable energy and critical minerals like lithium, but countries like Chile are also taking steps to secure their own clean energy future.
A heater with a 300-litre tank can store as much energy as a home battery at a fraction of the cost. Being able to store surplus solar energy at the right times helps grid stability and cuts emissions.
Consumers must do their homework before determining whether a company is actually green.

Look for hidden trade-offs, political contributions and what businesses are not telling you.
Australia’s renewable energy transformation will require a huge amount of energy storage. We need Snowy 2.0 to succeed.
As the energy revolution gains pace, huge numbers of PV panels are already going to landfill. Many are still usable and even those that aren’t contain valuable materials that shouldn’t be discarded.
Agrivoltaic farming — growing crops in the protected shadows of solar panels — can help meet Canada’s food and energy needs.

Canada can meet its carbon emission reduction targets, make food cheap again and open up a gigantic trade surplus with the U.S. by shading farm crops with solar panels.
Making the green energy transition a success requires governments to pay attention to environmental factors and socioeconomic imperatives.

While this prominent and well funded project has gone into voluntary administration, those enthused about rapid decarbonisation and Australia’s renewable energy export potential need not despair.
The good news is the world’s coal use has peaked – and will soon rapidly decline. Australia is leading the way, and the rest of the world must soon follow.
How long should a solar subsidies, or any subsidy, last?
