History could repeat itself if China turns AI into an abundant, commodity-driven industry. Should we be worried about AI’s new land of plenty?

Solar energy is associated with intermittency issues, as it only generates electricity when the sun shines. Certain PV systems can provide cost-effective power reserves for storing electricity.
In Canada, agrivoltaics could produce enough electricity to eliminate the need for fossil fuels on the grid entirely, using less than one per cent of the country’s agriculture land.
Older rooftop solar systems are being scrapped – often well before the end of their useful life. Establishing a product stewardship scheme is part of the solution.
Solar energy can help grasslands weather droughts in the semi-arid American West.
The energy return on investment for wind and solar technologies in New Zealand is becoming comparable to hydropower.
Yes we need land for solar panels, wind farms, batteries, pumped hydro, transmission lines and so on. But the amount of land is surprisingly small, when you do the sums. Here’s why.
New research shows densely populated countries in Southeast Asia and West Africa could harvest effectively unlimited energy from solar panels floating on calm tropical seas near the equator.
Only 13% of US solar industry jobs are currently in manufacturing. The Biden administration hopes the sector will grow fast, but that might not be so simple.
Earth’s floating solar power capacity has grown one-hundredfold in the last five years.
Our research identified three key lessons.
South Africa’s well positioned to adopt electric vehicles but this isn’t a solution in itself because the vehicles would still depend on electricity generated from carbon-emitting coal power stations.
Australia is in the midst of a solar energy boom, yet it is lagging behind other countries when it comes to ‘building-integrated photovoltaics’ - solar cells built into the very fabric of buildings.
Small-scale renewable energy projects can power rural areas not connected to the main grid. But investors may hesitate if future electrification remains unpredictable.
Silicon is cheap and a good semiconductor, but it’s bulky and rigid. Using organic polymers as semiconductors could yield solar panels with the physical characteristics of plastics.
Energy experts are getting excited about a proposed solar farm in Kent and what it could mean for a clean energy future.
Solar photovoltaics and wind power are on track to supplant fossil-fuel-based electricity generation by the 2030s. The only thing holding back the renewable revolution is politics.
Our energy system puts consumers more or less at the mercy of business and regulators. What if the future of energy meant putting the power back in the hands of households?
What’s at stake as the Trump administration imposes trade sanctions on imported solar panels? A look at the US solar energy industry, which generates more than twice as many jobs as coal energy.
The price of renewable energy will fall significantly relative to new-build coal in coming decades, making an all-renewable electricity system more desirable, both economically and environmentally.
