“Alberta was the home to 75 per cent of all new renewable deployments in the country,” Wilson said. “We were in the midst of a real golden age of investments. People were setting their sights on the province of Alberta to build and operate projects.”
One of the #renewable energy projects cancelled by the #Alberta UCP government was the Peace Energy Cooperative

Hats off to California. Nice job!
A huge sand battery is set to slash the carbon emissions of a Finnish town.
The industrial-scale storage unit in #Pornainen, southern Finland, will be the world’s biggest sand battery when it comes online within a year.
Capable of storing 100 MWh of thermal energy from solar and wind sources, it will enable residents to eliminate oil from their district heating network, helping to cut emissions by nearly 70 per cent.
The battery’s thermal energy storage capacity equates to almost one month’s heat demand in summer and a one-week demand in winter in Pornainen

The Entire Super Bowl Was Powered by Renewable Energy
https://futurism.com/the-byte/super-bowl-powered-renewable-energy
The firm has developed an energy storage system that raises and lowers weights, offering what it says are “some of the best characteristics of lithium-ion batteries and pumped hydro storage”.
When there is excess power - from wind turbines on a windy day for example - weights would be winched up the Pyhäsalmi mine’s 530-metre auxiliary shaft. To generate energy, these weights can be released turning the winches into generators creating either a short burst of electricity or a slower trickle depending on what is needed.
The gravity energy system would be able to store 2MW of power and integrate into the local energy grid.

Recycling the World’s Batteries | Emma Nehrenheim | TED
Battery recycling pioneer Emma Nehrenheim. While batteries are fundamental topowering a sustainable future, their production is surprisingly harsh on the environment.She lays out the science behind a breakthrough in recycling a battery’s core elements, offering a manufacturing solution that could vastly reduce the industry’s environmental impact.

Recently, Portugal actually broke a record for energy production across the globe as it went six full days relying solely on renewable energy.
Advanced nuclear reactors are no longer our grandparents’ nuclear technology, but the American nuclear permitting apparatus hasn’t caught up, Rep. Byron Donalds writes.

What #BigOil knew about #ClimateChange, in its own words
by Benjamin Franta, October 28, 2021
"Back in 1979, #Exxon had privately studied options for avoiding #GlobalWarming. It found that with immediate action, if the industry moved away from #FossilFuels and instead focused on #renewable energy, fossil fuel pollution could start to decline in the 1990s and a major #ClimateCrisis could be avoided.
"But the industry didn't pursue that path. Instead, colleagues and I recently found that in the late 1980s, Exxon and other oil companies coordinated a global effort to dispute #ClimateScience, block fossil fuel controls and keep their products flowing.
"We know about it through internal documents and the words of industry insiders, who are now beginning to share what they saw with the public. We also know that in 1989, the fossil fuel industry created something called the Global Climate Coalition—but it wasn't an environmental group like the name suggests; instead, it worked to sow doubt about climate change and lobbied lawmakers to block clean energy legislation and climate treaties throughout the 1990s.
"For example, in 1997, the Global Climate Coalition's chairman, William O'Keefe, who was also an executive vice president for the American Petroleum Institute, wrote in the Washington Post that 'Climate scientists don't say that burning oil, gas and coal is steadily warming the earth,' contradicting what the industry had known for decades. The fossil fuel industry also funded think tanks and biased studies that helped slow progress to a crawl."

#Pope Francis tells #world to speed up transition to #renewable energy in Apostolic Exhortation
Pope Francis said Earth “may be nearing the breaking point” based on scientific facts and human factors contributing to #climate change can no longer be ignored.
By Ashley Curtin -October 5, 2023
...“With the passage of time, I have realized that our responses have not been adequate, while the world in which we live is collapsing,” Pope Francis wrote in Laudate Deum.
He also warned against “investing too much trust in carbon capture technology” because “it did not address the root human causes of global warming,” EcoWatch reported.
“Some effects of the climate crisis are already irreversible, at least for several hundred years, such as the increase in the global temperature of the oceans, their acidification and the decrease of oxygen,” Pope Francis wrote.
He called the speed of climate change is happening to the world in “one generation — not centuries or millennia” and therefore, called on businesses and “certain countries” to end short-tern interested because climate change can no longer be denied.
Pope Francis also said environmentalists and activist groups are “filling a space left empty by society as a whole.”...
If you're at the North Pole, which way is South?
https://electrek.co/2023/09/20/worlds-northernmost-solar-farm/
A decade ago, our present renewable energy situation was unimaginable. Most projections had wind and solar as niche players on the electric grid due to their relatively high cost. In the US, the reality is anything but. Combined, wind and solar have now passed coal; throw in hydro, and they've passed nuclear, too. In most areas of the country, they're now far and away the cheapest means to generate electricity; the same holds true for most locations around the world.
Despite the changed economics, most countries have fallen behind on their climate pledges, and fossil fuels aren't being pushed off the grid fast enough to get us back on track. While the entire globe is suffering the consequences of climate change, the factors that are keeping renewables from reaching their full potential vary from country to country. What should we be doing to get past these roadblocks?

In a groundbreaking development, researchers have announced a revolutionary breakthrough in #renewable #energy #storage that could reshape the future of sustainable power sources. The #innovation, dubbed "EcoCell," promises to overcome the longstanding challenges of storing renewable energy efficiently and affordably.
#EcoCell employs an advanced nanomaterial matrix, engineered to optimize energy absorption and retention. This matrix enables unprecedented energy density, allowing for significantly longer storage durations without significant loss. Furthermore, the design incorporates a self-regulating thermal management system, ensuring stable operation even under extreme temperature conditions.
Dr. Emily Rodriguez, lead scientist on the project, expressed her excitement: "EcoCell represents a leap forward in energy storage #technology. With its ability to store vast amounts of renewable energy, we could eliminate the intermittent nature of sources like solar and wind power. This could have a profound impact on global energy distribution, reducing our reliance on fossil fuels."
The implications of this discovery are far-reaching. By addressing energy storage limitations, EcoCell could accelerate the adoption of renewable energy on a global scale, significantly reducing carbon #emissions. While practical applications are still in the testing phase, #industry experts are optimistic that this breakthrough will reshape the landscape of sustainable energy production, bringing us closer to a greener and more sustainable future.
