Snow Fences Generated Power This Past Winter in Minnesota

Minnesota tried out a neat idea to upgrade their snow fences along highways to generated electricity through solar panels. The idea of a solar fence itself isn’t new, but the application of it in this context is. Unsurprisingly, the results were exactly what you would think of a solar project: it works and the current pay off is about decade, plus increasing the scale of the project reduces the time it takes to recoup costs. Compare that to your average snow fence that has zero ROI. When thinking of a robust power grid these small-scale projects can add up to a very powerful solution.

The solar snow fence generated 10 to 30 kWh per day—enough energy to power an average household—with a payback period of approximately 11 years.

For managing blowing and drifting snow, the solar snow fence outperformed the traditional snow fence due to its lower porosity and higher stiffness. Solar snow fences had the best economic viability if they operated under a PPA.

The length of the fence is a critical factor for economic viability, as those measuring at least one mile will benefit from economies of scale. Design improvements such as longer solar panels, fewer posts and a better connection between the solar panel and the steel post will lower costs and potentially reduce the payback period to five years.

Ireland Ditches Coal

Ireland joins the ranks of other countries that have officially ditched coal, yes coal. Coal that 20th century power source that gave us global warming which too many places, like Canada, still use. We used to say that the future is renewable energy and it’s no longer the future: it’s today. Renewables are cheaper, more reliable, and not victim to the whims of an authoritarians who randomly attacks other countries. Renewable power gives Ireland predictable energy costs. It’s only a matter of time that no country uses coal so it’s in every country’s interest to get on the renewable generation as soon as possible.

“Ireland has quietly rewritten its energy story, replacing toxic coal with homegrown renewable power,” said Alexandru Musta??, campaigner on coal and gas at Europe’s Beyond Fossil Fuels.

“But this isn’t ‘job done’. The government’s priority now must be building a power system for a renewable future; one with the storage, flexibility, and grid infrastructure needed to run fully on clean, domestic renewable electricity,” Musta?? warned.

Jerry Mac Evilly, Campaigns Director at Friends of the Earth Ireland, appealed to the government to ensure oil backup at Moneypoint is kept to an absolute minimum and ultimately decommissioned. He also appealed for the government to prevent further development of data centers, which he said are increasing Ireland’s reliance on fossil gas.

African Solarpunk is Real

The future will be powered by renewable energy and the continent of Africa is an example of what’s to come to other continents: solarpunk. Solarpunk is the vision of a world entirely powered by renewable, carbon negative (or just neutral), and ultimately living in concert with a a global ecosystem. That seeds of a solarpunk future are being planted throughout Africa. Ironically, the lack of an established and robust power grid makes for increased opportunity for renewables. Sales from handheld solar lamps to full solar installations are on the rise. When there aren’t vested interests holding back renewable adoption then people go straight to cheaper, more reliable, renewable.

And here’s what nobody outside Africa understands: Sun King has 50%+ market share in their category. They’re not scrappy startup. They’re a dominant infrastructure provider.

This would be like if one startup owned 50% of U.S. home solar. Except the impact and the TAM is bigger because there’s no incumbent grid to compete with.

Ontario Just Made it Clear: Get Solar or Pay More

Homeowners in Ontario are about to pay a lot more electricity with no sign of rate increases stopping anytime soon. The far right Conservative government has torn up renewable developments (at a cost to taxpayers of $231 million) and done very little other than make announcements about nuclear power. You’re probably wondering where the good news is in all of this. Surely, a government hellbent on destroying the planet and people’s pocketbooks isn’t good. To spin the news: there has never been a better time in the history of Ontario than now to get on renewables. If you own a home then you should be investing in solar, wind, or geothermal to save tons of money (and the planet); otherwise you should at the very least get better insulation so you pay less for heating and cooling.

Ontario’s electricity market needs a deeper conversation, one that goes beyond time blocks and rebates.

How do we make energy fair? How do we protect households from volatility? And how do we incentivize solutions—like rooftop solar, battery storage, and smarter appliances—that put power back in people’s hands?

These aren’t fringe questions. They’re central to the future of energy in Ontario.

Because if the last few years have shown us anything, it’s this: betting on lower hydro bills is no longer a safe strategy.

Solar Soars Above Coal as World’s Biggest Source of Electricity

Believe it or not there are places love coal so much that they seem to despise their citizen’s health and wellbeing. The rest of the world is moving to renewables rather quickly and this year marks is the first that solar is now the biggest single source of electricity. That’s right: just one source of renewable electricity has overtaken the most harmful source of electricity. The future is 100% renewable!

Solar power delivered the lion’s share of growth, meeting 83% of the increase in electricity demand. It has now been the largest source of new electricity globally for three years in a row.

Most solar generation (58%) is now in lower-income countries, many of which have seen explosive growth in recent years.

That’s thanks to spectacular reductions in cost. Solar has seen prices fall a staggering 99.9% since 1975 and is now so cheap that large markets for solar can emerge in a country in the space of a single year, especially where grid electricity is expensive and unreliable, says Ember.
