Green Energy

This looks like an interesting project:

I have no background in evaluating how legit battery tech is. Anyone know anything more about the project or that type of battery?

A deal being offered in my area is:

• they cover the roof with insured PVs, which remain the property of the supplier for 30 years. The supplier installs and maintains them at no cost. They repair any damage. Homeowner pays absolutely nothing.
• no batteries. Homeowner’s consumption is gratis when the sun is hitting. Any unused energy goes back to the grid.
• homeowner gets no credit for what goes back to the grid, but they still benefit from free energy they consume when the sun is out and ultimately a reduced energy bill.
• after 30 years, the panels and everything become the homeowner’s property. (The panels are likely worthless at that age anyway)
• if the roof needs to be renovated in the future, the supplier removes the panels and reinstalls them at no cost, but the homeowner will have some fees for things like scaffolding.

The supplier profits from some kind of green certificates from the gov.

Seems like a no-brainer, on the edge of too good to be true. So I’m trying to decompose this to look for traps and anti-features.

It seems to boil down to homeowners trade roof space for energy in return. 30 year contract.

It complicates any plans to go off-grid. A homeowner can buy the PVs at a price that decreases every 5 years, starting at €850 each in the 1st year. So €8500 for 10 panels. Then they can exit the contract and go off-grid in the first 5 years for that price. That price is where the deal seems a bit sour. A PV should only cost around ~€60, correct? Isn’t €850 an extortionate price for a PV? If someone knows they want to go off-grid in the future, I get the impression they’re better off rejecting this deal and buying their own panels.

They install a few different meters. So I wonder if it’s really just fancy metering. E.g. wouldn’t it make sense to feed all solar power into the grid, then just pause or offset the homeowner’s meter for energy they consume from the grid while feeding the grid?

Fusion technology is likely far from powering a grid — if it ever will. Dozens of fusion startups have launched anyway.

“Adjusting for the differences in capacity factors among solar, nuclear power, and natural gas, the new solar capacity added in 2024 is likely to generate seven times as much electricity as the new nuclear capacity and about five times as much as might be expected from the new natural gas capacity,” SUN DAY explains

The SUN DAY Campaign based its calculations on FERC data, which show that 105 units of solar power went into service in December of 2024 alone, for a total of 4.369 gigawatts. Between wind, solar, and biomass, renewable energy accounted for 86.9% of added capacity in December, with natural gas making up the rest with a relatively small contribution of 717 megawatts.

“Solar’s share of U.S. generating capacity is now 10x greater than a decade ago while wind’s is more than double,” SUN DAY emphasizes, noting that FERC expresses a “high probability” that new additions of solar capacity will total more than 9.1 gigawatts between now and December 2027, with wind coming in second with more than 2.3 gigawatts.

After a Chinese export ban, can America get gallium and germanium from Canada — or will tariffs get in the way?

The industry can now make 50 gigawatts of panels in the U.S. Solar cell factories are coming next, but may be hindered if Trump kills a key tax credit.

Wind power is gradually rising to the challenge, and in the residential market, it is as popular as solar power. Meet the Liam F1 Mini Urban Wind Turbine by Archimedes – a miniature wind turbine specially developed for city use.

This small and revolutionary product delivers energy to home roofs and generates up to 1500 kWh of free electricity per year — and it is silent. The Liam F1 is quickly proving to be a strong contender for solar energy solutions and a worthy contender for solar panels for consumers who are concerned about sustainability and the environment.
