Yeah I’m not disagreeing that natural gas should also be part of the short term solution. But I also think that solar is going to be a comparatively much bigger part of the long term solution, albeit at a more expensive upfront cost. Homes that are generating their own electricity with solar panels can’t install natural gas panels to do the same.

This can't possibly be true. I thought Alberta is going in the wrong direction emissions wise?

Solar efficiency is still terrible, so with more advancements it'll likely become much better.

But because it needs the sun to function, and the simple fact is that the sun doesn't shine all day, so you don't actually have consistent power production all day, it means it can't be used as baseload power.

Therefore it is a fill in solution only. Anyone who thinks differently is delusional.

Absolutely, but to say it can't play a significant part is also dillusional. Cooling loads are a perfect one to be roughly matched to high solar producing conditions in our climate.

But yeah, all aboard the nuke train - woowooooo!

Uk switched from coal to gas and increased renewables too and is inching close to 50% of power from renewables. Emissions were down 16% in 2023 all due to gas consumption decreasing due to more renewables coming on board

Wait, wait, wait, I thought we were told switching from coal to natural gas is NOT the solution?
Just want to help out, I found the problem with the statement.

I think if you were to ask any real environmentalist they would say;

We need to get off coal as fast as possible gas or not, overbuild wind and solar, develop pumped hydro and gravity towers, improve syngas and direct carbon extraction tech. We need to build warehouses for half spent batteries that aren't efficient enough anymore, but are paid down as capital assets and still store energy. We need to encourage massive advancements in Ag-tech with the explicit goal of re-wilding land. We probably need to seed the sky with reflectors during dry heat waves. We need to accept and start building out Nuclear. We need to do it all and more. And with the likely path towards about $20T in annual economic lose to climate impacts, it's uneconomical not to do it all.

I'm seeing proposals for Wind/Solar hybrids + energy storage that are looking at bidding into capacity auctions. While 100% of the output wouldn't be dispatchable, it would be considered baseload power.

They are close on price, but not quite economic yet.

Unfortunately our government wants to virtue signal instead.

What specifically is holding back LNG in Canada? Pipelines? Tanker bans? Regulations? Lack of investment confidence? Everyone complains that we’re not doing anything but they seem to not be doing anything about it. Where is the business pressure on this?

Are they economic with a price on carbon (I know you're talking about in the US where there is no carbon price)?

Battery prices are absolutely tumbling as are PV modules due to insane oversupply. CATL has said their prices for their lithium phosphate batteries will be USD$56/kWh this year. For context, it was $128 in 2022 and $107 in 2023. PV module prices are already 20% lower in April than even just December. Nuts!

The US has high tariffs of course for these cheap Chinese products, but this will mean Even more aggressive build out globally. Solar PV manufacturing capacity is expected to be 1100 GW in 2024 and 1300 GW in 2025. Last year 400 GW were installed and at last 550 GW this year. Crazy oversupply with warehouse full and companies having negative margins just to keep factories open. Batteries are even worse. Batteries prices will fall by 50% this year due to an absolutely massive oversupply with a still giant pipeline of new production capacity to come online.

I don't think it'll be long before we see unsubsidized "baseload" PV/battery +/- wind being very competitive

University of Queensland researchers have built a generator that absorbs carbon dioxide (CO2) to make electricity.



Quote:
“This nanogenerator is made of two components: a polyamine gel that is already used by industry to absorb CO2 and a skeleton a few atoms thick of boron nitrate that generates positive and negative ions,” Dr Wang said.
Quote:
“We could make a slightly bigger device that is portable to generate electricity to power a mobile phone or a laptop computer using CO2 from the atmosphere,” Professor Zhang said.

“A second application on a much larger scale, would integrate this technology with an industrial CO2 capture process to harvest electricity.”

Pretty cool stuff. Obviously very early, but if it can be developed, and it looks fairly cheaply, this could have many applications.

More bad news. We're now expected to see more warming more quickly than previously predicted. Dave Borlace explains.
