I got my solar panels installed back end of last year. Am I expecting it to "pay itself back quickly"? No. What I do hope is that the cost of it will come down, causing more people to buy and encourage renewable energy.

 

I'm not naive to think we'll go totally renewable in my lifetime (early 30s now) but if we could make it so we use fossils for certain jobs and renewables for others, that's great. I'm even willing to sacrifice some TV/ electric time for it, if it means that hospitals and things can continue to run. 

 

This news about wind power is great and the quicker we get more efficient, the better we'll become.

"Our overheating world is likely to break a key temperature limit for the first time over the next few years, scientists predict.  Researchers say there's now a 66% chance we will pass the 1.5C global warming threshold between now and 2027."

 

Keeps getting closer, faster. And therefore, so will the effects of such an increase.

 

Edit: not reading the comments on that article is self care. Reading them gives possibly one of the finest arguments for epistocracy.

:Astronomers have discovered what they believe to be the largest explosion ever detected. 

 

The explosion is more than 10 times brighter than any recorded exploding star - known as a supernova. 

 

So far it has lasted more than three years, much longer than most supernovae which are usually only visibly bright for a few months."

 

Intriguing.

It's a bit misleading to say "so far it has lasted more than 3 years", because it is presumably long finished.  It started 8 billion years ago.

I suppose they should have added "from the frame of reference of the Earth" to be absolutely correct, but then I think that might have confused more people unfamiliar with the nuances of relativity than satisfied people familiar with them.

…As opposed to the largest implosion at LCFC which has just lasted two years so far.

Water companies have apologised and pledged £10bn to clear up spills and improve sewage systems to help prevent future spills. Apology suggests they’re culpable, but it’s you and I that pay for the £10bn in higher water bills.

Guess what? It's the Nordics leading the way again.

 

Like any market though, as it matures, prices will come down. Here's hoping the UK can follow suit ASAP as it does.

As clear a case as any of individuals making economic decisions.  Same with Solar in Australia.  Provide grants and the people will invest where the return makes sense.

Well, yes.

 

Now we need more examples of it in more places. Rapidly.

Oh look, they've now confirmed that we're going to pay for their fuch up.

 

Seriously, I grew up in a Tory household and am a poster child for their ideal voter but my main thought now is just to nationalise anything that the majority of the public use - water, transport, energy and internet.

You'd think it'll be absolutely necessary for the government to get involved to some degree.

 

I can imagine a world a few years down the line where, bills have gone up, current chief execs have sailed into the sunset and those that replaced them are giving the same nonsense apologies we've heard before.

I had solar panels installed in 2013 and the installation costs were recovered about 7 years later.

 

We were told they had a lifespan of 25 years by which time I will be 89!!

Considering that's a decade ago and it took only 7 years to recoup, and the tech will only have matured in terms of such things by then, that's not bad at all.

 

Your wallet should thank you. The future will thank you even more. :thumbup:

I got mine here in Oz about two and a half years ago and I reckon it will have paid for itself in about a year’s time. Obviously a bit of a different equation here of course.

And that shows how the tech has matured in a short time in of itself.

 

It really needs to be on as many buildings in as many locations that it would be suited to as possible as soon as possible. And it has an advantage over Gen III/IV fission in it can be set up in a rather more timely fashion.

 

Solar, wind and tidal are all areas the UK needs to be building infrastructure in at extreme speed.

We so wanted them, but we were told not possible on our roof due to skylights . :mad:

"The US space agency has enlisted a second billionaire to help it put astronauts back on the Moon.

Nasa is already working with Elon Musk's SpaceX firm on a descent system based on its novel Starship rocket that will touch down as early as 2025.

It has now also awarded Amazon.com founder Jeff Bezos a contract to build a landing craft to take a crew down to the lunar surface later this decade.

His Blue Origin company will produce a more conventional-looking vehicle."

 

NASA hedging their bets, I reckon. Just hope we get those three landings - if not more - before the end of the decade.
