Man, just when I'd bought all those solar panels.
Solar is still worth it. More so at current prices.
Fusion or fission is the cleanest safest way to match demand when wind or sun do not. At least in a nation we're we lack the space to build gravity fed storage.
Only joking. We're offgrid anyway, so unless they can figure out a tiny, cheap and quiet one I can buy off the shelf some time soon I will be solar for a while to come!
Panels have become ridiculously cheap per kwh. I was looking for some more recently and they had halved in price in the space of a few years while everything else has almost doubled.
I'd love to see more innovation in mechanical storage.
Yep most of it is dams and moving water ATM. And while that is efficient. It takes way more space then the UK can spare.
There has been a lot of work using heat storage of late. As we develop more materials etc. I can see this becoming more common. Will always have more loss then gravity. But is much more practice to multi use the land. And build on smaller scale. It is popular in factory situations where heat is often the energy needed. Generate during the day from solar or wind store in huge heat absorbing blocks and release on the night shift.
But use of land is the main problem with all natural renewables. Except maybe tidal. But even that has negative effects on land use. Wind turbines need space beyond the structure. While much can still be farmed. Farming land is also where they are best situated. Due to lack of nearby structures. Solar is a huge land hog. And moving it into our cities. Should happen but to be effective takes a complete redesign,
But the fact that a single car park structure exists that doesn't have the roof covered. Show how little effort has been pushed. Open land car parks should do more. But effect on others light will be an issue. But if you own a building that just parks cars on the roof. It is insane that nothing has motivated you to build out solar over the last 40 years of climate change acceptance.
Spent £280 for 800w for my small boat a year ago. Thinking it was cheap so grab quick. Now half that for the same panels.
It's great isn't it. The panels are getting denser as well which must be great for sailors. What sort of boat do you have?
25ft narrowboat. If not in UK that is a 7ft wide boat/barge designed for our narrow canal system. My brother and I are both visually impaired so the longer ones are not really doable for us.
We spend the summers travelling the 2000 miles of canal network swapping over ever few weeks. I purchased the panals last year thinking they were as cheap as they were gonna get. But we are leaving the boat home to redo the interia over this and next summer. So they are filling my brother living room ATM. 1.7x1.qm each. So will cover most of the free roof of our little boat.
Honestly it's a total guess. But the density of new panals is why I think the price has dropped. All the cheap panals are around 20% efficent but we know 25 of higher has been possible for a good while.
My guess is the price of making those has dropped to the point many chinese etc factories are planning to reequip. And they are selling of the glass 20% stuff while folks are looking.
Once 25% is the price these were 2 years ago. Commercial use will likely move over entirely. Can't imagine the big factories wanting to be stuck on the larger panals then.
But it's just a guess.
That's great you're on the water. I know a few people who have lived on the canals and I have a lot of respect for it. I'm on bit of a mission to sail the seas - wish me luck!
I don't live in it. Although I also know many who do.
My brother and I use it to travel the network for leisure. We are both retired due to health and vision. So we each take it for a few weeks. Moving around the nation. Then get bk us or train to swap over. While the other spends time at home.
That sounds like a great way of doing it :) I've seen some lovely stretches of canal. Do you ever make it over East Anglia?
Not yet. We have only been doing 2 years. And are now staying in Oxford over this summer and next while we redo the interia of the boat.
The flooring is the 1976 original so is starting to have issues with damp.
We also plan to build all the furniture so it can easily be moved to check the bilge etc.
Basically on the way back from Wales last summer we had to stop and get some of the hull over plated.
