Re: Electric Vehicles
My new gas boiler goes in on Thursday, the current on has lasted 18 years. It still works but has deveoped a leak, BG fixed it and 2 days later it started leaking again, So time to go.

ps was meaning to look into the grants available in our area for energy efficient home improvements. Already have cavity wall insulation and adequate loft insulation, although I was contacted about retro installation of insulation in partywall cavity as that acts like a flue for heat escaping at the top of the cavity. Would like that doing. |

The £20K plus needed for ground source heat pump + another £5K for horizontal pipe loop or near £10K for vertical pipe loop ( if your ground is suitable for ground source, not all areas are ) has a massive payback period. Problem with 300mm+ of insulation in loft is that you can no longer keep anything up in the loft, and not even walk across it safely because you can't see where the rafters are, I just filled between the rafters and boarded the loft over - after all whats the use of having a loft if you can't stored stuff up there ? If the roof ever leaks the insulation will soak up the water and get that heavy the ceiling will fall down.

Re: Electric Vehicles
The amount of gas storage ( storage not supply ) that we have in UK has been vastly reduced in the last 3 to 4 years, we are now virtually working on 'just in time' supply of mainly from Norway and up to 20% of gas from liquified gas tanker ships from around the planet. This comes at a time when gas is being used in huge quantities to bail out renewables unreliability. We didn't get rid of sailing boats until we had fully functioning reliable steam ships, and got rid of steam when other forms of propulsion became reliable. We didn't ditch propeller aircraft until we had reliable jet engines. We have however pretty much ditched fossil fuels well before we have any reliable alternatives.
Here is an well known environmental activist who has grave doubts about rollout of renewables - exactly the same doubts that I have had for years now. Even that bastion of greenies California uses a lot of fossil fuels when the sun goes down to keep the lights on. Renewables can best be described as fuel savers when they deign to contribute to the grid, they are not the answer - and unless we extract our digits and get some decent reliable base load generation we are in for many problems. https://www.americanexperiment.org/2...t-save-planet/ https://climatechangedispatch.com/to...co2-was-lower/ .

California - I used to live a few miles from the San Onofre nuclear power plant - it went off line to be upgraded and, unfortunately, when powered back up the heat exchangers proved to be unsatisfactory so the plant was shut down again and the decision made to leave it closed. The Diablo Canyon nuclear power plant sits directly over a major earthquake fault (as does nearly everything in CA) and PG&E (Pacific Gas and Electric) are planning to decommission the plant shortly. California's power problems are partly political - in the 90s it was cheaper to buy electricity from neighboring states and then the Enron scandal hit. California was desparately short of power and the neighboring states screwed CA by jacking the prices - gotta love capitalism. The problem in CA is still NIMBYism. UK: https://www.theguardian.com/business...year-uk-energy Does the UK have a coherent long term plan, does it in fact have any plan? I hope so. This is the main problem: https://www.independent.co.uk/news/u...-a9373221.html If the majority of Tory members don't believe in man made climate change and the MPs represent their constituents (ha ha) then where's the impetus for change? We are building, or rather the French and Chinese are building a new nuclear power plant in Somerset and talking about building one in Suffolk. Whether these are good value or will ever be completed is moot. Finally, I live in a rural county which, you'd think, would have good air quality. No. The Trent valley and Drax coal power stations lower my air quality - so goodbye to coal asap. You can put a wind turbine in my garden.

Re: Electric Vehicles
Drax has been burning biomass for a number of years and is phasing out coal within months if not already.. They're also planning to run two CCGTs

Re: Electric Vehicles
Regardless of how much solar/wind is built and comes on line, without energy storage in place we still need fueled generation - Gas, Nuclear, Biomass, Coal, without it we are back to rubbing sticks together to make fire.
Renewables are a nice topup in the grid when it's sunny/windy, it may even at some points make up 30 ro even 40% of the total generation but that rarely lasts an hour before a cloud comes along or the wiind dies down (or it gets too windy). Without the capability of being able to press buttons to generate electricity we are stuffed, full stop. Renewables as they stand without storage are a joke, I hate to think of the cost/mass of an energy storage medium capable of storing enough energy and able to release it in a controlled fashion to replace fossil fuels, if it ever went bang, hell that would make a nuke look like a raindroip. The answer lies in science fiction - Cold Fusion, Space Based solar arrays, alient power sources - without them, it's back to burniing something we can store to make the energy we need. Look at the hunt for lithium to make batteries for cars, imagine having to compete with car manufacturers for batteries for electrical storage as a Grid backup, you thought Nuclear was expensive? lol |

Re: Electric Vehicles
My employers have a massive battery storage array... An Electrical Engineer I would call a good friend worked a lot on the project.
It's mahoosive for the 10mw it provides* *Their remaining coal fired units are contracted until 2023/4 respectively but there's tenders in the works to replant with gas Last edited by Chris_SVS; 12-01-21 at 01:57 PM. |
