Perhaps, but will they be able to afford to buy as much power in the future, irrespective of whether it's fossil or renewable?goslow wrote:Anyway, I doubt you will convince many folk to make those changes. Most folk like their electrical power, and preferably not generated in their back yard.
If we undergo a prolonged economic contraction, how many of those manufacturing plants do you think will be around?goslow wrote:Also, what do you suggest for manufacturing and heavy industry, and large buildings such as hospitals.
In any case, there's been a long-term trend of power-heavy plants, like aluminium smelters, moving to locations around the globe with big hydro-power schemes to get a cheap and secure energy supply (the same has happened recently with data centres too). If anything, I think you'll see that process happen both globally, but also within the UK where hubs for tidal power are developed.
We used to locate plants where the raw materials existed -- e.g. Corby steelworks was located in the ironstone mining area of Northamptonshire, only to be demolished when iron ore imports took over from domestic production in the 60s. The same will happen for heavy power users, moving to locations where power is easily available (in that sense it's 'back to the future', since that's how the first factory systems were developed three to four centuries ago).
So, you don't need a grid to support heavy manufacturing industries -- we'll return to the situation that's existed for thousands of years (e.g. http://www.megalithic.co.uk/article.php?sid=6924) where we make certain things in the most suitable location to support their development and then move the goods to where they are used.
Oooh, please, tell me more! I've never heard of being off-grid described as a "risk" before!goslow wrote:But being off grid creates its own risks
