Apropos of nothing, this video shows the transition between the upper two photos. Look at the left at about 3:18 and tell me that's not the best way to cross a city!


And weirdly, even now, our army still has more horses than tanks.

Great link, thanks.

IIRC, Youngs brewery in Sarf London had more space devoted to keeping horses than to brewing. The increase in efficiency that came from the ICE is amazing and I suspect that the leap that comes from genuinely renewable energy plus electric everything will be at least as amazing or perhaps more so.

In 2010, combined wind and solar generation provided just 2.3% of total power generation. But as of last year, those two energy sources alone provided 230 TWh, or 5.6%, out of a total 4100 TWh generated [in the USA].

And that is even with fossil fuel prices crashing.

However without storage there has got to be a limit to the proportion.

Of late electricity consumption has been falling due to improving efficiency but decarbonisation suggests the need to switch from using gas for heating and petrol/diesel for transportation to electricity - how does this energy requirement compare to existing electricity production?

If its going to happen its going to happen in america first (and maybe china close second). Their scale and regulations and pro business pro lets get things done will leave the EU in the dust.

Electric cars with smart charging would be no issue until millions are on the road. The UK grid could take 10 million cars with no additional power stations. The existing fleet would just run at a higher capacity.

However even if new power stations were needed the new CCGTs are so cheap and so quick to build it wont be an issue. One 1GW CCGT could power 2 million cars doing 35 miles a day. @$1 billion for the power station it works out to just $500 per car in capital cost or ~$15 per year over a 40 year CCGT life


There is some way to go before EVs can take significant market share. really needs a compelling $15k model with 100 miles range and the ability to manufacture 10 million units a year. The world is still a long way away from that. However like I said before if there is a chance the Americans with their methods and deep pockets and capital markets will find a way to get it done.
