G7 leaders agree to phase out fossil fuels end of century
Discussion
It could be the end of the piston as we know it. Coming up to 2100, this forum may end up being generator heads or fuel cell heads.

My initial response was that 85 years is longer than I thought I'd give it.
Then I realised that it'd probably take that long to acheive development and widespread adoption of alternative technologies for heavy shipping, air travel, haulage and power generation- presumably combustion engine powered cars will have long since gone out of production.

So the only way this can be achieved is Electric or Hydrogen cars. The electric cars need to be charged so unless Wind, Hydro or Solar power stations become much better at producing electricity then it is down to Nuclear. Then however there is a the problem of all the protesters complaining against nuclear. Im all for Nuclear power and the other forms but nobody will ever be happy with the end result.
When I was at school just shy of 20 years ago we where told that by 2045, fossil fuels would of all been extracted. I think I got lied too. Saying that thou the combustion engine has only really been around for the last 100 years so god knows what sort of energy would of been developed in the next 85 years.

...and Hydrogen needs electricity to split water into H2 and O2 - which are then recombined to generate electricity...? No, perpetual motion hasn't been discovered yet. More losses, more electricity.All of these are just ways of transferring energy from a primary source (solar, nuclear, fossil, wave, wind) to where it is required for conversion into kinetic energy. There are various losses and inefficiencies in every step along the way. We can use batteries as temporary storage, we can use hydrogen, we can use compressed air. They're just ways of converting electricity into stored energy.

"lied to" is a bit strong. That was the genuinely-held belief at the time. We were running out of oil. Since then, there's been more sources found and - more importantly - ways of getting at what was previously uneconomic/unfeasible to extract.There will always be new ideas and better way to do things.Some bright spark somewhere will be working on something which will benefits us all.
Let's get writ of people starving of shortage of food first.Clean drinking water a sustainable decent live for the poorest people.Just my vieuw on it.

I was taught in geography in the late 80's that world oil would run out by the millennium
And we would all be driving Sinclair c5's big brother that hadn't been made yet
Oh and the Amazon rainforest would be almost gone due to McDonald's cattle ranches
Well they were almost right with that one

It's easy. The ONLY constant energy sourse that comes without any nasty side effects is the SUN. You know, that big shiny thing in the sky that comes out 1 day per year, usually in July, for summer. Solar thermal power plants they are called. Info here:-

Except it's only 50% of the day, on average?https://en.wikipedia.org/wiki/Solar_power_tower
There is no constant renewable sources apart from geothermal. Wind and tide are good as far as we go in the UK -> what use would solar towers be to us in winter? Edinburgh gets 7 hours daylight in December with Inverness getting 6:30!
