100% renewable energy in 40 years IS possible....

Quote:
New research suggests the whole world could switch to renewable energy sources using current tech in just 20 to 40 years. It would cost no more than current energy, and would have big economic and eco payoffs. The only barriers are down to social, business, and political inertia...

There's nothing more difficult to predict than the future.

Re: 100% renewable energy in 40 years IS possible....

Sure .... but 40 years hardly qualifies as some kind of uthopic The Future, no?
It's a tangible quantity of time, where a tangible effort can lead to tangible results, no?
I mean - how long did it take to build cathedrals, after all....?

Just saying...

It's also 'possible' to eradicate poverty and diseases and war in 40 years, but not bloody likely to happen, is it?

There's the rub... immenses sources of energy in Wind/Solar/Wave , but nothing to store it yet...

Use it, don't store it (e.g server farms)?

If there's a will there's a way, etc, etc, etc
The key buzzword is "inertia". Then add "lobby" and "vested interests"

Actually, Lithium ion battery is one of the choices.

Need to store it for when the wind dies and the sun goes down. Wave power seems to be the best way forward...constant and reliable.

Re: 100% renewable energy in 40 years IS possible....

Frankly, all this tree hugging utopia is all a joke. Has anybody every thought about what would happen if we really would have a green earth? things would get really messed up for us..i.e the sun would sorch us because there are no clouds to block it etc. I much rather would prefer humanity to focus on equal right and justice across the globe and eliminate wars and poverty. End of my 2 cents.

So your saying that by trying to get cleaner energy we'll actually make climate change worse? Why exactly are the clouds going to disappear?

Yes, we will definitely affect our lives negatively. I would agree that we have to curb our energy consumption but this should not be the prime objective in the world as there are plenty more pressing issue that need to be addressed. The clouds will disappear because we would be using anything that causes exhaust fumes etc. remember when Ujsdhfuighdcbrkauirbku errupted in Island and there were no planes flying for a while...did you notice how clear the sky was? Well, no imagine if cars wouldn't spit out exhaust fumes as well...we'd be pretty messed up in the long run.

Actually I think that focusing on *rights* and justice at the end we would unblock plenty of useful projects that nowadays are held back by vested interests, etc.
I don't see this Stanford study as promoting some kind of tree-huggable future. Rather it is, rather interestingly, an interesting business opportunity, possibly for millions of workers across the globe...

Clouds are primarily water vapour, the more water on the planet in liquid form, the higher the temperature, the more clouds. More clouds mean less heat during the day but less insulation at night. I don't know how or if it evens out.

Carbon into the atmosphere means smog which means extra insulation but less energy getting to the ground as well. The balance on this one seems to be more insulation than reducing heat.

In reality, we could go green in 10 years of less if we really wanted to. There is just not the pressure as the majority of the people are playing ostrich over the majority of the real issues.

Tough, billions will die. Nothing we can do about that. Find a country that does more about it than others and bed in for the long haul while our species sorts this problem out. I think it will most probably be done in about 90 years.

Pretty damn sure clouds existed before we came along and started making them with our cars.

I'm pretty sure we can have clouds AND renewable energy sources AND justice.

Actually improving renewables etc might promote justice etc as oil becomes less political.

I've already started plans, here's my evil mastermind plan

1 make a giant dish, send it into space to blot out the sun, then blackmail world for sunshine.

Next we must eliminate the competition:

2 Make machine to steal all the wind.
3 Take out the moon, prevent tidal power
4 Freeze the centre of the earth, stop geothermal

Have I missed any?
