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?
..ehm, yeah close shops on Sundays...wait, we already got that one.

Biofeul and biomass.

But I suspect that stopping the sun would be enough in any case.

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.
Actually the fight for oil is a major cause of wars and poverty and injustice. If more countries were self sufficient or even just a bit less dependent on the mighty few I think there would be more of a balance of power in the world. Also, as far as poverty and famine go - growing food has a huge 'oil' demand - putting up costs. So less of a demand on oil for food production would also help poverty. There was a great show on BBC a few years back called 'The Future of Food' presented by George Aligiah. If you search on youtube you can watch it (need to watch it in small bits). I'm also doing an Open Uni course called 'Why people need plants' which discusses biofuels. Very basic level but enlightening and motivating.

Also with regard to the sun scorching us due to lack of clouds. Well I wasn't there personally but I believe during the 'iceage' there wasn't any pollution and instead of being scorched the earth froze!!!

Nah -there will be plenty of biomass rotting away on the planet. Eventually will become petroleum again.
But...
Wouldn't it be ironic if the next specie that will inhabit this planet, in a few million years, jumped straight ahead to develop clean energy bypassing all that new carbon-based juice alltogether? we would have exinguished ourselves for nothing

Hmmph!

3 Take out the moon, prevent tidal power
I feel the treehuggers should think about the consequences of their actions. Tidal power is an excellent example.
If we take tidal power it means (based on conservation of energy) that the moon will slow down it's rotation.
If the moon slows down enough there will be no more centrifugal force -> moon is going to crashland into earth

I'll take global warming anyday !

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.
I'm sure that if enough effort is put into it a viable storage medium can be found. Every source of energy has its advntages and disadvantages and it would be wrong to discard any at such an early point because of one snag that can be fixed.

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

People dont worry about the world the world will survive whatever we do to it.

I would start worrying if mankind would survive.

As we saw in the last Tsunami the earth under the ocean decided to stretch its little toe and created a good size earthquake followed by a tidal wave.

Renewable energy is in the long term cheaper so all those who think tree huggers are behind this technology think again! Its the corporate guys behind it and they see a huge profit and savings to make more profit. Especially with these huge subsidaries being given.

If this wasnt so, the initial statement in this thread would not be true.

What if they use wikileaks and revolts in Africa as media tools to distract you from climate change?

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

The article says "Ninety percent of the production would come from windmills and solar energy plants"

Windless nights will be pretty cold?

As people have already said the storage of power is still an open point.

Also I do not believe the solar panel technology has yet reached the point where it can deliver power for prices that are anywhere near to current mass power production prices. So this is a recipe to double power prices which would be interesting for large companies, no?

The issue with bio fuels is that to grow them they have to use land that is or could be used for growing food crops which means higher food prices (less land for growing food = less food = higher prices) & in turn many more poor people will starve.

Myself I support the concept of renewable energy sources but I do not believe we yet have good enough practical solutions.

Quite correct except for your use of the word solution. The problem here is that there is not enough political, social or ethical drive to create practical implementations. We have the theory, we can prove that the solutions will work, but until we take it seriously that the implementation of them is a good idea, we are not going to iron out the practical problems.

That is why the Wright brothers get a certain amount of credit for human flight. They did not invent it, they did not come up with the theory or all of the science, they were the first to put their balls on the line and practically implement it. They had a solution that they practically demonstrated.

Really do not agree; there are many companies building solar panels & windmills & working on improving the technologies. Take a walk around & you will see them everywhere.

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

The truth is that all "renewable" energy requires subsidies to make them economically viable. Wind only works in certain places. Water, the most common of the renewable energy systems in use here in Switzerland, requires large amounts of water and high mountains, not very useful in deserts. Solar only works during the day, and as it has been stated earlier, storing electricity is VERY difficult at the moment. As to climate change, since the best weather reports are never more than 1 week out, how is it that these people claim that they can predict the weather 10 to 20 years out? And why is it that there has been no rise in temperature for the last 15 years? Climate change is a way for the various governments around the world to make us feel good about paying higher taxes. If it's "for the good of the environment/planet/nature whatever, nobody minds to pay more money for it.

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

Fossil fuels won't be out of the energy mix for the next 75 years at least. At the moment, the market is moving towards natural gas as a stop-gap fuel for when wind and and solar power plants aren't providing power. It's the cleanest fossil fuel available and the infrastructure is there, with more pipelines and LNG plants being built every year. You can also store it, which you can't do with renewable for the moment. You'll also see more nuclear power plants once people get over tree-hugger propaganda and realize that nuclear waste isn't some neo-green sludge that kills everything within 100km of it and that it's a plentiful and non-polluting power source when done right (see France).

Wind energy has become very effective in some places. On certain days during the year, it provides over 70% of Spain's energy, for example.

All these things are temporary. technology is progressing and new things are being developed all the time.

There is one anecdote that when the motor car was invented that one pundit predicted the invention would never catch on because (he said) where would you take all the men with the red flags from who have to march down the street in front of the cars? Naysayers are often wrong because they think too much within the paradigm of their own time and cannot see that conditions may change.

There are already several different solutions in the pipeline to cover for wind power when the wind stops blowing.

CSP plants make solar energy that is not just available during the day but continues to flow throughout the night because the conversion is not direct but through the intermediate of steam which can be stored for tens of hours.

As for subsidies, yes, renwable energy does require subsidies, just as conventional forms of energy do. Fortunately, in contrast to oil subsidies, those subsidies are not payed in the price of soldiers killed in Iraq and Afghanistan.

Yes, yes, I mean as a global solution that will replace the bulk of fossil fuels within the next 10 to 20 years, and that really does mean global, not like Europe, like the U.S.A., China and Africa and everywhere else as well.
I know we are putting major amounts of work into the finding those solutions, it is just that they are not pervasive yet. Some of the work that they are doing in wind and solar is truly impressive though.
