Renewable Energy is not limited to choice, options, source, or vision.
In fact it drives a wider perspective known as Sustainability.
Simply explained, Sustainability requires an orchestrated style of living across the world to ensure the present activities of nations do not harm or deny global peace and the resources like energy, food, water and clean environment for present and future generations. All for a simple reason: resources on our planet are limited, and harsh practises be it war mongering or just reckless consumption will bounce back on all of us !
Part of Sustainability demands switching to Renewable Energy.
Renewable Energy sources are a matter of availability and technology. There are abundant options contrary to propaganda that Renewable Energy requires advanced technology.
Anywhere in the world, you either have lots of sun, lots of wind, lots of rain, ocean access or combinations of them. Choice is driven by economy.
There is abundant low tech Renewable Energy that can be tapped by utilising existing unused facilities everywhere.
As for advanced technology, Hydrogen will be the future path. Whether as substitute for petrol in cars, or as Fuel cells to generate electricity, or as Fusion. Water will be the source of Hydrogen.
There is however, a snag.
If Global Warming becomes irreversible, we might not have the opportunity to correct our deeds !

I vote for solar electric. It is not home yet, but Ovshinsky of Energy Conversion Devices has been working on the problem for years and some progress has been made. At present, a solar electric plant costs about $10 a watt, plus installation, and can generate about 25 cents worth of electricity per watt per year. Obviously, unless subsidized, that's a bad deal -- you'd be better off leaving your money in the bank. But if you're willing to stick it to the taxpayers, you can make out; a friend in California installed a solar electric plant about three years ago -- no battery, so it was cheaper. The sticker price was $13,000, but subsidies paid all but about $5,000 of this, and the thing generates about $300 worth of electricity a year. Not a great return, but it beats the bank.

It will have to be a number of different sources, hydro electricity, wind, solar, bio diesel.Water tide(Moon Powe) and wave power.
French have one tide power generation system.
I think Bio Diesel could be a clear winner for transport, manufactures could easily improve diesel engines to 120mpg+
Ethanol and Flex Fuel Cars LPG. All are less polluting than gasoline. Recycling of emmision gasses. Fuel Cells if they reduce cost.

I think Solar energy,wind energy and biofuels will rule the world one day...

solar would be the effective coz it is inexhaustable
where as wind ,thermal,hydro energies are exhaustable
