I know this is a science forum and not a forum for conspiracy theorists but I have always been intrigued by the idea of a world where everyone has access to 'free' energy. What impact would it have on the world? Would it solve 99 per cent of all problems?
There will never be "free" energy. You'll always pay a fee to the power company to maintain the plants and transmissions lines, regardless of what the power itself costs to create.
I think the term you might be looking for is "unlimited" energy?
There's no such thing as unlimited energy either.
I think he is looking for a way to get renewable clean energy.
There is a lot of energy around us, of course the sun provides a lot of energy. The wind and the tides as well, the earth also has a strong electromagnetic field and you can also use gravity (waterfalls for example) or geothermal energy.
There's also a lot of energy (in the form of radiation) basiacally bombarding earth from all directions, there's probably a way to harvest that energy as well, Altough it might me more effective to let a satellite do it, because the atmosphere of earth filters a lot of it out.
Energy can't be produced out of nothing, but luckily we don't have to, you just have to know where to look.
