World energy consumption 1970 to 2005

Free energy from the sun for the next 2 billion years

Maybe we can find a way to tap dark energy, which seems to have an almost endless supply.

[pegobuilders]

vast savings on your energy bill and a dramatic reduction in energy consumption can be achieved by improving insulation

[ukiki2012]

I always look at these numbers on these youtube videos and I'm thinking there are 30,000,000 people watching the damn fall out boys or 100,000,000 computer screens and towers running to watch a guy dance around like a retard, it's so wasteful and yet it shows how much energy is being used, it's really belittleing...

Natural gas doesn't count as a fossil fuel if it is derived from sewage and agri animal manures, then it's renewable. It is do-able.

See cow power, Vermont, here on the tube.

Also on net, biogas in rural China, Paul Henderson, CityFarmer website.

Also georgiastrait dot org/?q=node/359, Salter on amazing stuff in Sweden.

That is true and in some cases that also can reduce global warming gasses because methane is more potent than CO2. However the supply of this is not nearly enough to meet world demand

[margot980]

Yeah, CH4 is 15x more potent, so a good gain. As for the world supply, some is much better than none, and our current sewage disposal and treatment seem perhaps more shame-driven than rational.

While the data on energy consumption in this video is instructive, it is wrong to accept that energy consumption must continue to increase, and therefore we must add to energy resources. The most effective "alternative" is not nuclear or even renewables: it is improved efficiency.

[demexii1]

That is wrong, as efficiency increases so does demand (as it is now cheaper to use). It is Jevons Paradox. We either need to use less or get different fuels. I like the latter personally.
