How Many Light Bulbs? - From Cambridge Ideas

I'm confused I thought my electricity consumption was high, according to my figures I only use 24 x 40w bulbs per day not 125 as in video.
Is this exageration on purpose to make a point like so many Climate scientists today or is this guy just bad at maths or am I wrong?

Calcs energy consumption is about 24kw / day 1kw costs about 12p so total annual cost 24 x 12 x 365 = £1,051.20 if this guy's calculations are correct everybody else must be paying about £5,000/year for their electricity!

that's a seriously helpful, informative, thought-provoking video. Thanks very much.

Anti-nuclear ! Detest leaving the waste behind or living with risk of accident. Holitistic approach required eg. reduce usage, invest in new technology and research - apparently a new efficient system of gasification (of coal) has been developed. The physicist exhibited a narrow way of thinking - which is a bit surprising. Look at cost we pay for oil dependency both political and in human lives. Don't waste money on nuclear power stations - spend on new tech and dependency reduction instead.

I would like to see more discussion about insulation. Clearly, we use a lot of energy for heat or for air conditioning. A very well insulated house can reduce heat expenditure by 2/3rds. Straw bale, or the newer soy foam spray on insulation. New houses should be built with 4 or 5 times the current typical R value, sealing all the cracks. The future will be called The Age of Insulation.

I would agree. I am just stating more people don't go to solar because of these rediculous costs. There are far more efficient processes for generating useful energy, but it is the oil companies who have bought up all the patent rights to the said designs. One thing you might want to check out is "the Venus Project" google will lead ya to it. You're right about capitalism - we are slaves to the Rothchilds and Rockefellers.

There's enough lithium reserve base for billions of cars.

Conventional lithium batteries have piss poor energy density compared to what is theoretically possible. If you can make rechargable metal-air batteries(there's a quite promising ionic liquids approach being developed) you can beat the energy density of conventional lithium iron phosphate by a factor of ten with plain old zink.

The toaster might consume a few microwatts or something with it's handle up, who cares?

He has got numbers wrong!
One modern, 2.3MW wind turbine will provide enough power to run 1000 homes, not 200 people.

nuclear waste stays active over decades? DECADES??? CENTURIES!!!!! If not longer.

what would that do to the rivers eco system? I'd like to see numbers on that one. IF it doesn't make a 'dent' then that could be a good idea, yes. I'm afraid it won't be enough, though, rivers don't stream rapid enough, that's why they make dams and stuff
