Definitely worth the watch.
here are my cliff notes:
> human energy consumption, by means of burning fossil fuels, is the reason for green house gases, that in turn trap more heat, then our environment can sustain.
> technology to reduce CO2 emission, assuming the same level of electricity consumption -- is far from being available.
They had talked about Nuclear, sun, geo, nuclear fusion.
>more efficient means to convert to electricity:
>35% of coal energy is transformed to electricity
> incandescent light bulb converts only 5% to light
If larger city (NY, Moscow, Bombay etc) switch to better light bulb, 1 million ton of C02 emissions every year, each.
> simply changing from coal to gas cuts carbon emission by 40%
>half of worlds oil is used by 500mln road vehicles. 400 mln of those are private cars. each producing 4 times its weight in CO2, each year. Internal com engine is only 20% efficient. Cars can improve by 3 times (not clear, if they assumed electric only or not).
> when gas is not available option, coal can be gasified
>
>Taxation can work both ways, already there is a talk of carbon tax. But how to achieve compliance across national borders.
>Global warming calls for global response. but world is not a common market.
Examples they used is Easter Europe, other developing regions.
>How could this countries advance, but leap-frog energy developments?
Future must be different, developing countries cannot take the same path as the developed countries in the past.
