The main idea of this passage is that ----.
We are all involved in the oil business every time we
start our cars, turn on our lights, cook a meal or heat
our homes since we are relying on some form of fuel
to make it happen. Up to now, it has inevitably been a
fossil fuel, part of the carbon chain, and just as
inevitably, that will have to change. Long before we
decide to stop using fossil fuels, costs will have
already made the decision for us: not just the
monetary cost, but the human cost, the cultural cost
and the environmental cost. We will, quite rightly,
demand that our future energy be both sustainable
and renewable. We will expect a lot from the likes of
solar power, wind power, geothermal power and
hydrogen fuel cells, and it will take time.
