Mining professor Simon Michaux has done a mammoth study on electrifying the global transport sector. He worked out how many cars, trucks, ships there were and how far they travel.

Renewables – can we ever get there – when energy and climate clash

Hydrolakes in Aotearoa/New Zealand have had many years of low rainfall, but it is now happening more frequently. In dry years we revert to coal generation, making the transition to renewables harder.

When New Zealand hydroelectric power stations ran low last summer, we beefed up electricity generation with another coal fired unit in Huntly. Environmentalists were shocked. How was New Zealand going to meet its climate targets now?

As Naomi Klein said “The economy is at war with the climate”. We are going to need all our collective intelligence to downshift without chaos. Can we manage an energy descent without it being haphazard and dangerous socially? Continue reading “Sustainability and Money”
