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?
