Sometimes wind and solar power produce more electricity than the local grid can handle. Better energy storage and transmission could move extra energy to where it’s needed instead of shutting it off.
Natural gas may still be cheaper than electricity in some cases, but the price of gas is likely to rise if New Zealand follows the Climate Change Commission’s advice to shift to electrification.
Green hydrogen produced using New Zealand’s mostly renewable electricity sounds like a great idea, but a high-tech smart rail and urban tram network is a more obvious and sustainable option.
Investment in renewable electricity needs bipartisan political support and some bold decisions if New Zealand is to meet its future energy commitments.
Emissions from road transport in New Zealand have doubled since 1990, and the Climate Change Commission recommends sweeping changes to switch to electric transport options.
