Bryan Leyland: Storage - the Achilles heel of wind and solar power

The Government’s “Net Zero New Zealand by 2050” ambition foresees 12,000 MW of new wind and solar power – 1.5 times the entire existing installed generating capacity – to meet the 50% increase in energy and peak demand expected from electrifying transport and heating. The disproportionate increase in installed capacity results from the low average output of wind and solar farms. Installing this much new capacity is a major challenge in terms of technology, cost and resources. According to Professor Kelly, an eminent New Zealand engineer now residing in the UK, it will cost more than $500 billion.

Stuart Smith: Affordable Energy, Food vs Climate Change Policies

World leaders are meeting at the latest UN climate conference COP27 in Sharm El Sheikh, Egypt.
