Gas generates expensive electricity.

.

The Coalition say they will make more gas available, and this will cut electricity prices. Not true. A careful look at the South Australian wholesale 5-minute prices on the AEMO website shows that when renewable generators compete, the wholesale price of electricity drops, e.g. minus 24 $/MWh, and when this competition drops, gas generators set high prices like 300 $/MWh. Even with big cuts to gas prices, gas generators cannot match negative prices. Gas generates expensive electricity.

Coalition’s simplest stat is deceptive.

.

The Coalition is selling its nuclear scheme using fraudulent statistics. Their simplest statistic on electricity costs is deceptive. It’s a stark warning that we can’t trust their future nuclear costs and timings.

The Coalition’s nuclear folly

.

The Coalition claims nuclear power could start by 2036 (red), but given nuclear delays overseas, this is unlikely. Even with the 2036 start, nuclear will be too late to replace retiring coal (AEMO, black), forcing the Coalition to subsidize extended coal generation (brown). This scheme is also frighteningly enormous: 4.1 times the capacity of the vastly over-cost and delayed Hinckley Point C plant in the UK. See The Coalition’s nuclear folly.

The massive cost of importing fossil fuels.

.

Australia spends $ 61 billion a year buying fossil fuels from overseas.

We must electrify to reduce this money flowing overseas – and gain fuel security.

Australia can be a renewable energy superpower

.

Australia glows orange on this map, showing that we have outstanding wind and sun resources compared to most developed countries. And we have abundant minerals, like iron ore and lithium. So, Australia can act on climate and become a renewable energy superpower. Wins for our climate, industry, jobs, and prosperity. See Australia: A Renewable Energy Superpower

The critical danger: Heat amplifying feedback cycles

The hotter our planet gets, the hotter it will get.

Burning fossil fuels has set in motion planetary processes that are amplifying the current heating. For example, global warming is melting permafrost, which is releasing methane, which is increasing global heating.

More global heating		More melting of ice containing methane
More greenhouse gasses		More methane in the air

These vicious heating feedback cycles could end life as we know it, so we need urgent climate action.

The inefficiency of hydrogen.

Hydrogen is inefficient for many applications. For example, battery electric cars are more efficient than hydrogen cars; a car powered by green hydrogen uses about 2.3 times more renewable electricity than a car with a lithium-ion battery. We need to be wary of the current excitement about hydrogen.

Site Purpose

I have urged climate action on this website since 2009.

I also present “amplifying feedback” as a process that can help us understand climate change and human problems like addictions. Amplifying feedback cycles are driving change all around us, and this led to my website’s name, “Feedback Reigns”.
