Renewable energy discussion
China has invested heavily in coal for electricity over the past 30 years but has made the switch to renewable energy and targets all new energy from renewable sources by 2025 and net zero by 2060.

We have burnt rocks for a million years and every year we burn 500 years of the products of the carbonaceas period as fossil fuel. Renewable energy is not fuel. It harnesses energy from the nuclear sun. Batteries can store it. RE stops energy poverty.

Green energy saves $5000 per year and Australia can do the Big Switch from fossil fuels to renewable energy with rooftop solar and batteries. Change is an increase wealth to households, not a cost.

Recycling effectiveness is poor because companies have passed the responsibility and cost of recycle / reuse onto consumers. Less than 7% of all plastic is recycled. Almost as much is dumped at sea. Time to change.
