Wind turbines, solar panels, home battery storage - if it's discussion about renewable energy you're after, you'll find it here.
No one talks about storage costs, heres my estimate:
Solar will provide cheaper power. Sun is free, no transport costs.Solar PV farm can be mostly automated. Build next to grid power.
Solar panels with 25 year life could be replaced after 2040 when costsshould half. Compare with coal each day buy, transport and burn coal.
Clean coal 1GW plant cost $4 billion.*Solar PV farm 1GW $1.6 billion.**Powerwall2 lithium batteries 1GW $0.9 billionSolar + Storage $2.5 billion = baseload power
In case of blackout in the day, storage can be used.
Coal has confirmed solar is cheaper and now wants taxpayer money.
Solid-state battery by 2025, long life lightweight more capacityTwice density, fifth cost of lithium.
* India 2GW Solar PV $3.2 billion** Powerwall2 14kW $11,000
