Welcome to today’s episode, where we break down the real cost of powering our world. We’re not just talking dollars—we’re talking environmental impact, lifespan, and long-term value. Let’s get into it.

Solar Power

• Cost: ~$32.78 per MWh

• Example: In Australia, rooftop solar has driven wholesale prices down by 71% in just one year.

• Pros: Low operating cost, scalable, great for sunny regions.

• Cons: Intermittent, needs storage or backup.

Wind Power (Onshore)

• Cost: ~$36.93 per MWh

• Example: The Coopers Gap Wind Farm in Queensland powers over 260,000 homes.

• Pros: Clean, efficient, low land footprint.

• Cons: Variable output, visual/noise concerns.

Hydropower

• Cost: ~$55.26 per MWh

• Example: Snowy Hydro in Australia has been running for decades and is key to grid stability.

• Pros: Reliable, long lifespan, great for base load.

• Cons: High upfront cost, ecological disruption.

Geothermal

• Cost: ~$36.40 per MWh

• Example: Iceland runs almost entirely on geothermal and hydro.

• Pros: Constant output, low emissions.

• Cons: Location-limited, high drilling costs.

Biomass

• Cost: ~$89.21 per MWh

• Example: Some sugar mills in Queensland use bagasse (sugarcane waste) to generate power.

• Pros: Uses waste, dispatchable.

• Cons: Emissions, land use, not always carbon-neutral.

Fossil Fuels (for comparison)

• Coal: ~$72.78 per MWh

• Natural Gas: Varies, but often higher than renewables.

• Cons: Ongoing fuel costs, emissions, health impacts.
