Low Cost Solar With Thin Film
Thin film solar ought to be a third of the cost of conventional PV panels and as low as 5 to 7 cents per Watt. 20 years in development and recently invested in by FFI from Fortescue Minerals Group.

Wind Turbines Kill Birds – Fact or Fiction
Wind turbines do kill birds but are not the bird shredders especailly of rare birds such as raptors (eagles, kites). Painting one of the blades black reduced raptor / eagle deaths by over 70%.
Feral cats remain the most lethal risk to birds.
China Renewable Energy Plan
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.
Stop Burning Rocks for Energy
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.
OffGrid Uninterruptible Electricity
Backup generators have been used for conventional grid supplied electricity and are now moving to include batteries and solar to ensure households and businesses can keep operating even in extended blackout conditions.
Ownership of Australias Electricity and Grid
An improved electricity distributon network will be needed to transport energy from renewable energy generators (solar and wind) to cities and factories. Who owns the existing network? What improvements are needed.
Evidence of Increasing Renewable Energy
Evidence of increasing renewable energy comes from most countries. Australia is one of the fastest changing but the USA is also rapidly changing, as is China
Germany’s Russian Gas Disaster
Germany made a decision to build a new gasline from Russia – the Nordstream 2 for 11 billion. They could have invested the same in wind power and now save themselves $200 million per day of cost.
Underwater Power Cable for Renewable Energy
High Voltage DC transmission systems are driving underwater power cable for renewable energy transmitted over thousands of km from Africa to UK or Australia to Singapore. Cheap solar is driving the change.
Carbon Footprint of Wind Turbines
The Carbon Footprint to build a wind turbine is paid back on average in 7 months, and costs about 10gCO2-equivalent compared to gas at 600, and coal at 1,000 g-CO2/kWh.
Recycling Solar Panels and Wind Turbines
Recycling solar panels and wind turbines is a common arguement against renewable energy yet the industry has been steadily getting to 100% renewable components at end of life.
Offshore Wind Technology Opportunity
Wind powered electricity has been developed onshore, but the drive to offshore wind has picked up for 3 reasons. Decreased costs, no land impact and better wind profile
Geothermal Energy Opportunities
Geothermal energy is used in many countries. Quaise is intending to use gyrotron powered drilling to drill deeper to harness higher temperatures and pressure and convert fossil fuel stations to geothermal.
Green Energy Saves $5400 per year
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
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.
Coal Mine Replacement
Coal mines continue to be constructed but face becoming stranded assets with the change to RW. But coal mines are half of the worlds mines and less than 17% of the revenue. Will other EV minerals replace them?
Simple Power by Freeing Energy
Freeing energy explores the energy in the world and shows how local free energy using PV panels and batteries will provide energy to 3 billion in energy poverty and disrupt 135 years of Big Grid.
Fossil Fuel Company Lies
The Angry Clean Energy Guy talks about corporate evil: comapanies knowingly doing harm. Exxon, BP moved responsibility from their fossil fuel CO2 emissions and pushed “personal carbon footprint”. He outlines Adarni as a worst case example.
Renewable Energy Transformation by 2025
Australia can and should get to 400 % renewable energy by 2030 to be a leader in carbon planning globally.
