The war against renewable energy

Regardless of climate change, renewables are cheaper and more reliable than coal and gas and require less maintenance and running costs.
Battery technology is making the electric motor, which is massively more efficient than a petrol motor, more efficiency and giving it the run time required to surpass the petrol motor.
It’s mathematics.. the energy density of batteries is the key, power storage is the key, the advancements in battery technology in the last 2-3 years has been massive.
People talk about the climate change con, the real con is the lack of development of electric powered vehicles etc in the last 50-100 years…

Yes, and it'll never reach hydrocarbon level. Not flying a jet without kerosene

Green tech is yet another con to keep capitalism going. The only sustainable future is low tech and socialism, and we're going to do it the hard way it would appear

Thankfully China, with government controlled capitalism, is taking up the slack from the lack of development from countries that have been hijacked from the fossil fuel industries…

The one child policy was probably the most meaningful climate policy so far and the market reforms of Deng the most disastrous. Tale of two cities

"Airplanes will certainly go electric. Of course, the energy required to make planes fly is significantly higher than that of cars. It takes around 400 watt-hours per kilogram of battery for an airplane to easily fly 1,000 kilometers or more, including some reserves for emergency range." Elon Musk 2022…


China just hit 500 watt hours per kilogram…
Battery planes are already in production … it’s only a matter of time before regional planes are battery…

They’ll be safer than carbon Aircraft…
Let’s say a plane runs out of Battery at 30,000 feet. On decent they could charge the battery, and have power restored for the final flight stage.
Exciting times.

World’s biggest grids could be powered by renewables, with little or no storage – if we are smart enough

If the world learned to be smarter and more efficient, it could go fully renewable with little or no storage. But that’s not the way markets are designed.

Just googled. Snowy 2 will be 2.2 gw

Snowy 2 is $10b+ for almost no increase in net generation. Its shuffling checkers pieces so that we dont waste electricity in the middle of the night.

Its to be used as a battery.
Its way bigger than anyone is thinking with actual lithium batteries.

The idea is to pump water up using surplus solar ( which still needs to be built most days ) so we actually have power at night after the power companies walk away from their coal stations.

400km? Take your Tesla.

If you managed to fill 2 flights from Melbourne to Wodonga ( or Launceston ) and back every day for 10 years, you could pay for it by just charging $4000 one way. ( However if you had to pay for electricity, ( I doubt it will be free for big commercial users ), maintenance, and make a bit of profit. Those tickets might get a bit expensive.

Yes but its $10b+ for no net increase in energy.

Was originally $2b. Just looked and its now at $13b with at least 4 more years of blowouts to come.

Australian government contracts....not sure why you can quote ten bucks and charge 30.
Its still a good thing worth more than 13 billion of lithium ion.
Storage is worth more than "net increase".
Any dick can buy some solar panels and give a net increase around noon on a clear day.
 
The stupidity of the LNP and anti renewable halfwits when criticising the costs upgrading the grid … the same FWs that blocked the roll out of fibre to the premises….
9 years of no energy policy from the LNP has cost this nation billions in tech advancements.

Charging a ferry in 5 minutes with 100meg charging …

Where smart ferry charging begins with a smart grid

NORWAY: The Hareid-Sulesund ferry operations have reduced CO2 emissions by 7000 tonnes annually with the introduction of electric vessels. In transitioning ferries from diesel to pure electric power, powerful onshore support is essential, in the form of reliable infrastructure for rapid charging...

I'll bet my mothers life it wont happen.

The weight of a battery vs its energy density will never get there. You'll never get economical passenger aircraft using electric batteries. It's bloody thermodynamics

Just use sailing ships and take your time(not a joke, actually the answer to climate change)

The advancements in battery tech in the last 5 years has been nothing but extraordinary… from 175watt per kilo to now 500watt…
500watt has long been considered the break through aircraft needs to be to start being viable…
Are you saying we have reached the maximum ever?

DHL just order 5billion worth of small frieght aircraft…

It just shows how bad our media is reporting on these amazing advancements…. Keeping the idiots dumb.

Capitalism right

Call me when it happens at scale yeh, you're posturing shit that hasn't happened yet.

Yes, batteries are mature tech, there won't be a massive advance
