Making them big enough to supply the whole grid on their own would be a different problem., but it isn\'t one we need to solve.
The green hydrogen enthusiasts figure that we can store big enough volumes of liquid hydrogen to do that job, but that does throw away 75% of the energy used to create the liquid hydrogen. Batteries and pumped storage only throw away about 15%.

If the greenies had persuaded them to over-invest in cheap renewable generation, they wouldn\'t need to charge high volume consumers more for consuming more power, so presumably they haven\'t. In fact it takes time and money to buy and install new generating plant, and while the old fossil-carbon fueled year is still working it makes sense to squeeze it for some last dregs of output, particularly when the sun isn\'t shining and the wind isn\'t blowing. If they hadn\'t invested much - so far - in pumped storage and grid-scale batteries, they wouldn\'t have a lot of choice.
The greenies have been less vocal about pumped storage and grid batteries, which is bit silly, but the argument for that investment is less obvious, and people like Gnatguy can\'t understand it at all.
Hey Bill, \"renewables\" are also known as UNRELIABLES - they can\'t be depended upon (just ask the Brits).
They aren\'t. They are intermittent sources but the sun rises pretty reliably every day. You do need grid storage to bridge the gaps, and we haven\'t got enough of that yet. We do know that your failing mind can\'t grasp this idea, and there\'s no need for you to remind us that your senile dementia is getting worse.
Intermittent = UNRELIABLE.
So plants can\'t be relied to grow and feed us? Grow up.
HA HA HA HA!!! Hey Bozo, are you FUCKING SERIOUS??? Since when do PLANTS provide any power?????
Every time you stand up you do it by expending power derived from eating plants - either directly, when you yourself ate the plants involved - or indirectly when you have eaten animals that were fed by plants. Even the fossil carbon you are so enthusiastic about burning for fuel started off as plants, a very long time ago.
Neither sunlight or wind is predictable. Just look at the short term variation of both.
But the long term variation - which is what matters - is a lot smaller. You have to scale your storage to match the expected - and largely predictable - variation, but that\'s something you can design for, if you have enough sense to comprehend what\'s going on, which you clearly don\'t. You are far gone in dementia.
Hey Bozo, LONG TERM we are all DEAD!!!!!!! We need resources BEFORE THEN!!!!!!!!!!!!!!!!!!!!!
The sun comes up every day. We could hope that you would be dead before then, but we are unlikely to be quite that lucky.
Grid storage is aimed at bridging relatively short intervals - from one day to the next - or over a couple of days of bad weather at most. If you had a working brain you\'d adjust your rhetoric to reflect that obvious reality, but instead you recycle a line that may have worked for John Maynard Keynes, but doesn\'t work in this context.
Hey Bill, forget about storage for days, they can\'t even store energy for HOURS! Show me ANY utility level battery system that can store energy for days.
They all do. Pumped hydroelectric storage can store energy for years. The Hornsdale grid scale battery in South Australia is build with electric car batteries off Tesla\'s production line. Electric cars lose about 2% of 3% of their stored charge per month. Vanadium flow cells should do even better.
