Yes I think we all got that it was sarcastic. What was stupid was that your sarcasm was seemingly intended to ridicule the practicality of non-fossil fuel energy sources. Casting doubt on the viability of these has been one of your themes ever since you showed up here. A number of us have tried to set you straight about that, but it seems to be an uphill struggle.
On your battery question, yes battery storage is already done commercially and I have already commented on further battery developments. Other forms of storage of intermittent energy production include hydroelectric (pumped) storage and thermal storage - a sort of battery for storing heat, using the latent heat released when a substance changes phase. Here is one example I found at random on the internet:https://sunamp.com/en-gb/wp-content/uploads/sites/2/2024/02/Thermino-Brochure-Digital-Artwork_Low_Res_aad-uk-th-br-v1.pdf
On your question about how we should ideally move forward, I agree with others here that a "master plan" in detail may not be a sensible approach, partly due to the vicissitudes of politics and partly because the pace and direction of invention and commercialisation, in a free-market economy, is such that any plan would be quite likely to be overtaken by developments that were not foreseen when it was devised. However the elements that a government should pursue, as vigorously as public opinion will permit, must obviously include both incentives and support for more efficient use of energy (public transport, insulation, fuel economy, waste heat re-use) and incentives and support for moving away from fossil fuel based energy. The forms those incentives take, or should take, in practice vary from country to country.
I'll give you one example. One absurdity in the UK is that electricity bills include a surcharge to help fund the development of the network to accommodate the shift to renewables. However gas bills do not, as gas uses a legacy network that is not being developed. It should be the other way round, so that legacy fossil fuel use funds the shift to renewables. That would make gas more expensive and electricity cheaper which would also be an incentive to shift over. But politically this is dynamite, as most people heat their houses with gas and for poor people, increasing their gas bills too much could make them unable to afford to heat them in winter, given that these people are the least able to invest in a new, electricity based, heating system. So this kind of thing has to be handled, politically, with kid gloves, even though the science is obvious.
