In the long run, everyone is dead.
No, for other people it looks a lot like you think that discussing climate change means panic. It does not.
Well, you are saying that everybody is gonna die cos the global warming thingy. Some retired generals are predicting millions of displaced people, wars and famine. Is not something to panic about?
Well, for one, batteries. By Centralizing electricity production, and then distributing out over existing grids, and in batteries for cars and such, it becomes much easier to improve efficiency and/or scrub your stack output.
Umpf... Batteries are not a primary source of energy, You need energy to charge the batteries. And they are expensive, environmentally dangerous and inefficient, they lose energy over time if the battery is not used. And good luck with running a truck powered by batteries.
One of my professors (and for you Urederra, his degree was in economics, not panicking) ran some basic calculations, and showed that by doing this, the US could reduce carbon output by about 60% over the next 20-30 years, in exchange for an increase of price of 2-6c/kWh. Thats low enough that you wouldn't even notice it next to inflation.
Economics was the science of the wrong predictions of the 19th century. (Malthus and company) Climatology is the science of the wrong prediction of the 21st century.
Moreover, if you centralize energy production and then you distribute the energy produced, you are going to lose power transporting energy. Decentralizing energy production yields better results, both economically and environmentally since less energy is wasted in the transportation.
Then, somewhere down the line, we can look at changing over our power plants to Nuclear Power if feasible, various renewable alternatives, or if we get really lucky, Fusion Power.
Nuclear power and solar/wind power are OK, but there is no way you can run a car efectively with nuclear, solar or wind power. But hey, if you know how to, then go ahead. Nobody is stopping you.
And if it is so easy and economically feasible that everybody is going to change because the change is not traumatic at all then Why some retired generals are warning about possible world conflicts due to the predicted effects of global warming?
