Yes and they use fossil fuels to make their cars and solar panels. There is a point at which "green" becomes ridiculous.
But then we would be complaining how GM can't make enough Bolts because they don't have the battery manufacturing capacity. The Giga factory has its issues but its intent is to meet the future and the demand.Marry Barra wishes she had a 500,000 order backlog for the Bolt. Those who think big have big problems. The rest of us just ridicule from the sidelines.
Trollin but then add the winky to make it alright.. nice.
You bet. And probably the best way to do that is with nuclear energy. Solar panels at one time barely made more energy in twenty years than the energy it took to make them. Haven't looked into that in awhile to see if that has improved. Maybe the thin films? Problem there's no industrial scale hydrogen made by electrolysis that I know of and is very energy intensive (there's some interesting catalyst work going on to improve this). One issue is the process doesn't produce pure hydrogen and removing other species is problematic.
Yeah, but why do that when it's much cheaper and faster to derive it from hydrocarbons?
Let's get you up to date:Solar panels at one time barely made more energy in twenty years than the energy it took to make them. Haven't looked into that in awhile to see if that has improved.
How many years of operation does it take for a solar panel to generate as much energy as was used in its manufacture? (AKA: Energy Debt) The National Renewable Energy Laboratory and The Journal of Environmental Science & Technology found that depending on the technology used, it takes between one and four years for solar panels to earn out on their energy debt. Consider that most panels are projected to last between 20 and 25 years with proper maintenance and normal use, and you can see that there's a net energy gain here that's rather significant.
Yes but hydrogen made this way is the most expensive way to make hydrogen. It takes more energy in than the hydrogen energy density produced. It takes a 100% efficeint electrolyser 39.4 kwh to produce 1kg of hydrogen gas from water which contains 33 kwh of energy density. Notwithstanding the energy needed to compress the hydrogen.
