I’d rather people went rooftop solar, and put that land to producing food. | ||||||||||||||||||||

The consumer rooftop solar cost is usually one of the most expensive ways you can generate electricity - often several times the cost of utility solar installations. The high rooftop solar price is usually hidden (at least in the USA) because no power source has been as subsidized as rooftop solar. Besides direct subsidies, wealthier home owners have often been paid the retail rate for the electricity they sell to the grid. This causes higher electricity bills for those in apartments and those who can't afford to put panels on their roof. Also, in almost all cases, the home installation doesn’t have enough battery power to actually last through inclement weather and so is free riding on the reliability provided by the grid, putting more costs on the less well off. The whole thing is sort of a reverse Robin Hood scheme. Rooftop solar is good but it shouldn't be a gift to the wealthier residents paid for by those less wealthy. Any subsidies for solar power should go to utility grade solar. Money is limited and is fungible - a dollar spent subsidizing utility solar will go much, much, further than a dollar spent subsidizing wealthy homeowners who install panels on their roof. | ||||||||||||||||||||

That land is producing food for cars. If we covered half in solar panels we’d have almost enough energy to power the country. Turn the other half over to food production and you’d come out ahead on both energy and food. | ||||||||||||||||||||

Why do you assume that solar and production of food is mutually exclusive on that land? Agrovoltaics is a thing and can often have benefits to the growing of crops. | ||||||||||||||||||||

It's a common mistake to believe there isn't enough land to grow food, and that is simply false. We throw tons and tons of food away every year due to spoilage and other factors. Even in many parts of Africa scarcity of food is caused by waste and distribution problem than simply lack of arable land. And when you think about the millions of lands used to grow bioethanol I think we can safely convert that for solar installation without worries.Agrovoltaic is also a practical approach for a lot of crops and farmers so that we can grow and produce electricity side by side. | ||||||||||||||||||||

We already produce enough food. Rooftop solar by definition is an inefficient use of resources. | ||||||||||||||||||||

Do you know how much land there is that is simply not worth farming on? There are deserts everywhere. | ||||||||||||||||||||

A roof is quite literally the worst place to put solar panels. Its a load most roofs are not designed for, and the whole point of a roof is to keep water out, which is compromised by attaching stuff to it. The most efficient way to do large scale solar is with semi-local utility scale arrays with ultra efficient inverters and enormous chemical or hydro storage. We have a lot of unused land, that's not a problem | ||||||||||||||||||||
