This is a wonderful chart from 1bog.org (One block Off the Grid)

 

Really have you ever thought about how much land you would need to meet all your family’s calorie needs for a year. This is a great chart.

 

1bog.org is an inventive group that can help you find the most cost-effective way to have solar power. One Block Off the Grid makes it easier and more affordable for homeowners to go solar by organizing group discounts, vetting solar installers, and providing you with objective information and advice along the way. Our solar advisors don’t work on commission. Their salary is the same whether you end up going solar or not, so the information you receive from One Block Off the Grid is always 100 percent unbiased.
