Now I know why Mr. Softy owns so much farm land…

New research from Princeton University and Bloomberg confirms that renewables require 300 - 400 times more land than natural gas and nuclear plants

The answer is yes and no. It could be somewhat offset if homeowners would let solar cells be installed on their roof tops. Also, the calculation is likely based on legacy solar cell technologies with low optical to electric efficiency. I am not against renewables but I will read anything with a grain of salt.

The vast majority of house roofs are not well suited to solar because they are not at the optimal angle (latitude angle from horizontal), not at the optimal azimuth (South), and shaded. This does not stop anyone from installing them on roofs of homes.

A more suitable location is roofs of large stores and warehouses, where there is no shade, and they can be oriented optimally, and where a large need for electricity is located immediately below.

Another benefit of locating them on commercial buildings is that they offset purchase of electricity at higher (commercial) prices.

As warehouse roofs are generally not utilized for anything else, the panels arguably occupy zero space, which the study authors presumably thought of.

The reason so many panels are installed on house is politics - taxpayers paying for someone’s social statement. In New York City the subsidies have advanced the industry to where they are routinely installed flat or vertical, in the shade, or facing North (Columbus Ave & 100st, for example). I have never met anyone who likes solar panels enough to pay for them with their own money.

Whenever I see wind turbines the land under them is being used for farming or grazing or etc. Saying they use a lot of land is like saying planes use up all the land they fly over.

HG's comments are, as always, wonderfully exact.  Our new roof that will go up this week will not have solar panels because no one in NC is willing to pay us for the waste of money; in California they were happy to.
