I have been writing about this for years and I lived off grid for 30 years.
Solar and wind energy capturing devices as well as nuclear are not alternative energy sources. They are extensions of the fossil fuel supply system. There is an illusion of looking at the trees and not the forest in the “Renewable” energy world. Not seeing the systems, machineries, fossil fuel uses and environmental degradation that create the devices to capture the sun, wind and biofuels allows myopia and false claims of renewable, clean, green and sustainable.
There is a massive infrastructure of mining, processing, manufacturing, fabricating, installation, transportation and the associated environmental assaults. Each of these processes and machines may only add a miniscule amount of energy to the final component of solar or wind devices yet the devices cannot arise without them. There would be no devices with out this infrastructure.
A story in pictures and diagrams:
From Machines making machines making machines
An oak tree is renewable. A horse is renewable. They reproduce themselves. The human-made equipment used to capture solar energy or wind energy is not renewable. There is considerable fossil fuel energy embedded in this equipment. The many components used in devices to capture solar energy, wind energy, tidal energy and biomass energy – aluminum, glass, copper, rare metals, petroleum in many forms to name a few – are fossil fuel dependent.
Wind used by sailing ships and old style “dutch” wind machines is renewable and sustainable.

Here are pictures of how we reconditioned the old house.
Below is the house at the orchard. The part you see was built in the 1940s. The inside was worse than the outside. We replaced the floor with insulation below the concrete. We tore out all the plasterboard and insulation, added two by twos so we could have six inches of insulation on the walls and ceilings down stairs. We did the same upstairs.
So far the windows and the thermal mass of the floor keeps the house at least 30 degrees above the outside temperature during sunny days. We built insulated panels for the window to be inserted at night to preserve the solar gain. The cost was below $3000.
