This post is not the popular song by the Beatles (😎), but it is the recently published book by Bill McKibben. The author presents the world's transition in electric power and heat from coal, oil, and gas to solar and wind power. The statistics he shares are so impressive.
Here is a link to a brief YouTube video to capture your interest in reading his book. The statistics he presents are so impressive and a wake-up call on energy production and use. I lean towards the solar panels as I have 12 on my house. The savings alone are amazing.
