Ken fished out another faded photo. “Wow, here’s Grandma Frieda Bea-Greener pointing at the solar thermal panels perched on her roof 30-some years ago. Those panels did reduce her hot water bill, but the maintenance was a bit much so they eventually came down. It was kinda like Uncle Will’s experiment with a small wind turbine on the farm. A good try, but…
“Ha! Here’s a shot of Uncle Les showing off his new rooftop photo-voltaic (PV) solar system. That would have been around 2012 because that year the cost per watt for solar had dropped almost 50% from the previous year, so he jumped onto the ‘solar express’.
“Ya know, in some ways, the clean energy revolution has been like learning to ride a bike. A few ‘scraped knees’ early on, but now that PV is SO economical, there ain’t no goin’ back. Just think, in 2011 the world price per solar watt was $2.00. The very next year it dropped to $1.08. By 2024 it was down to $0.26 - the least expensive source of energy on the planet!”
Ima knew that Ken Bea-Greener could get a bit over-excited about clean energy stuff. (With a last name like his, who wouldn’t be?) She’d read that currently there’s scant federal support for clean energy. So being a bit skeptical, Ima did a little research of her own. She learned:
- In 2025, renewables overtook coal in electricity generation.
- Solar costs less than half what analysts in 2015 predicted it would in 2025.
- Electric vehicle (EV) sales already make up a quarter of the world’s market (mostly China and Europe) – a threshold initially forecast for 2030.
“By golly, Ken’s right! With or without federal encouragement, a whole new world of clean energy is rapidly rolling ahead. Thank goodness, because this is our only home. We’re all forever… Earthbound.”
