Bill McKibben: “Texas is now installing renewable energy and batteries faster than California; in a single week in March, it set records for solar and wind production as well as for battery discharge.”
Solar Economies
Bill McKibben: “Whole economies are now relying on solar. California was powered by 100% clean energy for more than 100 days this year, and solar was the biggest source of energy in the EU last month.”
Solar Power: Fastest Transition in History
“People are now putting up a gigawatt’s worth of solar panels, the rough equivalent of the power generated by one coal-fired plant, every fifteen hours. Solar power is now growing faster than any power source in history, and it is closely followed by wind power.”
Bill McKibben
Three Terawatts of Solar Power
“It took from the invention of the photovoltaic solar cell, in 1954, until 2022 for the world to install a terawatt of solar power; the second terawatt came just two years later, and the third will arrive either later this year or early next.”

Nobody can hoard sunshine!
“No one hoards energy from the sun and wind; billionaires and fossil fuels executives can’t hold it in ‘reserves.’ It’s energy for everywhere and everyone.”
Rev. Lennox Yearwood Jr., President & CEO of the Hip Hop Caucus
Stand with our Kids and Grandkids
“It’s time for all of us who know that windmills don’t cause cancer and that not all energy comes from deep underground, to stand together with our kids and grandkids on Sun Day to stop the mind-numbing rhetoric and jumpstart our clean energy transition.”
Former EPA administrator Gina McCarthy
Common Sense Energy
Bill McKibben: “[At] some point in the last five years or so, we crossed an invisible line where it became cheaper to generate power from the sun and the wind than it did from setting coal and gas and oil on fire. We now live on a planet where the cheapest way to produce energy is to point a sheet of glass at the sun. This isn’t ‘alternative energy’ anymore–it’s the common sense obvious path.”
Our Unbroken Companion
“From the moment Earth first coalesced out of cosmic dust 4.5 billion years ago, one star has been our unbroken companion: the Sun. It has bathed our world in warmth, painted skies with dawns and sunsets, and sustained every breath we take. Every tree, every ocean wave, every heartbeat is a gift of solar energy streaming across 150 million kilometers of space to nourish life.”

Can we get it right?
“We really could get it right — we have the clean energy technology we need, and what we need now is the human energy to make it happen despite the obstruction of Big Oil. That’s what Sun Day is about, harnessing photons to power our lives.”
Ayana Johnson, Marine Biologist
Every Hour!
“The history is clear: scientists discovered things, fossil fuel companies lied, and the world heated up. But on a planet that receives more power from the sun in a single hour than the whole of humanity collectively consumes in a year, fossil fuels are not inevitable. We can have better things. We just need to demand them — again and again and again, until we get them!”
