Building a Sustainable World is Hard Work
Building a Sustainable World is Hard Work
A Note from Arnold Leitner, CEO
Today, atmospheric CO2 concentration is 424.18 ppm or 0.04%.
It seems like a small number, but CO2 is the only gas in the atmosphere that traps heat. The rest, 99.96% of the atmosphere, has nothing to do with the Earth’s greenhouse effect.
In 1991, I began to work on solar technology, and the value was 355 ppm. In my career, atmospheric CO2 levels have risen nearly 20%.
That is alarming. To give you an example, our healthy body temperature is 98 F. If it were to rise by 20%, it would be 118 F. This means we would be dead. And planet Earth is dying, too.

Yesterday, the International Energy Administration reported that coal consumption reached a new peak and will remain at near-record levels for years.
When people who care about climate change read news like this, they feel helpless and resign to the inexorable momentum of the status quo. They even turn to escapism, like life on Mars.
There is no quick solution. No one has it.
Instead, saving the planet and maintaining humanity’s incredible achievements will be complex and hard work. But it can be done, and we have the technology.
YouSolar’s nanogrid will be a key piece, and if you have read our update on 11 December on the coming electricity crisis, it is even the first and most important piece.
