Solar panel recycling in the US — a looming issue that could harm industry growth and reputation – pv magazine USA
The downside is that solar panels have finite lifespans; are difficult and expensive to recycle; and are being decommissioned in increasingly large numbers.

100 year flood 💧
100 year flood 💧
A 100 year flood is one that has a 1% chance of happening in any particular year. That is the level of risk that the government declares as within a flood plain, and requires flood insurance to purchase a government backed mortgage.
You might think that a 100 year flood occurs every one hundred years or your guaranteed a single flood every 100 years but that’s not how probability works. A 100 year flood only has a 63.3% chance of happening at least once each century.
The formula for probability over time is:
C = Chance in percent of winning
T = The number of times your running the probability
P = Percent chance of winning over time
(1 - (1-C) ) ^ T = P
(1- (1 - 0.01) ) ^ 20 = 0.182 or 18.2% flood risk over 20 years.
A 100 year flood plain has a 63.3% chance of flooding over 100 years, 86.6% chance over 200 years, and 95.0% chance over 300 years.

How GPS Actually Works
We already live in the future. We have handheld devices that use satellites to pinpoint our precise locations almost anywhere on the planet. But have you ever wondered just how GPS works?
GPS devices don’t actually contact satellites and transmit information to them. They only receive data from satellites – data that’s being always-transmitted. However, GPS isn’t the only way devices can determine your location.
How long for the stock market to return big on investments
The stock market is one of the greatest wealth-building tools that exists, as long as you follow a few key rules. You'll need to know what you're investing in, watch your fees, build a diversified portfolio, and invest for the long term if you want the best chance to build wealth in the market.
You'll also need to do one of two other things: Invest early, or invest a lot. The good news is, you don't necessarily need to do both if your goal is to invest your way to a $1 million nest egg.
