The use of solar energy has been growing by leaps and bounds in recent years. It is the fastest growing source of energy in the U.S. Solar panels have a useful life of about 25 to 30 years and there are growing numbers that have been around that long. They contain valuable materials, including silver, copper, and aluminum, as well as some hazardous materials, so just committing them to landfills is a bad idea from many perspectives.

Recycling solar panels is a relatively new but increasingly important business. At the present time, roughly 90% of panels that have lost their efficiency due to age or that are defective end up in landfills because that is much cheaper than recycling them. The best option is to reuse them where their reduced efficiency is acceptable. This includes in developing nations or in other places that are able to make use of the lower power in exchange for lower installation cost.

Estimates are that the area covered by solar panels in the U.S. that are due to retire by 2030 would cover about 3,000 football fields. The amount of potential waste contained in all of those panels is quite substantial.

There are new companies dedicated to solar panel recycling such as one called SolarCycle that are trying to change this situation. It is much more expensive to have SolarCycle take away solar panels than to send them to landfills, but it is difficult to find landfills that accept panels and many clients want to minimize the environmental impact of their old panels.

Only 10% of retired solar panels are currently recycled. That that is likely to change as economics and regulations continue to evolve.

While there are still some people who remain dubious about the reality of climate change, insurance companies are not among them. And, in fact, insurers are warning that climate change could make coverage for ordinary people unaffordable.

Munich Reinsurance, the world’s largest reinsurance firm, blamed global warming for $24 billion in losses from California’s recent wildfires. Such costs could soon be widely felt as premium rises are already under discussion with insurance companies having clients in vulnerable parts of the state.

With the risk from wildfires, flooding, storms and hail increasing, the only sustainable option for the insurance industry is to adjust risk prices accordingly. Ultimately, this may become a social issue. Affordability of insurance is critical because if rates go up too much, many people on low and average incomes in some regions may no longer be able to buy insurance.

The great majority of California’s 20 worst forest fires since the 1930’s has occurred since the year 2000 driven by abnormally high summer temperatures and persistent drought. The reinsurance giant analyzed decades of data with climate models and concluded that the fires are likely driven by climate change.

It isn’t just wildfires. Insurance premiums are also being adjusted in regions facing an increased threat from severe convective storms whose energy and severity are driven by global warming. These include parts of Germany, Austria, France, southwest Italy, and the U.S. Midwest.

Linking extreme weather events to climate change is a bit like attributing the performance of a steroid-using athlete to drug use. The connections are clearer in patterns than in individual disasters. But the pattern these days is pretty clear.
