Amid the ongoing discussion about solar energy and its potential benefits, there has been surprisingly little talk about the effect that a warming planet is having on this resource. There is a direct correlation between the use of solar panels as an energy source and global warming. However, to understand this correlation, it is necessary to briefly explain the basic differences between solar panels.
There are two broad categories when it comes to different types of solar energy harvesting techniques. The first category is from photovoltaic panels—often referred to as PV panels. This method utilizes a component called a semiconductor. This semiconductor functions to convert sunlight directly into electricity. The second method is known as Concentrated solar power (CSP). It’s a technique that makes use of strong reflective mirrors to generate heat; This heat is then converted into power.
The impact that global warming will have on this planet is widespread and varied. Many systems—both natural and man-made—will undergo dramatic changes with increasing temperatures. Electricity obtained from the sun’s heat is especially susceptible to these changes—making it odd that it is so little talked about in discussions about global warming. Interestingly, the anticipated impacts of rising global temperatures are not all positive for the industry. As the planet’s temperature increases, weather patterns can change drastically.
Experts predict that in places like the American southwest, solar power output could fall by as much as 6% by 2080. Despite the fact that rising temperatures will seen like an extra boost for the industry, sometimes certain areas become more vulnerable to cloud cover. Clouds blocking sunlight is one of the most effective ways that weather can interfere with output from solar panels.
However, not all regions will experience a decline in output. In fact, many areas are looking to increase the amount of solar power they generate. Many parts of Europe, China, Australia and others are expected to see output increases of as much as 10%—from rising temperatures alone. These areas are quietly preparing for the changes scientists predict.
Many are doing research to find out what type of solar power will be optimal in the coming years. To implement this type of electricity harvesting effectively, it is necessary to have a group that looks forward to climate change during the planning process. Solar panels are not cheap, especially when implemented on an economic scale. This is where the difference between solar PV and CSP becomes an important topic. While both methods will generate energy wherever sunlight hits the surface, either method may be more or less effective depending on the specific environment in which they are used.
Luckily, the scientific community is doing new research on this subject, yielding new and useful information with every research that has been done before. This knowledge can help empower humanity; gives us the opportunity to take hold of the future and create the best scenarios with the tools we have, tools like solar energy.
