On a broader, society level, solar power is a commonsense financial decision these days. The public health, climate, and environmental savings from using solar instead of fossil fuels are huge, and even if you didn’t include those, solar is now cheaper than fossil fuels in a number of places anyway.
If you just care about money, or assume that this is the ultimate bottom line, then this solar power pro should have you sold already, so you can stop reading now.
Protects our climate, air, and water: In the end, it really doesn’t matter how much money you have if you don’t have a livable climate, clean air, or clean water. And the scientific consensus is very clear by now: we need to cut carbon emissions drastically in order to protect our climate and this society, and solar power is a key way to do so. Similarly, solar power and wind power offer the most logical and cost-effective ways to cut pollution from electricity generation and also preserve our limited freshwater resources.
