If you wonder why Arizona Public Service is blasé about solar on your roof, the cost chart in this article shows why: utility scale solar costs less. But a UBS analyst thinks renewable energy will “effectively be free” by 2030.
The industry is still expected to rise in the coming years. A report last month from the Energy Information Administration stated that wind and solar, which provided three percent of the United States' energy generation in 2018, will comprise 13 percent of generation in 2020. Around 18 percent of the 24 gigawatts of power set to come online next year is expected to come from photovoltaic solar panels.
