Historically, wood was the main source of U.S. energy until the mid-1800s and was the only commercial-scale renewable source of energy in the United States until the first hydropower plants began producing electricity in the 1880s.
When did renewable energy become popular in the US?
From the late 1800s until today, fossil fuels—coal, petroleum, and natural gas—have been the major sources of energy. Hydropower and wood were the most used renewable energy resources until the 1990s.
Why doesn’t the US use more renewable energy?
It all comes down to cost and infrastructure. Ultimately, the biggest hindrance to the development of renewable energy is its cost and logistical barriers. Once the infrastructure for renewable energy sources grows, we will see it take off in popularity and use.

What are the two most important drawbacks of renewable energy?
Renewable Energy Can be Unreliable
Wind turbines require wind blowing, at least with minimum wind speed, to move their blades. Solar panels need clear skies and sunshine to get the heat required to generate electricity, and at night it isn’t collected.
