Overall US electricity generation has been relatively stable at around 4 PWh/year for the last 19 years, reflecting increasing energy efficiency even as our economy continues to grow. However, that relative stability belies a massive shift away from coal and towards gas, wind, and solar.
☀️ Solar Explosion
In the last decade, solar power has transformed from an experimental niche to one of the cheapest sources of power in the near-perfect conditions of the desert Southwest — although its intermittent nature will make further growth more difficult.
🌬️ The Rise of Wind
Wind generation has skyrocketed to become a major electricity source for the states of the windswept Great Plains. Our great offshore wind potential remains untapped for now.
☢️ Neglected Nuclear
Nuclear plants easily remain our largest and most reliable source of safe, carbon-free power — but instead of expanding, we are starting to retire plants early. Any serious decarbonization plan must address the regulatory, economic, and cultural hurdles that hold nuclear back.
