How The U.S. Can Build A 100% Clean Grid
CNBC・2 minutes read
The U.S. electric grid, designed for a fossil fuel-based world, needs to transition to a more distributed system to support renewable energy sources, requiring major investments and modernization. Companies like OhmConnect are incentivizing energy savings, while utility companies face challenges in upgrading the grid to incorporate renewables, with a push from individuals, corporate customers, and investors towards carbon-free electricity.
Insights
- The U.S. electric grid, established in the 1880s, is outdated and designed for a fossil fuel-based world, hindering the transition to renewables and necessitating significant investments to modernize for a more distributed system that allows for individual and company power generation through solar panels and electric vehicle batteries.
- Utility companies in the U.S. face challenges in coordinating massive grid upgrades due to diverse ownership structures and regulations, but pressure from various stakeholders is driving them towards incorporating more renewables. Companies like Southern Company, Dominion Energy, Duke Energy, and Xcel Energy are working towards achieving net zero emissions by 2050, aligning with President Biden's goal of a carbon-free electricity sector by 2035, with policy tools like carbon pricing and investments in grid-scale energy storage and technological advancements playing a crucial role in accelerating this transition.

Recent questions
What is the current state of the U.S. electric grid?
The modern U.S. electric grid connects to 7,300 major power plants through 160,000 miles of high voltage transmission lines and millions of miles of low voltage lines, serving over 150 million customers. It was designed for a fossil fuel-based world, with power flowing one-way from large power plants to consumers, hindering the transition to renewables.
Why is a more distributed grid necessary?
A more distributed grid is needed to allow individuals and companies to generate, store, and sell electricity through solar panels and electric vehicle batteries. This shift would enable a more efficient balance of supply and demand, moving away from the traditional one-way flow of power from large plants to consumers.
What are the challenges posed by distributed generation like solar panels?
Distributed generation, such as solar panels, poses challenges like the need for upgraded transformers to handle reverse electricity flow and managing peak demand efficiently. These challenges must be addressed to ensure the effective integration of renewable energy sources into the grid.
How can consumers save money and enhance grid efficiency?
Demand response programs and time-variable pricing can help consumers save money by adjusting energy usage during peak demand times, enhancing grid efficiency. These initiatives encourage more efficient energy consumption and contribute to a more sustainable grid system.
What are utility companies doing to achieve net zero emissions?
Utility companies like Southern Company, Dominion Energy, Duke Energy, and Xcel Energy are working towards achieving net zero emissions by 2050. Despite facing logistical challenges, these companies are making efforts to incorporate more renewables into the grid, aligning with the goal of a carbon-free electricity sector by 2035 set by President Biden. Policy tools such as carbon pricing and investments in grid-scale energy storage and technological advancements are key components of this transition.
