The Clean and Secure Grid would use existing technology and build upon current infrastructure to create a more efficient and environmentally sound electrical cable network across the lower 48 states that would connect local and regional alternating current systems that are currently isolated. Over the last six years, Dr. Alexander MacDonald, former Director of NOAA’s Earth System Research Laboratory, lead a team of scientists to research and construct a cost optimized strategy to reduce carbon emissions of electricity generation by up to 78% in the power sector by transmitting regionally produced wind and solar energy, integrated with natural gas, across long distances to far away energy markets using an underground high voltage direct current (HVDC) grid system.
Not only would the underground power lines transmit electricity more efficiently, they would also be more resilient to solar storms and terrorist or rogue state attacks. A geomagnetic solar storm, much like the Carrington event of 1859, could destroy the existing grid system leaving everyone without power for at least several years. These storms could happen at any time and are impossible to predict. A terrorist organization or rogue state could cause a similar effect on a smaller scale by detonating an electromagnetic pulse (EMP) over any area of the country. The solutions to this problem are burying the grid under several feet of soil that would protect powerlines from natural or human caused threats and using alternate routing paths that direct the EMP charge away from critical components.
The new infrastructure would be privately financed upfront and paid for by consumer utility bills over time. Including the added user fee for the new grid, the cost of electricity would only be one cent higher per kilowatt-hour, a small price to pay for greater national security and a drastic reduction in greenhouse gas emissions.
- A new market for thousands of long term jobs to build, operate, maintain the national grid and renewable energy infrastructure
- Lower dependence on foreign energy sources
- Greater resilience to extreme weather events due to the underground placement of electrical cables.
Powerlines would follow existing rights of way to reduce legal complications and expedite the construction. The Clean and Secure Grid would be built by existing HVDC cable manufacturing plants throughout the United States and would create a highly competitive manufacturing market for wind turbines and solar panels, leading to sustainable and high paying jobs across the country.
