In Vermont, the electricity sector is largely characterized by more than half of its electricity being imported, at nearly 56%, which indicates dependency on external sources. The local electricity generation is predominantly low-carbon, making up about 44%. Hydropower is the leading source among the low-carbon energies, contributing nearly 27%. Other notable contributors include biofuels at over 7%, wind energy at around 6%, and solar energy, which supplies about 4% of Vermont’s electricity. This composition underscores Vermont's significant reliance on clean energy sources, which is a commendable effort in curbing emissions and promoting sustainable electricity generation.
Is Electricity Growing in Vermont?
However, Vermont's electricity consumption tells a tale of decline when viewed over the long term. With a current consumption rate of 8,822 kWh per person, the state is experiencing a decrease of 28% compared to its 2009 peak of 11,655 kWh per person. This downshift also extends to low-carbon electricity generation, which stands at 3,900 kWh per person, showing a substantial drop of 7,744 kWh per person from the record in 2009. This reduction is concerning as it may hinder Vermont’s ability to meet future energy demands through clean sources and reflects a downward trajectory that does not align with the growing global emphasis on transitioning to low-carbon energy systems.
Suggestions
To elevate its low-carbon electricity generation, Vermont can draw valuable lessons from regions that have successfully embraced particular clean energy technologies. Consideration could be given to increasing nuclear capacity, similar to New Hampshire's model where nuclear energy supplies 56% of electricity. Expanding solar energy generation is also a promising route; Vermont could look towards regions like Nevada and Lebanon, which generate 27% and 31% of their electricity from solar, respectively. Additionally, increasing wind energy potential could follow the examples set by Iowa and South Dakota, both of which generate more than half of their electricity through wind. These strategies would empower Vermont to fortify its clean energy portfolio, reduce dependency on imports, and significantly increase its low-carbon electricity generation.
History
The history of low-carbon electricity in Vermont highlights some notable trends, particularly with nuclear energy, which has faced multiple ups and downs. The early 2000s experienced growth in nuclear electricity generation, peaking in 2006. However, subsequent years saw fluctuations and an eventual decline by 2010. Hydropower had its own share of volatility, with increases in some years and decreases in others, yet it remains a significant component of Vermont’s clean energy mix. Other low-carbon sources like biofuels and wind gained traction starting around 2013, symbolizing a gradual, albeit limited, diversification of Vermont's clean energy capacity. The fluctuating history of its low-carbon sector highlights the need for a more stable and robust approach, particularly in expanding sustainable nuclear and solar capacities, to ensure a steady and growing clean electricity supply.
