Why can't we just use less electricity, instead of developing new energy sources such as offshore wind?

Much of our world relies on steady electricity to function — including hospitals, schools, businesses, and homes. Power outages can cause irreparable and life-threatening (1) harm to people and communities (2). Additionally, reducing our reliance on fossil fuels by moving towards electrification of everything (think home heating, cars, buses, appliances, etc.) would roughly double (3) electricity demand. Not only do we need to replace existing dirty energy with renewables, but we need even more renewably-generated electricity to offset fossil fuels in newly electrified sectors. Therefore, it is highly unrealistic that we will stop needing electricity entirely. 

 

However, there is a lot we can do to reduce our electricity consumption; for example, we can utilize more efficient products, use electricity at times of the day when it is more plentiful, and design our communities to require less energy (such as building good public transit and pedestrian infrastructure so that people have less of a need to drive—even electric

cars!). In addition, many new technologies, such as artificial intelligence and cryptocurrency, require staggering amounts of electricity (4) and should be regulated to reduce their demand.

 

Thanks to activism by local environmental organizations dating back to 2012, Humboldt County is currently developing a Climate Action Plan (5) that will encourage many of these actions. California has implemented a variety of energy efficiency policies and programs (6), such as the Building Energy Efficiency Standards (7), the Energy Savings Assistance Program (8), and the Energy Upgrade California program (9). At the federal level, Democratic administrations have long advocated (10) for stricter rules around energy efficiency. To take just one recent example, on April 30, 2024, the Biden administration finalized new energy efficiency standards (11) for household water heaters that will save homeowners money and reduce their energy use. Because of efficiency standards like these, per capita energy use in the U.S. has actually fallen (12) from its peak in the 1970s.

Graph of energy use per person in the United States from 1965-2022, measured in kilowatt-hours (kWh) per person use of primary energy using the substitution method. Per capita energy use was ~75,000 kWh in 1965, ~85,000 kWh in 1970, ~81,000 kWh in 1980, ~85,000 kWh in 1990, ~85,000 kWh in 2000, ~80,000 kWh in 2010, and ~72,000 kWh in 2022. The peak of per capita energy use was 1970, and 2022 shows the lowest per capita energy use across the past ~60 years.
