How to switch to LED bulbs and electric

An 86-year-old clean energy advocate shares how switching to LED bulbs and electric vehicles can cut household energy use. He replaced almost every bulb in two houses and a garage, first with fluorescents and then with LEDs, to achieve major efficiency gains.

He bought 200 60-watt equivalent LED bulbs during an IKEA special years ago, paying just 50 cents each. While LED bulbs now cost around $2.50 at IKEA, 60W-equivalent versions can be found online for as little as $1.28 each. The shift from incandescent to fluorescent lighting was a step forward, but the move to LEDs delivered even greater savings. A fluorescent bulb uses 25% of the energy of an incandescent bulb with the same light output. An LED bulb uses only 10%. LEDs are also supposed to last 20 years. The advocate recently found a burned-out 2-ft fluorescent tube in a closet and replaced it with an LED, noting that some hardware stores no longer stock the older fluorescent tubes.

Transportation electrification as a visible commitment

Switching to battery electric vehicles is framed as both a practical efficiency gain and a public statement. "The most important thing you can do to be a clean energy evangelist is to replace your gas vehicle with a pure battery electric vehicle," the author said. A BEV does not burn fossil fuel while operating, is 90% efficient, and seldom uses its brakes. He made small silver '100% Electric' stickers for other BEV brands to place on his car, reinforcing that "Driving a BEV is a visible statement that everyone around you will observe."

All new Teslas have an EPA battery range of over 300 miles, but used models offer a lower-cost entry point. The advocate's son bought a 7-year-old Tesla Model 3 Performance for $15,000, with good range and warranty remaining. Charging infrastructure has improved, with all US EV brands now able to charge at most newer Tesla Superchargers. Some models, like the Chevy Bolt EV which starts at $27,600, now come with a native Tesla (NACS) socket and do not require an adapter.

E-bikes complete the clean mobility toolkit for daily trips

Electric bikes are recommended as a bookend transportation action for short errands. The advocate uses an ebike for trips when his wife drives the Tesla, such as picking up prescriptions, going to the gym, or grocery shopping. Mountain ebikes can drive on gravel, be driven off the road edge in emergencies, provide smoother rides on bumps, and jump curbs. For those not athletically able to ride a two-wheeler, electric trikes or 3-wheel recumbent bikes are practical alternatives.

Author’s personal EV use shows long-term advocacy

A decade of EV driving illustrates a sustained commitment. The advocate has driven an EV to car shows and parades for 10 years and now owns a 2026 Tesla Model Y. He notes financing options have evolved, with interest rates on new models rising slightly.

All new Teslas have Hardware V4 capable of running 'Full Self Driving' V14, available for a $99 monthly subscription. Permanent FSD subscriptions are no longer available, though Teslas sold between mid-2023 and spring 2026 may have Hardware 4 and a permanent FSD V14 subscription. The advocate cautions that most used car lots do not know how to sell EVs, often failing to communicate key details like battery range, motor type, hardware version, or FSD subscription status.

The author also recommends switching fossil gas or resistance electric water heaters to heat pump water heaters. He suggests these ways for readers to become clean energy evangelists in their own communities.
