My Journey Towards Self-Reliance, Part I: High Efficiency Lighting

Formerly "Moving Towards Self-Reliance, Part I: High Efficiency Lighting"

I've been slowly working towards my goal of being self-reliant in food, water, energy and finances.  Today, I want to discuss how to become more energy-efficient as part of the larger goal of becoming self-reliant.  More specifically, I want to talk about high efficiency lighting.

Do Light Bulbs Really Use That Much Energy?


According to the American Council for an Energy-Efficient Economy, artificial lighting accounts for at least 10% of the typical American's total energy usage in their homes.  Various other sources claim even larger figures, with some experts citing that lighting can make up as high 30% of the annual electricity usage.

It's hard to imagine that a simple light bulb would use that much of total energy a house expends throughout the year.  Indeed, even the most inefficient light bulbs don't use that much power compared to other appliances, like refrigerators or clothes dryers.

Hardly anyone uses just one light bulb in most rooms in a typical house, however.  The combined sum of wattage used by light bulbs can quickly surpass that of larger, power-hungry appliances, especially when left on for long periods of time.

Obviously, turning off lights when not in use will save energy and money.  However, most of us like having artificial lighting, especially at night when we would accomplish nothing without said lighting.

Artificial lighting may be necessary, but we can choose specific types of light bulbs to significantly reduce our energy usage.
