When you replace light bulbs or entire light fixtures in your home with ones that have earned the government's ENERGY STAR, you help preserve energy resources and reduce the risks of global warming while saving money and time buying and changing lights in your home.
ENERGY STAR qualified lighting provides bright, warm light but uses about 75% less energy than standard lighting, produce 75 percent less heat, and lasts up to 10 times longer.
Standard 100 watt Incandescent light bulb can be replaced by a 23-30 watt energy efficient compact fluorescent (CFL)
Standard 75 watt Incandescent light bulb can be replaced by an 18-25 watt energy efficient compact fluorescent (CFL)
Installing Compact Fluorescent Bulbs can save from 20 to 30 kWhs per year or more depending on size. At today's electric rates that is $4 to $6 per year per bulb. The bulbs also last 10 times longer than an incandescent so the savings there can easily pay for the cost of the bulb.
To save the most energy and money, replace your highest used fixtures or the light bulbs in them with energy-efficient models. The five highest use fixtures in a home are typically the kitchen ceiling lights, the living or family room table and floor lamps, and outdoor porch or post lamp.
If every American home replaced just one light bulb with an ENERGY STAR qualified bulb, we would save enough energy to light more than 3 million homes for a year, more than $600 million in annual energy costs, and prevent greenhouse gases equivalent to the emissions of more than 800,000 cars.
If every American home replaced their 5 most frequently used light fixtures or the bulbs in them with ones that have earned the ENERGY STAR, we would save close to $8 billion each year in energy costs, and together we would prevent the greenhouse gases equivalent to the emissions from nearly 10 million cars.
The energy used in the average home can be responsible for more than twice the greenhouse gas emissions of the average car. When you use less energy at home, you reduce greenhouse gas emissions from power plants and help protect our environment from the risks of global climate change.
Energy Efficient CFLs are available in various shapes and sizes to fit most fixtures within the home both interior and exterior.
