Green Switch

Green Switch

How to plug in

Making the Green Switch is as easy as flipping a light switch. You can buy green power in 200-kilowatt-hour blocks. Each block you sign up to purchase will add $2 to your monthly power bill, and you can buy just one block or as many as you like. The green power you pay for will be added to TVA's electric system as part of the Valley's total power mix.* Why does green power cost more? Because while renewable resources like sunlight may be free, the technology used to capture the energy these resources produce is still more expensive than traditional power generation methods. By choosing to pay a little more for Green Switch. you help advance the technology and increase the amount of electricity generated from cleaner sources. In the spirit of renewability, the dollars from every block of green power you buy go directly back into Green Switch.

The Center for Resource Solutions (CRS), an independent, nonprofit organization, will perform an annual audit of Green Switch to verify that power from green power sources is sufficient to supply the amount of power sold.

How it works

windWind Power
Power out of thin air-it's no magic trick. Properly placed win turbines can generate electric power anywhere the wind blows steady and strong. Wind turbines use the momentum of moving air to quietly turn the large blades, which are attached to the shaft of an efficient electric generator.

sun2Solar Power
Strong enough to fry eggs from 93 million miles away, the sun is an incredible power source of energy. That's why we're collecting solar power with photovoltaic panels and transforming it into usable electricity. When rays of sunshine strike a solar panel. They give some of the electrons inside it more energy, which creates an electric current. At present the amount of energy derived from solar power is small, but we plan to grow Green Power Switch's solar component.   [Learn More]

methane2Methane Gas
There's treasure in your trash. In the start-up stage of Green Power Switch, methane gas from landfills will provide the largest source of its cleaner energy. If released directly into the atmosphere, the methane that landfills emit becomes a potent greenhouse gas, but using the methane gas as fuel to power an electric generator transforms the problem into a renewable energy solution that actually helps reduce air pollution.

How's this for environmental impact?
Buying two blocks of green power per month for a year (equals =)
recycling 480 pounds of aluminum (that's 15,322 cans) or
recycling 1,766 lbs. of newspaper
