Have you ever wanted to power your home or office with renewable energy, but thought it was too expensive? Or you didn't want to deal with installing and maintaining equipment?
Now there is a way that everyone can use solar, wind, and other renewable energies, at a fraction of cost. Even renters can power their homes with renewable energy.
Renewable energy certificates (aka green tags, green energy certificates, or tradable renewable certificates) make it easy and inexpensive for anyone to reduce or eliminate environmental impact of their electricity use.
Each certificate represents delivery of a specific amount of renewable power (usually one megawatt-hour) into a regional or national energy "grid." This replaces non-renewable fossil fuels that would have otherwise been used with non-polluting energy from solar, wind, biomass, and other renewable sources.
While renewable energy you pay for may not flow through wires in your own home, resulting overall benefit to environment is same as it would be if you installed solar panels or wind turbines directly on your own property.
The certificates are purchased in addition to paying your regular energy bill. So it doesn't cost less than standard electricity, but it’s a small premium to pay to keep toxic pollutants produced by burning of fossil fuels out of environment. And it supports market for renewable energy as a whole, which ultimately will bring price down for renewable energy and make it more generally available.
