Green Power

Written by Garnet McPherson

Green Power is electricity that is generated from resources such as solar, wind, geothermal, biomass, and low-impact hydro facilities. Conventional electricity generation, based on the combustion of fossil fuels, is the nation's single largest industrial source of air pollution. 

The increasing availability of green power enables electricity customers to accelerate installation of renewable energy technologies. As more green power sources are developed - displacing conventional generation - the overall environmental impacts associated with electricity generation will be significantly reduced. The more we shift to green power, the more we yeild positive results.

Choosing green power offers a number of benefits to businesses and institutions, including:

Environmental stewardship - Many innovative organizations are establishing environmental commitments to make their operations and practices sustainable. Choosing green power is a simple step towards creating a more sustainable organization.

Public image - Green power can help improve an organization's public image by demonstrating environmental stewardship.

Customer loyalty - Demonstrating environmental stewardship through green power may help increase an organizationÕs customer and investor loyalty.

Employee pride - Employees prefer to work for companies that give back to their communities and to the environment.

Power portfolio management - Because some green power sources have no fuel costs, green power can help protect your power portfolio from volatile prices of fossil-fuel-generated electricity.

Power reliability - On-site renewable generation can be a more reliable source of power than power distributed through the electric grid.

Green Power Options

Green power is available in four basic forms, the availability of which partially depends upon the status of electric utility restructuring in the state or province where the purchase is being made. There are  Blended products,  Block products,  Green tags or renewable energy certificates, aOn-site renewable generation.
 
Blended Products - Also known as "percentage products," blended products allow customers, primarily in states with competitive electricity markets, to switch to electricity that contains a percentage of renewable energy. The renewable energy content of blended products can vary from 2 percent to 100 percent according to the renewable resources available to utilities or marketers.

Block Products - Block products allow customers served by monopoly utilities to choose green power from the electric grid in standard units of energy at a fixed price, which is converted to a premium and added to their regular electric bill. Customers decide how many blocks they want to purchase each month.

Green Tags or Renewable Energy Certificates - Green tags allow customers to purchase the renewable attributes of a specific quantity of renewable energy. Green tags are sold separately from electricity and can be purchased for a location anywhere in the U.S. In this way, a customer can choose green power even if the local utility or marketer does not offer a green power product. One green tag typically represents the renewable attributes associated with one megawatt hour of green power.

On-Site Renewable Generation - Customers can install their own renewable energy generating equipment at their facility. On-site renewable generation can increase power reliability, provide stable electricity costs, and help manage waste streams. Furthermore, in many states, excess green power generated on-site can be returned to the electric grid, in effect allowing customers to obtain credit from their utility. (This is also known as "net-metering.")

Certification and Accreditation - Green power certification and accreditation programs help ensure that customers get what they pay for when they choose green power.
Green-e is a voluntary certification

What ever option you choose you will know that your decision can generate multiple benefits.
