Green Power Your Next Event

For years, NC GreenPower subscribers have been able to offset the energy footprint of their home. Now you can do the same for events! At NC GreenPower, we encourage event planners to reduce their carbon footprint by helping them to “green up” their conference, wedding, party, or other special events. We enable you to offset the environmental impact with an equivalent purchase of renewable energy and/or carbon offsets through NC GreenPower, an independent, nonprofit organization who contracts with local generators.

Our online calculator lets you select the category of building your event is held in, the square footage committed to the event and the number of hours that energy will be consumed. Send a powerful message to your customers and guests by greening your event with NC GreenPower. Download our calculator methodology here.

You can also calculate the positive impact that your NC GreenPower contribution can make online with our Donation impact calculator, and calculate a carbon offset with our Driving Green Calculator. Or, simply contact us to provide you with a detailed estimate for your specific event!
