Illinois-based natural gas and electricity company Nania Energy is now offering renewable energy certificates (RECs) to its clients. RECs may be purchased through fixed energy quantity blocks, which involves purchasing a set amount of 100% renewable energy power.
Customers can elect to purchase green power as a fixed percentage of their monthly electricity usage, designating anywhere from 1% to 100%. This selection is priced either per kWh or as a percentage of a company's initial expense. The cost for this green power is calculated monthly based upon a customer's usage.
Additionally, customers can select specific sources of green power, such as wind, hydro or solar. According to Nania, these specific designations add significant cost to any green power purchase.
