Frequently Asked Questions
How Do Green Energy Suppliers Compare in Price to Traditional Utilities?
Green energy prices vary by region compared to traditional utilities.
While renewable options require higher upfront costs, they typically offer long-term savings.
Solar panels pay for themselves in 5-20 years, and wind energy costs just 1-2 cents per kWh after installation.
Renewable energy costs are falling 10-15% annually, while traditional electricity rates rise 2-3% yearly.
Many regions offer incentives like tax credits and net metering to offset costs.
What Certification Standards Verify a Company’s Renewable Energy Claims?
Several certification standards verify renewable energy claims.
Green-e Energy guarantees RECs aren’t double-counted and requires annual audits.
The I-REC Standard operates in over 50 countries and enables credible global claims.
EKOenergy Label verifies 100% renewable sources with additional sustainability criteria.
The Low Impact Hydropower Institute certifies facilities that meet environmental and social standards.
These certifications help consumers identify reliable renewable energy providers.
Can I Switch to Green Energy Without Installing New Equipment?
Yes, consumers can switch to green energy without any new equipment.
Many utilities offer green power programs where customers simply enroll online for a small premium.
Community solar projects allow people to subscribe to local solar farms without installing panels.
Purchasing Renewable Energy Certificates (RECs) is another option that supports clean energy generation.
These methods use the same electrical service and billing systems already in place.
How Reliable Is Green Power During Extreme Weather Events?
Green power can be reliable during extreme weather events. Renewable energy sources often continue working when traditional systems fail.
While prolonged cloudy or windless periods present challenges, diversification helps. Solar panels perform well during heat waves, and microgrids provide localized power during outages.
Smart grid technology improves response times. Energy storage and weatherization of equipment are making green power increasingly dependable when extreme weather hits.
What Percentage of Green Suppliers Use Locally-Sourced Renewable Energy?
The percentage of green suppliers using locally-sourced renewable energy varies by category.
Utility green power programs lead with 96% sourcing locally or regionally. Community solar programs are highly local, with 98% located within utility service territories.
Corporate renewable energy buyers show 65% prioritizing local sources. Green energy marketers lag behind, with 55% offering locally-sourced options.
