Solar panels convert the sunlight hitting your roof directly into electricity, with no smog-forming pollution or climate-warming carbon dioxide emissions. Compared to a big, industrial power plant burning coal dug up from the ground, solar power systems seem like magic – but how do they actually work with your home electrical system?
The combination of solar and energy efficiency is at the heart of what the Department of Energy calls “Zero Energy Buildings” or ZEBs, defined as “an energy-efficient building where, on a source energy basis, the actual annual delivered energy is less than or equal to the on-site renewable exported energy.”
The decision to improve the efficiency of your home usually starts with wanting to save on your energy bills – but the good reasons definitely don’t stop there.
The Earth’s climate is changing, and human activity is the main cause. 97% of climate scientists agree that global warming trends are clear and “extremely likely” due to human activities, most prominently the rising emissions of carbon dioxide from the burning of fossil fuels.
Adding batteries to your home energy system allows you to use your solar power when it’s most useful and valuable instead of whenever the sun shines, increasing the value of your rooftop solar system in two big ways.
Over 1 million homeowners in the U.S. have gone solar, and it’s not just people that care about the environment. Solar has become such a popular, mainstream investment because it can save you a lot of money on your electricity bills.
The available options for cost-effective renewable energy are increasing rapidly as technology matures. Here is a quick overview of some of its main sources.
As modern society has evolved over the years, we have become more and more dependent on a variety of fuels including coal, gas and petroleum. See how the drive for energy independence can benefit us all.
Declining equipment costs, more accessible financing and powerful investors have made home energy improvements easy. See how the industry has reached its tipping point.
Thanks to recent advances in solar panel technology, solar water pumps can be used in a number of places. The following information can help with your decision.
Solar attic fans are a great way to encourage airflow and reduce heating and cooling costs in your home. Read these tips before your next home improvement project.
